South African records of azooxanthellate Scleractinians (i.e., stony cold-water corals)

South African azooxanthellate Scleractinia have not been comprehensively reviewed since Boshoff’s 1980 study, despite decades of additional sampling and scattered regional reports. This study updates the country’s coral species inventory by examining museum collections, particularly from the Iziko South African Museum and the Smithsonian Institution, alongside historical imagery, recent survey data, and existing literature. The results increase the known diversity from 77 to 108 species across eleven families, including 28 new national records, three new species, and one newly described genus.

St Helena Bay Monitoring Line (SHBML) on the Ellen Kuzwayo Voyage 057, March 2010

This St Helena Bay Monitoring Line (SHBML) cruise was conducted on the Ellen Kuzwayo Voyage 057 in March 2010. 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 Southern...

Raw data collected by Seaglider SG573 off Cape Town for CTD calibration (SeaTrials 1)

The Gliders in the Agulhas (GINA) project is a multi-institutional effort to implement sustained glider observations around South Africa’s coastline to enhance existing regional networks and complement larger international observations systems such as the Ocean Gliders Boundary Ocean Observing Network (BOON). This dataset includes all data collected by Seaglider SG573 during the first GINA deployment in 2018. The Seaglider was set-up to vertically profile the water column between depths of 0 and 1000m. Measurements collected included conductivity (salinity), temperature, depth (CTD), dissolved oxygen, chlorophyll-a fluorescence (proxy for phytoplankton concentration), Photosynthetically Active Radiation (PAR) and two wavelengths of optical back-scattering by particles, Bb(470) and Bb(700) (proxies for particle concentration). In addition, information collected from the Seaglider was used to derive surface and depth averaged currents. This is raw data collected by Seaglider SG573...

Marion Island Relief on the SA Agulhas II Voyage 036, April 2019

The 2019 Marion Relief Voyage offered the 7th opportunity to conduct multi-disciplinary, shipbased marine research focusing on links and interactions between air and sea, ocean physics, chemistry, biogeochemistry and biology, including microbial, planktic and benthic communities on board South Africa’s polar research and supply vessel MV SA Agulhas II en route to, and around, the sub-Antarctic Prince Edward archipelago. The overall aim was to continue contributing to an oceanographic observation and monitoring system directed by South African research institutions in support of South Africa’s needs – and where possible, in support of global requirements of inter alia the Global Oceans Observing System (GOOS), the Southern Ocean Observing System (SOOS), the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), and the Agreement on the Conservation of Albatrosses and Petrels (ACAP). With the declaration on 9 April 2013 of the Prince Edward Islands (PEIs) as...

Processed underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 034, September 2018

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 07 September 2018 and 13 October 2018 during SA Agulhas II Voyage 034. A SeaBird SBE45 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).

Processed CTD continuous observations from the South Coast Hake Biomass on the Africana Voyage 036, October 1985

This is processed downcast Conductivity-Temperature-Depth (CTD) continuous data from the South Coast Hake Biomass on the Africana Voyage 036, collected between 15 and 26 October 1985. The cruise operated in the Agulhas Current Large Marine Ecosystem (ACLME) region on the south coast of South Africa. The first objective of this cruise was to establish, by means of surveying and trawling between 200m and 500m water depths, the feasibility of extending the hake biomass surveys to the South Coast. The area 20 E to 25 E, from 75m to 200m water depths, has already been covered during biomass surveys by Japanese research vessels, accompanied on each occasion by one of the Institute's scientists. The feasibility of trawling shallower than 200m in this region, albeit with heavy gear, has thus already been established. The second objective was to investigate, by trawling, the depth distribution of squid in the area 23 30'E and 24 30'E, from as close as possible to the coast (i.e. as shallow...

Processed CTD continuous observations from the West Coast Hake Biomass Survey on the Africana Voyage 054, June 1987

Here we present processed downcast Conductivity-Temperature-Depth (CTD) continuous data collected between 16 June and 10 July 1987, during the West Coast Hake Biomass Cruise on the Africana Voyage 054, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South 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. The scientific targets of the trip revolved around the determination of biomass index of both Cape hake species off the South African west coast. The diurnal cycle of Cape hake and their relationship with environmental parameters was also studied. Some hake material were collected in South West African waters. Deep-water trawls were made to delimit the offshore extent of hake distribution and to collect rare specimens of fish for accession to museums. Demersal community interrelationships were studied, as...
