The oceanographic wot1k was done by a three-man group with assistance from tihe visiting iArgentine scientist. It was a continuation of the successful cooperation with USA and Argentina under the IWSOE Programme. Over 100 CTD-soundings of salinity, temperature and depth were done using a Neil Brown CTD·sonde. Tthe deepest oí these soundings were done to 3,000 m, and at water depths of 1,000 m or less they were usually ta'ken to tihe sea bed, which revealed hitherto unsuspected phenomena in the lower tens of meter of the water column. Ten Aanderaa current meters, that will record tero– perature, currents, and salinity, were placed near the sea bed in the central part of the Weddell Sea. Half of the roeters were supplied by the USA, and they will all record data every ihour for one year.
