Published by ORNL_DAAC | National Aeronautics and Space Administration | Metadata Last Checked: January 03, 2026 | Last Modified: 2025-12-30

This dataset provides global salt marsh change, including loss and gain for five-year periods from 2000-2019. Loss and gain at a 30 m spatial resolution were estimated with Normalized Difference Vegetation Index (NDVI) anomaly algorithm using Landsat 5, 7, and 8 collections within the known extent of salt marshes. The data are provided in cloud-optimized GeoTIFF format.
