Atlas of Observed Sea Level ChangeUSACE Releases the Atlas of Observed Sea Level Change, Version 1

The U.S. Army Corps of Engineers (USACE) has created version 1 of an Atlas of Observed Sea Level Change to present basic data on how sea level is changing. This data is presented with screenshots from the USACE Sea Level Tracker Tool.  USACE plans to update this document periodically so that data on changing sea level is up to date and easily available for nontechnical users to understand.

This Atlas presents data from National Atmospheric and Oceanic Administration (NOAA) tide gauges located in the following regions:  Atlantic Ocean, Gulf Coast, Caribbean, Pacific Coast, and Pacific Islands. In this initial version of the Atlas, data for each NOAA tide gauge is presented using the same three screenshots from the USACE Sea Level Tracker tool:  (1) a screenshot displaying the mean sea level midpoint moving average e over a 19-year period and a 5-year period, (2) a screenshot that builds on the first graph to add monthly averages, and finally (3) a final third screenshot that zooms in on screenshot #2 to look at only the fifty year period between January 1980 and January 2030.  The Atlas is available in both high resolution and low resolution.
