This dataset contains information from groundwater monitoring wells at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. The information includes field and laboratory methods, site locations, and inorganic and organic chemistry data. Samples were collected between 2009 and 2023, and analyzed for inorganic anions: F (fluoride), Cl...

These data were collected to investigate how well wind speed and direction can be measured using a miniature sonic anemometer mounted in a joust configuration on a small uncrewed aircraft system (sUAS). Test flights occurred at a bog within Interior Alaska that was instrumented with an eddy covariance flux tower. Part of the tower's instrumentation was a highly accurate sonic anemometer...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

Boreal Partners in Flight developed the Alaska Landbird Monitoring Survey (ALMS) primarily to monitor breeding populations of landbirds in the vast off-road areas of Alaska in conjunction with data collected from the roadside North American Breeding Bird Survey (BBS). ALMS is a collaborative program in which agencies and other entities conduct standardized surveys of breeding birds and...

Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the...

Depth to frozen soil measurements taken by a variety of collaborators at the Alaskan Peatland EXeriment (APEX) bog/permafrost plateau site. Data is from 2018 - 2023.

This dataset consists of three tables relating to (1) detections of adult McKay's Buntings from line transect with distance estimation surveys on St. Matthew and Hall islands in Alaska between May 30 and June 29, 2003 and June 6 and 11, 2018, (2) environmental covariates associated with detections of adult McKay's Buntings in less than or equal to 250-m long contiguous transect segments...
