Multiple cosmogenic nuclides document complex Pleistocene exposure history of glacial drifts in Terra Nova Bay (northern Victoria Land, Antarctica)
Geomorphological and glacial geological surveys and multiple cosmogenic nuclide analyses ((10)Be, (26)Al, and (21)Ne) allowed Lis to reconstruct the chronology of variations prior to the last glacial maximum of the East Antarctic Ice Sheet (EAIS) and valley glaciers in the Terra Nova Bay region.
