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.

Programme: Space Science: Volunteer
This is a unique opportunity for individuals with a scientific and/or engineering background, who are eager for an extraordinary experience in a remote Antarctic environment. We are currently assembling a team to participate in the annual relief expedition to SANAE IV, Antarctica. The SANAE IV station in Antarctica lies at 71°S, 2°W – 4280 km from East Pier in Cape Town Harbour. (Photo above taken in 2022 during the annual relief voyage)
Successful candidates will embark on the SA Agulhas II, South Africa’s polar research and supply vessel, for a voyage of approximately 14 days to Antarctica. Upon arrival, they will be stationed at the SANAE IV research base for the entire relief period. Volunteers will work under the guidance of the Group Leader/Senior Engineer, assisting with critical infrastructure maintenance, scientific instrument servicing, and logistical operations during the expedition.
Voyage Dates: 9 December 2025 – 9 February 2026 (TBC)

Another session within the Marine and Antarctic Research Strategy research theme : Innovation and engineering was chaired by Annie Bekker of the Sound and Vibration Group (SVG) at Stellenbosch university. This was an evening session done in a round table format and included international speakers from Finland. Prof Bekker gave an overview of the research and the sessions format tool on a round table/panel discussion. (Picture: Presenters of the session at the venue)

An initiative by Mia Wege was to use the SANAP symposium to bring all “bio loggers/trackers” together, that included researchers who tag animals, mostly top predators across the globe. The purpose was to get some structure going and talk about a potential larger workshop specifically for the entire community. The meeting was well represented, and this was a great opportunity used.
Two of the Principal investigators of the project were able to attend the symposium. ( Nico de Bruyn(left) – University of Pretoria and Jaco Versfeld (Right) Stellenbosch University)
