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...
Gulf Watch Alaska Nearshore Component: Sea Otter Aerial Survey Data Kenai Fjords National Park, 2002-2016 Gulf Watch Alaska Nearshore Component: Sea Otter Aerial Survey Data Kenai Fjords National Park, 2002-2016
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...
Count of Sockeye Salmon (Oncorhynchus nerka), River Temperature, and River Height in the Pilgrim River, Nome, Alaska, 2003-2014 Count of Sockeye Salmon (Oncorhynchus nerka), River Temperature, and River Height in the Pilgrim River, Nome, Alaska, 2003-2014
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...
Sensor and Location Data from Ear Tag PTTs Deployed on Polar Bears in the Southern Beaufort Sea 2009 to 2011 Sensor and Location Data from Ear Tag PTTs Deployed on Polar Bears in the Southern Beaufort Sea 2009 to 2011
These are data collected from Wildlife Computers ear tag platform transmitter terminals (PTT) deployed on polar bears in the southern Beaufort Sea during the months of March, April, August, September, and October between 2009 and 2011. Purpose is to examine the performance and retention of ear tag satellite transmitters attached to polar bears.
Sea Otter Forage Observations from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound Sea Otter Forage Observations from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park and Prince William Sound
These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore component and a seasonal diet study in Kenai Fjords National Park. This dataset consists of observations made of foraging sea otters (Enhydra lutris). Observers used Questar field model spotting scopes and binoculars to identify prey. Date, local time, dive duration, success, prey type, prey size...
Black Oystercatcher Nest and Diet Data from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park, and Prince William Sound Black Oystercatcher Nest and Diet Data from Kachemak Bay, Katmai National Park and Preserve, Kenai Fjords National Park, and Prince William Sound
These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset is comprised of six comma separated values (.csv) file exported from a relational database. The data consist of: 1) transect summary, 2) nest details, 3) egg float and stage data, 4) chicks diets, 5) chick diet taxonomy, and 6) Gulf Watch Alaska contributors...
