All Data

High-resolution chirp sub-bottom data were collected by the U.S. Geological Survey, Pacific Coastal and Marine Science Center in May of 2019 in Whiskeytown Lake, California using an Edgetech SB-512i sub-bottom profiler. These data were collected to measure possible debris flows into the lake during the 2018-2019 rainy season following the July-August 2018 Carr fire that burned vegetation...

In 2019 the magnesium-to-calcium (Mg/Ca) ratios were measured in the tests of planktic foraminiferal species, Globigerinoides ruber (white variety), in a subset of samples from Integrated Ocean Drilling Program (IODP) sediment core U1146 from the Bay of Bengal drilled November 2014 to January 2015. For further information regarding data collection and/or processing methods, refer to the...

A three-dimensional hydrodynamic and sediment transport model of San Pablo and Suisun Bays was constructed using the Delft3D4 (D3D) modeling suite (Deltares, 2021a) to simulate water levels, flow, waves, and suspended sediment for time period of Nov 1 to Dec 31, 2014. This data release describes the construction and validation of the model application and provides input files suitable to...

Data supporting the article, "Nutrient limitation of benthic algae in streams: integrating laboratory bioassays, field experiments, and field data." Datasets include from a battery of laboratory and in situ nutrient limitation tests in streams in the upper Snake River basin, Idaho. Nutrient limitation bioassays of stream water used the green algae Pseudokirchneriella subcapitata...

The dataset contains GPS survey data collected at Colorado River at Salt Wash near Moab, UT, as part of a surface velocity mapping effort. The survey was conducted on October 6, 2020, and documents ground control points for a small unmanned aircraft system (sUAS) survey. The survey was performed using Leica GS14 RTK GPS equipment, S/N base-2806898, S/N rover-2806883.

Several Francisella spp. including F. noatunensis are regarded as important emerging pathogens of wild and farmed fish. However, very few studies have investigated the virulence factors that allow these bacterial species to be pathogenic in fish. The Francisella Pathogenicity Island (FPI) is a well-described, gene-dense region encoding major virulence factors for the genus Francisella...

The video shows a short animation of river flow dynamics (flow velocity vectors) over multiple tidal cycles.

Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. This data release includes videos of debris-flows and floods captured by high-definition cameras placed at four...

The data presented include concentrations of 10 metals in sediments and composite larval amphibian tissues from 20 wetlands across the United States. Sixteen of the wetlands were sampled in 2019 and four were sampled in 2015-2016. Where possible both larval anurans (frogs and toads) and salamanders were collected from each wetland. The data also include information on metal...

This data release includes climatic variables and associated descriptive material created for the purpose of assessing uncertainties associated with climatic estimates based on vegetation assemblages (Thompson and others, 2021). The data are from the interior of the western United States, including all of Arizona, and portions of California, Colorado, Nevada, New Mexico, Texas, and Utah...

These data provide a comprehensive survey of peak-stage indicators along the Colorado River corridor between river mile (RM) 0 and RM 87 (see Figure 1 in the associated USGS-SIR). In 2008, the locations of peak-stage indicators in three short reaches downstream from RM 87 were measured using a handheld GPS unit (see Appendix 1 in the associated USGS-SIR). Total-station measurements were...

We used an automated radio telemetry network to track the movement of two nectivorous Hawaiian honeycreepers, the 'Apapane (Himatione sanguinea) and 'I'iwi (Drepanis coccinea), collecting high temporal and spatial resolution data across the annual cycle. We identify movement syndromes using a multivariate analysis of multiple movement metrics and assessed seasonal changes in movement...
