Twenty‐thousand‐year gap between deglaciation and peat formation on sub‐Antarctic Marion Island attributed to climate and sea level change

Radiocarbon dating of basal peats has been a key factor in determining minimum ages for deglaciation on sub‐Antarctic islands. On Marion Island, peat bogs dominate the landscape below 300m a.s.l., and palynological assessments of peat cores have been used to assess the vegetation history and succession rates as well as the sensitivity of the indigenous flora to climatic change. Initiation of peat on the sub‐Antarctic islands signifies a major landscape change which has previously been linked to the retreat of glaciers. Here we test this hypothesis by comparing previously published and new basal peat ages from Marion Island with cosmogenic isotope dates for deglaciation, and local and regional palaeo‐environmental changes. Results show that, in common with other sub‐Antarctic islands, peat initiation occurred after the Antarctic Cold Reversal (15–13 ka) and through the early Holocene climate optimum. This substantially postdates cosmogenic isotope evidence for deglaciation from the basalts which shows that the areas where the peatlands dominate were ice‐free from the start of Marine Isotope Stage (MIS) 2 (~31 ka). This suggests that environmental conditions controlled peat initiation rather than deglaciation. Regional climatic proxies show that during and after MIS 2, extremely low temperatures, extensive sea ice conditions and depressed sea surface temperatures together with lower sea levels at an island scale could have maintained conditions unfavourable for peat initiation at their current locations. On Marion Island, the significant gap of ~20 000 years between the timing of deglaciation and peat formation indicates that the use of peat basal ages as a proxy for the minimum age of deglaciation in the sub‐Antarctic should be used with extreme caution.

During the 6th SANAP symposium, time was allocated for the presentation of governance issues, and this was done on the first day during the opening ceremony. Dr Gilbert Siko , the Director of Marine & Polar Research at the Department of Science and Innovation gave the first presentation. His role within the Research Development and Support Programme it is to promote the development of research, the production of scientific knowledge, and human capital development in science areas in which South Africa enjoys a geographic advantage, that includes Antarctic and marine research. Dr Siko highlighted the strategic importance of the research conducted through the South African National Antarctic Programme.
Dr Siko was followed by Tracy Klarenbeek, Director of Knowledge Advancement and Support of the National Research Foundation (NRF). She highlighted that create innovative funding instruments such as SANAP serve to transform the scientific landscape and inspire a representative research community to aspire to global competitiveness. She shared the outcomes of the 2023 SANAP Call for Proposals for funding cycle 2024 – 2026 with the community. She also mentioned that mentorship initiatives for unsuccessful applicants would be implemented via SAPRI.(right)

Prof Bettine van Vuuren (right), Chair of the South African National Committee for SCAR gave feedback on the committee meeting. She also highlighted the function and activities of SCAR and the importance to be informed of these activities, and to be aware of scholarship opportunities. She encouraged early career researchers to become involved in SCAR committees and action scholarships.
The highlight of the Symposium was the international Antarctic day celebrations where Tracy Klarenbeek (left)addressed all attendees during the closing ceremony with a heartfelt talk. All participants, old and new, were thanked for their participation in the Symposium and their dedication to the SANAP programme. Tracy Klarenbeek talk gave a personal perspective of administering the SANAP programme:
“by facilitating Antarctic and Southern Ocean research, and awarding student bursaries, it is evident that the work I do changes lives”.
The opportunity to access the Southern Ocean, Antarctica and the sub-Antarctic islands (Gough and the Prince Edward Islands) is limited to the lucky few, and the work of the National Research Foundation makes this a reality for researchers and students alike.

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!”
