To further extend the scope of the Science Application for Risk Reduction (SAFRR) project, detailed hydrodynamic simulations were run at three harbor locations in California. For the locations of 1) Oakland/Alameda, 2) Half Moon Bay, and 3) Santa Cruz, simulations at approximately 5-m resolution were performed using the high-order Boussinesq-type model COULWAVE. The Oakland/Richmond simulation are

This page contains results from analysis of 2020 Maacama earthquake sequence, including the detected and relocated earthquake catalog along with associated focal mechanisms and preferred fault planes as derived in: Shelly, D. R., R. J. Skoumal, and J. L. Hardebeck, Fracture-mesh faulting in the swarm-like 2020 Maacama sequence revealed by high-precision earthquake detection, location, and focal m

The Southern San Andreas fault (SSAF) poses one of the largest seismic risks in California. However, structural properties around Coachella Valley remain enigmatic. In 2019, we collected magnetotelluric soundings (MT) to help inform depth-dependent fault zone geometry, fluid content and porosity. This project was led by the Institute of Geophysics and Planetary Physics at the University of Califor

We analyzed morphological and molecular data from one existing and one newly discovered population of 'bullseye' snakehead (Teleostei: Channidae) from Florida. Morphological and meristic data were collected from museum collections and compared with data from recent taxonomic revisions of related species in the 'Marulius' species group from southeast Asia. Additionally, we performed DNA sequencing

This dataset is part of the National Water Census ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of total flow and snowmelt for each hydrologic unit are added to the already released estimates of actual evapotranspiration, snowpack water-equivalent storage, soil moisture, recharge, strea

Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey Landsat Burned Area product was used to identify burned area across CONUS over a 39-year period (1984-2022). The Landsat BA product was consolidated into a suite of annual BA product

Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in June of 1999 in the coastal zone and continental shelf between Los Angeles and San Diego, offshore California (USGS field activity O-1-99-SC). In 2021 these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin.

A data release containing information on benthic macroinvertebrate communities and sediment toxicity in the Eighteenmile Creek Area of Concern and a nearby reference area at Oak Orchard Creek. Bed sediments were collected during summer 2021 at 8 sites on Eighteenmile Creek and at 6 sites on Oak Orchard Creek using a petite Ponar dredge for macroinvertebrate identification and sediment toxicity tes

These data are related to surveys of eelgrass beds in Norma Bay, Izembek Lagoon, Alaska. The table provides eelgrass shoot lengths and density measurements from sampling in September 1987.

This data release presents part of historical fisheries-dependent data for Cisco (Coregonus artedi) in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron collected by scientists from U.S. Geological Survey's Great Lakes Science Center, including three tables for monthly Cisco-catch and fishing-effort data and two tables for biological data of Cisco individuals. The monthly Cisco-catch and fi

This data release consist of the annual sediment depositional volume at five floodplain and five point bar sites on Powder River in southeastern Montana from 1979 through 2017. These 10 sites are a subgroup of a larger group of cross-sections established in 1975 and 1977 to monitor the channel changes along a 90-kilometer reach of Powder River. In addition to the sediment deposition data, characte
