1.2	Cruise Summary Information

1.2.1 Summary

In the afternoon of 17 June RV Pelagia departed from Texel, and headed for 
the Bay of Biscay. We arrived at the northern Biscay continental slope in the 
early evening of 19 June. Test stations with the CTD-rosette system were 
performed there on 19 and 20 June in order to establish the functioning of the 
newly developed sampler closing system. 

During the night an echo sounder survey of the continental slope was carried 
out, in the afternoon of 20 June the ADCP bottom lander was deployed on the 
continental slope at an uncorrected depth of 835 m. The bottom slope was 
estimated to be slightly less than 5_. After two CTD stations near the lander 
deployment site and the deployment of 5 ARGOS drifters over the continental 
slope course was set to the mooring section deployed in 1995. 

On both 21 and 22 June all 8 current meter moorings (BB1 to BB8) were 
recovered. Serious internal damage due to leaking was observed on 4 of the 
13 NBA current meters. The cause of the leakage was found to be tiny cracks 
in the PVS bolts filling the empty sensor holes in the in instrument cone. 
However data from 2 of the 4 damaged current meters could be recovered. 
All 19 Aanderaa current meters as well as the ADCP were found to be in 
good order. During the nights of 21 and 22 June extra echo sounder surveys 
were carried out over the continental slope in order to extend the information 
on the topographic structure near the mooring line as observed in 1995. 

After a final test station on the morning of 23 June it was decided that the new 
sampler closing system did not function reliable, and the old G.O. rosette 
system was reinstalled. That same morning the survey of the large scale 
hydrographic section A started near 46_56'N, 6°W. The survey of this section 
was ended at 29 June over Goban Spur. Small-scale hydrographic section B 
over the continental slope south of Goban Spur was surveyed on 29 and 30 
June. After ending this section course was set to Brest. During this passage 
an extra echo sounder survey was carried out of the site were the ADCP 
lander had been deployed. The Pelagia arrived in Brest about noon of July 1. 
In port C. Veth disembarked and F.P. Lam embarked as a replacement. Also 
some supplies for the moorings to be deployed were brought in as well as 
"patches" to overcome problems with the newly updated SUN operating 
system of the computer network.

On 2 July Brest was left after breakfast. In the afternoon and evening 
moorings T2 and T1, fitted with current meters and thermistor strings, were 
deployed over the continental shelf, and shortly before midnight the 25 hours 
CTD yo-yo station over the continental slope for the "hunting" of solitons in 
the seasonal thermocline started. This time series station coincided with 
spring tide. After finishing the yo-yo station, shortly after midnight on 4 July, 
course was set to the position of mooring T1 which could be recovered 
although part of the buoyancy was lost. From mooring T2 no trace could be 
found, also not after sweeping the mooring area with a grappling iron on a 
long steel wire for about 7 hours. Mooring T2 is considered to be lost.

Moorings BB9 to BB16 were deployed on 5 to 7 July on two lines across the 
continental slope after performing echo sounder surveys of the mooring 
sections. Hereafter the hydrographic survey was continued with several 
sections across the continental slope. The first of these sections, C was in the 
south-eastern corner of the Bay of Biscay, in the direction of Biarritz, while 
section D was close to, and nearly parallel to the section where moorings 
BB13 to BB16 were deployed before. Section E was surveyed on 11 and 
early 12 July. In the afternoon of 12 July the ADCP bottom lander was 
recovered. The lander surfaced upside down, but due to the fair weather it 
could easily be turned in the right position before hoisting the instrument 
aboard. In the night from 12 to 13 July an echo sounder survey of the 
continental slope was carried out steaming from the lander position towards 
the first station of hydrographic section F. The survey of the latter section was 
finished in the morning of 14 July. On the last two stations of this section it 
was not possible to take water samples due to the final break down of the 
G.O. rosette sampler. After finishing section F course was set towards Brest, 
via the area of the ADCP lander deployment for a last echo sounder section. 
On Monday morning 15 July R.V. Pelagia arrived in Brest for debarkation of 
the scientific crew.

1.2.2 Cruise Track

The cruise was carried out in the Bay of Biscay east of 12°W. The cruise 
track is shown in figure 1.

1.2.3 Number of Hydrographic Stations

A total of 91 hydrographic casts was collected (fig. 2). At the hydrographic 
stations the SBE9/11+ CTD was lowered with a speed of about 1 m/s. Due  to 
the use of a bottom indicator switch we were able to sample to within quite a 
short distance from the bottom, 4 m until station 60, and 6 m afterwards. After 
station 27 damage at the till then unused part of the CTD cable was 
discovered. Thereupon it was decided to limit the veering of the CTD cable to 
4780 m, leaving only about the lowest 200 m of the deep basin out of reach 
from the observations. This applies only to stations 28 to 33 of section A. The 
CTD system was fitted with a sensor for pressure, with artificially flushed 
sensors for temperature, conductivity, and oxygen, and sensors for light 
transmission and fluorescence. An extra suite of not-flushed temperature and 
conductivity sensors was fitted in the system too. During the down-casts the 
data from the sensors were collected and stored on computer hard disk with 
data cycle frequency of 24 Hz. 

