Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.
The Anaktuvuk River Fire was the largest, highest-severity wildfire recorded on Alaska’s North Slope since records began in 1956. The 2007 Anaktuvuk River Fire was an order of magnitude larger than the average fire size in the historic record for northern Alaska and indices of severity were substantially higher than for other recorded tundra burns. An interdisciplinary team assessed fire effects including burn severity, potential plant community shifts, and effects on permafrost and active layers. Observers monumented, photographed, and measured 24 burned and 17 unburned reference transects, starting the year after the fire, and spanning the range of vegetation types and burn severities.
The purpose of this project is to provide better information to industry and regulatory agencies regarding the likely locations of polar bear dens. This project integrates snow physics, high-resolution digital elevation data, and bear biology to produce more refined and accurate maps predicting suitable polar bear den habitat than are currently available. The work consists of data gathering, consultation between snow and bear scientists, modeling, and sensitivity studies to understand the various factors influencing den location and evolution along the Beaufort Coast.The proposed work is intended to refine current methods of identifying polar bear denning sites by incorporating higher-resolution topographic data...

The Beaufort Sea coast in arctic Alaska and neighboring northern Canada has recently experienced extreme and accelerated climate change, including a dramatic reduction in summer sea ice (Gildor and Tziperman 2003, Holland et al. 2006). This absence of ice allows increased wind and wave energy to directly affect the coast, resulting in island and mainland flooding, coastal erosion, and further movement of barrier islands and beaches. The period each year in which the arctic is free of summer ice is increasing and is predicted to increase non-linearly in the future. This suggests a “tipping point” has been reached, producing internal feedback mechanisms that will further accelerate coastal change (Comiso et al., 2008).These...
There are many challenges in detecting precipitation trends in Alaska. The most substantial are the small number of observations, inhomogeneities, differences among gridded data sets, and differentiating between long-term trends and decadal variability. Analyzing both station and regional products will increase our understanding of where local trends in precipitation may differ significantly from regional trends, providing key information for developing better downscaled climate projections. These in turn, will provide insight into fine scale heterogeneity in climate change that may be important in determining the stability of key habitat features, such as wetlands and insect avoidance areas. As a by-product of...
LCC funding allowed completion of this BLM initiative to develop a North Slope-wide cover type map and create a crosswalk that integrates all component cover type maps that comprise the larger overall North Slope cover type map.This map is the outcome of a multi-year project to produce a moderate resolution landcover base map for the North Slope of Alaska to serve as a primary base layer for long-term science and planning activities on the North Slope. New Landsat Thematic Mapper (TM) 30 meter resolution landcover maps were produced for the far western arctic, and for the area between the National Petroleum Reserve - Alaska (NPRA) and Arctic National Wildlife Refuge. In the NPRA, an existing land cover map from...
Arey Lagoon and Island, situated on the Beaufort Sea coast just west of Barter Island and within the Arctic National Wildlife Refuge (ANWR), was selected as a focus site for an in-depth study of coastal processes on a regional to local scale. Arey Lagoon and adjacent areas encompass a barrier island chain, a glacially fed river and delta (Hulahula and Ogpilak Rivers) from the Brooks Range watershed, low-lying tundra with coastal wet sedge, and thermokarst lakes that all may be vulnerable to the effects of changing storm patterns in response to climate change.Analysis of historical maps and imagery showed that Arey Lagoon mainland coast, partially protected by Arey Island from the direct attack of ocean waves, was...
The Imiq Hydroclimate Database houses hydrologic, climatologic, and soils data collected in Alaska and Western Canada from the early 1900s to the present. This database unifies and preserves numerous data collections that have, until now, been stored in field notebooks, on desktop computers, as well as in disparate databases. Synthesizing and analyzing the large-scale hydroclimate characteristics of this important climatic region have been made easier with this searchable database. The data, originally collected in a Microsoft SQL Server 2008 relational database, has been migrated to an open source PostgreSQL and PostGIS environment. The Imiq Data Portal provides public access to portions of the Imiq Hydroclimate...

