Converted CTD data from the Pelagic Biomass Survey on the Africana Voyage 290, October 2016

This is converted Conductivity, Temperature, Depth (CTD) data from the Pelagic Biomass Survey on the Africana Voyage 290 from 25 October - 14 December 2016. The cruise operated from Hondeklip Bay to Port St Johns, South Africa.The principal aim of the Pelagic Biomass Surveys is to obtain estimates of the total biomass of anchovy, sardine and west coast round herring and to obtain data on their population length frequency compositions, for input to the operational management procedure (OMP) for making Total Allowable Catch (TAC) recommendations for the following year. The surveys also obtain information on the environment and food regime impacting anchovy, sardine and west coast round herring around the coast, although recent surveys (~2009 onwards) have included much less environmental sampling than earlier years. The survey uses hydro-acoustics to estimate fish density and abundance, and midwater trawling to identify acoustic targets and to obtain length frequency and other...

The survey uses hydro-acoustics to estimate fish density and abundance, and midwater trawling to identify acoustic targets and to obtain length frequency and other biological data, and ichthyoplankton and environmental sampling are also conducted. The abundance and biomass estimates from these surveys are an essential input into the management process and serve as a scientific basis for the...

Sardine, Hake, and Anchovy Recruitment Programme (SHARP) / St. Helena Bay Monitoring Line (SHBML) on the Africana Voyage 280, February 2012

At the intiation of the original SARP project the operational objective was to investigate variability in the transport of clupeoid eggs and larvae by the Benguela jet current from the south coast spawning grounds to the west coast nursery area as this would impact recruitment, thereby influencing the abundance of pelagic resources. To date 17 years worth of data have been collected on a transect perpendicular to the coast off Slangkop, the SARP line. Many valuable conclusions have been drawn using the information. Though the SARP line has contributed to its initial goal, the wealth of data and knowledge accumulated over the years suggests it is time for a revamp and extension of the SARP line. The idea is to strengthen the sampling strategy to include a more comprehensive experimental design that not only targets clupeoid eggs and larvae but also the early life stages of another highly valuable fisheries-targeted resource, the Cape hakes (Marluccius capensis and M. Paradoxus), and...

St Helena Bay Monitoring Line (SHBML) on the Africana Voyage 275, August 2011

This St Helena Bay Monitoring Line (SHBML) cruise was conducted on the Africana Voyage 275 from 1 to 5 August 2011. This is a long-term monitoring line conducted off the coast of Elands/St Helena Bay on the west coast of South Africa. SHBML started in 2000 as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims were to obtain seasonal and interannual information on the hydrology and productivity of the area. It was incorporated under the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) in 2013 consolidating a long-term, multi-decadal time-series (from 1951 onward) of information for this important region and has continued monitoring in the form of the IEP:SB. The programme is a multi-disciplinary, collaborative and capacity building platform undertaking relevant science, including updating technology, with the aim to develop ecosystem indicators that can be used to effectively monitor and understand the...
