Six Decades of Change at East Timbalier Island, Louisiana
July 28, 2020
Using ~ 1 m resolution imagery collected between 2000 and 2010, the U.S. Geological Survey (USGS) National Civil Applications Center (NCAC) monitored dramatic changes at East Timbalier Island, a Gulf of Mexico barrier island located on the west side of the Mississippi River Delta (Thomas et. al, 2011). The imagery was collected by US National Imagery Systems (USNIS) and archived at the USGS Global Fiducials Library (GFL). New research expands this study both retrospectively and prospectively using declassified imagery collected in 1962 and 1972; Landsat imagery collected since 1972; aerial photography collected since 1953; and 1991-2020 GFL imagery.
