Allometrics of Baltic Tellin (Macoma balthica) Bivalves from Cook Inlet, AK, and Baie de Somme, France, 2010-2011 Allometrics of Baltic Tellin (Macoma balthica) Bivalves from Cook Inlet, AK, and Baie de Somme, France, 2010-2011
This dataset contains two tables of sampling information and size and mass measurements of the Baltic Tellin (Macoma balthica) from sites in Cook Inlet, Alaska, USA, and the Baie de Somme estuary, France.
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.
Marine Bird and Mammal Survey Data from Kachemak Bay, Katmai National Park and Preserve, and Kenai Fjords National Park Marine Bird and Mammal Survey Data from Kachemak Bay, Katmai National Park and Preserve, and Kenai Fjords National Park
These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. The dataset is a series of comma separated files exported from a survey software program (DLog, Ford Consulting, Portland, OR). The data consists of date, time, latitude, longitude, species abbreviation, count, and behavior. Each year the observers attempt to sample the same...
Denning Behavior Classifications Using Temperature Sensor Data on Collars Deployed on Polar Bears in the Southern Beaufort Sea, 1986-2013 Denning Behavior Classifications Using Temperature Sensor Data on Collars Deployed on Polar Bears in the Southern Beaufort Sea, 1986-2013
These data include two tables. The first is average daily temperatures received via satellite transmitting collars deployed on polar bears in the southern Beaufort Sea 1986-2013. The second is denning classifications for adult female polar bears in the southern Beaufort Sea using the temperature data. Denning was classified using a control chart-based algorithm applied to the temperature...
Walrus Haulout and In-water Activity Levels Relative to Sea Ice Availability in the Chukchi Sea, 2008-2014 Walrus Haulout and In-water Activity Levels Relative to Sea Ice Availability in the Chukchi Sea, 2008-2014
An animal's energetic costs are dependent on the amount of time it allocates to various behavioral activities. For Arctic pinnipeds, the time allocated to active and resting behaviors could change with future reductions in sea ice cover and longer periods of open water. The Pacific walrus (Odobenus rosmarus divergens) is a large Arctic pinniped that rests on sea ice or land between...
Biogeochemical Subsidies from Glacier Runoff into Alaska Coastal Marine Food Webs, Gulf of Alaska, 2012-2013 Biogeochemical Subsidies from Glacier Runoff into Alaska Coastal Marine Food Webs, Gulf of Alaska, 2012-2013
To demonstrate connectivity between terrestrial and marine ecosystems, we used stable (δ13C, δ15N, δ2H) and radiogenic (∆14C) isotopes to estimate the relative contribution of glacier runoff and terrestrial-derived organic matter (OM) to marine food webs. This dataset contains information on isotopic signatures from dissolved organic matter (DOM), dissolved inorganic matter (DIC) and...
