This dataset includes 800m resolution long-term average estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 2000-2013 and annual estimates for the individual years. These estimates were developed with a new empirical regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1434 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO). Irrigated water quantities reported in the 2000, 2005, and 2010 USGS Water Use datasets are also incorporated as effective additional precipitation. The contributing input datasets...

The Gap Analysis Program (GAP) is an element of the U.S. Geological Survey. GAP helps to implement the Department of the Interior’s goals of inventory, monitoring, research, and information transfer. GAP has three primary goals: Identify conservation gaps that help keep common species common; Provide conservation information to the public so that informed resource management decisions can be made; and Facilitate the application of GAP data and analysis to specific resource management activities. To implement these goals, GAP carries out the following objectives: Map the land cover of the United States Map predicted distributions of vertebrate species for the U.S. Map the location, ownership and stewardship...

This collection is comprised of digital, slide and print photographs taken during engineering geology, energy and minerals resource related field projects from 1970-2017. Eight percent of the individual items associated with this collection are energy resource related field photos taken by Charles (Gil) Mull and Rocky Reifenstuhl. The remainder of the records are mineral resource and engineering geology field photos. These photos document field sites, geologic features, landscapes and landforms from the various areas of Alaska. At the collection level for energy related field photos, there are approximately 43,000 photos and slides that still need to be culled, documented and archived. 98% of the photos are in digital...

The Core Research Center (CRC) was established in 1974 by the USGS to preserve valuable samples of the Earth’s subsurface for use by scientists and educators representing government, industry, and academia. The CRC collections include full-diameter rock cores, slabbed cores (cut in half longitudinally), well cuttings, thin sections, and associated analytical data. A majority of the material was donated to the CRC by private industrial companies, although some cores and cuttings were collected by the USGS and other government agencies. Rock cores were collected from roughly 9,500 drilled borehole locations representing approximately 610,000 meters (2 million feet) of subsurface strata in 35 states. Many of the boreholes...

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...

The Climate Commons is the California LCC’s starting point for discovery of climate change data and related resources, information about the science that produced it, and guidance for applying climate change science to conservation in California. One of the services the Commons offers is a collection of articles introducing and explaining key concepts relating to climate change and conservation in California, helping resource managers get up to speed with this science and find important resources that they need to incorporate climate science into their conservation planning. Topics included: Scenario planning, climate-smart conservation, vulnerability assessment, sea-level rise, a summary of the most current climate...
The Upper Mississippi River Basin Data Portal (UMRBDP) supports the research, science and monitoring missions of the USGS's Midwest Region (MWR) and others by allowing the users to discover, visualize, share, and retrieve geographic information and data sets related to the Upper Mississippi and other large rivers in the MWR.

Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited. The development of robust and transportable models requires access to numerous inventories of ground failure triggered by earthquakes that span a broad range of terrains, shaking characteristics, and climates. We present an openly accessible, centralized earthquake-triggered ground-failure inventory repository in the form of a ScienceBase Community to provide open access to these data, and help accelerate progress. The Community hosts digital inventories created by both USGS and non-USGS authors. We present...

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...
