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.

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.
A new webpage developed through SEARCH provides access to early-release datasets on ice thickness, snow depth, and ice characteristics collected in March/April of 2012 in the North American Arctic. The webpage is available at:
http://www.arcus.org/search/seaiceoutlook/ice-thickness-data.
Data were obtained by different projects, centering around the National Aeronautics and Space Administration's (NASA) Operation IceBridge survey flights, with key contributions from NSF-funded activities of the interagency Arctic Observing Network (AON). The goal of this early release of preliminary data is to provide timely information to the international sea-ice prediction community for initialization of seasonal ice predictions, including those for the SEARCH Sea Ice Outlook.
The data release includes contributions from different U.S. federal agency, private industry, and international partners to provide timely sea-ice data of broader relevance in the North American Arctic. The data acquisition reflects collaboration with local government and co-management boards to avoid interfering with subsistence hunting activities and provide information of relevance to coastal communities.
Datasets available through this webpage include:
- NASA Operation IceBridge Quicklook Data
- Seasonal Ice Zone Observing Network (SIZONet) Airborne Electromagnetic Induction Ice Thickness Surveys Quicklook Data
- Fugro Earth Data, Inc. Airborne P-band Synthetic Aperture Radar (SAR) Survey Quicklook Data
- Naval Research Laboratory Tandem Flight Airborne LiDAR and Radar Altimeter Surveys
- SIZONet Surface-based EM Survey Data (Barrow Landfast Ice Region and Drifting Multiyear Ice Site)
- Cold Regions Research and Engineering Laboratory (CRREL)-Arctic Observing Network Ice Mass-balance Buoy Data
- SIZONet Snow and Ice Property Measurements
