Short-term observations of hourly bottom temperatures at the Walters Shoal, southwest Indian Ocean at location WSN01 (25 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...

Effectiveness of Table Mountain National Park Marine Protected Area project (2017-2021)

Intertidal rocky shores are the most accessible marine habitats and therefore heavily impacted by harvesting. In recent years, they have also been increasingly invaded by alien species, which compounds the effects of harvesting on rocky shore community composition and functioning. Recent survey data, combined with historical data from 1970, were used to assess temporal changes over the intervening period in rocky shore communities at two sites (Wireless Point and Wireless Island).

Processed Expendable Bathythermograph (XBT) casts collected during the 2019 Marion Relief Voyage on SA Agulhas Voyage 036

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 57 processed XBT casts collected along the Crossroads Transect, between 10 May 2019 and 14 May 2019, during the 2019 Marion Relief Voyage.
