Abstract

Seismic experiments conducted on ice stream B, part of the marine ice sheet of West Antarctica, show a meters-thick layer immediately beneath the 1000-m thick ice. Very low wave speeds imply that the material in the layer is highly porous and is saturated with water at a high pore pressure. -from Authors
