Baseline information on both the modern processes operating on Antarctic beaches and the development of beach ridges in relation to the last glaciation ice retreat and isostatic rebound

Where possible profiles were surveyed to benchmarks which were linked to sea level via the tide gauge at Cape Roberts. These were a starting point to run a GPS base station to give approximate locations for each surface exposure sample site, site of each hole dug and other significant points. To resolve the surveys for mean sea level, lag times from Cape Roberts to various locations along the coast were calculated from tidal measurements taken at Cape Bernacchi and Cape Bird.

The tidal curve constructed from these data was compared with the observed tidal data for Cape Roberts. Offshore surveys were also undertaken at Marble Point, Cape Royds and Cape Bird. In addition to surveying profiles, pits were excavated so that the stratigraphy and sedimentology of the beaches could be examined.

Pits were located on survey profiles so they could be related to each other. Pits were described, measured and samples were removed for size analysis. The beach processes were observed in action including the effects of waves and ice when the sea ice has broken up and out.

Optically stimulated luminescence samples were collected at Cape Bernacchi, Marble Point, Kolich Point, Spike Cape and Cape Barne. These require sandy material that has been sunlight, then been buried, such as in beach ridges in order to date sediment exposure.
