The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

Limestone salamanders (Hydromantes brunus) are cryptic terrestrial salamanders about which little is known, including their distribution. Because the salamanders are difficult to detect, survey protocols that estimate detection probabilities are needed to interpret the meaning of negative (non-detection) surveys and better understand the distribution of the salamanders. This study...

This dataset includes measurements of biological and physical attributes of five restored tidal wetlands in the San Francisco Bay Estuary. All marshes were restored in the last 30 years, from the late 1990's to the early 2010's, and are located between San Pablo Bay in the north to the South Bay Salt Ponds in the south. Biological attributes measured include plant species presence...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Pohnpei State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Chuuk State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Kosrae State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

This dataset consists of one table containing whole-rock geochemistry data for 748 rocks from southcentral Alaska. All materials in the present study were analyzed by ALS Global between 2014 and 2022 using a range of different techniques, so multiple unique entries for a given element relate to different analytical methods or preparations, as detailed in accompanying metadata, and...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Bossier Formation within the Onshore United States and State Waters of the Gulf Coast Region. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

Surface sediment samples were collected from the Samoan Basin, an abyssal region in the Pacific Ocean on expedition 2026-604-FA. This region is within the U.S. Exclusive Economic Zone (EEZ) offshore American Samoa. These samples were analyzed by portable X-ray fluorometry (XRF) to measure geochemical concentrations of major, minor, and some trace elements to determine if there was any...

This dataset contains six csv files representing timeseries survivorship, before and after stress testing results, and metabolomics data from a reciprocal transplant experiment using two species of coral, Montipora capitata and Porites compressa. Data were collected from 2023 to 2025 on the Windward side of Oʻahu, Hawaii with coral being transplanted to and from two bays, Kailua Bay and...

This model application data release contains seasonal source-specific estimates of total nitrogen (TN) and total phosphorus (TP) loading in streams across the conterminous United States (263,494 reaches) for 21 years from 2000 through 2020 using a dynamic SPARROW (SPAtially Referenced Regressions On Watershed attributes) model. All model files are provided to reproduce the output...
