A.2.	 Cruise Summary Information

a.	 Geographic boundaries:  The cruise occupied stations in the AR16 
area from 40 to 43 N and 9 to 11 W.

The cruise track and station locations are available from the WHPO.

b.	 Stations occupied:  A total of 92 CTD/rosette stations were occupied 
in the AR16 area.

Water sampling on the cruise included measurements of salinity both by CTD 
and water bottle samples, CTD and bottle sample oxygen determination, CTD 
temperature, pH, alkalinity, total carbon (TOC), and nutrients (silicate, 
nitrate, nitrite, phosphate).

c.	 Floats and drifters deployed:   No floats nor drifters were deployed 
on this cruise.

d.	 Moorings deployed or recovered:  Four moorings were deployed in 42 
16'N 10 10'W(a), 42 25'N 10 29'W(b), 41 00'N 9 50'W(c) and 41 00'N 9 35'W(d) 
with 4-5 current meters at 2000, 1200, 800, 300, 100 m deep.
 
After 1 year (a) was recovered, we lost (b) and half of RCM (c) and (d).

A.4.	 Scientific Programme and Methods

The ship departed from Vigo to Station 1, 43º 0.69'N,9º 2945'W, on May 11 
1993. Two CTDs were used. From station 1 to station 37 a Seabird 911 CTD and 
SBE rosette with 24 bottles (1.7 liters) and then from Station 38 to Station 
92 an NBIS Mark III CTD equipped with dissolved oxygen sensor and GO rosette 
sampler (24 bottles, 10 liters) was used. 
The Seabird CTD is uncalibrated (3 years old). The NBIS Mark III was recently 
calibrated (Dec. 92) at the WHOI calibration facility.

Several samples for salinity are taken in all stations and measured in an 
Autosal salinometer using standard seawater (batch P122, 21 Jan. 93) as 
reference. oxygen at all depths sampled was taken and analyzed (Winkler 
method, potentiometric end point).

Samples for pH, alkalinity, TOC, nutrients was taken as usual, and analyzed 
using standard methods (Grashoff, 1984).

A.5.	 Major Problems and Goals Not Achieved

Several problems were encountered with the hydrographic winch but did not 
affect the results of CTD casts.

No problems was presented with the equipment CTD/rosette, which worked well 
all through the cruise. The chemical analysis (salinity, oxygen, nutrients) 
were done on board without problems.

A.6.	 Other Incidents of Note

None noted.
