When an iceberg the size of Delaware separated from the Larsen C ice shelf last July, it uncovered an Antarctic marine habitat that had been concealed from the rest of the world for over 120,000 years, Quartz reports.
Now scientists are racing to study the 3,600 -square-mile ecosystem before it’s forever changed by its sudden exposure to sunlight. “The calving of -A6 8 provides us with a unique opportunity to study marine life as it responds to a dramatic environmental change, ” marine biologist Dr.
Katrin Linse tells the Guardian . -A6 8 is the trillion-ton iceberg–the largest in the world–that breach away from the ice shelf last summertime. Linse says it’s a “very exciting” opportunity for scientists, but they have to hasten because new species will rapidly enter the ecosystem now that it has been exposed to sunlight, USA Today reports.
British Antarctic Survey scientists led by Linse were scheduled to arrive in Antarctica on Wednesday. Over the next three weeks they’ll explore 2,200 square miles of the newly exposed region while observing marine mammals and birds near the surface and taking samples of microbes and other life at the seafloor.
It won’t be easy. The average temperature in the area is 15 degrees, and it’s full of large hunks of ocean ice. But David Vaughan, science director at the British Antarctic Survey, says analyse the area is important for learning about the potential impacts of climate change on Antarctica.
“How fast species can disperse, and how fast ecosystems can colonize new areas, is key to understanding where the Antarctic is likely to be resilient, and where it is vulnerable, ” he tells the Guardian .
