sampler on all but two of the regular and 

 special stations — heavy seas made use of a 

 half -meter silk net advisable on these two 

 stations. Thirty-three runs between sta- 

 tions were accomplished with the Gulf IA 

 high-speed plankton sampler, and 25 runs 

 were obtained with the continuous plankton 

 sampler. Dip-net fishing was carried out at 

 night (under lights) and during the day while 

 on station — results were poor during the 

 entire cruise although conditions for this 

 operation were favorable on many occasions. 

 Trolling with nylon and bone jigs between 

 stations for larger fish was also poor. 



Twelve drift bottles were released 

 for the Woods Hole Oceanographic Institu- 

 tion on each of the inshore stations. The 

 bottles used were 8-ounce, clear glass soda 

 bottles approximately 22 cm. high and 6 cm. 

 in diameter. To reduce wind drift the bot- 

 tles were ballasted with clean dry sand, 

 so as to float vertically at or near the 

 surface. Strangely, there were no returns 

 from these releases. 



This cruise completed a 2-year field 

 study phase of oceanographic and biological 

 conditions along the south Atlantic coast 

 of the United States.

EXPLANATION OF DATA SHEETS AND TABLES 



Oceanographic and Chemical 



Each of the items appearing on the 

 station data pages is explained below. All 

 doubtful data are indicated and were not 

 used in the construction of the curves from 

 which the interpolated values (standard 

 depth values) were derived. Observed values 

 which were obviously false were omitted 

 entirely. A dash in a table means that no 

 value was available. Interpolations for 

 standard depth values for temperature, 

 salinity, sigma-t, and oxygen are IBM calcu- 

 lations; those for the chemical constituents 

 were derived from straight lines between 

 observed values. 



The profiles of salinity, temperature, 

 and density were prepared from these data, 

 and appear as figures 5-17. 



1. Cruise Number . The first cruise over 

 the established station pattern (fig. 1) 

 was numbered Gill 1, and subsequent 

 cruises, Gill 2 through Gill 9 (only 

 Gill 9 is covered by the present report). 



2. Station Number . Stations are numbered 

 consecutively, starting with one, at the 

 beginning of each cruise. The station 

 pattern and numbers as shown in figure 1 

 were maintained on each cruise. If a 

 station or series of stations was not 

 occupied, these station numbers are 

 omitted. Regular stations have numbers 

 only; standard and special stations are 

 specifically indicated. 



3. Date . Month, day, and year are given. 



4. Latitude and Longitude . The position 

 of the station is given in degrees and 

 minutes. 



5. Time . Given in Greenwich Mean Time and 

 is that hour nearest to the start of 

 the first cast. 



6. Depth . Is the observed uncorrected 

 sonic sounding for the station, recorded 

 in meters. 



7. Wind . Wind speed is given in meters per 

 second. Direction from which the wind 

 blows is coded in degrees true to the 

 nearest ten degrees. The last zero is 

 omitted. North is 36 on this scale and
