Observations and morphodynamic modeling of decadal-scale morphologic change in estuaries under sea level rise

Sea level rise is expected to affect coastal areas all around the world, including the estuarine environment. New bathymetry collected in 2014 provided a unique opportunity to test the modeling of Elmilady et al. (2019), who presented a morphodynamic DELFT3D model of San Pablo Bay, California, that included detailed tidal water movement, wind-wave action, sediment transport, and resulting bed leve

Abundance and distribution of large thecosome pteropods in the northern Gulf of Mexico

The ecological role of large thecosome pteropods in the pelagic ecosystem of the northern Gulf of Mexico (GoM) may be substantial, both in the food web and biogeochemical cycling. We analyzed species abundances, vertical and horizontal distributions of large species with calcareous shells (those collected in 3-mm mesh nets). Pteropod samples were collected following the 2010 Deepwater Horizon oil

Biofilms as potential reservoirs of stony coral tissue loss disease

Since 2014, corals throughout Florida’s Coral Reef have been plagued by an epizootic of unknown etiology, colloquially termed stony coral tissue loss disease (SCTLD). Although in Florida the movement of this waterborne coral disease has been consistent with natural transport via water currents, outbreaks in the Caribbean have been more sporadic, with infections occurring in locations inconsistent

SENHIC Project Milestones and Meetings

As part of the Stakeholder Engagement for Natural Hazards Investigations in the Caribbean (SENHIC) project, the USGS team aims to connect with scientists who are conducting natural hazards research in the Caribbean, build relationships with natural hazards researchers based in the Caribbean and those specializing in the region, and develop a framework for collaborating with international partners.

Digital Shoreline Analysis System (DSAS)

Computer Software for Calculating Shoreline Change (or positional change of a boundary over time) The Digital Shoreline Analysis System (DSAS) v5 software is an add-in to Esri ArcGIS desktop (10.4-10.7+) that enables a user to calculate rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing measurement locations, performs rate...
