Processed underway Thermosalinograph (TSG) observations from Algoa Voyage 209, August 2014

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected, between 05 August and 12 August 2014, during voyage 209 on the RS Algoa. A SeaBird SBE45 Thermosalinograph (TSG) is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with navigational information. A temperature sensor close to the intake provides temperature measurements of the incoming water (T1). The temperature of the water inside the conductivity cell (T2) is used to accurately compute salinity (S) from the conductivity measurements (C).

Raw CTD data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 015, April 2015

This is raw Conductivity, Temperature, Depth (CTD) data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 015 from 9 April to 15 May, 2015. The 2015 Marion Relief Voyage on board South Africa’s polar research and supply vessel MV SA Agulhas II offered yet another opportunity to conduct multi-disciplinary ship-based oceanographic research focusing on links and interactions between air and sea, ocean physics, chemistry, biogeochemistry and biology, including microbial, planktic and benthic communities. The overall aim was to continue contributing to the establishment of an oceanographic observation and monitoring system directed by South African research institutions in support of South Africa’s needs – and where possible, the global requirements of the Global Oceans Observing System (GOOS), the Southern Ocean Observing System (SOOS), the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), the Agreement on the Conservation of Albatrosses and...

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

This is processed 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...
