Analysis of the effect of Hurricane Sandy on New Jersey Atlantic coastal marshes based on landsat thematic mapper and operational land imager data: 2000-2015

February 27, 2017

This USGS Data Release represents geospatial data sets that were created for the analysis of the effect of Hurricane Sandy on New Jersey Atlantic Coastal Marshes. The following listed image products were generated:

1) Fifteen marsh surface condition index (MSCI) data sets were calculated from yearly summer collections of ETM+ image data from 2000 to 2015. Three classes described the results of the MSCI mapping; classs1-severely impacted, class 2-moderately impacted, and class 3-intact marsh.
2) Marsh change data product using Landsat images of July 14, 2011 (before) and July 19, 2013 (after) Hurricane Sandy is based on the difference in the percentage of vegetation. It shows a pattern of an increasing loss of marsh vegetation for the marshes closest to where Sandy made landfall near Brigantine, New Jersey.
3) Land cover classification using Landsat TM of 14 July 2011 and 19 July 2013, 30 m spatial resolution. Eleven classes namely i) high salt marsh ii) estuarine high salt marsh iii) forested wetland iv) Phragmites australis and Spartina cynosuroides v) salt shrub scrub vi) marsh substrate from estuarine marsh area vii) marsh substrate located near lagoon viii) unconsolidated beach sediment ix) ponds and other shallow bodies on marsh x) small tidal creeks xi) urban development areas
