The Mid-Atlantic Resource Imaging Experiment (MATRIX)
In late August 2018, scientists and technical staff from the USGS Coastal/Marine Hazards and Resources Program completed the acquisition of over 2000 km of multichannel seismic (MCS) data as part of the Mid-Atlantic Resource Imaging Experiment (MATRIX) conducted aboard the...

Sediment Transport in Coastal Environments
Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to...
Significant Earthquakes on a major fault system in Hispaniola, Puerto Rico, the Virgin Islands, and the Lesser Antilles, 1500–2010: Implications for Seismic Hazard
Earthquakes have been documented in the northeastern Caribbean since the arrival of Columbus to the Americas; written accounts of these felt earthquakes exist in various parts of the world. To better understand the earthquake cycle in the Caribbean, the records of earthquakes in earlier catalogs and historical documents from various archives, which are now available online, were critically...
Coastal Model Applications and Field Measurements- Advances in Instrumentation
Ongoing acquisition of new instruments and development of analytical methods provides us with the means to make better observations of coastal ocean processes. The measurements provide us with insight and data for critical evaluation of model performance. Advances in a range of measurement capabilities, including bottom stress, sediment erodibility, water properties and nutrient concentrations...
Coastal Model Applications and Field Measurements- Ocean Model Contributions
The U.S. Geological Survey (USGS) and Woods Hole Oceanographic Institution (WHOI) led a project funded by the National Oceanographic Partnership Program (NOPP) with support from the Office of Naval Research (ONR) and the National Science Foundation (NSF), to develop a community sediment-transport modeling system (CSTMS).

IMMeRSS-- Interagency Mission for Methane Research on Seafloor Seeps
From May 3 to May 11, 2017, the U.S. Geological Survey, in collaboration with the British Geological Survey and with support from these two agencies, the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration and Research, and the U.S. Department of Energy, will lead an...
Preliminary Landslide Susceptibility Maps and Data for Hawaii
Landslide Susceptibility Data and Maps provide tools for hazard assessment prior to an event that may cause landslides.
Gas Hydrates- Submarine Slope Destabilization
USGS scientists have a long tradition of studying submarine slope failures and were among the first to note a spatial link between slope failures and gas hydrates/gas-charged sediments. USGS Gas Hydrates scientists support the USGS Hazards Mission area through field-based surveys that refine understanding of this association and through geotechnical studies that evaluate the response of...
Gas Hydrates- Atlantic Margin Methane Seeps
Analysis of 94,000 square kilometers of multibeam water column backscatter data collected by the NOAA Okeanos Explorer mostly seaward of the shelf-break on the northern US Atlantic margin reveals more than 570 gas plumes that correspond to seafloor methane seeps. This discovery is documented in an August 2014 ...
Caribbean Tsunami and Earthquake Hazards Studies
Puerto Rico and the Virgin Islands are located at an active plate boundary between the North American plate and the northeast corner of the Caribbean plate. Plate movements have caused large magnitude earthquakes and devastating tsunamis, but scientists have so far failed to explain the deformation of this complex region in a coherent and predictable picture, and this has hampered their...