 

Figure 2.	Distribution of hydrographic stations and sections.


1.2.4 Hydrographic Sampling

During the up-cast of each CTD/rosette station water samples were taken. 
The vertical resolution of these water samples was 250 m in deep water with 
a better resolution in the upper 1200 m and at shallower stations. From the 
samplers water was drawn for the determination of dissolved oxygen, 
nutrients (silica, nitrite, nitrate and phosphate) as well as salinity. At sampler 
positions 2, 4, 6, and 8 reversing racks were mounted, fitted with SIS 
reversing electronic thermometers and SIS reversing pressure sensors. 
Additionally at a limited number of stations an SBE35 temperature sensor 
was used to record the water temperature at the closing of each sampler 
bottle. The vertical distribution of the sampling locations is indicated in figure 
3.

1.2.5 Drifters and Moorings

A total of 5 ARGOS surface drifters were deployed, on 20 June 1996, over 
the continental slope near 48°N, 8_20'W. These drifters (ptt ID numbers 
16118 to 16122) were standard WOCE/TOGA surface drifters manufactured 
by Clearwater Inc., each fitted with an 8 meter holey sock drogue at an 
average depth of 15 m. Each drifter has a temperature sensor as well as a 
submergence sensor. For the following 6 month the drifters mainly moved in 
SSE direction towards the Spanish continental margin.

Eight current meter moorings, deployed in 1995 on a line from the continental 
slope to the abyssal plain (BB1 to BB8), were recovered. Three short-term 
moorings were deployed (ADCP lander, T1, and T2) were deployed from 
which two could be recovered; mooring T2 was lost. Eight newly prepared 
current meter moorings were deployed over the continental slope in the SE 
Bay of Biscay (BB9 to BB16).

The positions of the drifter deployments and of the moorings is indicated in 
figure 4.

1.4	Scientific Programme and Methods

The principal goal of the research carried out during the cruise was to 
establish the structure, course and transport of the eastern boundary current 
in the Bay of Biscay, as well as the hydrographic structure of the Bay of 
Biscay and the nearby eastern North Atlantic, as it is affected by the eastern 
boundary current. For this purpose a hydrographic survey has been carried 
out in the Bay of Biscay up to 12°W, 8 long term current meter moorings and 
5 ARGOS surface drifters have been deployed. The hydrographic survey 
covers a large part of the WOCE Hydrographic Research Programme repeat 
area AR12. 

The CTD-rosette frame was fitted with lead filled steel pipes in order to 
secure a fast enough falling rate. This package was lowered with a velocity of 
about 1 m/s, except in the lowest 100 m, where the veering velocity was 
reduced. Measurements during the down-cast went on to within 4 m from the 
bottom, until the bottom switch indicated the proximity of the bottom. During 
the up-cast water samples where taken at prescribed depths, when the CTD 
winch was stopped. After each cast the CTD/rosette frame was placed on 
deck. Subsequently water samples were drawn for the determination of 
dissolved oxygen, nutrients and salinity, and the readings of the electronic 
reversing thermometers and pressure sensor were recorded.

Additional to the main hydrographic research programme ADCP observations 
have been carried out by means of a benthic lander to study the low 
frequency turbulent mixing over the continental slope. Short term high 
frequency temperature observations have been performed with moored 
thermistor strings and with CTD yo-yos to study internal solitons and other 
internal waves in the seasonal thermocline over the continental slope and the 
nearby continental shelf, generated by tide-topography interaction. 




1.4.1 Preliminary Results

The raw data, as collected during the cruise, have been processed after the 
cruise at NIOZ, Texel, as described in chapters 2 and 3. An overview of the 
preliminary results is given below.

 

Figure 5.	Vertical distribution of potential temperature (THETA) and 
		salinity (CTDSAL) from all CTD down-casts, sub-sampled every 
		50 dbar.

The vertical distributions of potential temperature (THETA) and salinity 
(CTDSAL) show a lot of variation between 500 and 2000 dbar (fig. 5), This is 
due to the presence of variable amounts of Mediterranean Sea Water (MSW) 
with a salinity maximum at about 1000 dbar and Labrador Sea Water (LSW)  
with a salinity minimum at about 2000 dbar. The highest salinities at 2000 
dbar are observed over the continental slope, probably due to vertical 
boundary mixing with the saline MSW core. At about 2400 dbar North East 
Atlantic Deep Water (NEADW) is found, characterized by a relative salinity 
maximum, although even higher salinities are found over the continental 
slope, probably also due to boundary mixing with MSW. Between 3000 and 
5000 dbar the nearly homogeneous low salinity Lower Deep Water (LDW) is 
found. This vertical stratification also can be observed in the potential 
temperature-salinity plot (Fig. 6), while combination with the potential 
temperature-potential vorticity plot (Fig. 6, second plot) indicates that 
overlying the MSW core and the permanent pycnocline horizontally nearly 
homogeneous Mode Water is found with a low vertical stratification at 
potential temperatures around 11.5 C. The overlying seasonal pycnocline is 
characterized by high potential vorticity values at temperature over 12.5°C.  
At the level of the salinity minimum due to the presence of LSW (~3.5°C) no 
clear minimum in the potential vorticity distribution could be discerned. 

