1.2. CRUISE SUMMARY INFORMATION

SUMMARY

Early before noon of 26 September RV Pelagia left the quay in the NIOZ 
harbour at Texel, and headed for the Irish continental shelf. Underway 
hauls with the plankton net at four stations were performed. The 
hydrographic programme with stations along the former WOCE line 
A1E/AR7E started early in the evening of 30 September. Due to too 
strong winds and high waves three times the survey was interrupted. 
This caused the skipping of four planned stations. Station 43 at the 
end of the section over the Greenland continental shelf was occupied in 
the afternoon of 10 October. From there course was set to the western 
slope of the Mid Atlantic Ridge to carry out measurements at two 
hydrographic stations which were skipped before due to bad weather. 
After finishing these stations course was set to the home port of RV 
Pelagia at Texel. At part of the hydrographic stations covering a range 
of North Atlantic hydrographic regimes plankton net casts were carried 
out. During the homeward bound part of the cruise additional net casts 
were performed over the continental shelf. A summary of the 
hydrographic and plankton net stations is given in the appendix. During 
the whole survey the Vessel Mounted ADCP (VMADCP) was switched on. Sea 
surface temperature, salinity, echo sounder depth, meteorological 
parameters and navigation information were recorded continuously.

CRUISE TRACK

The cruise was carried out in the North Atlantic Ocean. The cruise 
track is shown in figure 1.

NUMBER OF HYDROGRAPHIC STATIONS

A total of 41 CTD casts was recorded on the research line. On 39 of 
these casts, water samples were taken for the determination of salinity 
and dissolved bio-geochemical components. Three water samplers in the 
rosette system were fitted with reversing electronic pressure sensors. 
The positions of the hydrographic stations are indicated in figure 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 (10 m).

HYDROGRAPHIC SAMPLING

During the up-cast of each CTD/rosette station water up to 24 samples 
were taken at regular depth intervals. The samples were analysed for 
salinity, oxygen and nutrients. For test purposes also Dissolved 
Inorganic Carbon (DIC) was determined from the samples collected on the 
hydrographic section. The vertical distribution of the sampling 
locations is indicated in figure 3.

NUMBER OF PLANKTON NET CASTS

At 23 positions along the hydrographic section and during outward and 
homeward transit one or more plankton net casts were performed. 
Vertical hauls were taken using a plankton net with a diameter of 1 
meter and a mesh size of 500 mm. Sampling depth varied between 300 and 
24 meters, depending on the depth of the station and the density of the 
plankton. The net was hauled at a speed of 15 to 20 m/min. When back on 
board he catch was carefully washed into a bucket with a gentle flow of 
sea water. The organisms in this sample were then concentrated by 
pouring the content of the bucket through a sieve.

1.4. SCIENTIFIC PROGRAMMER AND METHODS

The goal of the research carried out during the cruise was to establish 
the hydrography along a zonal section between Ireland and Greenland. 
This section is the former A1E/AR7E section of the WOCE Hydrographic 
Programme, which has been surveyed annually since 1990. The re-survey 
of this section is carried out in order to determine climate related 
inter-annual changes of the hydrographic structure in the North 
Atlantic Ocean. This survey is carried out in co-ordination with Dr. K. 
P. Koltermann (BSH, Hamburg) who is in charge of similar surveys along 
sections located further to the south.

The CTD-rosette frame was fitted with weights 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 10 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 reversing electronic pressure sensors were recorded. 
The CTD frame was also fitted with an LADCP which measures velocity 
profiles.

As an additional programme biological sampling was carried out with a 
plankton net. The plankton samples will be used for the study of the 
genetic population structure of chaetognaths. The plankton net was 
lowered to depths of 24 to 300 m.

PRELIMINARY RESULTS

At the end of the cruise the data are available in raw form and in 
partially processed form, but without final calibration applied. Oxygen 
and nutrients are still in volumetric concentrations and should be 
transformed into densimetric concentrations and corrected for sea water 
blanks and standards. However already from the partially processed 
data, presented in figures 5 to 10, some insight can be gained of the
hydrographic situation along the hydrographic section.


1.5. MAJOR PROBLEMS ENCOUNTERED DURING THE CRUISE

Especially in the early stages of the survey many sampler bottles did 
not close satisfactorily because the thickness of the O-rings in the 
sampler lids were not according to specifications. Intense servicing 
and selecting O-rings from the spare parts for accurate size solved 
most of these problems. Ultimately 7% of the samples had to be rejected 
because of sampler failure. It is recommended that for future cruises 
enough quality controlled spare O-rings are available, preferentially 
rings made of a softer type of rubber.

