Abstract
Land cover on the Mississippi–Alabama barrier islands was surveyed in 2010–2011 as part of continuing research on island geomorphic and vegetation dynamics following the 2005 impact of Hurricane Katrina. Results of the survey include sub-meter GPS location, a listing of dominant vegetation species and field photographs recorded at 375 sampling locations distributed among Cat, West Ship, East Ship, Horn, Sand, Petit Bois and Dauphin Islands. The survey was conducted in a period of intensive remote sensing data acquisition over the northern Gulf of Mexico by federal, state and commercial organizations in response to the 2010 Macondo Well (Deepwater Horizon) oil spill. The data are useful in providing ground reference information for thematic classification of remotely-sensed imagery, and a record of land cover which may be used in future research.
Highlights
The data described were collected in a May 2010, through July 2011, field survey that recorded land cover features on Cat, West and East Ship, Horn, Sand and Petit Bois Islands in Mississippi and western and central Dauphin Island in Alabama, U.S.A., northern Gulf of Mexico (Figure 1)
Island geomorphic features were substantially altered by erosion and sand overwash [2,3,4,5,6,7], while vegetation was further affected by wind damage, salt spray, saltwater flooding and a post-storm drought of several months [6,7]
Prior to the 2010–2011 field survey, the Gulf shorelines of Ship, Horn and Petit Bois Islands were eroded in Hurricane Gustav on 1 September 2008 [8]