 

Figure 6.	Diagrams of salinity and potential vorticity versus potential 
		temperature. The data are from all CTD casts, sub-sampled 
		every 50 dbar.

 

Figure 7.	Distribution of the Sea Surface Temperature (SST), as observed 
		with the AQUAFLOW thermosalinograph system. The thick line 
		indicates the position of the 200 m isobath, while the dots show 
		the ship track.

The distribution of the Sea Surface Temperature (SST, Fig. 7) shows SST 
values in the range between 14.5 and 19°C. The coldest surface water is 
found over the western Celtic shelf edge near Goban Spur, and the warmest 
water in the SE corner of the survey area. Over the deeper parts of the Bay of 
Biscay the SST amounts to about 17°C. The largest SST gradients are found 
perpendicular to the Celtic Shelf edge over the slope and abyssal plain. 
Although not completely clear due to the lack of SST data over the 
continental shelf the SST distribution suggests that an SST minimum is 
connected to the position of the continental break.

The distribution of the Sea Surface Salinity (SSS, Fig. 8) shows a picture 
different from the SST distribution, with the highest SSS gradients near the 
shelf edge in the SE part of the survey area. This is due to the presence of a 
thin surface layer, considerably diluted by river runoff from the nearby 
continent. The SSS in the centre of the Bay of Biscay is about 35.65, with 
values of 35.55 to 35.60 over the Celtic shelf edge. Salinities below 35 were 
observed in the coastal water near Brittany.

		AQUAFLOW thermosalinograph system. The thick line indicates 
		the position of the 200 m isobath, while the dots show the ship 
		track.

The vertical distribution of the dissolved oxygen concentration (OXYGEN, Fig. 
9) reflects the vertical distribution of water types described above. The MSW 
layer is characterized by an OXYGEN minimum of about 185 µmol/kg. While 
in the LSW core near 2000 dbar maximum OXYGEN values of over 
270 µmol/kg are observed at potential temperature of about 3.5°C. Over the 
continental slope this OXYGEN maximum is decreased or absent, probably 
due to increased vertical mixing. In the low potential vorticity Mode Water 
layer near THETA _ 11.5°C relatively high OXYGEN values of about 
240 µmol/kg are observed, with even higher values in the seasonal 
thermocline near THETA _ 15°C. The latter oxygen maximum was, according 
to the fluorescence measurements connected with the presence of a deep 
chlorophyll maximum in the seasonal thermocline.

 

Figure 9.	Plots of the dissolved oxygen concentration (OXYGEN) versus 
		the pressure (CTDPRS), and the potential temperature 
		(THETA). All the reliable bottle samples with quality flags 2 
		(reliable) or 6 (reliable duplicate) are shown.


 

Figure 10.	Plots of dissolved silica (SILCAT) versus the pressure 
		(CTDPRS), and the potential temperature (THETA). All reliable 
		bottle samples are shown.

The vertical distribution of dissolved silica (SILCAT, Fig. 10)) shows that the 
MSW core is characterized by SILCAT values of about 10 µmol/kg, from 
there slowly increasing downward, and steadily decreasing to the surface 
where values below 1 µmol/kg were observed. Over the continental slope 
this minimum was absent, probably due to increased vertical mixing. At the 
level of the LSW core (2000 dbar, ~3.5°C) a relative SILCAT minimum of 
about 11 µmol/kg was observed. Below this level SILCAT increases 
downward to values of about 45 µmol/kg below 4000 dbar. This is due to the 
relatively large contribution of Antarctic Bottom Water (AABW) to the 
formation of the LDW core. 

The distribution of dissolved nitrite (NITRIT, Fig. 11) shows generally low 
values below 0.05 µmol/kg with the exception of the near surface layer where 
higher values up to 0.5 µmol/kg were found. The plot of NITRIT versus 
THETA indicates that these high values are found in the seasonal 
thermocline near THETA _ 13°C.

 

Figure 11.	Plots of the dissolved nitrite concentration (NITRIT) versus the 
		pressure (CTDPRS), and the potential temperature (THETA). All 
		reliable bottle samples are shown

The vertical distributions of dissolved nitrate (NITRAT) and dissolved 
phosphate (PHSPHT) is given in Figs. 12 and 13. In the surface mixed layer 
with THETA > 15°C NITRAT is nearly zero, while PHSPHT has values of 
about 0.05 µmol/kg. From there downward both NITRAT and PHSPHT 
increase to values of respectively about 17 and 1.05 respectively in the MSW 
core and of 17.5 and 1.1 µmol/kg respectively in the LSW core. Below the 
LSW core the both NITRAT and PHSPHT increase steadily downward to 
values of respectively about 22.5 and 1.5 µmol/kg in the LDW core below 
4000 dbar. 

