given by Scripps Institution of Oceanography 

 and Fish and Wildlife Service (1952). The sta- 

 tions occupied during the eight cruises are shown 

 in figures 2A and 2B. 



The station data for the cruises are given in 

 table 1. An asterisk in the table indicates an ap- 

 proximate value. The stations are listed in in- 

 creasing numerical order by line from north to 

 south and by station number from east to west. 

 When the same station was occupied more than 

 once during a cruise, the earliest occupancy was 

 designated "a", the next "b", . . . The depth 

 fished was determined or estimated in a variety of 

 ways. A depth telemeter with a conducting cable 

 was used for some stations on cruise C6208; the 

 Brown Depth Recorder for several stations on 

 cruises H6105 and H6204; and a bathykymograph 

 for a few stations on cruises B6203, B6204, B6212, 

 and B6303. For some stations on cruise H6204, 

 a factor of 0.37 times the length of the wire out, 

 was used to estimate the depth fished. 



The depth of bottom at each station, the amount 

 of wire out, and the depth fished are recorded in 

 meters. This has produced some, uneven or ir- 



regular numbers that are frequently repeated in 

 table 1. One reason for this is that depth of bot- 

 tom at each station was originally recorded in 

 fathoms, either from the depth recorder or chart 

 reading, and was subsequently converted to meters 

 to conform to the required style of this report. At 

 a number of stations on some of the cruises, the 

 amount of wire out was set at a particular number 

 of meters, and the calculated or estimated fishing 

 depth was a reflection of amount of wire out (for 

 example, on cruise H6204 most stations were made 

 with either 800 or 4,500 m. of wire out, and the 

 estimated depth of fishing was 298 and 1,676 m., 

 respectively). 



The types of tows are listed as horizontal or 

 oblique. For horizontal tows, a selected amount 

 of wire was let out and the trawl was towed within 

 a generally restricted dearth range. Obviously, 

 the trawl was fishing in descent to and ascent from 

 this depth, but most of the fishing effort for a 

 horizontal tow was usually near the maximum 

 depth fished. It is recognized that after the 

 selected amount of wire has been let out, the trawl 

 may sink for a time while being towed. Also, if
