Data and Tools

Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Water chemistry of cropped wetlands and associated subsurface drainage system discharge in the Prairie Pothole Region of North Dakota, 2013–2015

A field study was conducted in the Prairie Pothole Region of North Dakota to examine potential effects of localized subsurface drainage systems on wetland hydrology. As part of discrete studies utilizing the study sites (wetland catchments) from this study, samples of wetland surface water and subsurface drainage system effluent were collected from 2013–2016 and analyzed for standard...

Surveying butterfly populations of prairie restorations in South Louisiana

In this study our objective was to establish baseline abundance numbers of butterflies and to evaluate a monitoring system that can be used by persons with relatively little experience to assess changes in butterfly abundance. Because butterflies that depend on grasslands use flowering plants as nectar sources and a variety of plant species as larval host plants, nectar and pollen resources...

Spectacled Eider (Somateria fischeri) Microsatellite and Mitochondrial DNA Data, 2014-2018, Alaska and Russia.

This data set describes nuclear microsatellite genotypes derived from ten autosomal loci (Aph8, Aph16, Cmo7, Cmo9, Hhi5, Sfi10, Smo4, Smo6, Smo8, Smo12) and nucleotide sequence data derived from one mitochondrial DNA locus (control region). A total of 262 Spectacled Eiders were examined for this study. Samples were collected at Indigirka and Chaun River Deltas, Russia, and Yukon-Kuskokwim...

Glacier-Wide Mass Balance and Compiled Data Inputs: Juneau Icefield Glaciers

Since the 1940s, the Juneau Icefield Research Program (JIRP) has been measuring surface mass balance on the Juneau Icefield. This is the longest ongoing program of its kind in North America. The program nominally occurs between late June and late August, traversing between Juneau, Alaska and Atlin, British Columbia. JIRP has examined the surface mass balance of the Juneau Icefield since 1946,...

Post-wildfire debris flow and rainfall data, Whitewater-Baldy complex fire, southwestern New Mexico

During the spring and early summer of 2012, approximately 1,200 square kilometers of Gila National Forest in southwestern New Mexico, including the upper portions of the Whitewater Creek watershed, were burned by the Whitewater-Baldy Complex Fire. The following September 12-17, 2013, a near-record, one-week long storm event produced widespread, historic rainfall amounts throughout the...

Dissolved greenhouse gas concentrations and fluxes from Wetlands P7 and P8 of the Cottonwood Lake Study area, Stutsman County, North Dakota, 2015

A study was conducted to assess the relationships among carbon mineralization, sulfate reduction and greenhouse gas emissions in prairie pothole wetlands. These data are for dissolved methane and carbon dioxide concentrations and fluxes. Dissolved gas concentrations in the water column and fluxes to the atmosphere were estimated from April through November, 2015 for wetlands P7 and P8 of the...

Brodifacoum toxicity in American kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure - Results of trial 3

A heterologous thrombin clotting time assay (TCT) was used to measure the time for conversion of fibrinogen to fibrin using commercially available reagents. Human reference material included in the kit was diluted with imidazole buffered saline (IBS; 0.0125M imidazole-0.109 M sodium chloride, pH7.4) to generate a standard curve. Each kestrel plasma sample was thawed at 37ºC and...

Physical, Chemical, and Invertebrate Data from Chipp North Pond Manipulations, North Slope, Alaska, 2013

These data are in three tables relating to a series of ponds, visited weekly over the summer of 2013, in the Chipp River Basin on the Arctic Coastal Plain of northern Alaska. The tables provide: 1) location and description of each of the ponds, 2) physical information on pond characteristics (area, volume, and temperature), water chemistry (electrical conductivity, dissolved oxygen, pH,...

Pseudogymnoascus destructans survival at elevated temperatures – Artificial media count data

The survival of Pseudogymnoascus destructans (Pd) was evaluated at temperatures outside of its thermal range of growth on three different artificial growth media; Sabouraud dextrose agar (SD), brain-heart infusion agar (BHI), and brain-heart infusion agar supplemented with 10% sheep red blood cells (BHI+B). Pd was harvested from starting cultures grown of MEA agar at 7˚C for 60 days....