The values of NITRAT and PHSPHT in the cores of MSW and LSW already 
indicate the N/P Redfield ratio amounts to about 16. This is confirmed in a 
PHSPHT versus NITRAT plot (fig. 14) for NITRAT values between 7 and 
18_µmol/kg. At lower concentrations in the near surface layers there appears 
to be a slight excess of PHSPHT relative to the N/P ratio of 16. Also at the 
higher concentrations as found in the LDW a slight PHSPHT excess is 
observed, probably due to the different N\P ratio in the Southern Ocean, from 
where AABW spreads northward and contributes to the formation of LDW. 
The differing biogeochemistry of SILCAT relative to NITRAT and NITRIT is 
reflected in a much more curved SILCAT versus NITRAT line as shown in the 
second plot in Fig. 14.

		ratio of 16.

The data from the current meters as well as from the ADCP from the 
recovered long term moorings have been analysed in a preliminary way. One 
ADCP and 30 current meters were recovered. Two current meters did not 
hold any data, while in one current meter the digitized direction missed the 
most significant bit. One current meter was stalled for about 10 days because 
of the presence of XBT wire in the impeller rack.. The quality of the current 
meter data turns out to be very good. Both in the low sub-tidal frequencies as 
well as at tidal frequencies large phase differences have been observed over 
relatively short vertical distances (100 to 250 m). The Richardson number is 
estimated to be regularly at or below the critical value of 0.25.  At super-tidal 
frequencies spectral peaks for all kinds of combinations of tidal and inertial 
frequencies have been observed. At the level of the core of the MSW near 
1000 m an eleven months mean velocity of 5 to 6 cm/s was observed over 
the continental slope, directed in an north-westward direction, parallel to the 
continental slope. At the level of the LSW core near 2000 m the currents over 
the continental slope had an eastward component.

The ADCP lander was deployed on the slope of a narrow canyon in the 
continental slope near La Chapelle Bank. Tidal current up to 60 cm/s were 
observed in the lowest 50 m above the bottom, with a considerable shear 
mainly due to a shift of phase of the internal tides. The estimated Richardson 
number was regularly at the critical value for turbulence of 0.25.

At the CTD yo-yo station internal solitons were observed in the seasonal 
pycnocline with a vertical magnitude of about 50 m. The number of solitons 
per tidal period however was smaller than observed in 1995, although in 1996 
the measurements were performed at spring tide, contrary to 1995, when 
similar observations where performed about 5 days before spring tide. Also 
from the instruments of the recovered mooring T1 on the nearby shelf signs 
of solitons were found.

1.5	Major Problems Encountered during the Cruise

No major problems were encountered during the cruise so that all 
observations planned for the cruise could be carried out. The fair weather 
during our four weeks in the Bay of Biscay limited the strain on the 
instrumentation as well as on the personnel.

Occasionally the CTD/rosette system had failures due to malfunctioning of 
the water samplers and the rosette system. The resulting data loss due 
amounted to 8%, mostly caused by problems due to leakage of the G.O. 
rosette system, and due to closing problems with the ill designed NOEX 
samplers. For hydrographic small-volume sampling the simpler and more 
reliable Niskin bottles should be preferred. The problems with the G.O. 
rosette are well known, and hard to solve. But due to lack of systematic 
maintenance of these systems problems have become worse. At the end of 
the cruise the sensor package of the CTD nearly was lost, because the 
stainless steel band used for the fixation of the sensors was torn. This is the 
second time such a failure occurred with the SBE CTD, and it is 
recommended to use other material for fixation of the sensors. The glass tube 
of one of the SIS pressure sensors was found to be broken at station 99. This 
is probably due to a design problem. The manufacturer is aware of this 
problem and is looking for a solution.

During the first two weeks the computer network regularly failed due to bugs 
in the newly installed operating system of the SUN server. After the halfway 
break in Brest "patches" were installed in the server to repair this problem. 
After that major problems with the network did not occur.

Occasionally the level B of the data logging system, responsible for the data 
archiving, broke down, causing data loss for periods of half an hour to about 
10 hours. In the last week of the cruise this system completely failed and was 
replaced by the level B back up system.

Four of the current meters deployed in 1995 and recovered during this cruise 
had internal damage by leaking. On a first inspection no direct cause could be 
discovered, but later on it was found out that the PVC stoppers on empty 
sensor holes had become fragile from ageing, causing leakage through hair 
cracks.

The mooring T1, deployed on the continental shelf preceding the CTD yo-yo 
appeared to be halfway sunk when we came back for recovery. Probably 
leakage of one of the "Floatex" buoyancy elements was the cause of this 
problem. Due to the extra buoyancy of the spar buoy, used as a surface 
marker for the mooring, and which resurfaced during neap tide, the mooring 
could be recovered. With mooring T2 we were not so lucky. When we arrived 
no trace of the mooring could be found. Also during neap tide the spar buoy 
of this mooring did not come to the surface. Thereafter we swept with a 
grappling iron for 7 hours in the vicinity of the mooring location, but did not 
find a trace of the mooring. No cause for the loss of this mooring could be 
established.

At station 27 it appeared that the CTD cable was damaged on the winch drum 
at about 5000 m from the CTD. For safety reasons it was decided to limit the 
amount of cable to be veered out to 4780 m. This prevented us to reach the 
bottom within 200 m for the few remaining deep stations, but hardly interfered 
with the programme.

