This data set describes nuclear microsatellite genotypes derived from twenty-one autosomal loci (Fal02, Fal04, Fal07, Fal08, Fal10, Fal12, Fal14-1, Fal16, Fal 17, Fal19, Gch03, Gch06, Gch07, Gch12, Gch13, Gch14, Gch17, Gch19, Pho110, KiRa9 - 1, and KiRa10) and nucleotide sequence data derived from two mitochondrial DNA loci (control region and NADH dehydrogenase 2). Samples were...

Greater White-Fronted Goose Genetic Data, Circumpolar, 1988-2009 Greater White-Fronted Goose Genetic Data, Circumpolar, 1988-2009

This data set describes nuclear microsatellite genotypes derived from eight autosomal loci (BCA6, BCA9, BCA11, BCA5, CRG, OXY13, TSP1.20.09 and TSP1.20.46) and a 366 base pair portion of the mitochondrial control region. A total of 665 Greater White-fronted Geese were examined by genotyping and 518 by sequencing with samples coming from its circumpolar range representing multiple flyways

Exit and Paradise Glacier Foreland, Alaska River and Glacier Maps, Channel Surveys, Digital Elevation Model, and Orthophoto, 1800s-2013 Exit and Paradise Glacier Foreland, Alaska River and Glacier Maps, Channel Surveys, Digital Elevation Model, and Orthophoto, 1800s-2013

This data release provides eleven datasets related to the fluvial area immediately downstream of the Exit and Paradise Glacier on Alaska's Kenai Peninsula. Datasets include maps of historical Exit and Paradise creek and glacier positions, 2013 channel survey and particle size data, and a 2012 digital elevation model (DEM) and orthophoto of the Exit and Paradise glacier forelands, in...

Data from a Circumpolar Survey on Recreational Activities in Polar Bear Habitat, 2017-2018 Data from a Circumpolar Survey on Recreational Activities in Polar Bear Habitat, 2017-2018

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...

Marine ecology near Tufted Puffin colonies across the Aleutian Archipelago and Alaska Peninsula, 2012-2014 Marine ecology near Tufted Puffin colonies across the Aleutian Archipelago and Alaska Peninsula, 2012-2014

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.

Arctic Cisco Stable Isotope Data, Prudhoe Bay, August 2009 Arctic Cisco Stable Isotope Data, Prudhoe Bay, August 2009

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.

Arctic Cisco Stomach Content Data, Prudhoe Bay, August 2009 Arctic Cisco Stomach Content Data, Prudhoe Bay, August 2009

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

Kuskokwim Bay Chum Salmon (Oncorhynchus keta) Energy Density, Distribution, and Stomach Data, 2004 Kuskokwim Bay Chum Salmon (Oncorhynchus keta) Energy Density, Distribution, and Stomach Data, 2004

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.

Digital Elevation Models of Glacier Bay National Park, Between Lituya Bay and Icy Point, Alaska, Derived from Airborne Lidar Data Acquired in September 2015 Digital Elevation Models of Glacier Bay National Park, Between Lituya Bay and Icy Point, Alaska, Derived from Airborne Lidar Data Acquired in September 2015

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...

Gulf of Alaska Shelf and Slope Iron and Nitrate Data, Copper River Region, 2010 Gulf of Alaska Shelf and Slope Iron and Nitrate Data, Copper River Region, 2010

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...
