NOAA Regional Sea Level Trends and Scenarios
Abstract
NOAA has a new website to help coastal communities recognize past changes in regional sea level to better plan for a range of possible rise scenarios this century. The site compares 11 regionalized and coherent tide-gauge and satellite-altimeter sea level series from around the U.S. to estimate multi-decadal changes that have occurred in response to regional sea surface height-related trends and variability. Local relative trends are obtainable even without data from a local tide gauge when combined with estimates of vertical land motion, which can be obtained from several years of record from a GPS-based continuously operating reference system (CORS). The regionalized series will be updated annually and displayed relative to the most recent sea level rise scenarios of the (i.e., 2014) National Climate Assessment to characterize the regional sea level change trajectory for future planning of associated impacts.
