Description
Summary:In 1999, the National Oceanic and Atmospheric Administration-National Marine Fisheries Service and the State of Louisiana jointly undertook the restoration of East Timbalier, a barrier island along a sediment-starved portion of the Gulf of Mexico coast of Louisiana. High-resolution overhead imagery was used to monitor the course of this restoration effort. This article describes the changes in area and movement of East Timbalier Island and compares these changes with the previous measurements. Between 2000 and 2010, East Timbalier Island lost 52-66% of its area and moved northwards 12-105 m/year. The area of East Timbalier Island is less today than at any time since 1887. Understanding of the physical processes in nature that control the size, shape and movement of the island, as well as the human impacts that have hastened its degradation, is critical for accomplishing any future restoration.
