Data

This dataset provides computed remotely-sensed streamflows (RSQ) at river reaches of selected rivers in Alaska. We used the relation between water-surface elevation data derived from satellite altimetry and dynamic surface water extent data derived from LANDSAT and Sentinel imagery data with the Modified Optimized Manning Method Algorithm (MOMMA) to compute remotely sensed streamflows...

This dataset contains isotope results of stable isotope (δ13C and δ15N) and radicoarbon (F14C) analyses of muscle tissue from fish collected in the nearshore Beaufort Sea, Alaska in summers 2017-2019.

This dataset is comprised of 11 geo-referenced aerial images of two study areas (Teshekpuk Lake Special Area and the Chipp River) in the National Petroleum Reserve - Alaska (NPRA) on Alaska's Arctic Coastal Plain. The images are from aerial photo survey flown by NASA in 1974, 1977, 1979 and obtained from the Earth Resources Observation and Science (EROS) Center using the USGS...

This dataset is comprised of one geo-referenced aerial image from the National Petroleum Reserve - Alaska (NPRA) on Alaska's Arctic Coastal Plain taken on 21 June 1955 by the U.S. Air Force and obtained from the Earth Resources Observation and Science (EROS) Center using the USGS EarthExplorer website in 2013. The image represents a historical snapshot of the landscape from that time.

This dataset is comprised of 35 geo-referenced aerial images of four study areas (Teshekpuk Lake Special Area, Chipp River, Colville River Delta, and Dalton Highway Corridor) on Alaska's Arctic Coastal Plain. The images are from aerial photo surveys flown in 1948-1949 and obtained from the Earth Resources Observation and Science (EROS) Center using the USGS EarthExplorer website. The...

This data package includes four (4) child items with data from the Gulf Watch Alaska (GWA) long-term monitoring program (nearshore monitoring component) rocky intertidal study. Child Item One: "Rocky Intertidal Sea Star Size, Count, and Disease Data from Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park". The data include: (1) size and disease state...

This dataset is derived from images from a variety of Earth observing satellite imagery sources collected at known walrus coastal haulouts in Alaska and Chukotka, Russia. Earth observing imagery sources used in this data release include (but are not limited to) optical imagery collections by: (1) the European Space Agency's Sentinel-2 mission, (2) the Plant Labs Planet Scope...

We have archived the derived data files and R/JAGS code for our analysis as a U.S. Geological Survey data release (link ). The code is divided into three R scripts: 1) pbdens_landdens_JWM.r contains R code for fitting hierarchical Bayesian models of polar bear maternal den abundance and distribution for the Southern Beaufort Sea (SBS) subpopulation, 1982-2015. This script requires the...

This data package presents raw legacy data collected during 1980 on the Yakutat Forelands of southeast Alaska. The data were collected to identify and understand the occurrence and distribution of birds and mammals in the ocean and wetlands near Yakutat. Migration "sea watches", aerial surveys, and ground plot surveys were conducted in the foreland area of Yakutat in spring (April - May)...

These are surgery data sheets filled out during operations on many bird species by the USGS Alaska Science Center, 1993-2012. The majority of surgeries were to implant intracoelomic tracking transmitters, but a subset were to collect liver biopsy samples. The data sheets provide information about individual surgeries, including: data about each bird, the timing of steps during each...

This dataset contains the growth index from annual growth bands in the shells of two bivalve clam species (Astarte borealis and Liocyma fluctuosa) captured in the Chukchi Sea, Alaska. The growth index is based on a measurement of the annual growth increment width that has been detrended for age-related differences in growth.

This dataset consists of one table containing whole-rock geochemistry data for 753 igneous and metamorphic rocks from the Yukon-Tanana upland of eastern interior Alaska, collected between 2013 and 2019. All materials were analyzed by ALS Global, between 2014 and 2020, by a range of different techniques, so multiple unique entries for a given element relate to different analytical methods...
