Rapid Response Seafloor Seismology
Ocean-bottom seismographs are valuable tools for studying marine geohazards like subduction zone earthquakes. The USGS has partnered with the Woods Hole Oceanographic Institution to operate a small fleet of highly mobile instruments to deploy during periods of seismic unrest.
2024 Hurricane Season
USGS news on tropical storms and hurricanes throughout the 2024 hurricane season.
New Tool Revolutionizes Coastal Shoreline Mapping with Decades of Satellite Data
Coastal scientists and resource managers have long sought a reliable and efficient way to monitor and manage the world’s shorelines. Thanks to extensive collections of satellite data spanning more than four decades, this endeavor is now more feasible.
Preparing the Nation for Coastal Hazards
USGS provides emergency responders, resource managers, and communities with the science they need to safeguard lives, infrastructure, and resources along the coast
Underwater Photogrammetry Reaches New Depths
The USGS developed a workflow for creating 3D models of the deep seafloor from archived video images. The study, “Photogrammetry of the Deep Seafloor from Archived Unmanned Submersible Exploration Dives,” was recently published in the Journal of Marine Science and Engineering.
Uncovering 14,000 Years of Seismic Activity in Northern Cascadia
New USGS research documents a 14,000-year history of seismic activity preserved in the sediments of Ozette Lake, a ~100-meter (328-foot) deep coastal lake on Washington State's Olympic Peninsula. The study provides crucial insights into the long-term seismic behavior of the northern Cascadia subduction zone, one of the most tectonically active regions in North America.
Restoring Coral Reefs for Coastal Hazard Risk Reduction in the U.S. Virgin Islands
A new study from the University of California, Santa Cruz, The Nature Conservancy, and USGS quantifies the social and economic benefits that coral reefs provide to the coastal communities of the United States Virgin Islands (USVI).
The Coastal Science Navigator Companion Guide
The Coastal Science Navigator Companion Guide is now available. It highlights 64 USGS coastal change hazards-related products in total.
Effects of Climate Variability on Coastal Erosion in the Pacific Northwest
New research finds that subtle shifts in wave direction, driven by multi-annual climate variability, are causing significant patterns in coastal erosion and sediment deposition along the Pacific Northwest coastline. The findings demonstrate how engineered coastal structures like jetties can intensify these natural processes, with potentially far-reaching implications for coastal management.
Benthic Invertebrate Response to Estuarine Marsh Restoration at the Nisqually River Delta
New research from the U.S. Geological Survey and the U.S. Fish and Wildlife Service evaluates the response of benthic invertebrates to the largest estuary and tidal marsh restoration project in the Pacific Northwest at Washington’s Nisqually River Delta.
Deep-Sea Mining and Potential Impacts on Marine Ecosystems: New Study Highlights Geochemical Implications
Marine polymetallic nodules, also known as manganese (Mn) nodules, have attracted the interest of mining companies for decades due to their enrichment of metals such as cobalt (Co), nickel (Ni), copper (Cu), and rare earth elements (REEs).
