Long-term observations of hourly bottom temperatures at Nosy Ve, Madagascar

Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Nosy Ve, Madagascar. At selected sites around Southern Africa, UTRs have been used to obtain long-term records of bottom temperatures in the nearshore environment, at depths ranging from 2m to 34m.

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 SDS data from the Marion Island Annual Relief Voyage on the SA Agulhas II Voyage 024, April 2017

This is raw Scientific Data System (SDS) data from the Marion Island Annual Relief Voyage on the MV SA Agulhas II Voyage 024, 06 April to 12 May 2017. The 2017 Marion Relief Voyage offered the fifth 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...

Long-term moored observations at the Prince Edward Island archipelago

Here we present long-term observations from the Prince Edward Island (PEI) shelf moorings. These moorings form part of the South African component of the International South Atlantic Meridional Overturning Circulation project (SAMOC-SA), which aims to characterize the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa.

Processed Expendable Bathythermograph (XBT) casts collected during the 2017 Marion Relief Voyage on SA Agulhas Voyage 024

The South African component of the international South Atlantic Meridional Overturning Circulation project (SAMOC-SA) aims to characterise the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa. The Crossroads monitoring line, directly under the altimetry track N198, is sampled annually during the Marion Relief voyages, using a combination of CTD stations and XBT casts, where the XBT casts are done, at set intervals, between CTD stations to complement the CTD data. Here we present 34 processed XBT casts collected along the Crossroads Transect, between 06 May 2017 and 11 May 2017, during the 2017 Marion Relief Voyage.
