Critter-finding mission to Antarctica’s Larsen C iceberg scrapped
Too much ice prevented the research vessel from reaching the calving site
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.
