Abstract:
Given the climatic similarity between the last interglacial (LIG) period (ca. 125 ka ago) and climate model projections for the near future, the reconstruction of eustatic sea level (ESL) in the LIG period is relevant for understanding future sea level change in in the context of global warming. Age (using uranium and thorium isotopic analysis) and elevation data for fossil corals from this time period in the circumCaribbean region are not consistent with relative sea level predictions from glaciohydroisostatic modeling, indicating that modifications need to be made to the existing ice model, specifically for the last and penultimate glacial maxima. To determine which of these ice sheet models needs adjusting, elevations of two coeval stratigraphic horizons within the fossil reef were surveyed on San Salvador and Great Inagua. The result demonstrates a minimal gradient in elevation between the sites and a rate of sea level rise that is significantly lower than the model predictions. This indicates that the penultimate glacial Laurentide ice sheet needs to be reduced and some adjustment to the last glacial maximum Laurentide ice sheet may also be required to bring the model into agreement with the observational data.