2	Underway Measurements

2.1 Navigation

RV Pelagia has several different navigational systems. We used the 
Differential GPS receiver for the determination of the position. The data from 
this receiver were recorded every  ten seconds in the ABC data logging 
system. After removal of a few spikes these data were sub-sampled every 
five minutes.

2.2 Echo Sounding

The 3.5 kHz echo sounder as well as the navigational Furuno echo sounder 
were used on board to determine the water depth. The uncorrected depths 
from these echo sounders were recorded in the ABC data logging system. 
Over the steepest parts of the continental slope the depth digitizer of the 3.5 
KC echo sounder was occasionally not able to find a reliable depth. The 
maximum range of the Furuno echo sounder to obtain reliable results was 
about 800 m.

Near the deployment site of the benthic ADCP lander and near the positions 
of the recovered current meter moorings on the continental slope additional 
echo sounder surveys were carried out to determine the topography of the 
deployment locations. Preceding the deployment of the current meter 
moorings a line was surveyed to determine the deployment sites, which were 
bound to predetermined depth ranges.

The SIMRAD EK 500 multiple frequency echo sounder was used to observe 
the variations in the depth of the scattering layer due to internal waves in the 
seasonal thermocline. Whenever the ship was near the continental slope data 
from this instrument were recorded on the ship's computer as well as on a 
colour printer.

2.3 Thermosalinograph Measurements

The Sea Surface Temperature, Salinity, and Oxygen concentration were 
measured with an AQUAFLOW thermosalinograph with a water intake at a 
depth of about 3 m. The primary temperature sensor, mounted near the water 
inlet, had been calibrated just prior to the cruise. For the calibration of the 
salinity sensor, and the oxygen sensor, water samples were taken three times 
per day. With these samples the calibration of the conductivity sensor and the 
oxygen sensor were determined. The observed salinity and oxygen values 
were corrected accordingly. The accuracy of the temperature, salinity and 
oxygen concentration from the thermosalinograph system was estimated to 
amount to 0.01°C, 0.05 and 3 µmol/kg respectively.


3 Hydrographic measurements - Descriptions, Techniques, and Calibrations

3.1	Rosette Sampler and Sampler Bottles

A General Oceanics 24 position rosette sampler was used, fitted with 10 litre 
NOEX sampler bottles. On most stations only 22 sampler bottles were placed 
in the rosette. Their general behaviour was good, but a number of bottles had 
to be replaced during the cruise. This was mainly because of failure of the 
silicon rubber tubes of the closing system causing failures of closing in time. 
The sampling had a resulting failure rate of 8 percent because of 
malfunctioning of the sampler bottles and the rosette system. The samplers 
from which oxygen samples were drawn were mostly fitted with gas tight 
PETP sampler lids. Only at the near surface samplers silicon rubber lids were 
used. Oxygen samples from these bottles were corrected according to the 
algorithm determined during cruise 64PE95N/1, but corrections were small, 
less than 1 µmol/kg.

3.2 Temperature Measurements

On sampler bottles 2, 4, 6, and 8 thermometer racks were mounted, fitted 
with SIS electronic reversing thermometers with a numerical resolution of 
1 mK. On samplers 2 and 8 one SIS sensor was mounted, and on samplers 4 
and 6 three sensors. Also mounted on the CTD was a high precision SBE35 
temperature sensor. This sensor was well calibrated before the cruise, and on 
board zero point checks were performed in a H2O triple point cell. The 
temperatures of the SBE35 sensor were recorded with all samples at 14 deep 
CTD casts. The accuracy of the SBE35 sensor is well below 1 mK.

The standard deviations of the individual readings of the SIS reversing 
thermometers after correction for the systematic offset was estimated from 
the triplicate reading from the SIS sensors mounted on sampler bottles 4 and 
6 to amount to 1.5 mK. The readings from SIS sensors and the SBE35 
sensor were, if necessary, averaged, and are reported in the *.SEA file as 
REVTMP.

The readings from the SBE35 and SIS sensors (REVTMP) were compared 
with the temperature readings from the CTD system when the samplers were 
closed. The CTD temperature (CTDTMP) was corrected for heating due to 
viscous dissipation in the viscous sub-layer around the sensor, and were also 
corrected for  the pressure dependence of the sensor as supplied by the 
manufacturer. The mean difference REVTMP-CTDTMP for all reliable 
samples amounted to 0.2 mK with a standard deviation of 4.4 mK (428 
samples). When using only the samples obtained below 2000 dbar, where 
vertical gradients are small, and connected errors due to differences in 
response time of the different sensors involved are also assumed to be small, 
the standard deviation was reduced to 2.1 mK, while restriction to samples 
obtained below 3000 dbar resulted in a mean difference of -0.1 mK and a 
standard deviation of 1.3 mK (105 samples). Therefore it was decided to 
apply the manufactures calibration of the CTD temperature sensor unaltered. 
The plot of CTDTMP versus REVTMP is given in fig. 15.

		versus the temperature determined with the SIS sensors and 
		the SBE35 sensor (REVTMP). All reliable data points are 
		shown.

