(Phys.org) —A trio of researchers (two from the University of Chicago, the other from Princeton) has proposed a new theory to explain the sudden breakup of the Larsen B Ice Shelf in 2002. In their paper published in Geophysical Research Letters, Alison Banwell, Douglas MacAyeal and Olga Sergienko suggest that the breakup came about due to the sudden drainage of one surface lake causing others to drain leading to a chain reaction that ultimately led to the entire ice shelf being torn apart.
