Direct measurements of ice-shelf flexure caused by surface meltwater ponding and drainage

Meltwater ponding on top of ice shelves is thought to play a role in ice-shelf flexure and fracture, however in-situ evidence of these mechanisms is lacking. Here, the authors provide field-based evidence showing the impact of the filling and draining of four surface lakes on ice-shelf flexure in An...

Sumario:Meltwater ponding on top of ice shelves is thought to play a role in ice-shelf flexure and fracture, however in-situ evidence of these mechanisms is lacking. Here, the authors provide field-based evidence showing the impact of the filling and draining of four surface lakes on ice-shelf flexure in Antarctica.
