This collection of GIS layers was prepared for the report Alaska Arctic Marine Fish Ecology Catalog (U.S. Geological Survey Scientific Investigations Report 2016–5038). The layers display geographic distribution and sampling locations for Arctic marine fish species in the region of United States sectors of the Chukchi and Beaufort Seas. Certain diadromous species (for example, Pacific salmon, char, and whitefishes) are treated as marine fishes (McDowall, 1987) because much of their life cycle is in marine and brackish environments. This synthesis of information is meant to provide current information and understanding of this fauna and its relative vulnerability to changing Arctic conditions. There are 104 species...

Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/gcb.12875/abstract): Permafrost thaw can alter the soil environment through changes in soil moisture, frequently resulting in soil saturation, a shift to anaerobic decomposition, and changes in the plant community. These changes, along with thawing of previously frozen organic material, can alter the form and magnitude of greenhouse gas production from permafrost ecosystems. We synthesized existing methane (CH 4) and carbon dioxide (CO 2) production measurements from anaerobic incubations of boreal and tundra soils from the geographic permafrost region to evaluate large-scale controls of anaerobic CO 2 and CH 4 production and compare the relative importance...

This dataset consists of short-term (~32 years) shoreline change rates for the north coast of Alaska between the U.S. Canadian Border and the Hulahula River. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1978 and 2010. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.

This dataset consists of short-term (~31 years) shoreline change rates for the north coast of Alaska between the Point Barrow and Icy Cape. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1979 and 2010. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.

Alaska’s high-latitude, arctic landscape places it at the front lines of environmental change. Factors such as rising temperatures, altered precipitation patterns, and associated shifts in growing degree days, summer season length, extreme heat, and the timing of spring thaw and autumn frost are rapidly changing Alaska’s ecosystems and associated human systems. The ability of Alaska’s land managers and communities to predict these changes will profoundly affect their ability to adapt. The State of Alaska recognizes the scope and magnitude of these changes and has made it a priority to ensure anticipated change is incorporated into local and regional planning. This project will involve collaboration with agency...

The RTK survey, using a Trimble unit, was conducted in August 2021 in the coastal plains region (1002 area) of the Arctic National Wildlife Refuge, as part of a landscape vulnerability assessment. A total of six transects are included in the data, including five research sites and one transect collected at the camp site. Mean horizontal precision was 0.006m, mean vertical precision was 0.011m.

Typed information accompanying negative: Waiting for the plane. The weather was cool but not cold, juding from the clothing. Similar to F-5 and F-6 (see links in Related Items below) 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...

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 paradrop was similar, one month later. The day of the third paradrop was windy and the sky was overcast. We did not...
Typed information accompanying negative: The landscape and hydrohut in July. By mid July the weather was starting to grow colder. The snow had melted and the lakes were drying up. Note: T-3 Photographs - Roll G B&W negatives – July 4,1969 This roll of photographs was mostly taken on July 4, 1969. There was a camp get together and celebration that day. There was no alcohol on T-3 at that point. Bob Sutton chose an abandoned hut to burn and that event was the high point of the day. (Photos on Roll G taken by Dave Scoboria)