3.3	Pressure Measurements

In each of the thermometer racks, mounted on sampler bottles 2 and 8, 2 SIS 
electronic reversing pressure sensors were placed. Before the cruise these 
sensors were calibrated by the manufacturer. A total of 93 reliable pressures 
were obtained. Also readings of the deck pressure was performed with the 
SIS sensors to determine an additional zero offset. Previous experience has 
shown that such offset readings before and after each CTD cast give identical 
results. In our case the application of the zero offset more than halved the 
RMS value of the difference between the pressure readings from the SIS 
sensors and the CTD system. The mean data from the SIS pressure sensors 
have been reported in the *.SEA files as REVPRS.

From comparison of the readings of the pairs of sensors mounted in the same 
thermometer rack it was found that the differences between individual 
sensors had an RMS value of 1.4 dbar.

The readings from the SIS pressure sensors (REVPRS) were compared with 
the pressure reading from the CTD when the samplers were closed 
(CTDTMP). The mean difference REVTMP-CTDTMP was found to have an 
RMS value of 2.1 dbar. Therefore it was decided to apply the manufacturers 
calibration for the pressure sensor unaltered. The plot of CTDPRS versus 
REVPRS is given in Fig. 16.

		pressure (CTDPRS) determined with the SIS sensors 
		(REVPRS). All reliable data points are shown.


3.4	Salinity Measurements

Water was drawn from the samplers into a 0.5 litre glass sample bottle for the 
salinity determination after 3 times rinsing. The sample bottles had a massive 
rubber stopper as well as a screw lid. Salinity of water samples (SALNTY) 
was determined within 36 hours by means of an Guildline Autosal 8400A 
salinometer. Care was taken that the temperature of the sample bottles was 
well adapted to the laboratory temperature. The readings of the salinometer 
were performed by computer, giving the average and statistics of 10 
consecutive readings. For each sample 3 salinity determinations were carried 
out. The standard water used was from batch P119 with a K15 ratio of 
0.99990 (S=34.996), prepared at 28 February 1992.

From most deep CTD/rosette casts two extra duplicate samples were drawn. 
Salinity determinations from the duplicate samples obtained from 
independent salinometer runs were used to determine the reproducibility of 
the salinity determination. The RMS value of the salinity difference between 
the duplicate samples amounted to 0.0008 (115 samples).

The salinity from the water samples (SALNTY) was compared with the salinity 
reading from the CTD (CTDSAL). A persistent difference of 0.0038 was found 
which forced us to alter the manufacturers calibration of the conductivity 
sensor of the CTD system. After applying the new calibration the difference 
SALNTY-CTDSAL for all reliable samples had an RMS value of 0.0016 (503 
samples). When using only the samples taken below 3000 dbar, where 
vertical gradients are small and less prone to cause differences between 
SALNTY and CTDSAL, the RMS value of the difference was reduced to 
0.0011 (74 samples). A plot of CTDSAL versus SALNTY is given in Fig. 17.

		salinity determined from water samples by means of a 
		salinometer (SALNTY). All reliable data obtained at depths 
		below the 25 dbar level are shown.

3.5	Oxygen Measurements

For the oxygen determination water samples were drawn in volume calibrated 
120 ml Pyrex glass bottles. Before drawing the sample each bottle was 
flushed with at least 3 times its volume. When the samples were drawn the 
temperature of the sample was determined. The determination of the 
volumetric dissolved oxygen concentration of water samples was carried out 
by means of a high precision automated oxygen Winkler titration system, 
based on an optical end point determination. The stock solution of KJO3 used 
in the analysis was prepared and calibrated in the laboratory by using 
gravimetric methods. The stock solutions were stored at low temperature 
(~4°C). Final calibration of the 0.2 Mol Na2S2O3 titrant on board took place 
by tritration of at least 6 samples of stock solution samples of 3 different 
concentration levels with the 0.2 Mol titrant. The densimetric oxygen 
concentration was determined by dividing the volumetric concentration by the 
sea water density at sample temperature and salinity and zero pressure.

At each cast duplicate samples were drawn from the deepest an shallowest 
water sampler, and at a number of stations also from an intermediate 
sampler. The difference between the duplicate samples had an RMS value of 
0.20 µmol/kg over the whole cruise (123 samples). This was mainly due to 
inexperience at the beginning of the cruise. From station 33 onwards the 
RMS value of the difference was reduced to 0.15 µmol/kg (102 samples).

For each CTD/rosette cast also 1 to 3 samples were taken for the 
determination of the sea water blank. In the surface layer the mean sea water 
blank amounted to 0.60 (_0.07) µmol/kg, in the sub-surface layer (50 to 
250 dbar) the sea water blanks had a mean value of 0.67 (_0.03) µmol/kg, 
while deeper sea water blanks had a mean value of 0.72 (_0.03) µmol/kg 
These sea water blank values are nearly similar to the values found in the 
previous year. In the reported densimetric oxygen concentrations (OXYGEN) 
these sea water blanks have been subtracted from the determined oxygen 
concentration.

