Pacific Northwest Avian Scavenger Lead and Mercury Dataset, 2012-2016

The dataset includes the bird species, region where sampled, sampling site, capture location, mercury concentration in whole blood, lead concentration in whole blood, sulfur stable isotope concentration in blood plasma, carbon isotope concentration in blood plasma, whole blood ALAD activity, and fecal corticosterone concentrations.

Habitat diversity and longitudinal connectivity limit the functional diversity and redundancy of fishes in a large river: Data

The csv file includes all individual non-young-of-year fishes collected in unstructured channel borders of the Upper Mississippi River using daytime electrofishing from 1993 through 2015, following LTRM protocols. Data was collected via the Long Term Resource Monitoring element of the U.S. Army Corps of Engineers Upper Mississippi River Restoration program and the Illinois Natural History Surveys

Plant production responses to precipitation differ along an elevation gradient and are enhanced under extremes (Northern Arizona, 1991-2016)

This dataset is from a precipitation manipulation experiment conducted at five grassland sites along an elevation gradient near Flagstaff, AZ. The data consist of pre- (1991 - 2010, 2015) and post-experimental (2016) treatment plant production and precipitation measurements. The plant production measurements were taken from satellite and hand-held spectroradiometer, in addition to plot-based harve

Groundwater-Surface Water Interactions in Ellerbe Creek in Durham, North Carolina, 2016-2018

A hydrologic study involving the investigation of groundwater-surface water interactions along Ellerbe Creek, a major tributary to upper Falls Lake, was conducted in order to determine if groundwater is a likely source of nitrate input to the stream. Groundwater-surface water interactions were characterized by synoptic streamflow measurements, groundwater-level monitoring, hydrograph-separation me

High-Resolution Aeromagnetic Survey of Mountain Pass, California

A detailed aeromagnetic survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG) during November and December, 2016. The high-resolution helicopter survey was flown at a flightline spacing of 100 and 200 m, a flightline azimuthal direction of 70 degrees, a nominal flightline elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at

Sleeping Bear Dunes National Lakeshore qPCR Data. Collection Year: 2012

This environmental dataset consists of 56 sediment, 24 Cladophora and 22 water samples collected from beaches at Glen Haven, Good Harbor, Platte Bay and Esch road beach, located within The Sleeping Bear Dunes National Lakeshore, Leelanau and Benzie counties, Michigan. The dataset includes matrix type, location, data, time and the qPCR reported value for each sample collected.

Watershed potential erosion rate ranking system and check-dam placement suitability data within the Southern Rockies Landscape Conservation Cooperative (SRLCC)

Using Natural Resource Conservation Service (NRCS) soil databases, topographic features derived from digital elevation models, stream networks, and regional climatic patterns, I developed a ranking system for watershed potential erosion rates and suitability for check-dam placement across the SRLCC. This ranking system serves as a first step for land managers to prioritize areas for check-dam inst

Spatial predictions of habitat suitability for present-day (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) time intervals

This dataset provides spatial predictions of habitat suitability for current (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) intervals using hindcasting, and three separate paleo-distributions calibrated on the packrat midden archive: those without bias correction (naive), those created with a standard method (standard), and those created with a novel alternative (modeled) incorporating a thre

Remotely sensed variables analyzed and reported in the paper titled "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape condi

The comma-delimited fields in this dataset provide values for the remotely sensed variables analyzed for landscape blocks described in the paper, "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions," by Sadinski et al. (submitted). The field labeled “BlockSite” links th

iCoast - Did the Coast Change? Crowd-Sourced Coastal Classifications for Hurricane Sandy

On October 29, 2012, Hurricane Sandy made landfall as a post-tropical storm near Brigantine, New Jersey, with sustained winds of 70 knots (80 miles per hour) and tropical-storm-force winds extending 870 nautical miles in diameter (Blake, et. al, 2013). The effects of Sandy's winds and storm surge included erosion of the beaches and dunes as well as breaching of barrier islands in both natural and

2017 U.S. Geological Survey/BC Hydro seismic data recorded at three dam sites on Vancouver Island, British Columbia, Canada

In May 2017, we acquired high-resolution seismic profiles near three dam sites (Strathcona, Laodre and John Hart dams) located on Vancouver Island, British Columbia, Canada. Our goal was to measure seismic velocities (particularly Vs) at each dam site using body and surface waves. The data were analyzed using refraction tomography and multi-channel analysis of surface waves (MASW), especially in t
