PAIS: The Sound of a Community Effort

“Every contribution matters.” Anybody who ever played in a sport team probably heard this sentence at some point. Actually, this is completely true also as far as science is concerned. Whereas in the collective imagination science is about big discoveries made by a single genius, the truth is that great science is made little by little, step by step. Science is a community effort in which every contribution matters. And that is the concept from which this video was born.

SCAR Scientific Research Programme PAIS

The SCAR Scientific Research Programme PAIS (Past Antarctic Ice Sheet dynamics) aims to improve understanding of the sensitivity of East, West, and Antarctic Peninsula Ice Sheets to a broad range of climatic and oceanic conditions.

PAIS builds on the success of SCAR-ACE (Antarctic Climate Evolution), but with a new focus on the ice sheet rather than palaeoclimate reconstructions. Study intervals span a range of timescales, including past "greenhouse" climates warmer than today, and times of more recent warming and ice sheet retreat during glacial terminations.

A new ice core record provides clues on the evolution of the ice sheet in the Wedell sea during the last glacial termination which could improve the understanding of the ice-ocean-atmosphere feedback for climate change projection.

Scientific report by C.J. Fogwill, et al

Ice sheets dynamics is closely related to climate change and sea-level rise. Still, several mechanisms are involved in the ice-climate feedback, which are not accurately represented by global climate models so far. This hampers the predictions of the Antarctic ice sheet response to climate change in the future. In this study, Fogwill et al. present climate records obtained from an new, 800m long, ‘horizontal ice core’ in the Weddell Sea Embayment (Antarctica). The horizontal record is obtained in an ice stream, hence, going upstream enables to go back 50,000 years. The record covers the last glacial termination and thus enables the study of ice sheet dynamics during the largest climatic transition. During the last glacial termination, long-term warming is not monotonous and a 2 000 years long cooling occurred in Antarctica and in the Southern Ocean, known as the Antarctic Cold Reversal. Interestingly, during this period, the climatic record obtained in the Weddell Sea Embayment shows an important warming which denotes from other records across Antarctica. Here, the warming is associated with a local decrease in ice sheet elevation, and thus related to significant ice mass loss in the Weddell Sea Embayment. This observation is seconded by indices of a large number of icebergs in the area during the Antarctic Cold Reversal.

The red arrow highlights the apparent ice sheet surface elevation change across the Weddell Sea Embayment using this record for the Antarctic Cold Reversal (ACR) period (blue shaded area). The black triangles are age tie points. This record, combined with marine geological evidence of enhanced iceberg calving and modelling of the ice sheet during the climatic transition provides the first direct evidence of the high sensitivity of the Antarctic ice sheet to global ice-ocean-atmosphere feedback while the Antarctic climate remained cold. The modelling approach even generalise the results to the entire Antarctic ice sheet margin and provide a better representation of the ice-ocean-atmosphere feedback to improve sea level projections.