The calibration of the oxygen sensor of the CTD system was determined by 
comparison of the raw dissolved oxygen values from the CTD system 
(CTDOXY), according to the manufacturers calibration, with the OXYGEN 
values from samples taken at the same depth. It appeared that the calibration 
differed from station to station., and also between up-cast and down-cast 
Therefore a separate calibration for each station, and for up-cast and down-
cast separately, was determined with a multiple regression of OXYGEN 
versus the CTDOXY value, and the logarithms of CTDTMP and CTDPRS. 
The raw CTDOXY values for each cast were corrected according to the 
resulting calibration in order to get the final CTDOXY. THE RMS value of the 
resulting differences OXYGEN-CTDOXY for the up-casts and down-casts 
amounted to 2.2 µmol/kg and 1.9 µmol/kg respectively. A plot of CTDOXY 
versus OXYGEN is given in Fig. 18.

CTD system (CTDOXY) versus the dissolved oxygen 
concentration determined from water samples by means of an 
automated Winkler titration. All reliable data are shown.

3.6	Nutrient Measurements

From all sampler bottles samples were drawn for the determination of the 
nutrients silica, nitrite, nitrate and phosphate. The samples were collected in 
polyethylene sample bottles after three times rinsing.  From the deepest 
sampler a duplicate sample was taken at each station, to be analyzed during 
an independent autoanalyzer run in order to determine the precision of the 
nutrient concentrations The samples were stored dark and cool at 4°C. All 
samples were analysed for the nutrients silicate, phosphate, nitrate and nitrite 
within 10 hours with an autoanalyzer based on colorimetry. The lab container 
was equipped with a Technicon TRAACS 800 autoanalyzer. The different 
nutrients were measured colorimetrical as described by Grashoff (1983). The 
samples, taken from the refrigerator, were directly pored in open polyethylene 
vials (6 ml) and put in the auto sampler trays. A maximum of 60 samples in 
each run was analysed. Because of the large differences in nutrient content 
between the upper ocean and the deep water, the analyses were carried out 
in two different calibration ranges. A low concentration range for the samples 
from the upper 1500 m, and a high concentration range for the samples 
collected deeper than 1500 m. Based on the experience gained in 1995 it 
was decided not to filtrate the samples before analysis.

The different nutrients were measured colorimetrical as described by 
Grashoff (1983);

_   Silicate reacts with ammoniummolybdate to a yellow complex, after 
reduction with ascorbic acid the obtained blue silica-molybdenum complex 
was measured at 800nm (oxalic acid was used to prevent formation of the 
blue phosphate-molybdenum).

_   Phosphate reacts with ammoniummolybdate at pH 1.0, and 
potassiumantimonyltartrate was used as an inhibitor. The yellow 
phosphate-molybdenum complex was reduced by ascorbic acid to blue 
and measured at 880nm.

_   Nitrate was mixed with a buffer imidazole at pH 7.5 and reduced by a 
copperized-cadmium coil (efficiency> 98%) to nitrite, and measured as 
nitrite (see nitrite). The reduction-efficiency of the cadmium-column was 
measured in each run.

_   Nitrite was diazotated with sulphanilamide and naftylethylenediamine to 
a pink coloured complex and measured at 550nm.

_   The difference of the last two measurements gave the nitrate content

Standards were prepared by diluting stock solutions of the different nutrients 
in the same nutrient depleted surface ocean water as used for the baseline 
water. The standards were kept dark and cool in the same refrigerator as the 
samples. Standards were prepared fresh every two days. The samples were 
measured from the surface to the bottom to get the smallest possible carry-
over-effects. In every run a mixed nutrient standard containing silicate, 
phosphate and nitrate in a constant and well known ratio, a so-called nutrient-
cocktail, was measured in duplicate. This cocktail is used as a guide to check 
the performance of the analysis, and to allow corrections for the small errors 
in the calibration line. The reduction-efficiency of the cadmium-column in the 
nitrate lane was measured in each run by the use of extra nitrate and nitrite 
standards.

The autoanalyzer determined the volumetric concentration at a standard 
temperature of 20°C. In order to calculate the densimetric concentration in 
µmol/kg the volumetric concentrations were divided by the density of sea 
water at 20°C, sample salinity and zero pressure.

Duplicate measurements carried out on the deepest sample from each cast 
gave RMS values of the differences of 0.28 µmol/kg, 0.02 µmol/kg, 
0.19 µmol/kg, and 0.01 µmol/kg for dissolved silica (SILCAT), nitrite 
(NITRIT), nitrate (NITRAT), and phosphate (PHSPHT) respectively. Possible 
variations in gain factor for the different channels of the autoanalyzer was 
determined by means of the mixed nutrient cocktail. Only for SILCAT and 
NITRAT this gain factor appeared to differ significantly from 1 for a number of 
stations. A gain factor correction for these two parameters was applied to the 
duplicate samples. This resulted in reduced RMS values of the difference 
between the duplicate samples of SILCAT and NITRAT of 0.19 µmol/kg and 
0.14 µmol/kg. Thereupon it was decided to apply the gain factor correction to 
all SILCAT and NITRAT values.



