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.

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...

New version for 2023. This collection consolidates the IGS Oil and Gas database, documents, logs, and LAS files, superseding collections “Collection of Well logs from Idaho” and “Idaho oil and gas well data.” These files include information on current and historical oil and gas exploration wells in Idaho provided by companies to the Oil and Gas Commission from 1903-2022. This data was transferred to the Idaho Geological Survey in 2009 from the Idaho Department of Lands, who regulates and maintains data for recent/current oil and gas exploration in Idaho. The Idaho Geological Survey maintains files on two hundred fourteen oil and gas wells in the state. Some files contain drilling service reports, geophysical logs,...

These rasters that represent estimated potential evapotranspiration (mm). Data were generated by using the Hamon equation and air temperature projections from the CCCMA model under the A1B emission scenario.
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 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...

These rasters represent estimated potential evapotranspiration (mm). Data were generated by using the Hamon equation and air temperature projections from the ECHAM5 model under the A1B emissions scenario.
This data set represents an updated Ecological Subsection Map for Northern Alaska. This 2012 revision focused on completing the incompletely mapped portion of the southern NPRA, improving mapping of glacial and outwash deposits within the Brooks Foothills, and improving consistency with existing surficial and bedrock geology maps in northern Alaska. The revisions resulted in 525 ecological subsections, nested within 55 ecosections and 12 ecoregions covering 411,781 km2. Attributes for the polygons include information on physiography, generalized geology, lithology, and referenced information sources. Description of attributes is provided in the map documentation report. The dataset can be downloaded from catalog.northslope.org.

Desert LCC Base Maps and Data describe the physical and cultural geography of the Desert Landscape Conservation Cooperative. These products include the Desert LCC vector boundary available as a shapefile and KML, as well as print-quality graphic design files for thematic maps including Watersheds, Land Cover, Vegetation and a Base Map. The scale of the maps is 1:2,500,000. About the Desert LCC Region: Forty percent of the Desert LCC area lies in the United States and the remaining 60 percent, in Mexico. The total DLCC area is 536,955 square miles or 1,390,713 square kilometers. To explore data per Desert LCC priorities, visit the Conservation Planning Atlas.
