NCCOS Assessment: Sea Level Affecting Marshes Model (SLAMM) Habitat Projections in Plum Island Estuary (PIE), MA, 2040 to 2100 (NCEI Accession 0315948)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:26 AM | Dataset Last Updated: July 24, 2026 at 12:00 AM
This dataset contains spatial habitats projections for the years 2040, 2060, 2080, and 2100, generated by the Sea Level Affecting Marshes Model (SLAMM) for the Plum Island Estuary (PIE), Massachusetts. The raster data represent model projections of habitat classes resulting from an ensemble of inputs to account for both topographic and climate uncertainty. Topographic uncertainty was addressed via simulations run across three uncertainty-adjusted digital elevation models (DEMs representing the 20th, 40th, and 80th percentiles of elevation error) in addition to a baseline original DEM. Climate uncertainty was incorporated using three probabilistic relative sea-level rise (SLR) scenarios (Intermediate, Intermediate-High, and High), evaluating three statistical trajectories (17th, 50th, and 83rd percentiles) for the Monte Carlo DEMs, and the 50th percentile (median) trajectory for the baseline DEM. This data accession includes 120 total simulation results, each resulting from unique combinations of topographic uncertainty, climate scenarios, and time-steps. For example, the 40th percentile DEM paired with the 83rd percentile trajectory of the Int-High SLR scenario for the year 2080. The spatial resolution of the raster data is 3 meters, with results provided in 20-year intervals.
