Pockmarks offshore Big Sur, California provide evidence for recurrent, regional, and unconfined sediment gravity flows
Recent surface ship multibeam surveys of the Sur Pockmark Field, offshore Central California, reveal >5,000 pockmarks in an area that is slated to host a wind farm, between 500- and 1,500-m water depth. Extensive fieldwork was conducted to characterize the seafloor environment and its recent geologic history, including visual observations with remotely operated vehicles, sediment core sampling, an
Evidence on the ecological and physical effects of built structures in shallow, tropical coral reefs: A systematic map
Shallow, tropical coral reefs face compounding threats from climate change, habitat degradation due to coastal development and pollution, impacts from storms and sea-level rise, and pulse disturbances like blast fishing, mining, dredging, and ship groundings that reduce reef height and complexity. One approach toward restoring coral reef physical structure from such impacts is deploying built stru
Late-Quaternary surface displacements on accretionary wedge splay faults in the Cascadia Subduction Zone: Implications for megathrust rupture
Because splay faults branch at a steep dip angle from the plate-boundary décollement in an accretionary wedge, their coseismic displacement can potentially result in larger tsunamis with distinct characteristics compared to megathrust-only fault ruptures, posing an enhanced hazard to coastal communities. Elsewhere, there is evidence of coseismic slip on splay faults during many of the largest subd

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...
Alaska Flood Staffs
The U.S. Geological Survey (USGS) uses observations of flooding in communities to monitor hazard conditions and support research by the USGS and its partners into a variety of hazard processes in Alaska. Local observations of flooding at a flood staffs are used to document flood elevations, improve flood models, and support floodplain management decisions.