Temperature control in laboratory container 1 initially caused 
problems. Since for the use of the salinometer a tight temperature 
range in the laboratory is required, this malfunction hindered the 
progress of the salinity determinations. Only after establishing 
contact with the department of marine technology at NIOZ the problems 
could be overcome. It is recommended that in future cases where 
container 1 is used the technical staff on board RV Pelagia is informed 
ahead of the required settings of the air-conditioning.

In the auto-analyzer laboratory containers the air conditioned 
functioned well. However the direct flow of cool air along the auto-
analyzers caused unstable measuring conditions. It is recommended to 
study how the air flow along the instrumentation can be controlled by 
means of adapting the position of the air inlet and the blower of the 
air-conditioning.

It appeared during the cruise that both the oxygen sensor and the 
fluorimeter of the Aquaflow thermosalinograph system malfunctioned. It 
should be considered to replace these sensors on short term.

2. UNDERWAY MEASUREMENTS

2.1. NAVIGATION

A differential GPS receiver was used for the determination of the 
position. The data from the receiver were recorded every ten seconds in 
the underway data logging system. After removal of a few spikes and 
application of a 5 min. running mean these data were sub-sampled every 
five minutes.


2.2. ECHO SOUNDING

The 3.5 kHz echo sounder was used on board to determine the water 
depth. The uncorrected depths from this echo sounder were recorded in 
the underway data logging system. In rough seas the depth digitizer of 
the echo sounder was occasionally not able to find a reliable depth.


2.3. THERMO-SALINOGRAPH MEASUREMENTS

The Sea Surface Temperature, Salinity, and dissolved Oxygen 
concentration were measured continuously with an AQUAFLOW thermo-
salinograph with the water intake at a depth of about 3 m. For the 
calibration of the salinity sensor, water samples were taken one to 
three times per day.


2.4. METEOROLOGICAL DATA

Air temperature and humidity, relative wind velocity and direction as 
well as air pressure were measured and recorded by the underway logging 
system. 



3. HYDROGRAPHIC MEASUREMENTS - DESCRIPTIONS, TECHNIQUES, AND CALIBRATIONS

3.1. ROSETTE SAMPLER AND SAMPLER BOTTLES

A 24 position rosette sampler was used, fitted with 5 and 10 litre NOEX 
sampler bottles. A multi-valve system, developed at NIOZ, allowed 
closing the sampler bottles by computer command from the CTD operator. 
The general behaviour of the samplers was good, although repeated 
failure of a single sampler occurred. Such samples are identified to be 
suspect because of sampler failure. As soon as such failure was 
reported the sampler was serviced in order to overcome the problem.


3.2. TEMPERATURE MEASUREMENTS 
     (S. Ober)

Mounted on the CTD-rack was a high precision SBE35 reference 
temperature sensor, which recorded the temperature every time a sampler 
was closed. The data, obtained with this sensor are used to control, 
and if necessary to correct the calibration of the CTD temperature 
sensor. The final calibration of the temperature sensor S/N 2211 was 
completed before the end of the cruise.


3.3. PRESSURE MEASUREMENTS 
     (S. Ober)

On sampler bottles 4, 11, and 16 thermometer racks were mounted, fitted 
with SIS reversing electronic pressure sensors. On deck, prior to the 
CTD cast, these pressure sensors corrected internally for zero 
pressure. The readings of these sensors are used to control, and if 
necessary to correct the calibration of the CTD pressure sensor. The 
final calibration of the pressure sensor SBE-247 was completed before 
the end of the cruise. No further corrections of the calibration are 
required.


3.4. SALINITY MEASUREMENTS 
     (M. Hiehle)

Water was drawn from the samplers into a 0.25 litre glass sample bottle 
for the salinity determination after 3 times rinsing. The sample 
bottles had a stopper as well as a screw lid. The salinity of water 
samples (SALNTY) was determined by means of an Guildline Autosal 8400B 
salinometer. The salinometer was installed in a laboratory container, 
fitted with an air conditioning system. This kept the surrounding air 
temperature constant within 1°C. Initially the salinometer suffered 
from electro-magnetically induced instability, but these problems were 
at least partially overcome. The source of the problems could not be 
located. Homeward bound we were able to complete the salinity 
measurements. The final calibration of the conductivity sensor, based 
on these samples, was completed before the end of the cruise.

