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...

Cape Canyon Benthic Invertebrates Tissue samples

Submarine canyons are heterogeneous environments known to support a variety of benthic organisms, and often considered biodiversity hotspots. Canyon morphological features facilitate the funneling of organic matter to the seabed, making them significant hubs of food resources for benthic life. In light of this, the DFFE: Oceans and Coasts initiative undertook the collection of benthic tissue data aimed at understanding how hydrography affects food availability for benthic species within and surrounding the Cape Canyon. This effort involved examining 15 stations, comprising six within the canyon and nine outside it, leading to the identification of six distinct trophic groups.

This is processed Conductivity, Temperature, Depth (CTD) data from the IIOE2 on SA Agulhas II Voyage 028 from October - November, 2017. The International Indian Ocean Expedition 2 is a collaborative regional cruise to build capacity and strength within Africa. The focus will be on developing students in the region in the areas of physical oceanography, chemistry, biological oceanography, benthic biodiversity, marine top predators and marine plastics. This dataset was processed using older standards which may not align with international best practices and the standards currently adhered to by the Department of Forestry, Fisheries and the Environment (DFFE). The Department is re-processing and replacing data to ensure everything has the same format and is of the same quality and datasets will be marked as obsoleted once that is done. As such the user assumes the entire risk related to the use of these data in its current state and format. DFFE disclaims all warranties of the data...

CTD and bottle test data during GINA 2017 for Seaglider SG574 collected in Cape Town harbour

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). Ocean gliders are robotic platforms operated and piloted from land. The Seaglider during GINA 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 test CTD and Bottle data, collected outside of Cape Town...
