Take 2—USGS Re-releases The Alaska Geochemical Database
An Improved version for Speed and Efficiency of Use
The publication "Alaska Geochemical Database Version 2.0 (AGDB2)—Including "Best Value" Data Compilations for Rock, Sediment, Soil, Mineral, and Concentrate Sample Media" contains new compilations of geochemical data in which each geologic sample has one "best value" determination for each analyzed chemical species. AGDB2 was created and designed to compile and integrate geochemical data from Alaska in order to facilitate geologic mapping, petrologic studies, mineral resource assessments, definition of geochemical baseline values and statistics, environmental impact assessments, and studies in medical geology. This relational database, created from the Alaska Geochemical Database (AGDB) that was initially released in 2011, serves as a data archive in support of present and future Alaskan geologic and geochemical projects. It contains data tables in several different formats describing historical and new quantitative and qualitative geochemical analyses. The new Data Series—containing a pamphlet, metadata files and data files—is available at http://pubs.usgs.gov/ds/759/. Also see technical announcement at USGS News Room.

New Fact Sheet Provides Information on New and On-going Research Related to Wildlife Disease and Environmental Health in Alaska
Wildlife and environmental health research at the USGS Alaska Science Center focuses on emerging wildlife diseases, movement and transmission of pathogens between continents and within Alaska, and the impacts of disease to wildlife populations. Information from this research will inform decision-making by wildlife management and human health agencies.
Interagency Working Group Calls for Integrated Management and Planning for a Rapidly Changing Arctic
