This model archive summary (MAS) and associated model calibration dataset documents the suspended-sediment concentration (SSC) model developed to compute 15-minute, near-real-time SSC at U.S. Geological Survey (USGS) streamgage station 06329500, Yellowstone River near Sidney, Montana (MT) for calendar years 2022-2024 and is the model currently in use. This model is specific to USGS site...

This model archive summary (MAS) and associated model calibration dataset documents the suspended-sediment concentration (SSC) model developed to compute 15-minute, near-real-time SSC at U.S. Geological Survey (USGS) streamgage station 06329500, Yellowstone River near Sidney, Montana (MT) for calendar years 2017-2021. This model is specific to USGS site 06329500, Yellowstone River near...

This dataset contains data from a capture-mark-recapture survey of four species of native treefrogs across four sites in Bayou Teche National Wildlife Refuge, Louisiana.

This dataset contains results of generalized least-squares (GLS) regression for 63 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia. This dataset was created to support the Washington D.C. StreamStats project funded by the Washington D.C...

This data release provides annual values for the 19 standard bioclimatic variables (BIO1–BIO19) for the Contiguous United States, computed from the downscaled CMIP6-LOCA2 temperature and precipitation dataset for 1950–2100. Daily maximum temperature, minimum temperature, and precipitation from 27 CMIP6-LOCA2 GCMs were processed using the Python xclim library to generate bioclimatic...

This data release contains paleoecological records from Santa Fe Lake, NM USA. Santa Fe Lake is a small (1.4 ha), subalpine lake in the Sangre de Cristo Mountain Range of the Southern Rocky Mountains (35.79°N, 105.78°W, 3532 m a.s.l). Overlapping sediment cores were taken from Santa Fe Lake in September, 2020 in 5.4 m of water from a coring platform with a Livingstone square-rod piston...

Regressions were developed to predict Escherichia coli (E. coli) concentrations at four U.S. Geological Survey (USGS) gages on streams in Chester and Delaware Counties in southeastern Pennsylvania. The regression analysis was based on 2019-24 discrete E. coli concentrations measured in samples collected approximately monthly by USGS from April to October and concurrent available...

Low-level stratiform clouds modulate California's coastal climate during the warm season. Previous work describing the seasonal and daily variability of coastal low cloudiness (CLC) suggests that in July, August, and September southern California's CLC is under the influence of an additional driver, which has less impact in northern California. In this work, we introduce the link in...

As part of a collaborative study with the City of Raleigh, the U.S. Geological Survey developed this dataset to characterize streambank erosion and channel incision throughout Raleigh, North Carolina. This dataset includes 8 shapefiles that describe the study subbasins, drainage network buffer, channels, channel buffers, channel segments, channel segment buffers, in-field stream-walk...

This dataset consists of 3-component acceleration timeseries that describe ground shaking from simulated Mw6.5+ earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults in Washington State. These were produced in support of the development of simulation-based scenario ShakeMaps, as described in Stone et al. (2026). Individual scenarios span a variety of different source...

We measured soil CO2 fluxes on grids with the accumulation chamber method on July 15-17, 2021, September 10, 2022, and May 6-7, 2025, at Mud Volcano, an acid-sulfate, vapor-dominated area in Yellowstone National Park, WY. We also monitored variations in CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half-hourly basis from...

These data were collected as part of the USGS Sierra Nevada Forest Dynamics Study. They include tree mortality data from 30 plots located along an elevational gradient in the Sierra Nevada of California from 1982 to 2019. Although the data were collected annually, for purposes of compatibility with a global analysis, they were abstracted to five-year census intervals.
