The first ocean session covered the Antarctic sea ice research field led by the Sea Ice Team from the Marine and Antarctic Research for Innovation and Sustainability (MARiS). The research themes covered in this session were innovation and development, oceans and marine eco-systems under global change and earth systems observations. The presentations and posters under these research theme covered a diverse range of projects from large-scale sea ice observations, tracking and measurements to the small-scale sea ice dynamics, properties and biogeochemistry. Antarctic sea ice research has received a comparatively limited focus compared to its Arctic counterpart. The MARiS sea ice team is constituted of the departments of Oceanography, Electrical and Chemical Engineering at the University of Cape Town, with projects aimed to contribute new insights and push the boundaries within this research domain. The presentation within this session were on a variety of earth system observations models, simulations of sea ice wave interactions, innovative tool development for lab-based experiments and field-based work investigating sea ice dynamics and properties and the ecological impacts of algae and their biogeochemical significance. The session under the MARS theme; Oceans and marine ecosystems under global change was chaired by Principal investigator Tokoloho Rampai and it included an overview of Maris by Robyn Verrinder. The session was done in round table fashion and included posters and oral presentations. Tokoloho concluded the session with a closing statement

Over a period of 5 days 172 people participate in the 6th SANAP symposium. A lot has happened in the past 4 years since the last symposium in Hermanus in 2018 and feedback on research and other activities within SANAP featured on the program. The symposium was hosted by Stellenbosch University at Houw Hoek Hotel in the Grabouw valley where the participants built on a SANAP Research community for the future.
The Symposium kicked off with a hybrid meeting of the South African national committee for SCAR and the first evening a keynote lecture was presented by Prof Jukka Tukhuri (Aalto University, Finland) on the discovery of Shackleton’s Endurance on a voyage of the SA Agulhas II. During the symposium keynote lectures and plenary talks were given by Dr Peter Convey of British Antarctic Survey, Dr Sue Tonin of Mouse Free Marion and Prof Marcello Vichi on the Polar Lab part of the South African Polar Research Infrastructure (SAPRI).
The purpose of the symposium was to facilitate the free exchange of scientific information within SANAP research. In the Marine and Antarctic Research strategy it states that: “The need for coordinated, extensive and targeted research in the marine and oceanic domain has been underlined. Coordination has become important as there has been a shift in marine science from resources and process studies that could be carried out by small groups or individuals to very large-scale regional climate and ecosystem studies, where the success, nooses and benefits lie in the coordination.” One of the strategies outlined is: “creation of a society informed on the value of marine and Antarctic research initiatives.”
The following five thematic (vertical) areas were prioritised for research sessions and various principal investigators and researchers within SANAP chaired the sessions:
- Oceans and marine ecosystems under global change – Dr Rampai, Dr Fietz, Dr Thomalla, Dr Nicholson and Dr Lamont
- Earth systems observations – Prof Nel, Dr Lotz
- Ecosystems, biodiversity and biodiscovery – Prof Van Vuuren, Prof Cowan, Dr Greve, Prof Pistorius, Dr Wege,
- Innovation and development – Prof A Bekker
- Human Enterprise – Dr Lavery
Cross-cutting support interventions were discussed such as:
- Coordination and governance by Dr Gilbert Siko and Tracy Klarenbeek
- Human capital development and transformation chaired by Prof Ansorge
- Public awareness and engagement chaired by A Louw
- Research Infrastructure and platforms chaired by Dr T Morris
- Data management chaired by Dr Treasure
Feedback from SA National Committee for SCAR, APECSSA, SCALE expeditions and SEAmester were given and an evening session was held by the APECSSA committee where all the early career researchers that attended the symposium had great discussions. The newly established SAPRI was showcased to the SANAP community in cross discipline sessions on research infrastructure and platforms, data management and engagement, and a keynote lecture on the SAPRI Polar Lab that concluded all the research presentations
It was the first time that so many South African polar researchers were together on the 1st December on International Antarctic Day and a special Antarctic Breakfast took place to commemorate this International Day. A map of Antarctica, was signed and a cake was provided to celebrate the occasion.
The organising committee would like to thank all participants and attendees for making the 6th SANAP symposium a success and achieving its aim in building a SANAP research Community for the future. We are looking forward to the next Symposium in Kruger National Park in 2025 that will be hosted by a consortium of University of Johannesburg, Fort Hare University and the University of the Free State.
Comment by an ECR: “This was my very first SANAP symposium and it was absolutely incredible! Job well done to all those who assisted in organizing the event. Although it was a jam-packed week, the sessions were extremely interesting and well organized. The location was a perfect venue choice for this kind of event – especially for people to mingle, engage with one another and building strong relationships as well as for making connections for potential research collaborations. I am really impressed with the big focus that this symposium had on Early Career Researchers – I think it is a great way of getting the younger professionals more involved and to network! Congrats on pulling off a very successful SANAP Symposium!”
More will follow of the symposium and sessions that took place with a photos.
A huge thank you to the NRF for making the symposium possible and to all our suppliers and sponsors; Houw Hoek Hotel, Neelsie Travel Bureau, Adjuvo enterprises, Trilogy Audio Services, Crazylicous Cookies.

Research team on the recent Gough Island takeover expedition.

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.

The Gough Island Restoration Programme

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”.
