Summary
Abstract: Limited exposure is a major drawback when using drillcores for
reconstructing past glacial environments: direct observations of
sediments are restricted to the width of the cores and only provide a
scattered view of former 'depositional situations'. Still, in
offshore settings like the Antarctic continental shelf, drillcores are
often the most valuable sources of information available. It is
