The Eastern Bering Sea Shelf The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder easternberingsea00hood Year: 1981 Benthic invertebrate macro fauna 1085 indicating a strong relationship between sediment and fauna. Group VII, divided in distribution between an enclave north of St. Lawrence Island and another north of the Pribilof Islands, appears likewise to be governed by sediment type. While the depths of these two enclaves are significantly different (means of 35 and 69 m), the mean sediment particle-sizes are quite similar ( and phi). Group III, another group with split distribution, occurs only within Anadyr Strait and Bering Strait and is probably controlled by current structure and bottom type. Group VIII, the Central Bering Supergroup, has distributions in both the Bering and Chukchi seas and possesses considerable faunal and environmental complexity. In general, the major correlative element of all these cluster groups seems to be sediment type, although often this factor may in itself reflect other variables such as current regime. Several of these cluster groups correspond closely to the distribution of Bering Sea water masses (Fig. 62-5) as defined by Takenouti and Ohtani (1974). Almost always when a cluster group has split areal distributions, the standing-stock biomass of the more northern distribution appears to be higher than that of the southern, supporting the hypothesis of south to north increase in standing stock over the study area. Unfortunately, the variability of standing stock within groups is such that this trend can be supported at the 95-percent confidence level only for Cluster Group VI. This observed tendency for station groups and faunal assemblages to be repeated in the Bering and Figure 62-5.