From some deep CTD/rosette casts an extra duplicate sample was drawn. 
Salinity determinations from the duplicate samples obtained from 
independent runs are used to determine the reproducibility of the 
salinity determination.


3.5. OXYGEN MEASUREMENTS 
     (D. Volkov)

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 spectro-photometer technique, 
recently developed at NIOZ. Before and after the cruise the spectro-
photometer will be inter-calibrated with a automatic end point 
determination Winkler method. It appeared that the software used to 
calculate the oxygen concentration from the measurements contained a 
flaw. The final calculations will be done at NIOZ.

At each cast where samples for the oxygen determination were drawn, 
duplicate samples were drawn from the deepest water sampler in order to 
determine the precision of the analysis.


3.6. NUTRIENT AND TIC MEASUREMENTS 
     (K. Bakker)

From all sampler bottles samples were drawn for the determination of 
the nutrients silica, nitrite, nitrate and phosphate as well as TIC. 
The samples were collected in polyethylene sample bottles after three 
times rinsing. The samples were stored dark and cool at 4°C.


NUTRIENTS

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 poured into open polyethylene vials (6 ml) and put in the 
auto sampler-trays. A maximum of 60 samples in each run was analysed. 
The samples were not filtered 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. Each run of the system had a correlation coefficient for the 
standards off at least 0.9998. 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. The reduction-efficiency of 
the cadmium-column in the nitrate lane was measured in each run.


TIC

Total inorganic Carbon (TIC) was measured with a Technicon Traacs 800 
rapid flow auto-analyzer. The sample rate was set at 45 samples per 
hour, measuring all the CTD-Rosette samples, approx. 800 samples in 
total. All measurements were calibrated with a stock solution of 
Sodiumcarbonate diluted to Dicksonseawater containing a well-known 
concentration of TIC. The method used is still in a test case and has 
to be improved to work proper on ships.

On a manifold the continuos sample or wash stream is acidified (pH 
below 1) before flowing over a dialyser. The dialyser contains a 
silicon membrane, separating the acidified sample-stream and the 
slightly alkaline coloured detection stream. In the sample stream the 
TIC is transferred to CO2 and forced by the low pH to the other side of 
the membrane in the slightly alkaline stream. This alkaline detection 
stream is coloured purple with Phenolphtaleine, by reaction with CO2 
the pH drops and the solution will be de-coloured depending on the 
concentration of CO2 passing the membrane. This absorbing of CO2 is a 
kind of titration resulting in 2nd order calibration curves. The colour 
is measured in a flow-cell at 550nm. Due to obtain better statistical 
values the method is chemically tuned for the field range from 2000 to 
2300 mM.

The calibration standards were prepared fresh daily by diluting the TIC 
stock (200mM) using electronic pipettes with high reproducibility, into 
four calibrated volumetric flasks. The seawater used for diluting is 
the TIC standard seawater prepared by Dickson. Overall temperature to 
calculate from mmol/dm3 to mmol/kg was 22°C. As a reference, aged 
seawater was poisoned with Mercurychloride to make it "biology stable" 
and during the cruise being bottled for coulometric titration at home 
to check for any drifts. 


3.7. CTD DATA COLLECTION AND PROCESSING 
     (R.X. de Koster, S. Ober)

For the data collection the Seasave software, produced 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 daily back-up copy was made on tape.

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. The CTD data were processed with the preliminary calibration
data, and reduced to 0.5 s average ASCII files, which were used for the 
preliminary analysis of the data. Full data processing with the final 
calibration values will be completed at NIOZ, Texel.


3.8. LADCP DATA COLLECTION AND PROCESSING 
     (M.T.J. Hillebrand)

Current velocity and direction data from the entire water column were 
measured with two synchronized self-contained 300 kHz ADCP's mounted on 
the CTD frame. One of the two is downward looking, the other one 
upward-looking. Data collection takes place during the up and down cast 
of the CTD. The data are subsequently stored in solid state memory.

The LDACP data collections was started a few minutes before the 
deployments of the CTD and was stopped immediately after the CTD was 
back on deck. Then the data were transferred from the internal solid 
state memory to the dedicated service computers, and subsequently 
copied in the appropriate directory on the ships computer network.

