Short-term observations of daily currents at the Walters Shoal, southwest Indian Ocean at location WSS01 (30 May 2014 - 02 August 2015)

The Walters Shoal project, part of the broader African Coelacanth Ecosystem Programme (ACEP III), conducted an oceanographic and biological survey of the Walters Shoal, a shallow seamount in the southwest Indian Ocean, in order to understand the biodiversity and ecological processes occurring on this unique seamount. The project used a multidisciplinary approach that included the sampling of sponge fauna, fish populations, and oceanographic conditions. Oceanographic data (including moored ADCP data, CTD profiles, as well as underway S-ADCP and TSG data) was collected to understand the circulation patterns and hydrography that could influence the biological communities on the seamount. Here, we present the moored ADCP data that was collected to determine currents and sub-surface temperatures. Two ADCP moorings were deployed, one on the northern part and the other on the southern part of Walters Shoal, at depths of 500m, between May 2014 and August 2015. Here we present processed...

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...

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 Conductivity, Temperature, Depth (CTD) data from S.A Agulhas II, Voyage 020A (AGU020A) that took place between 15 July 2016 and 29 July 2016.
