Coastal and Marine Hazards and Resources Program
Scientists and staff study coastal and ocean processes, from shorelines to the deep sea, to identify hazards and provide critical information on our nation's resources. This work supports preparedness, emergency response, and the protection of people and resources in coastal and ocean environments.

Geologic framework and Holocene sand thickness offshore of Seven Mile Island, New Jersey
The U.S. Geological Survey assessed the Quaternary evolution of Seven Mile Island, New Jersey, to quantify coastal sediment availability, which is crucial for establishing sediment budgets, understanding sediment dispersal, and managing coastlines. This report presents preliminary interpretations of seismic profiles, maps of Holocene sand thickness from the shoreline to 2 kilometers...
Shoreline seasonality of California’s beaches
We report on remote sensing techniques developed to characterize seasonal shoreline cycles from satellite-derived shoreline measurements. These techniques are applied to 22-yr of shoreline measurements for over 777 km of beach along California's 1,700-km coast, for which the general understanding is that shorelines exhibit winter-narrow and summer-recovery seasonality. We find that...
Coral reef restoration can reduce coastal contamination and pollution hazards
Coral reef restoration can reduce the wave-driven flooding for coastal communities. However, this protection has yet to be assessed in terms of the reduced risk of flood-driven environmental contamination. Here we provide the first high-resolution valuation of the reduction of flood-related land-based environmental pollution provided by potential coral reef restoration. Along Florida’s...

APPROACH (APplying Proxy-based Reconstruction Of Atlantic Climate CHange)
USGS scientists use marine geological archives to investigate how ocean temperature, salinity and circulation patterns changed over the past few centuries to millennia. This is done by analyzing the geochemical and physical clues about past environments that are preserved in fossil coral skeletons, clam shells, foraminifera and marine sediments.
Cultural Heritage at Risk Tool (CHART) Project
Coastal erosion threatens the loss of Native American cultural heritage and archaeological sites located along our coastlines, reducing opportunities to increase knowledge of past communities and environments. This project leverages an advisory team of ancestral Tribes, coastal managers, and archaeologists to strengthen the effectiveness of coastal hazard data, focusing on assessing the...
Antibiotic-Resistance Gene (ARG) Baselines
On Florida and Caribbean coral reefs, stony coral tissue loss disease (SCTLD) has caused widespread destruction and loss of coral cover since its first appearance off the coast of Miami in 2014. So far, the only intervention found to be effective at halting progression of this disease and saving the lives of infected coral colonies is applying an amoxicillin paste, a type of antibiotic, to the...
