PurposeResearch
ObjectivesGeophysics/ Geology
A wide variety of studies were planned for separate regions of the Southern Ocean:
1) Measure heatflow in some of the small basins in the Scotia Sea to determine their ages
2) Recover an array of previously deployed current meters
3) A survey of an area of the Scotia Ridge between South Georgia and the Falklands
4) Extend the knowledge of a region to the west of the Antarctic Peninsula by the implementation of coring and seismic programmes. This work occupied the whole of Leg 3.
