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...
