4. Tracer trajectories from the western shelf of South Georgia: ship displacement data

   Abstract:  Corrected ships heading data were used to calculate drift data for the shelf area to ... the west of South Georgia. The data were collected over a six-week period during 1986. A distance ... weighted interpolation was used to obtain tracer trajectories in this irregular data grid. The vector field ... is complex with no simple flow field.
