Sea level 400 000 years ago (MIS 11): analogue for present and future sea-level
School of Earth and Ocean Sciences, Cardiff University, Cardiff, CF10 3YE, UK
Abstract. Comparison of sea-levels today and 400 000 years ago (MIS 11), when the Earth's orbital characteristics were similar, may provide indications of future sea-level during the present interglacial. Evidence for former sea-levels occur on uplifting coastlines where shorelines are preserved. The sea-level term and the uplift term may be separated with an "uplift uplift correction" formula. This discovers the original sea-level at which the uplifted shoreline was fashioned. Estimates are based on average uplift rates of the "last interglacial" sea-level (MIS 5.5) using a range estimates for sea-level and age at that time and at different locations. These, with varying secular tectonic regimes in different ocean basins, provide a band of estimates for MIS 11. They show the MIS 11 sea-level was close to its present level and Greenland and West Antarctic ice volumes were similar to present.
