Spatial heterogeneity of salt marsh vulnerability to sea-level rise: Dual controls of hydrological setting and salinity regime Spatial heterogeneity of salt marsh vulnerability to sea-level rise: Dual controls of hydrological setting and salinity regime
Salt marsh vulnerability to sea-level rise (SLR) is typically assessed using point measurements of vertical accretion, neglecting three-dimensionality of geomorphic evolution and spatial variability. Recent studies suggest links between vertical and horizontal vulnerability, with differences between oligohaline and polyhaline marshes, yet these relationships remain untested in estuary...

Compounding of 100-year coastal floods by rainfall in an urban environment Compounding of 100-year coastal floods by rainfall in an urban environment
Coastal and pluvial flooding are both becoming more prevalent and severe due to climate change and urbanization in floodplains. The co-occurrence of these flood drivers is generally assumed to exacerbate the resulting flood impacts, a result referred to as compound flooding. However, few observational or modeling studies have investigated the circumstances under which this occurs. Here...

Offshore Analysis of Seafloor Instability and Sediments (OASIS)
The Offshore Analysis of Seafloor Instability and Sediments (OASIS) project is an interagency partnership coordinated by the Bureau of Ocean Energy Management to better understand underwater mudslides and their impacts in the Mississippi River Delta Front. The USGS plays a central role in the project, contributing long-term expertise in coastal and marine geology, seafloor mapping, and geohazard...
American Samoa Mapping Project
USGS scientists are leading a sampling effort to the Samoan Basin, offshore of American Samoa. This work is part of an interagency supported three-month hydrograph survey project led by NOAA and in partnership with BOEM.
Digital Shoreline Analysis System (DSAS)
Software for calculating positional boundary change over time The Digital Shoreline Analysis System (DSAS) version 6 is a standalone application that calculates shoreline or boundary change over time. The GIS of a user’s choice is used to prepare the data for DSAS. Like previous versions, DSAS v.6 enables a user to calculate rate-of-change statistics from multiple historical shoreline positions...
