内容記述 |
At sites where glacio-isostatic rebound has occurred, the record of sea-level change can be used to infer the former ice thickness and its melting history At Mt Riiser-Larsen, former sea-levels higher than present are indicated by the presence of raised beach deposits and ancient sediments deposited in brackish water Sediment cores from three ice-marginal lakes contained only fresh-water sediment, and a basal radiocarbon age shows that there has been no marine incursion in the last ~10000 years, limiting sea-level during that time to lower than 18 4m above present A well-defined marine limit is present 15 m a s 1, which will be dated using radiocarbon ages on stranded seals and abandoned penguin rookeries We anticipate an age of ~6 ka, because of the interaction between eustatic and isostatic components of sea-level change |
