Data

These data are the responses of researchers, managers, community members, and tour guides who live or work in polar bear habitats anywhere within their range to inquiries about the types, frequency, and potential impacts of recreational activities. Respondents answered a series of questions on their background and experience with polar bears and the geographic area in which they are...

In the North Pacific Ocean and Bering Sea between August 2012-2014, data were collected on sea surface temperature and salinity data, marine bird and mammal surveys, hydroacoustic backscatter data, marine environment surrounding Tufted Puffin colonies, and body condition and diets of Tufted Puffin chicks.

This data set documents the carbon and nitrogen stable isotope ratios of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009.

This data set documents the stomach contents of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009.

This dataset documents the dry mass energy density, distribution, and stomach contents of age-0 chum salmon (Oncorhynchus keta) captured in the Kuskokwim Bay estuary in May and June 2004.

This dataset provides four digital elevation models derived from airborne lidar data acquired over four separate areas along and adjacent to the Fairweather Fault along the remote Gulf of Alaska coast within Glacier Bay National Park. In 1958, the Fairweather Fault in southeast Alaska ruptured over 260 km between Yakutat Bay and Cross Sound, producing the magnitude 7.8 Lituya Bay...

These are data from cruises carried out in April, May and July 2010 from the Copper River (AK) mouth to beyond the shelf break, approximately 150 km from shore. The focus of the dataset is the iron (Fe) data, intended to help infer the processes controlling concentrations of Fe. The data include concentrations of total dissolvable Fe (TDFe), dissolved Fe (dFe), nitrate, and salinity...

This dataset consists of survey data, plots, photos, and a photo index from a cross section survey of the Eklutna River at the Glenn Highway bridge in Alaska. The cross sections were surveyed in 2016 and 2017 using a total station, then adjusted to match datums for a Municipality of Anchorage orthophoto and Alaska Department of Transportation and Public Facilities bridge as-built...

This data was produced as part of a subsurface tracer experiment performed on a boreal hillslope in July, 2015. The data is separated into three files: 'subsurfaceFlow_bromideTracer_well_wTwinCr_koch.csv' includes the location and depth of well screens, concentrations of the bromide tracer in time, saturation state of the subsurface at the wells, ground cover at the wells, and depth of...

This data release includes remotely sensed lake and lake chemistry and water temperature data collected from 2011 to 2014) from a series of lakes on the Arctic Coastal Plain of Alaska. Most of the data is from two sites within the Chipp River Basin.

This dataset includes two spreadsheets associated with a study of three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) in 185 Spectacled Eiders (Somateria fischeri) sampled in Alaska, 2008-2012. The first spreadsheet provides age, sex, location, and blood parasite (hematozoa) infection data for three different genera of blood parasites. Hematozoa DNA, from eider...

This data set includes information on collections of fecal or cloacal samples from wild birds at a location in Alaska, USA. Samples were screened for Escherichia coli (E. coli) and tested for resistance to multiple antibiotics. These data were used to identify and genetically compare antibiotic-resistant E. coli isolates in wild migratory birds inhabiting a landfill habitat in Alaska...
