The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A.

A schematic diagram of the kinds of ice observed along Line B. Arrows mark the coring stations; see also legend for Fig. 12-4. Line C The C-traverse took place on 9 March 1979. On 8 March the weather deteriorated, consisting of blowing snow from the northeast with air temperatures of â 1 to â3 C. On 9 March, the wind was m/sec from the northeast at temperatures between â4 and â5 C. The ice was beginning to rot, and there was a strong southerly swell propagating into the pack. Fig. 12-13 shows the traverse line. Because of the wind, the ice was more open along the line, and the smooth pro- gression from small floes to large floes was not evident as we flew north. Rather, the ice consisted of bands of open water and intermingled large and small floes for the first 30 km, at which point we reached the interior zone. We landed at two stations on the traverse line, C4 and C3. C4 was a large floe consisting of ice which was mushy except in the bottom few centimeters, m thick with a minimum ice temperature of â C. On the floe surface, large amplitude 8 sec waves propa- gated through the ice on which we stood. By con- trast, station C3 was on a large floe immediately adjacent to the rectangular broken ice; Fig. 12-14 shows an aerial view from an altitude of 150 m. This picture shows the swell breaking off rectangular floes about 20 m wide from a much larger floe; again the long axis of the rectangular floes was at right angles to the direction of wave propagation. We landed on the large floe shown in the left foreground of Fig. 12-14 to observe that the ice was firm and m thick, with a minimum ice temperature of â C. Therefore, th
