This pilot project has initiated a long-term integrated modeling project that aims todevelop a dynamically linked model framework focused on climate driven changes tovegetation, disturbance, hydrology, and permafrost, and their interactions and feedbacks.This pilot phase has developed a conceptual framework for linking current state-of-thesciencemodels of ecosystem processes in Alaska – ALFRESCO, TEM, GIPL-1 – and theprimary processes of vegetation, disturbance, hydrology, and permafrost that theysimulate. A framework that dynamically links these models has been defined and primaryinput datasets required by the models have been developed.

The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

Layered geospatial PDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, boundaries, and other selected map features. This map depicts geographic features on the surface of the earth. One intended purpose is to support emergency response at all levels of government. The geospatial data in this map are from selected National Map data holdings and other government sources.
This project established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...

These raster datasets are 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. These data were generated by driving the GIPL model with a composite of five GCM model outputs for the A1B emissions scenario. 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...

The Northwest Boreal Landscape Conservation Cooperative (NWB LCC) is a partnership between agencies involved in land management across Alaska, Yukon, Northwest Territories, and British Columbia. The NWB LCC aims to coordinate science and support to decision makers for improving land management decisions. Knowledge gaps have been identified by the NWB LCC and are beginning to be filled. One of the priority information gaps is knowledge of the anthropogenic footprint currently on the landscape.The anthropogenic footprint is all the disturbance types made by various human activities, usually through some form of industrial development. Examples include roads, power lines, pipelines, and clear cuts among many others....

The western coastline of Alaska is highly susceptible to coastal storms, which can cause coastal erosion, flooding, and have other pernicious effects to the environment and commercial efforts. The reduction in ice coverage due to climate change could potentially increase the frequency and degree of coastal flooding and erosion. Further, estuaries and delta systems act as conduits for storm surges, so when there is less nearshore ice coverage, these systems could introduce storm surge into terrestrial environments unaccustomed to saline intrusion, flooding, or other alien biogeochemical factors.This project quantified the effect of reduced nearshore ice coverage on coastal flooding. The project developed a large...

The daily flight tracks of the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the plane’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the aircraft’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks thus include the aircraft’s flight to and from the airport base. The 29 track files are named TRMMDDYY_AIR.csv, where MM = month, DD = day, and YY = year.

The maps show baseline (1961-1990) average air temperature and projected air temperature for the decades spanning 2010-2039, 2040-2069, and 2070-2099. Temperature is expressed in both Celsius (у) and Fahrenheit (ц). Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1. data and maps for future time periods are based on a composite of projections from five GCMs (CCSM4, GFDL-CM3, GISS-E2-R, IPSL-CM5A-LR, and MRI-CGCM3) under the AR5-RCP 6.0.

This is a collection of GIF-format animations and PNG images that are suitable for presentations. These products include images for the baseline period (1961-1990) and images for each decade between 2010 and 2090. Baseline values are derived from Climate Research Unit (CRU) TS 3.1. or TS 3.1.01 data; values for future time periods are based on the SNAP 5-GCM composite under the AR5-RCP 6.0 and AR5-RCP 8.5. CRU and GCM data are provided courtesy of Scenarios Network for Alaska and Arctic Planning (SNAP).Air temperature is expressed in units of Celsius (у) and Fahrenheit (ц) and precipitation is available in units of millimeters (mm) and inches (in). Special note about animations: The first image of the animation...

These raster datasets represent output from the Boreal ALFRESCO (Alaska Frame Based Ecosystem Code) model. Boreal ALFRESCO operates on an annual time step, in a landscape composed of 1 x 1 km pixels, a scale appropriate for interfacing with mesoscale climate and carbon models. 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. Coverage of this dataset includes much of the state of Alaska (but does exclude Southeastern AK, Kodiak Island, portions of the Alaska Peninsula, and the Aleutian...

These maps show baseline (1961-1990) average total precipitation and projected change in precipitation for the decades spanning 2010-2039, 2040-2069, and 2070-2099. Precipitation is expressed in both millimeters (mm) and inches (in); projected change in precipitation is expressed as percent of baseline. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1.01 data and maps for future time periods are based on a composite of projections from five GCMs (CCSM4, GFDL-CM3, GISS-E2-R, IPSL-CM5A-LR, and MRI-CGCM3) under the AR5-RCP 6.0.

These raster datasets are output from the Geophysical Institute Permafrost Lab (GIPL) model and represent simulated active layer thickness (ALT) in meters averaged across a decade. These data were generated by driving the GIPL model with a composite of five GCM model outputs for the A1B emissions scenario. The file name specifies the decade the raster represents. For example, a file named ALT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated maximum depth (in meters) of thaw penetration (for areas with permafrost) or frost penetration (for areas without permafrost). If the value of the cell is positive, the area is underlain by permafrost and the cell value specifies the depth...
