“Celebrating 30 Years of Freedom Towards Women’s Development”
In the SANAP community we are celebrating all those involved as Researchers, Scientists, and Students at tertiary and research institutions and infrastructures, and personnel within the National Research Foundation, the Department of Forestry, Fisheries and the Environment, the Department of Public works and Infrastructure, the South African Weather Services, the South African National Space Agency, the South African Polar Research Infrastructure and all the women serving as part of the crew of the S.A. Agulhas II.
Celebrating our women overwintering team members at our stations: Antarctica (SANAEIV), Marion Island and Gough Island.
2024 women’s day commemoration is a reminder of the important contributions that are made by women to society, as well as a time to reflect on the advances in women’s rights. During 30 years of democracy, South Africa has made significant strides in advancing gender equality in all domains of society, including economic empowerment of women.
Women’s Day 2024 is the first national day led by the Government of National Unity (GNU) and takes place in a rural community as part of including all South Africans in national events, and placing a focus on the achievements and needs of women in all corners of the country. President Cyril Ramaphosa is expected to officiate the national Women’s Day commemoration in Pofadder in the Namakwa District, Northern Cape. – SAnews.gov.za
More about the South African Weather Service team on the recent Gough Island takeover expedition.

The South African Weather Service (SAWS) has been part of the South African National Antarctic Programme (SANAP) from the beginning, when the first team was appointed to stay on Gough Island. The metkassies (meteorological overwintering team members) continue to contribute to a long history of data collection on Gough Island. This includes an automatic weather station that measures temperature, wind speed and direction, humidity, and pressure.
What can the new overwintering team on the island look forward to?
The metkassies when on shift do visual observations which includes cloud height and type, horizontal visibility, precipitation type, weather present and past and sea temperature. Formal observation is done every hour from 06:00GMT until 15:00GMT and then every 3 hours during night shift. This is done every day of the week.

Phytoplankton are microscopic plants that live in the ocean, and just like plants on land they need to have enough food to grow and be happy. However, some places in the ocean don’t have enough food for them whereas some places do. The Southern Ocean Carbon & Climate Observatory (SOCCO) team based at CSIR, Trace Metals team based at Stellenbosch University (TracEx) and the Department of Forestry, Fisheries and the Environment: Oceans and Coasts team are trying to figure out where those places are (in the Southern Ocean).
During the Gough Island takeover expedition:
The Trace Metal Biogeochemistry research teams sampled upstream and downstream of Gough Island to look at how the Antarctic Circumpolar Current (ACC) interacts with the island to resuspend sediments from the seafloor. This resuspended sediments acts as a source of trace metals to the surface mixed layer in support of phytoplankton blooms. The team used a 12 bottle mini-CTD rosette system (see image below, right) to sample for dissolved trace metals, particulate trace metals and organic trace metal chemistry.

The project in more detail:
The Southern Ocean (SO) is one of the largest high-nutrient low-chlorophyll regions in the World’s Ocean, where primary productivity is limited by iron bioavailability, thereby impacting the strength and efficiency of biological carbon pump. There are, however, exceptions with large phytoplankton blooms persistently observed downstream of the sub-Antarctic Islands. While extensive research has focussed on iron-biogeochemistry around Kerguelen and Crozet islands, no such studies have been conducted at Marion and Gough islands.
Furthermore, whilst our previous studies have made substantial advances toward addressing the gaps in seasonal data coverage through the Southern oCean seAsonaL Experiment (SCALE) 2019 winter and spring expeditions, there is still a paucity of dissolved iron data in the SO, especially from autumn to late spring. This is severely hampering our understanding of the full seasonal biogeochemical iron cycle and its impact on primary production. This project aims to continue its focus on seasonality by expanding seasonal coverage of iron measurements to include autumn (Marion) and late-spring (Gough) expeditions for more comprehensive coverage of the SO seasonal cycle, with a particular focus on quantifying biogeochemical cycling of iron-pool around these understudied islands.
This project is funded by: The National Research Foundation, South African National Antarctic Programme funding (NRF-SANAP).
Situated in the South Atlantic Ocean, positioned equidistantly between South Africa and South America, lies a highly significant breeding ground for seabirds known as Gough Island. This remote island serves as the breeding habitat for 24 distinct avian species, many of which are found nowhere else on the planet. Regrettably, the avian inhabitants now share their home with an invasive species, specifically the house mouse. These non-native mice, introduced to the island by human activity, are causing severe harm to the island’s native wildlife, including plants and animals that have thrived there for millennia. The mice’s voracious appetite leads to the consumption of over two million seabird eggs and chicks annually, driving certain species perilously close to extinction.
In an effort to safeguard the birds, the Gough Island Restoration Programme was launched with the aim of eradicating the mice. In 2021, the Gough Island Restoration Programme attempted to eradicate mice from the island in one of the most challenging and logistically complex island eradications ever ventured.
Although the endeavor did not achieve complete success, it significantly reduced the mouse population, providing a respite for the birds. During this period, the avian inhabitants managed to successfully raise numerous chicks.
Scientists continue to monitor the birds and gather valuable information that will hopefully aid in future endeavors to eliminate the mice entirely. Part of this takeover and the overwintering field team’s work programme will relate to follow-up activities to further underpin efforts to restore Gough Island.

More about the work on the island for this takeover:
“During takeover our team is carrying out a census of Tristan Albatrosses and Southern Giant Petrels across the whole island, the so-called round island survey. At this time of year, the Southern Giant Petrels are starting to breed while the Tristan Albatross chicks are about to fledge. The number of fledged Albatross chicks will then be compared to numbers of breeding pairs that were counted at the beginning of the year and so breeding success for this Critically Endangered bird can be calculated (more than 99% of the global population breed exclusively on Gough Island). The round island survey also provides the team with the opportunity to monitor the abundance and distribution of the two landbird species, the Gough Bunting and the Gough moorhen. This takeover the team will also be taking some soil samples from the upland parts of the island. This is to help monitor the ecosystem in the wake of the mouse eradication attempt”.

The RSPB overwintering team members’ work:
They will focus on Gough’s bird life, monitoring the breeding success of species, providing estimates of their populations and survival and documenting the impacts of House Mice.
