Bentley Shot Holes

General Information

The Bentley Shot Hole cores collected in 1994 and 1995 were cores of opportunity as the result of geophysical studies in central West Antarctica. Four cores ranging in depths between 50 to 90 meters were collected. The sites lie on a 200 km traverse gaining elevation from 950 to 1930 meters. The Bentley Shot Hole cores are referred to as Central West Antarctica (CWA) cores in the Reusch and others (1999) paper. Some cores have a continuous archive remaining.
