Loss of ice shelves removes a barrier to glaciers transporting water to the ocean, allowing sea levels to rise.
As ice shelves are afloat, any icebergs that form as a result of fractures in the ice do not contribute to sea level rise.
He joined more than 30 international scientists from different scientific fields and renowned organisations on the Weddell Sea Expedition, which is to attempt to locate and survey Sir Ernest Shackleton's lost ship Endurance, and increase understanding of Larsen-C, one of the largest ice shelves in Antarctica.
When ice shelves collapse, ice can flow faster from land into the sea, which can raise sea levels.
Led by Fernando Paolo, now a postdoctoral scholar at NASA's Jet Propulsion Laboratory but a PhD student at Scripps Institution of Oceanography at the University of California San Diego at the time of the study, the researchers found a strong El NiAaAaAeA~o caused "ice shelves in the Amunds Sea sector of West Antarctica to gain mass at the surface and melt from below at the same time, losing up to five times more ice from basal melting than they gain from increased snowfall."
The calving of ice shelves occurs naturally, though global warming is thought to have accelerated the process in some regions.
A chunk of ice the size of the US state of Delaware has broken off the Larsen C ice shelf, one of Antarctica's largest ice shelves. Scientists fear the shelf was destabilized by global warming.A 2,200-square-mile (5,800-square-kilometer) chunk of ice has separated from the Larsen C ice shelf.
The Larsen A and B ice shelves, which were situated further north on the Antarctic Peninsula, collapsed in 1995 and 2002, respectively.
Because the fragmentation and disintegration of ice shelves can influence sea levels by allowing land ice to flow into the ocean, "anything we can do to quantify what is going on with these large ice shelves is of huge importance," notes Godin.
Ice shelves are thick, floating platforms of ice that are connected to a landmass.
