Antarctica’s ‘Doomsday Glacier’ keeps scientists at bay with iceberg and sea ice

Attempts to study the deteriorating Florida-sized glacier that could raise sea levels by 2ft if it breaks off are being frustrated

Antarctica's so-called Doomsday Glacier, nicknamed because it is huge and coming apart, is thwarting an international effort to figure out how dangerously vulnerable it is.

A large iceberg has broken off the deteriorating Thwaites glacier and, along with sea ice, it is blocking two research ships with dozens of scientists from examining how fast its crucial ice shelf is falling apart.