3.7	Fluorescence Measurements

Fluorescence was measured with an AQUATRACKA III fluorimeter adapted 
to measure Chlorophyll A. The excitation wavelength was centred near 
440 nm, with a bandwidth of 80  nm. The fluorescence was measured near 
670 nm with a bandwidth of 30 nm. The instrument was calibrated against a 
chlorophyll solution in acetone. No specific in situ chlorophyll samples were 
taken for the calibration of the instrument. The fluorescence value was 
transformed into an equivalent concentration of chlorophyll dissolved in 
acetone (the parameter FLUOR).


3.8	Transmissometer Measurements

A Sea Tech transmissometer was mounted in the CTD rack next to the CTD 
probe. The instrument had a path length in water of 25 cm. The light 
transmission of a parallel light beam was measured at a wavelength of 
650 nm. No specific in situ suspended matter samples were taken for the 
calibration of the instrument. Since it was known that the calibration of the 
instrument may change from cast to cast, it was decided that in first order the 
existing calibration in air should be used. Thereafter the individual 
transmission profiles were shifted in order to get matching transmission 
values in the deep transmission maximum. This resulted in transmission 
profiles which agreed well with the profiles measured during Pelagia cruise 
PE95N/1 in the Bay of Biscay in the previous year. Note that the transmission 
(the parameter XMISS) depends on the path length which was 25 cm, and is 
expressed as percent values.



3.9	CTD Data Collection and Processing

For the data collection the Seasave software, supplied by SBE, was used. 
The CTD data were recorded with a frequency of 24 data cycles per second. 
After each CTD cast the data were copied to a hard disk of the ship's 
computer network, and a back-up copy was made on another disk. At the end 
of the cruise back up copies were made on tape, and brought to NIOZ, 
together with the hard disk unit, containing all data.

On board the up-cast data files were sub-sampled to produce files with CTD 
data corresponding to each water sample, taken with the rosette sampler. On 
board the down-cast CTD data were processed with the preliminary 
calibration data, and reduced to 1 dbar average ASCII files, in order to allow a 
first analysis, and to be used in the calibration procedure for OXYGEN and 
XMISS on the down-casts.

After determining the calibration of the CTD system, as described above, the 
up-cast CTD data were corrected accordingly. The raw down-cast CTD data 
were processed with the Seasoft software supplied by SBE. Corrections were 
applied for the sampling time difference due to the forced flushing of the 
water along the different sensors, for the heating of the water in the flushing 
system between the temperature sensor and the conductivity sensor, and the 
different response times of the sensors. A time series of mean values of the 
readings was produced for 0.5 s time intervals. This is, given the typical 
veering velocity, equivalent to a pressure interval of about 0.5 dbar. 
Consecutively the parameter values were determined in physical units, using 
the calibration constants, determined as described above. For the CTD casts 
where no water samples were taken for the determination of OXYGEN, no 
calibration constants could be determined for CTDOXY . For these casts the 
CTDOXY values were set at the default value of -9.0 for missing data.

It appeared that the Seasoft software did not remove all spikes in the data 
record, especially in CTDSAL, CTDOXY, and XMISS. In order to remove the 
remaining spikes by applying a median filter over 5 consecutive time bins was 
applied. Hereafter the time series was filtered by means of a low pass filter 
with a width of 5 time bins. Finally the time series was interpolated on 
equidistant 1 dbar intervals, only using the first downward crossing of the 
interpolation pressure by the time series. Since no pressure bin averaging 
was applied, the parameter NUMBER OF OBS. in the *.CTD files was set to 
12, the number of individual data points used to obtain the time series 0.5 s 
averages which were used for the interpolation at equidistant pressure 
intervals.

Oceanographic and Atmospheric Research (GOA), subsidiary of the

ADDENDUM



Search and recovery of mooring BB9

After mooring in the Port of Brest we got a message relayed via NIOZ that the 
ARGOS CLS had monitored mooring BB9 to be at the sea surface. This 
mooring was fitted with an ARGOS emergency  transmitter. After a quick 
conference with NIOZ by telephone, and further discussions at NIOZ, it was 
decided that Pelagia got 48 hours to recover the mooring. At 12:30 local time 
Pelagia left Brest again and reached the position of the last ARGOS fix the 
following morning. At 08:45 the mooring was discovered, and at 09:23 
everything was hauled on board. Then course was set immediately to Brest 
again to minimize the time loss for the following OMEX cruise of R.V. Pelagia.

The cause of the near loss of the BB9 mooring was the unintended release of 
one of the acoustic releases due to leakage. The cause of the leakage is 
unknown yet.

The GOA management group for moored systems did not consider the use of 
emergency transmitters for scientific moorings in GOA programmes. On the 
initiative of ing. S. Ober the NIOZ Department of Physical Oceanography did 
purchase an ARGOS emergency transmitter from the NIOZ budget and fitted 
it on the 75 kHz ADCP which formed the top of mooring BB9. Only due to this 
initiative the release of the mooring was observed, and the mooring could be 
recovered. It is recommended to the GOA management group for moored 
systems to reconsider their policy regarding the use of ARGOS emergency 
transmitters and to apply for a budget to use such a transmitter in every GOA 
mooring.
