Florida corals are bleaching due to high water temperatures
As much of the world grapples with historic heat waves exacerbated by climate change and the ongoing El Nino event, ocean temperatures are also on the rise.

Testing megathrust rupture models using tsunami deposits
The 26 January 1700 CE Cascadia subduction zone earthquake ruptured much of the plate boundary and generated a tsunami that deposited sand in coastal marshes from northern California to Vancouver Island. Although the depositional record of tsunami inundation is extensive in some of these marshes, few sites have been investigated in enough detail to map the inland extent of sand deposition and depi
Tropical or extratropical cyclones: What drives the compound flood hazard, impact, and risk for the United States Southeast Atlantic coast?
Subtropical coastlines are impacted by both tropical and extratropical cyclones. While both may lead to substantial damage to coastal communities, it is difficult to determine the contribution of tropical cyclones to coastal flooding relative to that of extratropical cyclones. We conduct a large-scale flood hazard and impact assessment across the subtropical Southeast Atlantic Coast of the United
Forecasting storm-induced coastal flooding for 21st century sea-level rise scenarios in the Hawaiian, Mariana, and American Samoan Islands
Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding in the populated Hawaiian, Mariana, and American Samoan Islands as a result of climate change and sea-level rise. We followed a hybrid (dynamical and statistical) downscaling approach to map flooding due to waves and storm surge at 10-square me

Post-Fire Sediment Research at the Pacific Coastal and Marine Science Center
The USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, has been growing our post-fire research contributions since 2017, through studies of post-fire sediment movement that address the Natural Hazards Mission Area objectives for understanding wildfire hazards.
Anthropogenic Nutrient Loading and Coral Health at Ofu, American Samoa
Declining water quality poses a significant and persistent threat to coral reefs worldwide, contributing to their widespread degradation. Identifying the specific impacts of water quality stressors is challenging due to the complex interplay of various physical and biological factors affecting reef health. Submarine groundwater discharge (SGD) plays a crucial role in transporting nutrients into...
Developing a USGS Digital Coral Growth Archive using Rotating X-Ray Computerized Tomography - The ACTS Project
The Archival Computed Tomography Scanning Project (ACTS) currently develops the USGS Coral Core Archive, housed at the Pacific and St. Petersburg Coastal and Marine Science Centers, that contains approximately 500 coral reef cores from U.S. jurisdictions worldwide. This archive, is one of the largest coral archives in the world and provides historical context for coral-reef science studies...
