Aeromagnetic Survey - Regional Data
Listed in NASA Earthdata CMR
The British Antarctic Survey (BAS) began regional aeromagnetic surveys over the Antarctic Peninsula in 1973.
Description
The first four seasons up to 1980, together with supplementary data from subsequent seasons, provided 36 000 line km of data " north of 72 degrees S. The survey was extended southwards over southern Palmer Land and Ellsworth Land during 1986. Since 1980, activity has been concentrated farther south.
In 1983, data were collected over the Ronne Ice Shelf as part of the BAS Weddell Province Project to investigate the relationship between East and West Antarctica. Two seasons have been completed with US logistical support during the joint BAS-United States Antarctic Research Programme (USARP) project investigating the structure and tectonic history of the area. As part of this work, data were collected from the area of the Ellsworth and Thiel mountains during 1984.

Ellsworth Land, the Ellsworth Mountains and Bryan coast were covered during the final survey in 1987. Metadata records for each survey are available by following the Related_URL link to the BAS data catalogue.
