| Summary: | <p>Estimating the contribution of marine ice sheets to sea-level rise is
complicated by ice grounded below sea level that is replaced by ocean water
when melted. The common approach is to only consider the ice volume above
floatation, defined as the volume of ice to be removed from an ice column to
become afloat. With isostatic adjustment of the bedrock and external
sea-level forcing that is not a result of mass changes of the ice sheet
under consideration, this approach breaks down, because ice volume above
floatation can be modified without actual changes in the sea-level
contribution. We discuss a consistent and generalised approach for
estimating the sea-level contribution from marine ice sheets.</p> |
