State of the marine environment off South Africa: July 2007

Please note: 1. This report has not been peer-reviewed; 2. The conditions of use outlined in the report are superseded by the conditions specified by the License field in this metadata record; 3. The contact information included in the report is superseded by the contact information that can be found in the Responsible Parties field of this metadata record.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 is the second in a new series of informal reports introduced in December 2006, intended to provide an overview of marine environmental conditions off South Africa. The reports are based on data from a variety of sources, including web sources, satellite sensors, the South African Weather Service, MCM's coastal and moored instruments and MCM's research cruises and inherent to all of these there is an inevitable lag between the time of data capture and the time when the data first become available for use. The lags are all different. For example, wind data from the Cape Point lighthouse is updated monthly, the moored...

Annual plankton report 2017 - 2018

Please note that the contact information included in the report is superseded by the contact information that can be found in the Responsible Parties field of this metadata. This report is a collation of documents and outputs from a variety of plankton monitoring activities conducted on the west, south and east coasts of South Africa and in various parts of the Southern Ocean (during annual relief voyages to South Africa’s Antarctic and sub-Antarctic research bases) over the past financial year 2017/18. It includes pertinent (plankton-related only) sections of scientific Cruise Reports, CPR tow summaries, contributions to the State of the Oceans and Coasts around South Africa 2017 Report Card, contributions (as oral and poster presentations) to scientific conferences, symposia and workshops, and book chapters and scientific papers submitted to peer reviewed journals in various stages of the publication process.It should be noted that in most cases, the samples of plankton...

Annual State of the Oceans reports

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 moored instruments, and research and monitoring cruises. Intrinsic to all of these data series is an inevitable lag between the time of sample collection or data capture and the...

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...

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.

Processed drop camera data to investigate benthic invertebrate fauna and associated habitats of the Southern Benguela Ecoregion on Algoa Voyage 263, August 2019

This is processed drop camera data from the Southern Benguela Cruise, which was conducted in the Southern Benguela Ecoregion on the Algoa Voyage 263, August 2019. This study focuses on providing a better understanding of the benthic invertebrate communities and associated habitats of three priority areas within the southernmost portion of the Southern Benguela Ecoregion. This includes Robben Island, the Table Mountain National Park Marine Protected Area (TMNP MPA) and the newly proposed Seas of Good Hope Ecologically and Biologically Significant Area (EBSA).
