As Sea Levels Rise, is the Ocean Floor Sinking?

A new paper in the journal Geophysical Research Letters suggests that redistribution of the total ocean mass from ice mass loss and land water storage is causing “the ocean bottom to subside elastically.”

A team of researchers from Delft University and the University of Tasmania used estimates of mass redistribution concluded that past estimates of sea level rise are too conservative and that to increase their accuracy, the effect of ocean bottom deformation should be taken into account, either based on modeled estimates of ocean mass change, or using more direct observations…

Present-day mass redistribution increases the total ocean mass and, on average, causes the ocean bottom to subside elastically…
