These raster datasets represent historical stand age. The last four digits of the file name specifies the year represented by the raster. For example a file named Age_years_historical_1990.tif represents the year 1990. Cell values represent the age of vegetation in years since last fire, with zero (0) indicating burned area in that year. Files from years 1860-2006 use a variety of historical datasets for Boreal ALFRESCO model spin up and calibration to most closely match historical wildfire dynamics.

This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. The file name specifies the decade the raster represents. For example, a file named MAGT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated mean annual ground temperature (degree C) at the base of the active layer (for areas with permafrost) or at the base of the soil column that is seasonally frozen (for areas without permafrost). If the value of the cell is negative,the area has permafrost and the...

The Snowy Owl, a conspicuous and majestic bird of the circumpolar arctic, is an efficient hunterof small mammals in tundra environs. In years of high lemming numbers they will focus on thisabundant food source but will readily switch to a wide variety of other prey when lemmings arescarce (Parmelee 1992). Their breeding range in Alaska is generally restricted to the ArcticCoastal Plain, typically nesting in more upland tundra habitats, although they often, though notexclusively, forage in wetter tundra (Parmelee 1992). Snowy Owls are unpredictable migrantsand will sometimes “invade” portions of southern Canada and the northern contiguous US, inwinters when lemmings are scarce in the Arctic. The current global population...

The Common Eider, a large sea duck, is more closely tied to marine environments than are manyother sea ducks. On the Arctic Coastal Plain of Alaska this species nests primarily on barrierislands and peninsulas of the Arctic Coastal Plain (a small proportion of the total area) while inother parts of its range they select quite varied nesting sites (Goudie et al. 2000). Common eidersdepend on a marine prey base, eating invertebrates (primarily mollusks and crustaceans) bydiving to the sea floor. Alaskan breeders spend their winters nearby in the Bering Sea, Gulf ofAlaska, and off Russia’s Chukotka Peninsula (SDJV 2004). Current Arctic Coastal Plainpopulation is estimated at approximately 2,000 (Dau and Bollinger 2009).

Baseline (1961-1990) average summer total precipitation and projected change in precipitation for the northern portion of Alaska. For the purposes of these maps, ‘summer’ is defined as June - August. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1.01 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

Baseline (1961-1990) average winter temperature in and projected change in temperature for for the northern portion of Alaska. For the purposes of these maps, ‘winter’ is defined as December - February. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS3.1 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

Potential Evapotranspiration (PET): These data represent decadal mean totals of potential evapotranspiration estimates (mm). The file name specifies the decade the raster represents. For example, a file named pet_mean_mm_decadal_CCCMA_CGCM31_A1B_annual_2000-2009.tif represents the decade spanning 2000-2009. The data were generated by using the Hamon equation and output from CCCMA (also CGCM3.1), a third generation coupled global climate model created by the Canadian Centre for Climate Modeling and Analysis. Data are at 2km x 2km resolution, and all data are stored in geotiffs. Calculations were performed using R 2.12.1 and 2.12.2 for Mac OS Leopard, and data were formatted into geotiffs using the raster and rgdal...

Submerged aquatic vegetation (SAV) provides many critical ecosystem services, yet we lack basic information on SAV assemblages, biomass and diversity across expansive coasts such as the northern Gulf of Mexico (nGoM). This research investigated SAV along the nGoM from 2013-2015 examining (1) inter-annual variation in SAV assemblages and biomass across salinity zones and gulf coast eco-regions (Texas Mid-Coast, Texas/LA Chenier Plain, Louisiana Delta, MS/AL), (2) intra-annual variation in SAV assemblages and biomass across salinity zones, (3) response of two species, Ruppia maritima and Myriophyllum spicatum, to salinity and light regimes, and (4) estimated organic carbon stock and storage of SAV habitat soils across...
This project is part of an ongoing effort to develop and implement a landscape level decision support system (DSS) across the boundaries of Idaho, Washington, Oregon, and Montana. The project will strengthen public understanding in the use of objective and scientific fish and wildlife data and predictive modeling for purposes of developing geospatially-based landscape science to inform conservation and development actions. The project will inform, educate, and garner public and user support of the DSS upon its public release, aid in the development and use of the DSS web interface based on customer input and preferences, and provide communications strategies, tools, messages, forums, and feedback for improving public...

One of the major challenges in understanding changes in coastal processes in western Alaska is the lack of measured ocean data in the region. ​This project leverages existing human resources, and physical and computational infrastructure to collect and disseminate oceanographic observations in the Bering Sea. From instrument restoration, transport and deployment, through data streaming, recovery and dissemination, this project considers the end to end supports necessary to gather, promote, and serve oceanographic data along Alaska’s Western coast. Real‐time sea‐state conditions directly benefit emergency managers and local communities, particularly in dealing with small craft hazards and predicting storm surges...
Activity 1. Quantify viability of corridors using temporal sampling: past, present, future. As large-scale wind patterns change, the viability of flyways in the Pacific hemisphere is likely to change. This project will evaluate the tail/headwind components for flight routes from Alaska to sites in the South Pacific (documented godwit and curlew flight tracks) by sampling 50-year timeslices to determine whether the present climatology is more or less favorable than the past (paleoclimate) periods or the projected future (late 21st century). The project will determine whether other flight corridors may have been more advantageous in the past or future than during the present period.Activity 2. Assessment of optimization...
