 north-east coast again inside the main Weddell current. The Bellingshausen Sea water

and a mixture of it can be distinguished from the Weddell Sea water by its slightly 

 higher temperature and lesser salinity. The other part of the Bellingshausen Sea water 

 approaching from the north-west forms a second area of mixture with the Weddell Sea 

 water off the north-east coast. Beyond all this local disturbance and mixing over the 

 continental shelf the two currents apparently continue their flow to the north-east to be 

 bent round to the east under the influence of the west wind drift. Some Weddell Sea 

 water may also approach South Georgia from the south-west, as shown in the dotted 

 arrows in the figure. Figs. 4 and 6 should be compared with the contour maps in 

 Figs. 1 and 2. The whaling grounds of South Georgia are situated over the submarine 

 plateau on which South Georgia stands, and which sets up this complex system of
