First expedition to newly exposed Antarctic ecosystem

A team of scientists, led by British Antarctic Survey (BAS), heads to Antarctica this week (14 February) to investigate a mysterious marine ecosystem that’s been hidden beneath an Antarctic ice shelf for up to 120,000 years.

 

The iceberg known as A-68, which is four times of London, calved off from the Larsen Ice Shelf in July 2017. The scientists will travel by ship to collect samples from the newly exposed seabed, which covers an area of around 5,818 km2.  It is an urgent mission.  The ecosystem that’s likely been hidden beneath the ice for thousands of years may change as sunlight starts to alter the surface layers of the sea.

While the team mobilises for the expedition, glaciologists and remote sensing specialists continue to monitor the movement of the Larsen C Ice Shelf.  In December 2017, a team from University of Leeds worked on the remaining ice shelf to investigate changes in ice structure after the calving event, to be able to predict shelf stability in the future.
