Strongylocentrotus made up and percent of the biomass at deep-water stations in the Chukchi Sea and northern Bering Sea, respectively (Tables 65-3 and 65-4; Figs. 65-29 to 65-31). The greatest concentration of these sea urchins came from a station immediately north of the Bering Strait; the biomass was g/m^, and the abundance was 1,267 urchins/km. Basket star Gorgonocephalus caryi Gorgonocephalus caryi was found in the south- eastern Bering Sea in waters deeper than 40 m, but was more abundant at depths >100m. It made up percent of the biomass of the latter depth stratum. In the northern portion of the Bering Sea and in the southeastern Chukchi Sea it accounted for and percent of the biomass at >40-100m, respectively. The mean density at >40-100 m in the northeastern Bering Sea was The 0-40 m depth in the southeastern Bering Sea was the only stratum where this basket star did not occur; it accounted for less than 3 percent of the biomass at all depths in the southeastern Bering Sea (Tables 65-3 and 65-4; Figs. 65-32 to 65-34). A station immediately south of the Bering Strait contained the greatest quantity of G. caryi, g/m^ and 562 Tunicate Styela rustica macrenteron Styela was found in all three study areas but was most common in the southastern Bering Sea at >40-100-m stations, where it made up percent of the biomass and had a mean density of km. Styela accounted for less than 1 percent of the biomass in the northeastern Bering Sea and percent of that of the Chukchi Sea (Tables 65-3 and 65-4; Figs. 65-35 to 65-37). The greatest catch of Styela came from a station with a depth of 68 m in the southeastern Bering Sea (57°'N, 168°'W); here the biomas
