RRS Discovery cruise 201 was a UK contribution to the World Ocean Circulation Experiment (WOCE), Core Project 2, the Southern Ocean. One section was worked across the Agulhas Basin and the Crozet Plateau, and three sections were worked across the Polar Front. A total of 97 CTD/rosette stations were made with analysis for salinity, dissolved oxygen, nitrate-nitrite, phosphate and silicate. Samples for the freons CFC-11, CFC-12 and CFC-113 were taken approximately every other station and for oxygen isotope analysis every third station. Other measurements included currents of the upper few hundred metres with an Acoustic Doppler Current Profiler, meteorological parameters, and sea surface temperature and salinity. XBT drops were made in addition to CTD casts. Eight moorings were laid across the Agulhas basin and Crozet Plateau. These are due for recovery in February 1995 (on Discovery cruise 213). In addition, data have been collected on two earlier Discovery cruises (164 between December 1986 and January 1987 and 165A between February to March 1987). Discovery 164 collected CTD profiles along sections across the south west Indian Ocean and the Antarctic Circumpolar Current, and also collected XBT data. Discovery 165A collected 10 CTD profiles and SeaSoar sections (temperature, salinity, chlorophyll a) in the Agulhas retroflection area.
