This dataset is one of a number of datasets containing geomorphological data relating to the Windmill Islands, Wilkes Land, Antarctica. The dataset comprises a digital line coverage representing contour boundaries defining the marine incursion limits. The contour boundary information is linked to a separate digital database (ie attribute table). Interpretation of these boundaries can be carried ... out using sediment samples collected predominantly along the shoreline of these lakes. They represent a chronology of glacial events/influences on these lakes. Sediment samples taken as a profiled sequence or core can be dated using radiocarbon dating to provide a chronological picture and age occurance of deglaciation and glaciation cycles within the Windmill Islands.
These data were compiled by Dr Ian D Goodwin from his own field notes and from the records of other workers. See the linked document at the URL below for further information.
