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.

Code, input data, and simulated spatiotemporal distributions and energetic profiles for a model of mallard and northern pintail migration across the Northern Hemisphere Code, input data, and simulated spatiotemporal distributions and energetic profiles for a model of mallard and northern pintail migration across the Northern Hemisphere
These data and code were collected to support the development of a modeling framework that integrates local daily weather conditions and land cover with individual energetics and morphology to simulate mallard (Anas platyrhynchos) and northern pintail (Anas acuta) migration across the Northern Hemisphere.The simulated birds move across a discretized landscape of 20 by 20 mile nodes...
Estimates of habitat suitability of reed canarygrass (Phalaris arundinacea) in Upper Mississippi River floodplain forest understories (ver. 2.0, February 2024) Estimates of habitat suitability of reed canarygrass (Phalaris arundinacea) in Upper Mississippi River floodplain forest understories (ver. 2.0, February 2024)
This dataset contains predictions of habitat suitability of reed canarygrass (Phalaris arundinacea) in Upper Mississippi River floodplain forest understories from Pool 3 to Pool 13. Predictions were created using three machine learning algorithms (Bayesian additive regression trees, boosted trees, and random forest). This dataset contains rasters that provide habitat suitability...
GPS Tracking Data for the Nelchina Herd Caribou (Rangifer tarandus granti), Alaska, 1999-2002 GPS Tracking Data for the Nelchina Herd Caribou (Rangifer tarandus granti), Alaska, 1999-2002
These data were part of a tracking study of adult female caribou from the Nelchina Herd in Alaska. The dataset is comprised of two comma separated values (.csv) files. Data includes: 1) processed (i.e., erroneous locations removed) GPS locations for caribou, received once per 7 hours (October 1999 to October 2002), and 2) spatial, temporal, and biological attributes of the female caribou...
Experimental results from intact core incubations of nearshore sediments in Lake Kabetogama, MN (2021, 2022) Experimental results from intact core incubations of nearshore sediments in Lake Kabetogama, MN (2021, 2022)
Lake water level fluctuations are an important factor driving variation in many ecosystem processes. The nearshore sediments that are periodically exposed and re-inundated can develop distinct physical and chemical characteristics, especially in relationship to the organic matter content of the sediments and the particle size distribution. These sediment characteristics in turn can alter...
Efficacy of carbon dioxide for preventing quagga veliger settlement in a raw water system on the Colorado River, AZ Efficacy of carbon dioxide for preventing quagga veliger settlement in a raw water system on the Colorado River, AZ
We evaluated the efficacy of carbon dioxide (CO2) for preventing settlement of the biofouling quagga mussel (Dreissena bugensis) in raw water systems. Trials were conducted in a mobile laboratory located at the US Bureau of Reclamation, Davis Dam Hydropower Facility, and supplied with raw water from the Colorado River. Incoming water was split between five chambers where CO2 was...
Data Release for Using Environmental DNA to Effectively Detect Aquatic Arthropods: Monitoring Seasonal Changes in eDNA Concentration Data Release for Using Environmental DNA to Effectively Detect Aquatic Arthropods: Monitoring Seasonal Changes in eDNA Concentration
Detection of environmental DNA (eDNA) has become a commonly used surveillance method for threatened or invasive vertebrates in both aquatic and terrestrial environments. However, use of eDNA methodologies for the detection of aquatic invertebrates (e.g., crayfish and insects) has been limited. Environmental DNA protocols can be especially useful for endangered invertebrates such as the...
