The Eastern Bering Sea Shelf The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder . easternberings00hood Year: 1981 Water transport in the vicinity of Bering Strait 99 three months of deployment was highly variable in direction, generally alternating between periods with northerly and southerly flow components. Peak speeds were typically 15-20 cm/sec and the vari- ability time scale in the range of 3-10 days. In early December the speeds decreased to a slower level, typically 10 cm/sec or less, but much more nearly uniform in direction, generally NNW. The record from NC7 is quite different. The flow there was considerably faster, commonly exceeding 20 cm/sec and not infrequently twice that or more. The first one-fourth of the record shows relatively few southerly flow events, but from late October on such events dominate much of the record. The time scale of these events is rather uneven. On the one hand, from early November to early December there was a remarkably regular pattern to the flow rever- sals, with a northerly set for two to three days followed by a southerly one for a like time. On the other hand, there were times of prolonged southerly flow, the most conspicuous beginning in mid- December and persisting for 23 days. Other flow reversal sequences are intermediate to these extremes. During the last month of the record (March) the speeds were decidedly lower, but the directional reversals continued. Figures 7-3 to 7-9 show the temporal development of the current cross section month by month. The vertical axis is the time in days, and the six moorings are placed in their relative positions along the hori- zontal axis. The isotachs represent the vector daily mean flow component normal to the current-meter section (cf. Table 7-3 below). The hatched areas represent incidents of reversed flow, , nominally southward.
