Land loss in coastal Louisiana since 1932

 

Every year, 25-35 square miles of land off the coast of Louisiana—an area larger than Manhattan–disappears into the water due to a combination of subsidence (soil settling) and global sea level rise. The maps above show how much land has been lost to the Gulf of Mexico in the past 80 years.

 

The first image shows the state of the coast in 2011. Based on a NASA satellite image, gray and white areas show land and blue indicates open water. New land—mainly coastal improvements such as shoreline revetments and enriched beach areas—that built up since 1932 is shown in green.
