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.

Inventory of Artisanal and Small-Scale Mining (ASM) in Kabul: Points (2018)

Afghanistan is endowed with a broad range of mineral resources. Currently, the majority of mining throughout the country is comprised of informal and undocumented artisanal and small-scale mining (ASM) operations. The exact scope of excavation operations depends largely on the mineral commodity produced. In the case of gemstones, such as emeralds and rubies, small teams of miners use manual...

Least Bell's Vireo Habitat Suitability Model for California (2019)

This habitat model was developed to identify suitable habitat for the federally-endangered least Bell’s vireo (Vireo bellii pusillus) across its current and historic range in California. The vireo disappeared from most of its range by the 1980s, remaining only in small populations in southern California. Habitat protection and management since the mid-1980s has led to an increase in...

Adult emergence counts, Experiments 1 through 4

In a series of 4 experiments conducted over 4 years, natural lotic macroinvertebrate communities were colonized by placing baskets of large gravel in a riffle in the upper Cache La Poudre River, Colorado and leaving the baskets in place for 30-40 days. The communities were then exposed in experimental streams to different combinations of five metals (cadmium (Cd), cobalt (Co), copper (Cu),...

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

Range finding trial in which kestrels were fed diets containing varying quantities of brodifacoum and signs of intoxication were monitored.

Brodifacoum toxicity in American kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure - Results of trial 5

Citrated plasma samples were sent to the University of Miami Avian and Wildlife Laboratory for clinical determination of total protein, plasma electrophoresis (pre-albumin, albumin, alpha 1 globulins, alpha 2 globulins, beta globulins, gamma globulins) and aspartate aminotransferase and creatine phosphokinase activities.

Metal-mixtures experimental stream study, part 4 (2016): Co, Cu, and Ni exposures: aquatic, biofilm, tissue and sediment chemistry; larval aquatic insect counts, and algal biomass

This dataset is from the fourth of four experiments which test the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams. Here we report original data from testing the toxicity of cobalt (Co), copper (Cu), and nickel (Ni), singly and in mixtures, to natural benthic communities including aquatic insect...

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...
