Atlantic Coastal Fishes --Data Report 1 



Sampling stations were laid out along 14 

 transects situated as normal to the adjacent 

 beach and as parallel to each other as the coast- 

 line configuration would permit (fig. 2). Each 

 transect began at a point as near shore as water 

 depths would allow the Dolphin to enter and ex- 

 tended seaward to the edge of the continental 

 shelf. Lengths of transects varied with the 

 width of the shelf from 20 to 75 nautical miles 

 (37 to 130 km.). The 92 sampling stations were 

 spaced along the 14 transects as follows: 5 miles 

 (9.2 km.) apart inshore, 10 miles (18 .4 km.) 

 apart at intermediate distances from shore, and 

 15 miles (27.8 km.) apart offshore. It was 

 necessary to deviate from this plan in some in- 

 stances to conform with the bathymetry of the 

 continental shelf. 



Dolphin cruises are designated by the 

 initial of the ship and the year, and numbered 

 consecutively during the year; thus, D-66-1 

 was the first cruise of the Dolphin in 1966. 

 Each station is designated by a transect letter 

 followed by a number . Station coordinates are 

 given to the nearest 0.5 miles (0.8 km.) in the 

 accompanying table. Station locations remained 

 unchanged on all cruises except on transect P 

 where they were altered after the first and third 

 cruises to provide more variation in water depth. 



INSTRUMENTS AND COLLECTING GEAR 



Surface water temperatures were 

 measured with stem thermometers accurate to 

 + 0.1° C. (manufacturer's specifications). 

 Vertical temperature profiles were obtained 

 with a mechanical bathythermograph. A strip- 

 chart recorder was installed beginning with 

 cruise D-66-7, to provide a continuous record 

 of surface temperatures . Salinities were 

 measured with a portable salinometer (which 

 also provided supplementary temperature data). 



The Gulf V high-speed plankton sampler 

 (fig. 3) consists of a conical net supported by a 

 stainless steel cylindrical frame with a mouth 

 diameter of 40 cm. (16 in.) and a length of 

 130 cm. (51 in.). Netting is 0.33-mm. (0.013- 

 in.) monel wire, with 30 meshes per inch 

 (ca. 12 meshes/cm.) providing an aperature

size of 0.52 mm. (0.020 in.). A removable 

 stainless steel cup with a flushing window of the 

 same netting is attached to the rear of the net.
