| 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. |
