Synthesis of climate model downscaling products for the southeastern United States: Downscaling translates large-scale climate information to the local scale. There are several techniques for handling this process; recently, several downscaled climate products have been produced by government and academic researchers. Ecologists, conservation scientists, and practitioners require such local guidance to evaluate adaptation and conservation strategies. However, the large number of methods involved, different downscaling approaches, resolutions, time periods, and focal variables limits the ability of these users to form meaningful conclusions and evaluate the results of adaptation strategies. To address these issues, this project will summarize the methods used for downscaling, identify the metrics most appropriate for evaluation of climate model skill and usability for the ecological and conservation communities in the southeastern US, and begin a longer-term effort to evaluate the range of downscaled climate products over this geographic region.

Genetics Provide New Hope for Endangered Freshwater Mussels: A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study. Local population losses in a river may not result in irreversible loss of mussel species; other mussels from within the same river could be used as sources to restore declining populations.

TRB Images: Photos of the natural resources and partners working to protect those resources in the Tennessee River Basin.

Tennessee River Basin Aquatic Units Map: This map displays the upper, mid, a lower Tennessee River watersheds along with the boundary for the UTRB Imperiled Aquatic Species Strategy and the Appalachian LCC overlaid on the National Geographic base map.

Monthly carbon dioxide levels hit new milestone: NOAA scientists reported that in March 2015 the monthly average global carbon dioxide level went above 400 parts per million for the first time.

Public Data Repositories: Provides links to sites containing maps and geospatial data which can be viewed or downloaded for use within a desktop GIS environment. These sites are from a variety of resources throughout the nation.

USGS Global Change Monitoring Portal: The Global Change Monitoring Portal (GCMP) is a project of the DOI Southeast Climate Science Center and aims to support the efforts of multiple federal, state, and other organizations by providing a centralized, comprehensive catalog of observational networks associated with aquatic and terrestrial ecosystems in the southeastern United States. The Southeast GCMP region of interest encompasses all or part of several Landscape Conservation Cooperatives (LCCs) in the southeastern US and Caribbean. Information about existing and historical observational networks and monitoring sites was compiled into a relational database. Programs and sites are classified according to: type of media being monitored (air, land, water), the general type of measurements that are made (biological, chemical, physical), and the general type of parameters that are measured (e.g., fauna) within a particular measurement type (e.g., biological).

NOAA National Center for Environmental Information: The National Center for Environmental Information is the world’s largest provider of weather and climate data. Land-based, marine, model, radar, weather balloon, satellite, and paleoclimatic are just a few of the types of datasets available. Detailed descriptions of the available products and platforms are available on the website.

The Nature Conservancy Conservation Gateway: Spatial data and maps are a crucial element in conservation science, and support meaningful contributions to conservation. Analyses require consistent, regional-scale spatial data and associated products. On this page, you can download the data The Nature Conservancy has used in their large-scale analyses.

USFWS Geospatial Services: Geospatial data and services are critical elements needed to meet the mission of the U.S. Fish and Wildlife Service (USFWS). Geographic Information Systems (GIS), Global Positioning Systems (GPS), and remote sensing are the primary elements which fall under the geospatial data and services umbrella. This site was created to enable the USFWS to be effective in managing geospatial data resources and technology to successfully deliver geospatial services in support of the Service’s mission.

U.S. Census: TIGER = Topologically Integrated Geographic Encoding and Referencing TIGER products are spatial extracts from the Census Bureau's MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas. The Census Bureau offers several file types and an online mapping application.

WorldClim: WorldClim is a set of global climate layers (climate grids) with a spatial resolution of about 1 square kilometer. The data can be used for mapping and spatial modeling in a GIS or with other computer programs

U.S. Energy Information: Datasets on Energy Sources within the United States. Covers Coal, Natural Gas, Oil Wells, Electricity and Nuclear, and Renewable Sources.

The National Atlas: All raw data contained in the National Atlas is available for downloading including everything from agricultural census data, presidential election results, airports, railways, glaciers, arsenic content in groundwater, and much more.
