Cape fur seal (Arctocephalus pusillus pusillus) pup trends at breeding colonies within the proposed Sandveld Coastal Complex Protected Area Management Plan

This report focuses on the trends of Cape fur seal (Arctocephalus pusillus pusillus) pups within the proposed Sandveld Coastal Complex (SCC) Protected Area Management Plan at various breeding colonies. CapeNature is currently in the process of developing a Management Plan for the Sandveld Coastal Complex (SCC) Protected Area, in compliance with the National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003). The SCC harbors significant breeding sites for Cape fur seals at Elephant Rock, Paternoster Rocks, Penguin (Bird) Island-Lambert’s Bay, and Jacobs Rock (also known as Jacob’s Reef).

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).

State of the ocean and coasts around South Africa 2016 report card

Please note that the contact information included in the report is superseded by the contact information that can be found in the Responsible Parties field of this metadata record. This report is compiled primarily by staff within the Chief Directorate: Oceans and Coasts Research that resides within the Branch: Oceans and Coasts. Contributors from outside the Department are acknowledged. The Branch maintains and seeks to grow human capacity and infrastructure in all aspects of marine sciences towards improving understanding and management of marine ecosystems. In this report, DEA provides updated information on the status of some parameters for South Africa’s oceans and coasts, ranging from chemical and physical properties to biological assessments. These have been selected as potentially-useful indicators of the change, health and management of South Africa’s marine ecosystems. The format of this report card is aimed at providing a brief overview of the research and monitoring...

State of the oceans around South Africa: 2014

Please note that the contact information included in the report is superseded by the contact information that can be found in the Responsible Parties field of this metadata record. A series of reports on State of the Oceans around South Africa, produced by Branch Oceans and Coasts of South Africa’s Department of Environmental Affairs, was introduced in December 2006. The reports initially considered environmental parameters for the purposes of establishing general principles, such as annual cycles, and long-term trends, which may provide insight into the local effects of global warming and climate change. The reports were intended to provide an overview of marine environmental conditions that prevailed during the preceding year, which may be of relevance to the management of South Africa’s marine and coastal resources and infrastructure. To this end, use was made of data from a variety of sources, including websites, satellite sensors, the South African Weather Service, coastal and...

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.

Marion Island Relief on the SA Agulhas II Voyage 036, April 2019

The 2019 Marion Relief Voyage offered the 7th 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 (CCAMLR), and the Agreement on the Conservation of Albatrosses and Petrels (ACAP). With the declaration on 9 April 2013 of the Prince Edward Islands (PEIs) as...
