What are your plans for this takeover?
Into our 41st uninterrupted year of continuous monitoring! Takeover is mostly dedicated to training the new overwintering personnel, because most of the action (from a seal perspective) on the island take place outside takeover timeframes. Many long-term questions, aimed at understanding the ecology of the various species populations and their interactions with a changing environment, are pursued.
What are the main interest of the MIMMP in the sub-Antarctic region?
We are interested in how seal and killer whale populations change as the environment changes.
In more detail:
MIMMP does long-term ecological monitoring and research of four marine mammal species (Southern elephant seals, Antarctic – and Subantarctic fur seals, and Killer whales) at Marion Island. Focused primarily on population and foraging ecology, interactions between species and with their changing environments.

World Wetlands Day, is celebrated every year on 02 February. On this day, in 1971, the Convention on Wetlands of International Importance (Ramsar Convention) was signed in Ramsar, Iran.
World Wetlands Day is celebrated to to “raise awareness and understanding of what wetlands are and how we can contribute towards restoring them through making conscious choices, becoming persuasive voices and taking bold actions” (read more here).
What is a wetland?
A wetland is defined as the land which is transitional between terrestrial and aquatic systems where the water table is usually at or near the
surface, or the land is periodically covered with shallow water, and which land in normal circumstances supports or would support vegetation typically adapted to life in saturated soil (1).
Why is wetland restoration so important? Listed below are a few benefits of wetland restoration:
- Enhanced biodiversity
- Improve water supply
- Store carbon
- Reduced impacts from flooding
- Improve livelihoods
- Enhance well–being
- Protection of agricultural resources (1; 2)
Is your role in wetland restoration important?
Yes! Our individual and collective actions have an impact (1).
What can you as individual do to help protect and preserve wetlands?
- Participate in programs that help protect and restore wetlands.
- Report illegal actions such as unauthorized wetland fill or dredging activities to government authorities
- Pick up litter and dispose in appropriate trash containers. Keep surface areas that wash into storm drains clean from pet waste, toxic chemicals, fertilizers and motor oil, which can eventually reach and impair our wetlands.
- Use native species when planting trees, shrubs and flowers to preserve the ecological balance of local wetlands.
- Avoid wetland when you are expanding your house.
- Use phosphate-free laundry and dishwasher detergents. Phosphates encourage algae growth, which can suffocate aquatic life.
- Use non-toxic products for household cleaning and lawn and garden care. Never spray lawn and garden chemicals outside on a windy day or on a day that it might rain and wash the chemicals into waterways.
- Enjoy the scenic and recreational opportunities wetlands offer, while preserving their integrity for future generations by minimizing the use of heavy equipment and staying in designated visitor areas where available (3).
Did you know that the South African Prince Edward Islands (Prince Edward Island and Marion Island) is declared as Wetland of International Importance?
The Prince Edward Islands was declared Wetland of International Importance: Ramsar Site No.1688, on 22 May 2007. The conservation and management of this site falls within the responsibility of the Directorate: Southern Oceans and Antarctic Support of the Department of Forestry, Fisheries and the Environment.

