GPS survey of 11 points for the David Glacier and its Drygalski Ice Tongue
Entry ID: GPS_David_Glacier

Abstract: Drygalski Ice Tongue is the largest ice tongue in Ross Sea. It is 70 kilometers
long (43.4 miles) and 20 kilometers wide (12.4 miles) and drains David Glacier.
This ice tongue is large enough to show up on maps of the Antarctic continent.
Drygalski Ice Tongue has been growing seaward 150 to 900 meters per year (492
to 2952 feet) for the past few decades.
