The Pelagic Pre-Recruit Survey was conducted on the Africana Voyage 143 from 6 March to 27 March 1997. The objectives of the cruise were to profile currents by means of the Acoustic Doppler Current Profiler (ADCP); to estimate the biomass and population structure of pelagic pre-recruit fish off the West Coast by means of echo integration and midwater trawling; to investigate the extent of pelagic pre-recruit distribution and biomass index between Cape Columbine and Cape Infanta; to collect biological material for condition studies on pelagic pre-recruits; to collect ichthyoplankton samples and hydrological data along the weekly SARP line; to collect rock lobster phyllosoma and pueruli larvae for bioenergetic studies; and to collect environmental data.
Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the downcast collected between 08 March and 25 March 1997, during voyage 143 on the Africana, in the Benguela Current Large Marine Ecosystem (BCLME) on the west coast of Southern Africa and in the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000.
