THE EURYHALINE COPEPOD GENUS EURYTEMORA 



IN FRESH AND BRACKISH WATERS OF THE 



CAPE THOMPSON REGION, CHUKCHI SEA, ALASKA 



By Mildred Stratton Wilson and Jerry C. Tash i 



Collections made in the vicinity of Cape Thompson, AJaska, on the 

 coast of the Chukchi Sea during the course of biological investigations 

 by the Atomic Energy Commission (Project Chariot), have yielded 

 SLX species of the euryhaline copepod genus Eurytemora. These oc- 

 curred in brackish waters (coastal lagoons, pools, and ponds) and in 

 fresh waters (inland lakes, pools, ponds, and pools and ponds near 

 the coast). Collections were made in 1959 by Douglas HiUiard and 

 in 1950-1961 by J, C. Tash. These data partly supplement those of 

 Johnson (1961) who collected from some of the lagoons in 1959. 

 Additional data come from samples from other regions of Alaska 

 accumulated by M. S. Wilson and referred to herein as the Wilson 

 collection. Reports on other copepods and crustacean groups of 

 the Cape Thompson collections are included in papers by Wilson 

 and Tash (MS.) and Hilliard and Tash (1966).