A MATLAB master script file developed by Martin Visbeck, LDEO, version 
4.0 Jan. 2000, has been used for data processing, data reduction and 
calculations of the current velocity and direction profiles. The master
script file refers to several other sub-script files. Each of these 
sub-script files has a specific task controlled by the master script. 
Essential in the calculations are the correct input of start and stop 
times and start and stop positions of the CTD. The MATLAB programme 
plots the results of the measurements and calculations as well as 
several quality parameters. The content of the master script and the 
results of the water profile and bottom track calculations are also 
stored in three separate ASCII files.

Malfunctioning of one of the ADCP's during a CTD cast, even for a short 
period is the cause of unreliable and wrong velocity/direction 
profiles. In such a case a manual inspection of the data with the RDI 
programme BBlist provides adapted start/stop times. One of the problems 
that occurred was to find the corresponding times and positions in the 
CTD file. The problem was tackled by Ronald de Koster through the 
Development of a programme that is able to search the CTD file for the 
desired times and generates corresponding positions and depth as 
output.


3.9. VMADCP DATA COLLECTION AND PROCESSING 
     (S. Ober)

The VMADCP data were collected with a dedicated service computer, 
together with the appropriate navigational data and the data from the 
pitch and roll sensor. Daily these data were transferred to the 
appropriate directory of the ships computer network. Data processing 
will take place at NIOZ after the cruise. Effort was spent during the 
cruise on improving and extending quality control and de-spiking of the 
stored navigational data in the VMADCP files.


3.10. PLANKTON NET PROCESSING 
      (K. Peijnenburg, E. van Haastrecht)

Speciation in the marine environment is generally thought to be slow. 
However, genetic population structure (the blueprint for speciation) of 
marine organisms is not well understood. The aim of this project is to 
gain more insight into the population structure of planktonic 
organisms, in particular of chaetognaths. Chaetognaths are 
hermaphroditic carnivorous planktonic organisms, which feed mainly on 
copepods. Particularly we are interested to compare the genetic 
structure of two species of chaetognaths, SAGITTA SETOSA and S. 
ELEGANS. S. SETOSA has a disjunct distribution occurring in coastal 
areas of the North Sea, Mediterranean and Black Sea. S. ELEGANS has a 
circum-Antarctic distribution, occurring in the North Atlantic and 
North Pacific.

SAGITTA SETOSA was found in the North Sea, English Channel, Celtic Sea 
and Irish Sea (as expected). S.ELEGANS was found in the Celtic Sea and 
the Irish Sea, but was not present in any of the North Atlantic 
samples. In the NorthEast Atlantic, at the start of the transect, S. 
SERRATODENTATA was present. In the western part of the section, 
especially in the Irminger Sea, we found EUKROHNIA HAMATA and SAGITTA 
MAXIMA. S. LYRA was found on two occasions along the section. Live and 
intact specimens were preserved individually in lysis buffer for future 
DNA-analyses in the lab. Damaged, parasitized or unidentified 
individuals were preserved in formalin (4%) for morphological studies. 
From most stations a complete plankton sample has been preserved in 
formalin.


3.11. DATA MANAGEMENT 
      (R.X. de Koster, J. Derksen, M. Hiehle)

All raw data were copied to a cruise directory on the network computer 
in different groups of subdirectories. Subsequent processed data, final 
products, documents and figures were copied to separate subdirectories 
within the cruise directory. Daily back ups were made on magnetic tape. 
At the end of the cruise copies of the whole cruise directory have been 
made on CD-ROM. By help of a range of measurement forms all data were 
tracked. A final overview of the hydrographic stations, water samples, 
and the available raw date was made in a cruise summary file and a 
water sample file.

CCHDO DATA PROCESSING NOTES

Date        Contact       Data Type    Event
----------  ------------  -----------  ---------------------------------------
2008-04-14  van Aken      CTD/BTL/SUM  Submitted; also PDF cruise report
            A few weeks ago I did submit the hydrographic data of the former 
            AR7E section from the year 2000.  Please inform me whether they 
            were reaceived and readable for you. If So I will submit more data
            from this section.

2008-04-22  Key           BTL          Assigned Qual flags
            1. I QC'ed all the bottle values (only a very few set to 3, notes 
               at end)
            2. For the bottle flag (bf), I set to 2 except in those cases where
               there were no bottle values. When no bottle values I set the bottle
               flag to 9
            3. I generated a CTDSAL flag (all set to 2), but did not QC the
               ctdsal assuming Dave or someone better trained in CTDSAL would be
               better suited to this task.
