Sea ice drift near Bering Strait during 1982

Abstract: Six Argos ice stations were deployed in the northeastern Bering Sea in January and February 1982. Four moved north through Bering Strait and made between one and five passes through the strait before they sank or were crushed by the ice, and two remained in western Norton Sound and Shpanberg Strait. Net winds in the region were directed toward the southwest and were relatively uniform geographically. Net currents were northward, and both mean velocity and mean speed were greater at Bering Strait than at Shpanb… Show more

“…A drift angle of 37 ø was found by Thorndike and Colony [ 1982] for winter/spring conditions, and the 3% drift has been observed at several locations in the Arctic [e.g., Thorndike and Colony, 1982;Pease and Salo, 1987]. The polynya width, W, is a balance between advection and production of ice as dW PW --=ui---, (2) dt h i where P is the (area-averaged) ice production, hi is the effective collection thickness of frazil ice deposited at the ice edge (further discussed below), and u, is the ice velocity normal to the coast taken to be positive in the offshore direction.…”

“…Frazil formed in the polynyas is advected southward, eventually consolidating into a solid ice sheet within a few tens of kilometers of land. This ice is driven southward at rates as high as 3% of the wind speed [Pease and Salo, 1987;Pease and Overland, 1984]. As the process continues, ice is constantly generated in the polynyas and distributed downwind.…”

“…For winds with an alongshore component the angle between the wind and ice drift will be less than the free drift angle. These predictions are confirreed for Alaskan shelves away from Bering Strait with an average ice/10-m wind speed ratio of 3.8% and drift angle of 21% for a January-February 1982 data set [Pease and Salo, 1987]. Pease and Salo [1987] also show a residual for a free drift force balance that is the same magnitude as the wind and current stress, which they attribute to coastal setup and internal ice stress.…”

“…Sea ice motion and concentration are influenced by the presence of coastlines (Figure 1). For example, wind-driven ice drift is coupled to changes in sea level and resulting coastal currents [Ikeda, 1985;Pease and Salo, 1987-]. The presence of coastlines contributes to large divergence and shear rates in the sea ice motion field, of the order of 12% per day compared to central Arctic rates of < 1% per day [Hibler et al, 1974].…”
