This data set contains a grid representing Holocene marine sediment thickness (in meters) on the inner continental shelf offshore of Fire Island, New York. Approximately 2200 line kilometers of chirp sub-bottom data collected with an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz) during USGS survey 2011-005-FA, were analyzed to produce this surface. The Holocene sediment thickness (isopach) is used in assessing relationships between geologic framework, sea-bed morphology, and sediment textural trends.

|Data format:||WinZip file (version 14.0) contains three Esri grids (and associated metadata) that define the Holocene sediment thickness (in meters, fi_hiso), the elevation of the Holocene transgressive surface (NAVD88, fi_hts) and the elevation of the coastal plain unconformity beneath the inner-continental shelf offshore of Fire Island, NY (NAVD88, fi_cpun). The zip file also contains layer files (.lyr) to aid in display of the data within ArcGIS. in format AIG (version ArcGIS 9.3.1) Esri Raster GRID format Size: 1.6|
These data are available as a ArcInfo 32-bit floating point binary grid in Esri format. The floating point binary grid and associated 'info' folder are stored in one folder 'seismic' that has been compressed using WinZip (ver. 14.0) software. To utilize these data, the user must have software capable of uncompressing the zip file and importing and viewing an Esri ArcRaster grid. The zip file also contains associated metadata.
