Record #112515:

An Antarctic field study of the rheology and movement of a sea-ice floe aggregate / T.H. Jacka, R. Thwaites, J.C. Wilson.

Title: An Antarctic field study of the rheology and movement of a sea-ice floe aggregate / T.H. Jacka, R. Thwaites, J.C. Wilson.
Author(s): Jacka, T. H.
Thwaites, R.
Wilson, J. C.
Date: 1991.
In: Annals of Glaciology. (1991.), Vol. 15 (1991)
Abstract: Strain grid was established around M.V. Nella Dan, which became beset in ice in October 1985 at 66° S, 51° E, about 40 km from coast. Measurements over 11-d period suggested that ice field was weakly divergent, opening by 3.4% during this time, but there is doubt about reliability of measurements. Drift speed and direction were found to be highly dependent on wind speed and direction, drift rate being 2.7% of wind speed at angle of 29° to left of wind direction. This suggests that, in this area, floe aggregate was in free drift.
