Oceanographic Features of the East and South-East Indian Ocean for June 1983

摘要

During the period late May to late June 1983 two research vessels and seven ships of opportunity transited sections of the south-east and east Indian Ocean. Expendable bathy thermographs were deployed and several Nansen stations occupied, providing a rare occasion of wide-spread quasisynoptic data coverage for the area. Satellite imagery is available from two sources and three satellite tracked drifting buoys were in the area. Data are used to form a broad scale description of oceanographic conditions for the period, with more detailed analysis possible in the area north-west of Australia. Comparisons are made with data from the Indian Ocean Expedition of early 1960s and other sources. The relation of surface thermal patterns to circulation is examined.
