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...
The National Environmental Satellite, Data, and Information Service (NESDIS), part of the National Oceanic and Atmospheric Administration (NOAA), has an extensive history of monitoring snow and ice coverage. Accurate monitoring of global snow and ice cover is a key component in the study of climate and global change as well as daily weather forecasting. By inspecting environmental satellite imagery, analysts from the Satellite Analysis Branch (SAB) at the Office of Satellite Data Processing and Distribution (OSDPD), Satellite Services Division (SSD), created a Northern Hemisphere snow and ice map from November 1966 until the National Ice Center (NIC) took over production in 2008. Initially, the product was produced...
Vector line dataset displaying the extent of sea ice and subsea permafrost in the northern hemisphere. This is a companion dataset to the Circum-Arctic Map of Permafrost and Ground Ice Conditions .
The Multisensor Analyzed Sea Ice Extent – Northern Hemisphere (MASIE-NH) products provide measurements of daily sea ice extent and sea ice edge boundary for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection. Products include an ASCII text file of sea ice extent values in square km over the entire Northern Hemisphere with 16 separate Arctic regions identified, time series plots of the 16 regions, and image files that visually show where the sea ice is. The MASIE-NH imagery are provided at a nominal 4 km resolution. The input data comes from the 4 km Interactive Multisensor Snow and Ice Mapping System (IMS) snow and ice product produced by the National Ice Center (NIC). NIC utilizes...

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...

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: T-3 camp in August 1969: The USGS trailer is in the left center foreground. The high spot in the right side background might be the rock pile show in earlier photos but now covering with snow. This photo is likely taken from the top of the Lamont hydrohut tower. Note: T-3 Photographs - Roll I B&W negatives – August-September 1969 This roll shows activities during August and September 1969 on T-3. The summer season had now lasted two months. The weather grew cold. Photos by Dave Scoboria.
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)
Typed information accompanying negatives: Bob Sutton was the camp manager during the summer of 1969. He was soft spoken, experienced, and very capable. In mid-summer he developed an abscessed tooth and suffered for several days before it was controlled with penicillin from the medical supplies. There were no medical personnel on T-3, so if a medical problem developed it was handled over the radio. There were days when the radio communication was poor or non-existent. 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...
Typed information accompanying photograph: Slide and print: USGS hydrohut, April 1969. Taken from the ground just outside the Lamont hydrohut. Note: T-3 Photographs - Roll B - Color slides April 1969. These photos were developed into Ektachrome slides in May of 1969. Some have deteriorated. Some were printed as color prints and these may be in better condition than the slides. A few slides were copied into Kodacolor slides. Some images are missing. Photos by Dave Scoboria.
