Our coasts, the most familiar part of the ocean are the gateway to the larger deeper ocean world. USGS studies processes and hazards in the coastal zone and how they affect people, wildlife, and ecosystems.

In June 2022, Mendenhall Fellow Sabine Loos (Research Civil Engineer in the Geological Hazards Science Center) presented a seminar to USGS's Earthquake Science Center at Moffett Field, CA, where Max Schneider (Research Statistician) works as a Mendenhall Fellow.

Rich Briggs and Alex Hatem make geologic observations within Nevada’s Monte Cristo Range, June, 2022.

Researchers from the USGS, NASA, and NAU gather around a small simple esker and ephemeral lake deposits.  The team used sedimentology, geochemistry, and remote sensing to characterize these features on Earth before comparing them to Mars.

An erosion model activity used by the St. Petersburg Coastal and Marine Science Center to showcase how hurricane-force winds can cause damage to coastal environments.

The USGS Coastal Change Hazards Portal contains an interactive map of historical shoreline positions and shoreline change rates for Puerto Rico.

Close-up oblique views of Mount Rainier’s west side showing simulated lahar flow depths from a landslide originating in the area of the Tahoma Glacier Headwall (T-260-HM simulation). Imagery appears blurry where lahar material is absent because D-Claw’s adaptive mesh refinement (AMR) employs very coarse resolution in those areas.

Fault sections being used in the creation of the 2023 U.S. Seismic Hazard Maps. Blue lines are normal faults, yellow lines are reverse faults, and red lines are strike-slip faults.

Noa Randall and Rachel Allen are installing an optical turbidity sensor on the mudflats in Wellfleet harbor, to pair with the altimeter run by the Center for Coastal Studies.  The Herring River, which drains into Wellfleet Harbor, is slated to have its 100-yo dam removed in the next 6 months, with the potential to dramatically increase the sediment load and sus

Looking over the dunes towards the beach in the Otis Pike Fire Island High Dune Wilderness at Fire Island, New York. 

Scientists collected sand auger cores from Fire Island to help reconstruct the evolution of the barrier over the last several centuries, with the goal of quantifying changes in sediment input and partitioning through time (e.g., how sand is distributed between the terrestrial portion of the barrier and the beach/shoreface).

The USGS Puerto Rico Landslide Susceptibility Map provides an interactive tool to assess landslide risk in Puerto Rico from low susceptibility to extremely high.

The USGS National Water Dashboard provides real-time stream, lake, reservoir, precipitation, water quality and groundwater station in context with current weather and hazard conditions.

The USGS Latest Earthquakes Map provides is an interactive tool that provides detailed information about the latest earthquakes worldwide.

In collaboration with the National Park Service, Woods Hole Oceanographic Institution, and the Vesta Corporation, the Environmental Geosciences group researched a new approach to climate change mitigation. The team led an experiment at the Herring River site as a first examination.
