The Duration: Life and Science on the Fimbulisen Ice Shelf
Through mid- and late January, the team balanced demanding science with the realities of Antarctic fieldwork. GNSS stations positioned around major basal crevasses provided precise measurements of ice motion and fracture growth, helping assess the risk of large calving events. Complementary radar surveys quantified changes in ice thickness, supplying key inputs for ice-shelf flow models.
Seismic surveys used arrays of geophones and controlled energy sources to image the ice shelf and the ice–ocean interface. Drone-based ground-penetrating radar revealed the structure and evolution of deep basal crevasses, building on data from the previous season.
Fieldwork was frequently interrupted by severe storms, including wind gusts exceeding 120 km/h. Despite delays, the team adapted schedules and used downtime for maintenance and data checks. A major milestone was the first deployment of SAR corner reflectors on an Antarctic ice shelf, enabling highly accurate satellite tracking of ice motion.
Together, these measurements produced a unique dataset capturing both surface and subsurface behaviour of the Fimbulisen Ice Shelf.

Monitoring Antarctic Ice Shelf Stability. Antarctic ice shelves play a critical role in controlling future sea-level rise.
In January 2026, an international research team began the second field campaign of Structural Glaciological Analysis of the Antarctic Ice Shelves, supported by the National Research Foundation and the South African National Antarctic Programme (SANAP). Led by the University of Cape Town’s Polar Engineering Research Group, the project combines expertise in engineering, geophysics, and glaciology.
The focus is the western Fimbulisen Ice Shelf , which regulates ice flow from the Antarctic interior into the Southern Ocean via the Jutulstraumen Glacier. Changes in its stability directly affect ice discharge and global sea level.
The SANAP 2025/2026 team arrived aboard SA Agulhas II on 11 January 2026 and established a field camp on the ice shelf. Early work centred on retrieving data from permanent GNSS stations and phase-sensitive radar instruments measuring ice motion, thickness, and basal melt.
These efforts marked the start of five intensive weeks of fieldwork aimed at understanding how Antarctic ice shelves respond to a warming climate.

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.
This project is funded by: The National Research Foundation, South African National Antarctic Programme funding (NRF-SANAP).

The Biogeochemistry Research Infrastructure Platform (BIOGRIP) was established in 2019 in terms of the South African Research Infrastructure Roadmap, a high-level research strategy of the national government Department of Science and Innovation.
BIOGRIP comprises four research ‘nodes’ based at the Universities of Cape Town (focusing on isotope biogeochemistry), Stellenbosch (water and soil biogeochemistry), Free State (mineral biogeochemistry) and North-West University (atmospheric biogeochemistry), with the administrative ‘hub’ located at UCT. The Director will be based at UCT and will report directly to the DVC Research. The Director will (1) provide strong leadership and scientific guidance to the BIOGRIP platform as a whole, ensuring that it delivers on its mandate (2) liaise with stakeholders, the management steering committee and scientific and technical advisory committees (3) hold overall financial responsibility for BIOGRIP and (4) contribute to the research output of BIOGRIP.
“Biogeochemistry” is the study of how biological, geological, chemical, and physical processes interact to shape natural environments over time and space. It covers a range of interdisciplinary research foci, from the origin and diversification of life, to how anthropogenic drivers alter modern environments, to the response of natural systems to environmental change. Biogeochemistry was identified by the 2016 South African Research Infrastructure Roadmap (SARIR) document as an emerging interdisciplinary field of strategic importance. SARIR recommends that the central objective of biogeochemical research in South Africa should be to gain “further insight into the interactions of human activity and the environment over the past several hundred millennia and to determine how the environmental impact of anthropogenic activity has contributed to the change in Earth system dynamics (chemical, physical and biological). This includes the search for an understanding of the behavior of well characterized and emerging pollutants and their current impact on the environment”. There are a number of strong research groups in South Africa already investigating various aspects of this broad research objective, but their efforts to-date have been isolated and/or fragmented. Moreover, biogeochemistry requires high precision data and measurements of a vast range of inorganic and organic chemical components, including isotope ratios and trace elements, some of which cannot currently be made in South Africa and many of which cannot be run at the volume and quality required. The investment in BIOGRIP will provide the platform to drive biogeochemical knowledge creation through investment in (1) technical capacity, training and scientific leadership in biogeochemical research, (2) world-class analytical facilities, and (3) improved monitoring of biogeochemical environmental variables through the generation and compilation of statistically meaningful datasets.
BIOGRIP will provide significant opportunities to advance South Africa’s research infrastructure and technical capacity in the field of biogeochemistry, while also facilitating a high level of scientific impact on a range of temporal and spatial scales. BIOGRIP will extend the practical research questions that address specific South African problems to include those that are purely curiosity-driven, creative, and/or risky, while also deepening the extent to which ongoing research themes can be probed. An additional impact of developing analytical capacity in-country is the potential for creative methods development, particularly South African-specific applications (e.g., for research questions relevant to the Cape floristic kingdom, hominin evolution, water availability and quality, Antarctic ecosystems, etc.). This will allow the South African research community to push the frontiers of knowledge in a variety of fields where biogeochemical techniques have yet to be applied (or have yet to be applied at the resolution offered by BIOGRIP).
