Fire Island National Seashore Sediment Grain Size and CMECS Classification Data

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2017-04-19T00:00:00Z
Sediment Grain Size and CMECS Classification Data used to construct benthic habitat maps for FIIS. The ground-truth surveys involved the collection of surficial grab samples of the seafloor, sediment profile imagery (SPI), and underwater video. The three instruments were deployed together, allowing for co-located datasets. Combined, these datasets help provide a thorough understanding of the study areas, as they capture sediment and biological community characteristics at various spatial scales and resolutions.