Media Release by the Department of Forestry Fisheries and the Environment
Minister Barbara Creecy visits Antarctica, 9 to 12 Jan
Forestry, Fisheries and the Environment Minister, Ms Barbara Creecy, will on Monday (9 January 2023) visit the Princess Elisabeth Antarctic Research Station as a guest of the Government of Belgium for four days.
The Ministerial visit to the research station is being hosted by the Government of Belgium and the International Polar Foundation, as the operator of the Princess Elisabeth Antarctica under mandate from the Belgian Polar Secretariat.
While at the base the Minister will have an opportunity to learn more about the first zero emissions research station in Antarctica, which has become a showcase for best practice in the use of renewable energies to reduce the environmental impact of operations on Antarctica. The Belgians have expressed their desire to sharing Best Practice to improve the environmental performance of the South African Research Infrastructure in Antarctica.
The Belgian Antarctic Research Expedition (BELARE) uses Cape Town as its gateway.
On Tuesday, 10 January 2023, Minister Creecy will travel from the Belgian base to the South African Antarctic Programme’s Research Station, known as SANAE IV, in Queen Maud Land. At the base, which is managed and administered by the Department of Forestry, Fisheries and the Environment, Minister Creecy will interact with station crew and also inspect the facilities used by the South African scientists. During the visit to the biodiversity hotspot, the Minister will learn about the threats of pollution and research into the human impact on ocean and marine ecosystems threatened by global climate change and earth systems observations.
The S.A. Agulhas II departed Cape Town in December with the team for 2023, also delivering equipment, supplies and fuel.
The department has maintained South Africa’s research presence in Antarctica and the Prince Edward Islands. The scientific data that is collected during voyages is critical to the understanding of amongst other things, the impacts of climate change and weather information associated with extreme events.
The first South African built Antarctic base, a wooden structure, SANAE I, was a Meteorological research station constructed in 1961/62. South Africa has not only maintained an uninterrupted presence in the Antarctic since 1960 but played an active role in the management and conservation of the vast continent and contributed to the pool of scientific knowledge.

Contemporary and Future Drivers of CO2 and Heat in the Southern Ocean
The contemporary Southern Ocean mitigates the effects of anthropogenic climate change through its disproportional uptake of carbon and heat. However, it is not well understood how this role will evolve under different emission and mitigation scenarios. The Southern Ocean also remains the largest source of global ocean uncertainty in the global estimates of CO2 and heat fluxes. While much has been achieved globally and regionally in constraining the variability and some of the mechanisms that drive Southern Ocean CO2 and heat fluxes separately, we propose that a significant part of the challenge lies in the lack of research on CO2 and heat together to better understand the feedback and the mechanisms that drive those feedbacks.
This SANAP-NRF project aims to examine the changing role of the Southern Ocean in global climate by looking at the two main drivers CO2 and heat, in an integrated way using an unprecedented 10-year high resolution glider dataset from the 2012-2022 SOSCEx experiments, prognostic biogeochemical models, and new observational experiments planned in partnership with CSIR and DFFE as well as the SO-CHIC EU H2020 project. This collaboration is undertaken as part of the emerging National Ocean CO2 Facility, a research infrastructure integration between CSIR and DFFE within SAPRI and hosted at DFFE.
We aim to gain a better understanding of how the interaction of atmospheric synoptic cycles (storms) and fine-scale (0.1-100 km) ocean processes influence seasonal-decadal variability of CO2 and heat fluxes. This will include the extent to which they feedback on each other and ultimately contribute to a better understanding of the role of the Southern Ocean in the global carbon-climate system.
The expected three outcomes are:
- Improved observational constraints for the contemporary seasonal-interannual variability of CO2 and heat fluxes.
- Understanding of how storms and their interaction with fine-scale dynamics influence the seasonal and interannual variability of CO2 and heat fluxes.
- Identify the potential mechanisms that could explain the decadal anomaly in CO2 fluxes at the end of the 20th century.
Winter cruise sampling:
The SCALE Winter-2022 cruise provides an important opportunity to address a key source of uncertainty in annual Southern Ocean CO2 and heat observations – the dearth of winter time observations. While the lack of winter observations has been improved by the recent proliferation of SOCCOM floats, ship-based observations remain highly valuable as an independent and direct measurement of CO2 and importantly include heat flux observations. On the SCALE Winter-2022 cruise, the CO2-Heat team will be sampling profiles of dissolved inorganic carbon (DIC) and Total Alkalinity. The underway pCO2 system will also be operated during the cruise. Simultaneously, the heat flux sensors are in continuous operation measuring the short and long-wave radiation on minute time-scales. In addition, as part of SO-CHIC, two Saildrones will overlap with the ship sampling path for calibration of measured CO2 and heat flux. The Saildrones will remain in the Southern Ocean sampling heat and CO2 fluxes for the remainder of winter. These key winter observations will be contrasted to the previous summer observations made during the dedicated SO-CHIC cruise in January 2022.
