South Coast Demersal Inshore Biomass Survey on the Africana Voyage 106, September 1992

The South Coast Demersal Inshore Biomass Survey was conducted on the Africana Voyage 106 from 02 to 23 September 1992. The objectives of the survey were to conduct a stratified bottom trawl survey to assess the biomass, abundance and distribution of hake, sole, horse mackerel, squid and other trawl species with emphasis on 'inshore' fishing areas for recruitment estimates; to investigate the hydrology and current profiles of the South Coast and to relate this to the distribution pf the major demersal trawl species. This included five transects extending from specified areas in the South Coast and approximately perpendicular to the coastline out towards the main stream of the Agulhas Current. A 'mini' CTD transect grid in the Cape St Francis area was also done; to do a selected number of midwater trawls to investigate the distribution and abundance of deep-water fauna; to conduct routine biological and length frequency sampling of demersal species; to sample squid intensively to...

The Benguela Current Sources and Transport (BEST 1) was conducted on the Africana Voyage 105 from 16 June 1992 to 05 July 1992. The objectives of the survey was the quantification of the flux and Agulhas rings penetrating the South-East Atlantic and the influence of these on the shelf waters and resources of the Benguela system; the provision of a large-scale environmental time-series lasting for a continuous period of 18 months. This was used to validate processes inferred from satellite imagery, thereby enhancing utility of the latter for fisheries environmental monitoring as needed for fisheries research; determination of the distribution and abundance of rock lobster larvae in the South-East Atlantic, to supplement the existing data which were collected in April 1989. This formed an integral part of the Institute's rock lobster research (West Coast rock lobster spend at least one year traversing the South Atlantic gyre before settling on the West Coast); water column and...

Chl-a data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on Algoa Voyage 246, February 2018

First look at Chl-a data from a survey of West Coast of South Africa, Algoa Voyage 246, as part of the Integrated Ecosystem Programme from the 15 to 22 February 2018. IEP:SB focuses on the biologically productive, cold waters of the Benguela Current Large Marine Ecosystem, which are inherently variable on short time-scales and responsive to changing weather patterms. The research aims to provide relevant, reliable and improved assessment of the ecosystem, in support of its effective management, preservation and conservation, so that South Africans can benefit from a healthy and well-functioning ocean environment. The overarching objective is to enhance understanding in process studies by assessing the importance, timing and magnitude of mechanisms and processes that influence the Southern Benguela ecosystem structure and functioning, including the climate variability.
