Warm water melts weak spots on Antarctica's 'Doomsday Glacier'
Thwaites - nicknamed the Doomsday Glacier - which is roughly the size of Florida, represents more than half a meter of global sea level rise potential, and could destabilise neighbouring glaciers that have the potential to cause a further three-meter rise.
Researchers found that warmer water was making its way into crevasses and other openings known as terraces, causing sideways melt of 30 meters or more per year. Using an underwater robot vehicle known as Icefin, monitoring data and censors, they monitored the glacier's grounding line, where ice slides off the glacier and meets the ocean for the first time.
