Using Satellite Measurements to Improve Regional Estimates of the Impacts of Sea Level Change.

Changes in sea level already impact coastal communities through erosion, storm surge, saltwater intrusion, and other effects. Projections of future rise have even more dramatic implications, with relatively small rises potentially displacing millions of people. Though the sources of sea level rise are generally known, the specific details of steric and nonsteric contributions are poorly constrained, as is the regional variability that is subject to a myriad of influences, such as ocean currents, lithospheric motions, and global gravitational effects.
