Data

A Cessna 182 fixed-wing aircraft equipped with a multispectral camera was used to collect aerial imagery of selected river reaches within the Willamette River Integrated Water Science basin in Oregon. On April 16-18, 2024, image acquisition was focused on four reaches of the Clackamas River. Photogrammetry techniques were applied to the images consisting of visible or red, green, and...

We used data from 2.5 years of A. canadensis observations in the San Luis Valley to examine their foraging patterns during spring and autumn migration. We counted cranes weekly or bi-weekly each season and year during roadside surveys. We determined crop type (alfalfa, barley, pasture, potatoes, other grain, and other) during roadside surveys. We also recorded tillage intensity for grain...

Sediment accumulation and transport negatively affect flood control, water supply, aquatic life, reclamation, and recreation (Angino and O’Brien, 1968) and are concerns of resource managers in the Kankakee River Basin of northern Indiana and throughout many regions of the United States. By relating continuously monitored water-quality data to discrete data collected from April 2016...

This archive contains results of lagrangian particle-tracking (LPT) simulations of both the dispersal of rhodamine dye and larval drift. The LPT model is a research effort and the simulations here provide some of the first experimental validation of the results for dispersal of a conservative constituent (Rhodamine WT-20). The larval drift simulations however have not been validated and...

This data release supports "Diverging trends in nitrate and phosphorus loads and yields across Illinois watersheds, 1997–2022" (Kamrath and others, 2024) and the State of Illinois's Nutrient Loss Reduction Strategy (NLRS; Illinois Environmental Protection Agency [IEPA] and others, 2015). This data release contains estimates of incremental nitrate (NO3) and total phosphorus (TP) loads and...

Data includes monthly-average projected changes to climate for a 23-member ensemble of CMIP6 SSP2-4.5 GCMs downscaled using NASA’s Land Information System. Average snow outputs are generated using these climate projections for 20-year periods between 2016 and 2095. More information on this data, and comparisons versus various community snow projections in mountainous regions can be found...

The impacts of five proposed restoration alternatives at Little Dauphin Island, Alabama (AL) were assessed using process-based numerical models to simulate annual scale sediment transport and storm-driven morphological change. The five restoration alternatives include a no-action scenario representing a continuous island (R0), a tidal inlet channel realignment (R1), a sand spit (sand...

As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Breton Island, Louisiana (LA). During this study, multibeam bathymetry and acoustic backscatter data were collected...

We evaluated potential effects of deltamethrin and fipronil on tiger salamander (Ambystoma mavortium) body mass, behavioral activity, and insecticide tissue residues. Insecticides were applied at realistic concentrations in mesocosms mimicking prairie dog burrows, which are used as refuge by salamanders under natural conditions. Treatments included (1) deltamethrin dust, (2) prairie dog...

This dataset consists of a complete set of audio recordings collected near a large walrus haulout at Point Lay, Alaska, during September of 2024. The recordings were collected using the Song Meter Mini 2 (Wildlife Acoustics, Inc., Maynard, MA) at two sites, one within 150 m of a large walrus herd resting on shore and one placed more than 4 km to the south of the herd directly under the...

This dataset contains water level, water temperature, and vegetation data from 12 locations within the Nisqually River Delta, Washington from 2010 to 2015. This dataset was part of a larger monitoring effort to document hydrological and vegetation changes throughout the Nisqually River Delta following large scale estuarine restoration (dike removal) in 2009.

A suite of tables filled with greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) survival data and environmental covariate values, extracted to sage-grouse nest, brood, and general locations, as well as lek locations. We quantified 8 indicators of temperature and/or moisture conditions across time spans representing lags of 0-1.5 years, while accounting for other...