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

Information on the nature and distribution of permafrost is critical to assessing the response of Arctic ecosystems to climate change, because thawing permafrost under a warming climate will cause thaw settlement and affect micro-topography, surface water redistribution and groundwater movement, soil carbon balance, trace gas emissions, vegetation changes, and habitat use. While a small-scale regional permafrost map is available, as well as information from numerous site-specific large-scale mapping projects, landscape-level mapping of permafrost characteristics is needed for regional modeling and climate impact assessments. The project addresses this need by: (1) compiling existing soil/permafrost data from available...
The ShoreZone in the Classroom Curriculum Implementation project built upon the ShoreZone in the Classroom Pilot Networking Trip. Educational Consultant Marie Acemah liaised over email and in-person at the North Slope School District (NSBSD) Curriculum Camp in Barrow to develop Curricular Units that make ShoreZone available as an educational tool in NSBSD classrooms. This project resulted in two Units, specifically: 1) Coastal Ecosystems Unit; and 2) Documentary Filmmaking Summer Intensive Proposal. The ShoreZone tool is now available and accessible throughout the NSBSD district. The District and the Ilusagvik College are interested in partnering with ShoreZone to lead for-credit summer documentary film camps in...
The Beaufort Sea coast in Arctic Alaska and neighboring northern Canada has recently experienced extreme and accelerated climate change, including a dramatic reduction in summer sea ice. Human systems will likely be impacted through changes to oil industry and community infrastructure currently in place along parts of the coast, to habitat availability for harvested species such as caribou, waterbirds, and anadromous fish, to culturally important landscape elements, and to both recreational and subsistence coastal access. We used literature review and structured interviews to 1) identify current, broad interests for ongoing coastal research in the arctic, 2) identify the best mechanisms and format for communicating...
The Nature Conservancy (TNC) drew upon its existing Canadian network to coordinate with potential Canadian partners on behalf of the Arctic LCC. TNC addressed the Arctic LCC’s need to identify specific overlapping goals, objectives and geographic interest between the Arctic LCC and those potential partners. TNC provided information about the Arctic LCC to potential Canadian partners; initiated contact and helped build relationships with those potential partners; they summarized current and planned climate-related work and other areas of overlapping interest with the Arctic LCC, and identified the top six to eight most appropriate potential Canadian partners with which the Arctic LCC should engage.
More information is needed about species composition, abundance, or distribution of the microfauna and meiofauna living within the interstitial spaces of the littoral zones along the Beaufort Sea coast. Shorebirds depend on meiofauna for food for pre-migratory fattening and these organisms make important contributions to bioremediation of oil spills.The information obtained from this jointly-funded research can contribute to development of mitigation measures and strategies to reduce potential impacts from post-lease exploration and development. This information need extends to the lower trophic levels forming the base of these complex food webs and the biochemistry that influences these relationships. Their contributions...
To elucidate these potential “bottom up” effects of climate changes to Arctic ungulates and evaluate the trophic mismatch hypothesis, the Arctic Landscape Conservation Cooperative (ALCC), the Bureau of Land Management (BLM), the U.S. Geological Survey (USGS), Teck, Inc., and the National Park Service provided funding in 2012-14 to incorporate the calving and summer range of the Western Arctic caribou herd (WAH) into an ongoing inter-agency research and monitoring effort to examine the influences of climate change on the nutrient dynamics of caribou forages. This work is leveraging existing projects on the North Slope of Alaska that are primarily funded through the USGS Changing Arctic Ecosystems Initiative. Field...
Our overarching questions are: (1) How much of the river water and water-borne constituents (i.e. sediment, nutrients, organic matter) from the Jago, Okpilak and Hulahula rivers are coming from glacier melt? (2) How do inputs from these rivers affect the downstream ecosystems? (3) How will loss of glaciers affect these ecosystems? The study will help elucidate how inputs from glacier-dominated arctic rivers differ from unglaciated rivers, through a combination of ground work, boat work, and remote sensing. In Phase One of this study, we intend to explore the relationship between glaciers and coastal ecosystems. Our goal in this phase-one study is not to answer these questions conclusively but rather improve our...
The Bureau of Ocean Energy Management (BOEM) is supporting a field effort in support of a ShoreZone mapping project along the Chukchi and Beaufort coasts. Funds from the LCC will allow for the inclusion of three additional ShoreStations. Researchers will conduct ground surveys to get detailed physical and biological measurements throughout the various and often unique Chukchi and Beaufort coastal habitats. Sediment samples will be archived from each shore station for hydrocarbon analyses in the event of a local or regional oil spill. The Arctic ShoreZone Shore Stations will be added to the statewide database and made available online to the public NOAA website.
