Matthieu Tordeur and Heïdi Sevestre are embarking on an extraordinary 4000-kilometre expedition across Antarctica to collect data that could provide crucial insights into the future of the continent in a warming world. Their journey began on 3 November, as they skied towards a small mound in the vast white expanse, only to discover a golden head emerging from the snow – the bust of Vladimir Lenin left by a Soviet expedition at the southern pole of inaccessibility, the point in Antarctica furthest from any coast.
This surreal encounter marked the beginning of a groundbreaking kite-ski expedition, the first of its kind to collect data for polar science. Using kites that can pull them at speeds of 35 kilometres an hour or more, Tordeur and Sevestre are hauling sleds equipped with ground-penetrating radar capable of scanning the snow and ice up to 40 metres deep.
The primary objective of their expedition is to investigate whether increased snowfall in the interior of East Antarctica is offsetting greater melting along the coast. While satellite measurements provide some insight, the data collected by Tordeur and Sevestre could lead to more accurate estimates, according to Martin Siegert from the University of Exeter.
With no one in sight for a thousand kilometres in all directions, the duo is venturing into uncharted territory to gather essential information that could help scientists better understand the dynamics of Antarctica’s ice sheet. Their findings may have far-reaching implications for future climate projections and sea level rise.
From towing a more powerful radar capable of penetrating 2 kilometres deep to tracing ancient ice layers from East Antarctica into West Antarctica, Tordeur and Sevestre are pushing the boundaries of polar research. The British Antarctic Survey is particularly interested in their work, as it could shed light on the stability of West Antarctica’s ice sheet, a region with the potential to raise sea levels by up to 5 metres.
Despite facing numerous challenges, including navigating through sastrugi and enduring extreme temperatures, Tordeur and Sevestre remain steadfast in their mission. Sevestre finds solace in listening to audiobooks during their journey, drawing inspiration from the resilience of early explorers who braved the harsh Antarctic conditions.
As they ski towards Hercules Inlet in West Antarctica, the clock is ticking. They have three months to complete their expedition before the Antarctic summer ends and all flights out of the continent cease. With determination and a spirit of adventure, Tordeur and Sevestre are paving the way for groundbreaking research that could shape our understanding of Antarctica’s future.
