. The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder. Oceanography Bering 54 Physical oceanography running from Unimak Pass to the Pribilof Islands, and an arbitrary line running from the Pribilofs to Nuni- vak Island (Fig. 5-1). The shelf break occurs at an average depth of 170 m (Scholl et al. 1968), and the shelf shoals gradually over a featureless expanse of 500 km. Flow over the continental slope is highly variable (Kinder et al. 1975, Coachman and Charnell 1979, Kinder et al. 1980) with mean flow to the northwest at 5-10 cm/sec.

Oceanography Bering 54 Physical oceanography running from Unimak Pass to the Pribilof Islands, and an arbitrary line running from the Pribilofs to Nuni- vak Island (Fig. 5-1). The shelf break occurs at an average depth of 170 m (Scholl et al. 1968), and the shelf shoals gradually over a featureless expanse of 500 km. Flow over the continental slope is highly variable (Kinder et al. 1975, Coachman and Charnell 1979, Kinder et al. 1980) with mean flow to the northwest at 5-10 cm/sec. The shelf regime is separa- ted from the adjacent oceanic regime by a weak haline front (Kinder and Coachman 1978, Coachman and Charnell 1979). We have found no convincing evidence for exchange of mass or momentum be- tween the shelf and oceanic regimes by eddies or rings. This characteristic is probably the effect of some combination of the width of the shelf, the front overlying the slope, and the weakness of the boun- dary current above the slope. At the same time, a considerable volume of water must flow across this long (~ 1,000 km) shelf break somewhere: about 1 X 10^ m'^ /sec flows northward through the Bering Strait into the Chukchi Sea (Coachman and Aagaard,. 62°- 61°- 60°- 59°- 58° 57°- 56° 55°- 54' St Matthew 1 BERING SEA Figure 5-1. Locations of current-meter moorings. Most moorings had two current meters, one 10 m above bottom and one 20 m below the surface. BC signifies Bristol Bay project and FX signifies Frontal Experiment. Sequential deploy- ments at a mooring site are designated by letter suffixes, , BC-9A. The three moorings southwest of Nunivak Island numbered 1-3 have FX prefixes; all others have BC Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hood, D.
