West Coast Demersal Survey on the Africana Voyage 133, January 1996

The West Coast Demersal Survey was conducted on the Africana Voyage 133 from 12 January to 20 February 1996. The objectives of the cruise were to survey by means of trawling the abundance of adult and recruiting hake in South African waters; to conduct routine biological and length frequency sampling of demersal species; to investigate the environmental and ecological inter-relationships of hake and other demersal species; to investigate the occurrence, distribution, reproduction and abundance of squid species; to investigate the distribution and biology of demersal species in water at depths greater than 500 m by means of demersal trawling; to sample catches for hake sex ratios and frequency of gill parasites; to conduct demersal environmental studies including intercalibration of bottom temperature measurements with commercial trawlers, CTD and ADCP measurements at ALL trawl stations and other specified stations, and box cores and transmissometer profiles at HODSA sites on the...

Processed CTD continuous observations from the West Coast Demersal Survey on the Africana Voyage 133, January 1996

Here we present processed downcast Conductivity-Temperature-Depth (CTD) continuous data collected between 13 January and 19 February 1996 during voyage 133 on the Africana in the Benguela Current Large Marine Ecosystem (BCLME) on the west 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.

Processed CTD continuous observations from the West Coast Demersal Biomass Survey on the Africana Voyage 139, January 1997

Here we present processed Conductivity-Temperature-Depth (CTD) continuous data from the downcast collected between 9 January and 30 January 1997, during voyage 139 on the Africana, in the Benguela Current Large Marine Ecosystem (BCLME) on the west 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.

West Coast Demersal Biomass Survey on the Africana Voyage 139, January 1997

The West Coast Demersal Biomass Survey was conducted on the Africana Voyage 139 from 8 January to 30 January 1997. The objectives of the cruise were to survey, by means of trawling, the abundance of adult and recruiting hake in South African waters; to conduct routine biological and length frequency sampling of demersal species; to investigate the environmental and ecological inter-relationships of hake and other demersal species; to investigate the occurrence, distribution, reproduction and abundance of squid species; to investigate the distribution and biology of demersal species in water at depths greater than 500 m by means of demersal trawling; to sample catches of hake for sex ratios and frequency of gill parasites; to conduct demersal environmental studies including intercalibration of bottom temperature measurements with commercial trawlers, and CTD and ADCP measurements at all trawl stations and other specified stations; the collection of specimens for the South African...
