Antarctic Peninsula ice more stable than previously thought

Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported.

Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported.

An international team of researchers, led by the UK Centre for Polar Observation and Modelling at the University of Leeds, is the first to map the change in ice speed. The team collated measurements recorded by five different satellites to track changes in the speed of more than 30 glaciers since 1992.

The findings, published today in Geophysical Research Letters, represent the first detailed assessment of changing glacier flow in Western Palmer Land — the southwestern corner of the Antarctic Peninsula.

The new Leeds-led research calls into question a recent study from the University of Bristol that reported a 45 cubic kilometres per year increase in ice loss from the sector. The Leeds research found the increase to be three times smaller.
