This is processed Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA) data from the Integrated Ecosystem Programme cruise in the Southern Benguela (IEP-SB). The cruise took place from 7 to 12 August 2014 aboard the RV Algoa. A total of 41 stations were occupied along three transect lines on the west coast of South Africa. Eight Conductivity, Temperature, Depth (CTD) stations were occupied along the Kleinsee monitoring line (KML) off Kleinsee, nine along the Namaqua Monitoring Line (NML) of Namaqua, twelve stations along the St Helena Bay Monitoring Line (SHBML), two separate stations in the low oxygen zone in St Helena Bay, and ten stations along the Scarborough Monitoring Line (SCL) off Cape Columbine. Discrete water samples were collected in 500ml Certified Reference Materials (CRM) bottles from Niskin bottles and spiked with 0,02% of Mercuric chloride before being stored in the dark at room temperature for later analysis in the laboratory ashore using a Versatile...

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.

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...

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 NDS data from the St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 194, February 2013

This is raw Network Data System (NDS) data from the St Helena Bay Monitoring Line February 2013 cruise (now under the Integrated Ecosystem Programme: Southern Benguela). The St Helena Bay Monitoring Line was initiated as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims are to obtain seasonal and interannual information on the hydrology and productivity of the area. Data on harmful algal blooms, low oxygen water and intrusions of Agulhas Bank water along the west coast will also be collected. A long-term, multi-decadel time-series (from 1951 onward) of information already exists for this important region and has continued in the form of the IEP:SB to detect long-term changes in the hydrology and the plankton, which are important for the detection of regime shifts.
