Data Releases
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.

Winter tick counts and covariates in Massachusetts and New Hampshire from fall 2022 Winter tick counts and covariates in Massachusetts and New Hampshire from fall 2022
The dataset accompanies manuscript: "Monitoring off-host winter tick abundance on traditional moose hunting lands" . It is a single table that includes counts of winter tick (Dermacentor albipictus) obtained by a modified flagging technique developed by the Penobscot Nation. The table includes both detection and site covariates used for the data analyses presented in the paper. Data were...
Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2022 Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2022
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), organic carbon, and general water quality characteristics in Pinyon Plain Mine containment pond water, invertebrate, vegetation and sediment samples, collected in calendar year 2022.
Method development for determination of trace amounts of silicon in hydrofluoric acid digests of biological samples and lung biopsy tissues by ICP-MS Method development for determination of trace amounts of silicon in hydrofluoric acid digests of biological samples and lung biopsy tissues by ICP-MS
A method was described for determination of trace levels of silicon by inductively coupled plasma mass spectrometry (ICP-MS) from hydrofluoric (HF) digests of biological samples. The volatility of silicon in HF digests was examined with synthetic solutions as well as soil and mine waste samples. A digestion scheme was optimized to achieve complete dissolution, avoid loss of volatile...
Histopathology of American Kestrels (Falco sparverius) Exposed to Two Brodifacoum Isomer Formulations with Differing Elimination Half-Lives Histopathology of American Kestrels (Falco sparverius) Exposed to Two Brodifacoum Isomer Formulations with Differing Elimination Half-Lives
This dataset documents histopathological changes in liver, kidney, skeletal muscle and intestine of captive American kestrels (Falco sparverius) exposed to brodifacoum formulations with differing elimination half-lives in target rodents. The toxicity of two brodifacoum formulations with stereoisomers having markedly different elimination half-lives in rats (Formulation A containing the 2...
Roundtail Chub and Flannelmouth Sucker movement data within the Blacks Fork subbasin, Wyoming 2019-2021 Roundtail Chub and Flannelmouth Sucker movement data within the Blacks Fork subbasin, Wyoming 2019-2021
The dataset includes Roundtail Chub and Flannelmouth Sucker detections at passive integrated transponder (PIT) tag antenna systems. We installed nine instream Biomark PIT-tag antenna systems (five 24-meter and four 9-meter antennas) in a pass-over orientation throughout the Blacks Fork subbasin. In addition to the fixed antennas, we used a Biomark inflatable antenna and two Biomark...
Post-wildfire rain gage data for Fourmile Canyon, Colorado and Rendija Canyon, New Mexico Post-wildfire rain gage data for Fourmile Canyon, Colorado and Rendija Canyon, New Mexico
Rain-gages are critical instrumentation for documenting the rainfall forcing of post-wildfire hydrologic, erosional, and water-quality response. This USGS Data Release presents tipping-bucket rain gage data following two wildfires: the 2000 Cerro Grande Fire near Los Alamos, New Mexico and the 2010 Fourmile Canyon Fire near Boulder, Colorado. The data presented in this USGS Data Release...
