SA-West Hindcast V1.0

The SA-West Hindcast V1.0 product provides a 32 year historical representation of the ocean state for the west coast of South Africa. The model was developed using the Coastal and Regional Ocean COmmunity (CROCO) modelling system. The model curvilinear grid has a variable horizontal grid resolution (1 – 2.5 km) which increases toward the coast. The model has 30 terrain-following (sigma) vertical levels. Open boundary conditions for the model are obtained from GLORYS12V1. Surface forcing is interpolated from ERA5. Model bathymetry is interpolated from digital navigation charts provided by SANHO. This configuration does not include tides. The model configuration files can be found at the somisana-croco github repository using compile options in the `C01` directory in the provided link. NetCDF model output files are available as daily averages throughout the water column, and hourly averages for the surface layer of the model. Subsets of the files can be downloaded via Thredds...

SA-Southeast Hindcast V1.0

The SA-Southeast Hindcast V1.0 product provides a 10 year historical representation of the ocean state along the southeastern coast of South Africa centered around Algoa Bay. The model was developed using the Coastal and Regional Ocean COmmunity (CROCO) modelling system. The model curvilinear grid has a variable horizontal grid resolution (0.5 – 3 km) which increases toward the coast. The model has 30 terrain-following (sigma) vertical levels. Open boundary conditions for the model are obtained from GLORYS12V1. Surface forcing is interpolated from the 3 km resolution Wind Atlas for South Africa (WASA) product provided by the Climate Systems Analysis Group (CSAG). Model bathymetry is interpolated from digital navigation charts provided by SANHO. This configuration does not include tides. The model configuration files can be found at the somisana-croco github repository using compile options in the `C01` directory in the provided link.

Processed CTD continuous observations from the Physical Oceanography Gear Trials on the Africana Voyage 091, April 1991

Here we present processed downcast Conductivity-Temperature-Depth (CTD) continuous data collected, between 29 April and 30 April 1991, during voyage 091 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000.

Long-term observations of hourly bottom temperatures at Port Nolloth, South Africa

Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Port Nolloth, South Africa. 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.

Experimental manipulations of the density of Cymbula granatina on rocky shore community

Densities of a commonly-harvested intertidal limpet Cymbula granatina were manipulated at two sites within a no-take marine protected area on the west coast of the Cape Peninsula in South Africa, using four treatment levels ranging from zero to maximum natural densities, together with control plots, to evaluate the effects of different harvesting intensities on rocky shore community composition. Following removal or thinning of C. granatina, community composition changed: cover of corticated and ephemeral algae increased and recruitment of C. granatina decreased. These outcomes were, however, dependent on the time frame considered, as algae underwent an annual cycle, and the effects of limpet removal were evident predominantly during the summer upwelling season when the algae proliferated. The management implications of the results of this experiment are discussed.

Long-term moored observations from the eastern part of the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA)

Here we present long-term observations from the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) transect in the Cape Basin region along 34.5°S. SAMBA forms part of the South African component of the International South Atlantic Meridional Overturning Circulation project (SAMOC-SA), which 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.
