Thick sea ice has thwarted researchers’ plans to explore what creatures lived beneath an Antarctic ice shelf. A mission to study seafloor life suddenly exposed by the breaking away of the Larsen C iceberg last July was delayed as it tried to navigate through floating ice, some chunks as thick as 5 meters. With 400 kilometers still to go, the captain of the vessel, the RRS James Clark Ross, canceled the mission February 28.
“It was nature [that] defeated us,” said principal investigator and marine biologist Katrin Linse of the British Antarctic Survey in Cambridge in a video released by BAS March 2. “We knew this mission was high risk and high reward.”
Not all is lost, though. The vessel is now heading to the nearby Larsen A ice shelf, where an iceberg broke away in 1995. There, researchers will study a never-explored deep-sea seafloor ecosystem 1,000 meters beneath the ocean’s surface.
Linse will have another opportunity to visit Larsen C, however. She’ll join a 2019 expedition led by the Alfred Wegener Institute in Bremerhaven, Germany.
