The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder easternberings00hood Year: 1981 8 Physical oceanography Figure 1-3. Mean surface salinity for summer (g/kg, taken from Favorite et al. 1976). This pattern not only conforms to the general circulation over the deep basins, but suggests the front overlying the slope. The mean horizontal salinity gradient, v^rhich is essentially congruent with the horizontal density gradient, is an important driving force for flow^ over the slope and over parts of the shelf. The focus of research is now shifting from such long-term and broad-scale distributions as shown here (and in Fig. 1-2), toward departures from the mean at many temporal and spatial scales. Research topics include climatic variability, tidal patterns, mesoscale eddies, fronts, and finestructure. Note that the intervals between isohalines are not uniform. out). Over the shelf important features such as tidal flow, fronts, and stratification are not included in the larger area model. Over the deep basin these models are incapable of resolving the ubiquitous mesoscale (about 50-100 km diameter) eddies found there. Modeling promises to increase our understanding in the future, but this promise is not yet fulfilled. Recent observational work in the deep basin has concentrated on eddies (, spatial variability) with scales of 10-100 km. Kinder et al. (1975) surveyed the Bering Slope Current (Arsenev's 1967 Transverse Current). While it flowed northwestward parallel to the shelf break, a series of eddies about 100 km in diameter were embedded in the current. Kinder and Coachman (1977) found a similar-sized eddy in outer Pribilof Canyon, but inferred that its generating mechanism differed from those seen earlier. Kinder et al. (1980) detected an eddy in the southeastern corner of the Aleutian Basin by using drogued drifters tracked by satellite and measured the eddy by hydro- graphic survey. A second survey of th
