Abstract
Geological evidence and oxygen-isotope variations in deep-sea cores provide valuable information about the sea-level variations of the past. Ice-volume equivalent is usually computed by using a constant oceanic area. In this paper a relationship is developed between the continental ice-volume variation and the sea-level drop by taking into account the sea-floor topography and, therefore, the variation of the oceanic area. It appears from such calculations that the last glacial maximum ice volume is 7% less than previously estimated, and that the minimal reconstruction of the ice sheets from Hughes et al. (1981) seems the most likely.
