The general cyclonic circulation over the deep basins, the strong southward flow adjacent to the western boundary (East Kamchatka Current), and the northwestward flow paralleling the shelf break (Bering Slope Current), are well founded. Observations and modeling indicate that bottom features such as Shirshov and Bowers ridges influence flow, and that the small gyres suggested here are probably transient eddies. Considering the evidence then available, they prudently left the shelf blank (arrows could have been safely added in the Bering Strait). on the spatial and temporal variability (, devia- tions from mean conditions). Sayles et al. (1979) used volumetric analysis to examine the annual cycle of water mass properties over the deep basin. Assessing seasonal changes in temperature and salinity against the background of mean conditions, they produced an atlas of water mass properties in the upper 1,500 m of the basin. This atlas, focused on the deep basin and on annual periods, is the culmination of earlier work directed at large spatial scales and long temporal scales. There have been two efforts to model the Bering Sea circulation using wind stress and inflow condi- tions as forcing. Bacon (1973) used a barotropic model of the deep basin with 56-km grid spacing, and Han and Gait (1978) used a similar model covering both deep basin and shelf with 100-km grid spacing. The results of both models over the deep basin were reasonable—a general cyclonic circulation modified by large bathymetric features, and modulated by the annual cycle of wind stress. Over the shelf the Han and Gait model showed flow toward Bering Strait concentrated on the western side of the shelf, in accord with present views. These models are not fully reali
