For more than 25 years, the U.S. Geological Survey Gas Hydrates Project has compiled and maintained an internal database of locations where the existence of gas hydrate has been confirmed or inferred in research studies. The existence of gas hydrate was considered confirmed when gas hydrate was recovered by researchers or videotaped from a vehicle (such as a submersible or remotely operated vehicle) near the sea floor. The existence of gas hydrate was considered inferred when seismic data, borehole logs, or certain geochemical characteristics match anomalies known to characterize gas hydrate. This data release provides a text description of the region, geographic coordinates, and the citation for the published reference...

The T-3 (Fletcher's) Ice Island in the Arctic Ocean was the site of a scientific research station re-established by the Naval Arctic Research Laboratory starting in 1962. Starting in 1963, the USGS acquired marine heat flow data and coincident sediment cores at sites in Canada Basin, Nautilus Basin, Mendeleev Ridge, and Alpha Ridge as the ice island drifted in the Amerasian Basin. At least 584 heat flow penetrations were attempted, and data were reported at 356 of these. This dataset is the enhanced version of the original data table from Lachenbruch and others (2019; see cross-reference), incorporating additional information such as the probable dates of measurement, physiographic province and surficial geology...

Berry-producing plants, a key resource in Alaska Native communities, provide primary subsistence and have been integral to maintaining cultural cohesion, sense of place, and physical ties to the surrounding landscape. Despite the importance of berry-producing plants, relatively little is known about their vulnerability to changes in climate and environmental conditions. The dynamics of insect populations are strongly related to climate; however, very little is known about the insect pollinators of berry plants in Arctic and sub-Arctic ecosystems. This interaction between plants and pollinators is critical to plant communities and for providing fruit resources to Indigenous communities. Numerous plant species...

To meet the climate change planning and adaptation needs of Alaska managers and decision makers, I developed a set of statewide summaries of available climate change projections that can be further subset using GIS techniques for requests by management unit, watershed, or other location. This facilitates the development of tailored climate futures for decision makers’ regional or subregional management context. This file describes the source data and summaries for purposes of technical /scientific documentation. The methods and presentation for these datasets were adapted from products in previous USGS-approved IP products for the AKCASC Building Resilience Today project (e.g, Community of Kotlik et al. 2019)....

Communities, resource managers, and decision makers in Arctic Alaska are in need of scientific information to base important decisions related to anticipating and adapting to changes in temperature and precipitation. Since its inception in 2011, the Alaska Climate Science Center (AK CSC) and its partners have produced a variety of scientific products and datasets aimed at supporting this need and increasing climate change resilience in the Arctic. However, much of the information related to these activities is dispersed across many technical publications, and is often not readily accessible to those outside the research community. In an effort to make this science more available and accessible, the AK CSC is working...

This dataset includes a polygon vector shapefile illustrating the location of rapid and intensive survey plots surveyed on the Yukon Delta as part of the Program for Regional and International Shorebird Monitoring (PRISM). This dataset provides the geographical location of survey plots that can be linked to the data collected in the field via the PlotID field.A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).Much of these data have been published in Lyons, J.E., S.C.

This file provides information on shorebirds observed during 10-minutes point counts including date and time, location, weather information, and shorebird observations.These data do not represent all locations where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species, habitat, time-of-year, weather conditions, survey effort, and individual surveyor. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended...

The primary objective of this project was to monitor the growth of shorebird chicks by recapturing them from hatch to fledgling in relation to food abundance and weather conditions. In 2014 and 2015, we attempted to estimate the impacts of trophic mismatch by experimentally creating late hatched broods by refrigerating eggs to delay hatch. Transmitters were then attached to adults and chicks to follow and recapture chick in order to estimate growth rates and survival (see annual protocol documents for further information).Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these...

Typed information accompanying negative: The C-130 plane appeared out of the clouds, dropped its load and disappeared again, all within a matter of thirty seconds. Note: T-3 Photographs - Roll F B&W negatives - June paradrop, 1969. There were three paradrops during the summer of 1969 performed by Navy C-130 planes from Elmendorf Air Force Base in Fairbanks, Alaska. These are described in this website, http://www.firebirds.org/menu2/t3/t3_p02.htm On the receiving end of the paradrops on T-3, these days were the high points of the summer season. This roll documents the first paradrop, which occurred in late June on a cloudy day. The loads were delivered on target to the camp runway without mishap. The second...

Typed information accompanying slide: Returning to camp. Bob Sutton, camp leader, had loaned us the camp weasel to cross the island to retrieve the gear. The equipment included gear, heater, hose and other items. Similar to D-7. Link to this photograph is listed below in Web Links. Note: T-3 Color slides - Roll D - Color slides September 1969. These photos were developed in late 1969 after I returned from T-3 and made into Kodacolor slides. Photos by Dave Scoboria.
