About
Witness the Arctic provides information on current arctic research efforts and findings, significant research initiatives, national policy affecting arctic research, international activities, and profiles of institutions with major arctic research efforts. Witness serves an audience of arctic scientists, educators, agency personnel, and policy makers. Witness was published biannually in hardcopy from 1995-2008 (archives are available below) and is currently published online 3-4 times annually, depending on newsworthy events.
Archives
With the Spring 2009 issue, ARCUS changed the format of Witness the Arctic. To provide more frequent updates and reduce printing and mailing costs and associated environmental impacts, the newsletter is now distributed online in three or four shorter issues per year, depending on newsworthy events.

The Department of Physics and Astronomy has a strong program in theoretical and experimental space physics (http://www.dartmouth.edu/~physics/research/space.physics.html). Faculty members Jim LaBelle, Kristina Lynch, and Robyn Millan have a long history of rocket and balloon studies of the solar wind and its interactions with the Earth's magnetosphere. In the Arctic, these interactions appear as the aurora borealis or "northern lights." Instrument packages have been sent into the upper atmosphere from many northern locations including Alaska, Sweden, and Canada. Similar work has also been conducted in Antarctica.
