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

Using Video Imagery to Study Coastal Change: Madeira Beach, Florida

Video observations of Madeira Beach, Florida, are used to monitor a range of coastal processes, for example changes in the shoreline position, both seasonally and due to long-term effects such as sea-level rise, and instances of beach and dune erosion during extreme storm events.

USGS CoastCams

The U.S. Geological Survey (USGS) uses a nationwide network of coastal observing cameras, or CoastCams, to monitor coastal conditions in near real-time and support research by the USGS and its partners into a variety of coastal processes and hazards. The most recent CoastCam images are made publicly available within minutes of data collection and can be accessed using the links below or by...
