Snow Measurements in Specific Canopy Structure Regimes for the 2022-2023 Water Years, North of Coal Creek, San Juan Mountains, Colorado, USA

These data include snow depth and snow water equivalence (SWE) for the 2022 and 2023 water years during 16 separate field campaigns. The field area is comprised of 311 surveyed points in, on the perimeter of, and surrounding six forest openings next to Coal Creek off Coal Bank Pass in the San Juan Mountains in Southwest Colorado, USA. These measurements were taken to look at the relationship betwe

Model Archive Summary for Suspended-Sediment Concentration at USGS site 11502500, Williamson River below Sprague River near Chiloquin, OR

This model archive summary (MAS) is a model update to an existing log-transformed turbidity-suspended sediment concentration (SSC) regression model computing SSC for water year (WY) 2008-2017. This model supersedes all models prior to Oct 1, 2017 and includes a new model for WY 2018-2020. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (

Model Archive Summary for Suspended-Sediment Concentration at station 11501000, Sprague River near Chiloquin, OR WY 2008-2017 revision and computation for WY 2008-2020

This model archive summary (MAS) documents the revision of suspended sediment concentration (SSC) unit and daily values computed from WY 2008-2017, and the additional computation of SSC unit values from WY 2018-2020 using a new log-transformed regression model with SSC samples from the period of record at this site. The new, revised model computes SSC unit values for WY 2008-2020. This model super

Experimental Coral-Growth Data and Time-Series Imagery for Acropora palmata and Pseudodiploria strigosa in St. Croix, U.S. Virgin Islands

The U.S. Geological Survey Coral Reef Ecosystems Studies project (CREST) provides science that helps Department of Interior and other resource managers tasked with the stewardship of coral reef resources. This data release contains data on coral-growth rates and time-series photographs taken of colonies of the elkhorn coral, Acropora palmata, and the symmetrical brain coral, Pseudodiploria strigos

Grain size and charcoal abundance in sediment samples from Los Padres reservoir, Carmel River watershed, California

Sediment samples were collected from Los Padres reservoir in the Carmel River watershed, central California coast, between July 11 and 17, 2017, using a CME-45 barge-mounted drill rig, to characterize sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017. Borehole samples were recovered using direct push coring with an Osterberg p

Polycyclic aromatic hydrocarbon concentrations in soil, sediment, vegetation, and water samples collected from the Arctic National Wildlife Refuge during Summer 2019

This data set documents results of analysis of samples collected from the Arctic National Wildlife Refuge during Summer 2019. Data tables include: 1. The numeric and alphanumeric identifiers for samples collected for this study and the dates these samples were collected; 2. Results data containing concentration values of individual polycyclic aromatic hydrocarbon compounds in sediment, soil, and v

Electro-olfactory responses of Grass Carp, Bighead Carp, and Silver Carp to the amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid

Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmic

Uranium-Thorium Ages for Late Holocene Corals from the Southeast Florida Nearshore Ridge Complex

This data release compiles Uranium-Thorium (U-Th) dating data for late Holocene coral samples collected from the Nearshore Ridge Complex (NRC) off Pompano Beach, Southeast Florida (SEFL; Figure 1). The samples were collected under Scientific Activity Licenses (SAL) from the Florida Fish and Wildlife Conservation Commission (SAL-18-1659A-SRP) and with permission from Broward County Environmental Pr

Daily average soil moisture and ancillary data from the Noah land surface model in the National Land Data Assimilation version 2 extracted for GAGES-II watersheds, 1980 to 2020

This U.S Geological Survey data release contains soil moisture, actual evapotranspiration, precipitation, and potential evapotranspiration by watershed for the United States from 1980 to 2020. Hourly values from NASA's North American Land Data Assimilation System Phase 2 (NLDAS-2) Noah model were aggregated to daily values and extracted by Geospatial Attributes of Gages for Evaluating Streamflow,

Data showing similar movement ecology between mallards infected and not infected with highly pathogenic avian influenza H5N1

These data, which support a paired USGS publication, document the movement and infection status of mallards captured, marked, and tested at a wintering site in Tennessee. Data document differences in movement ecology between mallards infected and not infected with HPAI H5N1.

Phosphorus, nitrogen, carbon, calcium, pH, and dissolved oxygen data from incubations of Colorado River water and sediment and associated ambient river water measurements

Lake Powell retains most of the phosphorus that it receives, leading to downstream phosphorus limitation. These data were compiled to examine controls on phosphorus cycling below Lake Powell in the Colorado River and from storm inputs from the Paria River. Objectives of our study were to determine how several forms of phosphorus, both organic and inorganic, were cycled under varying dissolved oxyg

Streamflow projections for southwestern United States (1975-2099)

We projected future streamflow outcomes arising from climate change for the southwestern United States during the 21st century due to climate change under two possible greenhouse gas concentration pathways (RCP4.5 and 8.5). The results inform water managers about the future risks of drought in their water resource regions by providing bounds on the possible locations and extents of streamflow
