Data

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...

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...

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...

This data set contains information regarding the sampling of avian influenza viruses from mallard ducks at locations in Anchorage and Fairbanks, Alaska 2012-2015. Data pertaining to wild birds (mallards) sampled includes band numbers, age and sex, location and timing of sampling. Laboratory specific data is also included and used to identify presence and absence of avian influenza...

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...

This data release has been SUPERSEDED. No data are provided here. Data from Gulf Watch Alaska nearshore water and air temperature sampling data releases have been appended to U.S. Geological Survey data release: https://doi.org/10.5066/F7WH2N3T. This data is part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. The data consists of date, time...

These data are is part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Kenai Fjords National Park between 2002 and 2016. Sea otters are a keystone predator, well known for structuring the nearshore marine ecosystem through their...

We are provoding a set of table and maps that provides summary of ecosystem carbon balance (pools and fluxes) as simulated by the Dynamic Organic Soil version of the Terrestrial Ecosystem Model. Simulations are provided for the historical period from 1950 to 2009 and projections from 2010 to 2099, for the four main landscape conservation cooperative regions in Alaska (i.e. the Arctic...

This data set contains information on blood chemistry and hematological parameters of captive Pacific Common Eiders (Somateria mollissima v-nigrum) for reference periods and after satellite transmitter implantation. These data were collected for health assessments, to evaluate seasonal changes in regularly measured biomarkers, to assess the physiological responses to dive conditioning...

This data release contains three tables of information on behavior and productivity of greater white-fronted geese nesting near Point Lonely, Alaska, 2013-2014: 1) transcriptions of nest photographs obtained by time-lapse photography at 1-minute intervals in 2013, 2) transcriptions of nest photographs obtained by time-lapse photography at 1-minute intervals in 2014, and 3)...

The dataset is the daily count of Sockeye Salmon (Oncorhynchus nerka) passing through a fish counting weir on the Pilgrim River from 2003 to 2014. Also, included in the data set is the daily temperature and river height measured at the weir (65.103071°, -164.824046°).The fish weir was operated during the summer (late June to mid-September) by the Norton Sound Economic Development...

These are genetic data collected from over 700 individual coho salmon (Oncorhynchus kisutch) from 17 streams and rivers within Glacier Bay Alaska and 2 rivers outside the bay. Data collected from all samples include one nuclear gene intron, Growth Hormone-1, and eight microsatellite loci.
