Processed underway Thermosalinograph (TSG) observations from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 282, May 2022

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected on the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) cruise on the Algoa Voyage 282 between 10 May and 18 May 2022. 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). The IEP:SB in 2013 consolidated 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...

Averaged bottom temperature and dissolved oxygen in and around the Cape Canyon

Submarine canyons are internationally reported to enhance upwelling and heterogeneity. However, in South Africa such studies remain limited and thus a knowledge gap in regional submarine canyon dynamics still exists. To address this gap, the Department of Forestry, Fisheries and the Environment: Oceans and Coasts initiated a multi-disciplinary expedition onboard the RV Algoa (March 2016-2018) where oceanographic data, amongst other datasets, was collected within a 5x5 nautical mile distance. The benthic stations were linked to the associated mean bottom temperature and dissolved oxygen profiles.

Raw SDS data from Southern Ocean Seasonal Cycle Experiment (SOSCEx) IV on the SA Agulhas II, Voyage 020, July 2016

The SA Agulhas II operated from Cape Town along the Goodhope Line, completing underway biogeochemical and physical oceanography observations along the transect, as part of the Winter 2016 Southern Ocean Seasonal Cycle Experiment (SOSCEx) IV and Marginal Ice Zone Dynamics. The cruise included deployment of expendable bathythermographs underway, deployment of four autonomous robotics instruments at two stations (2 wavegliders and 2 buoyancy gliders, per station), and the deployment of two Argo floats. One CTD for instrument calibration and verification was deployed at each glider station. The transect commenced to the Marginal Ice Zone for sample collection of sea ice and biological community composition in this region. This collection includes raw Scientific Data System (SDS) data from S.A Agulhas II, Voyage 020A (AGU020A) that took place between 15 July 2016 and 29 July 2016.

Raw TSG data from the Southern Ocean Seasonal Cycle Experiment (SOSCEx) III Winter Cruise on the SA Agulhas II Voyage 016, July 2015

This is raw Thermosalinograph (TSG) data from the Southern Ocean Seasonal Cycle Experiment (SOSCEx) III Winter Cruise on the SA Agulhas II Voyage 016, 22 July to 15 August, 2015. The third Southern Ocean Seasonal Cycle Experiment (SOSCEx) III is a high-resolution full seasonal cycle experiment using integrated observational and modeling platforms. A novel aspect of SOSCEx III is the integrated multi-platform approach, which aims to explore new questions about the climate sensitivity of carbon and ecosystem dynamics in the Southern Ocean and how these processes are parameterized in models. This winter 2015 cruise can be divided into two primary tracks, the GoodHope line, between Cape Town and the ice edge along the Greenwich Meridian, and the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) line, between Cape Town and the Greenwich Meridian, at 34.5 degrees South longitude.

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

This is raw Scientific Data System (SDS) 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 Petrels...
