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.

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...

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...

Hydrologic data for the Alaska Arctic are sparse, and fewer still are long-term (> 10 year) datasets. This lack of baseline information hinders our ability to assess long-term alterations in streamflow due to changing climate. The Arctic LCC is provided stop-gap funding to continue this long time series hydrological data sets in the Kuparuk and Putuligayuk watersheds.

The USGS and Arctic National Wildlife Refuge Staff operate and maintain a streamgage at Hulahula River near Kaktovik, Alaska. Data from this station is necessary to complement glacier mass-balance studies and provide information necessary to project stream flow regimes under various scenarios of climate change. This project includes operation, acquiring real-time data, analysis of the data, and internet access. The gauge continues to operate as of 2017.

LCC funding for this project helped maintain a network of hydrology monitoring sites in a representative watershed of the Arctic Coastal Plain. The work was conducted within the context of climate change and impending oil and gas activities in the region, the latter of which is the impetus for focusing on the Fish Creek watershed. The project included two monitoring components:1) Beaded Stream & Lake Hydrology Monitoring (dominant habitat type within the watershed): in 6 stream/lake complex watersheds (Redworm, Hannahbear, Blackfish, Crea, Oil, and Bills creeks), continuous water level and temperature (in lakes, streams, and confluences), discrete discharge measurements, and continuous water quality (specific conductivity,...

Work completed by ANTHC has identified climate-related active and potential human health threats in three thematic areas: 1) Permafrost changes; 2) Habitat changes; 3) Impacts on wildlife. Rural villages in Arctic Alaska have requested, and received in-depth environmental health assessments, and adaptation strategies are in development. In response to these findings, ANTHC has developed the RAMP, and is collaborating with UA to develop relevant monitoring and surveillance tools for the thematic areas identified. This includes a training curriculum for village residents who will be observing, monitoring the RAMP technology, and collecting specimens. In addition, the UA will be funded to develop laboratory technology...
Lack of complete snow cover for the past 3 winters in southwestern Alaska has forced agencies to postpone moose surveys due to the likelihood of underestimating the population/lack of comparability to previous surveys. Poor snow conditions lower the sightability of moose, yet, for most regions of Alaska, the variation in moose sightability during suboptimal conditions has not yet been quantified. Because scientists are predicting less snowfall in this region over the long term, we initiated research to estimate sightability correction factors (SCF_c) using radiocollared animals to apply to abundance estimates obtained via the GeoSpatial Population Estimator (GSPE) method. The Project Goal is to develop a model that...

The Arctic LCC has partnered with USGS to complete a feasibility study that will review current and past efforts to monitor thermokarst at broad spatial and temporal scales, compare relevance, cost, and strengths/weaknesses of the various approaches and techniques. Researchers have outlined potential study designs for monitoring thermokarst events that emphasize processes affecting large areas, or with a disproportionately large impact on fish and wildlife habitat quality. Information available in the final report includes: 1) review existing thermokarst monitoring methods via a literature review, 2) provide a brief description and review of thermokarst landforms and processes associated with permafrost degradation...

The identification of heavy metals such as mercury, and highly persistent lipophilic anthropogenic contaminants in the circumpolar food chain of all Arctic countries has raised awareness in wildlife scientists, and human health authorities on the need to better understand the possible climate-mediated influence on atmospheric and ocean transport mechanisms on the exposure of biota, including humans, in the Arctic. Certain contaminants are known to interfere with immune response in both humans and wildlife.Researchers developed a village climate and health impact assessment tool; identified climate change vulnerabilities for the Native Village of Selawik and developed a climate adaptation strategy; developed biomonitoring...

If current trends continue, Brooks Range glaciers will disappear over the next century, affecting stream flow regimes, riparian areas, and deltas. In turn, changes in stream habitat will impact local fisheries and the subsistence users who depend on them. To better understand glacier-climate interactions, researchers from the University of Alaska’s Institute of Northern Engineering monitored glaciers in the Hulahula watershed from 2010 through 2014. Their work extended the 50-year mass balance (annual difference between accumulation and loss of material) record for McCall Glacier and initiates investigations of Esetuk Glacier. By integrating the study of the McCall Glacier with long-term research on the impacts...

BioMap Alaska is a citizen science observation and information management tool. BioMap Alaska engages residents of coastal communities to voluntarily report observations and local knowledge of marine life. This project is intended to improve and expand upon science based monitoring activities, and to further cooperation and collaboration among local people, researchers, and resource managers. We provide a field guide of “species of interest” on which we are seeking information and web-based data logging so that that observers can enter their observations and view these on an online map. Anyone who is interested can view the BioMap data.WHY DO WE NEED BIOMAP ALASKA?There are ongoing and significant ocean environment...
