Report cards show continued sea-level rise on East & Gulf coasts

These web-based charts—available online at www.vims.edu/sealevelreportcard—project sea level out to the year 2050 based on an ongoing analysis of tide-gauge records for 32 localities along the U.S. coastline from Maine to Alaska.
The lead on the project, VIMS emeritus professor John Boon, says the report cards add value by providing sea-level projections that are updated more frequently than those issued by NOAA or other agencies.
Boon and colleagues also use a statistical approach that includes evidence for recent acceleration in the rate of sea-level change at many U.S. tide-gauge stations, and stress their use of relative sea-level measurements—changes in water level relative to the land surface on which people live and work. The relative sea-level rise in Virginia and other East and Gulf coast areas is due to both rising water and sinking land.
This year’s report cards, updated using monthly summaries of daily tide gauge records from calendar year 2018, show that trends in sea-level change generally held steady across the 32 stations, although the processes that control sea level fluctuated slightly from region to region. Release of this year’s cards was delayed by the 35-day government shutdown, which precluded compilation of and access to NOAA’s latest tide-gauge records.
