Sea Ice Outlook Reports

The Sea Ice Outlook, an activity of the Sea Ice Prediction Network and a contribution to SEARCH, produces reports in June, July, and August containing a variety of perspectives on Arctic sea ice—from observations of current conditions, to advanced numerical models, to qualitative perspectives from citizen scientists. A post-season report provides an in-depth analysis of factors driving sea ice extent this summer as well as explore the scientific methods for predicting seasonal ice extent.

Sea Ice for Walrus Outlook

The Sea Ice for Walrus Outlook (SIWO), a contribution to SEARCH, is a resource for Alaska Native subsistence hunters, coastal communities, and others interested in sea ice and walrus. The SIWO provides weekly reports from April through June with information on sea ice conditions relevant to walrus in the Northern Bering Sea and southern Chukchi Sea regions of Alaska.

2015 Permafrost Article Published in Nature

Led by Ted Schuur, Permafrost Action Team Chair, and incorporating many previous and ongoing synthesis activities of the Permafrost Carbon Network, the Climate Change and the Permafrost Carbon Feedback review article was published by Nature in April of 2015 (doi:10.1038/nature14338). The review outlined the current state of knowledge about the impact of thawing permafrost carbon on climate in a future warmer world.

Listen to Sue Natali, one of the Nature article's co-authors, discuss the significant role that Arctic permafrost carbon release plays in global climate change on PRI's Living on Earth program here.

2015 Arctic Observing Framework

The drafting of this proposed Arctic Observing framework was co-led by Hajo Eicken, chair the SEARCH Science Steering Committee (SSC), and Craig Lee, chair of the SEARCH Observing Change Panel (OCP), with input from the SEARCH Science Steering Committee, SEARCH Observing Change Panel and SEARCH Science Office. The paper proposes an Integrated Arctic Observing System organized though a framework of “Arctic Services” to better combine the different roles that AON would play for agencies supporting basic research, those with operational missions, as well as non-governmental entities and stakeholders. The full framework document as well as a summary brief are provided below.

2015 Arctic Observing Network Position Paper

This brief position paper was led by Craig Lee, chair of the SEARCH Observing Change Panel (OCP), with input from both the OCP, SEARCH SSC, ARCUS, and via a call for input from the broader community. The paper represents a synthesis of discussions within SEARCH over the previous year and builds on past SEARCH-AON community events and workshops. Key issues addressed in the paper include governance, network integration, and sustained funding. More information: http://www.arcus.org/search-program/aon

This report is a synthesis of community-wide planning discussions before, during and after the SEARCH Implementation Workshop, which was convened to establish priorities for the next steps of the implementation of SEARCH. The report is meant to serve as a point of reference for immediate planning in preparation for the International Polar Year and for an Arctic Observing Network, and also to provide a perspective on SEARCH beyond the immediate needs and priorities.

Download the SEARCH Brochure (PDF - 1.4 MB)

SEARCH: The Study of Environmental Arctic Change, a brochure published by the Arctic Research Consortium of the U.S. for the SEARCH Interagency Working Group and the Interagency Arctic Research Policy Committee, is now available.

At the request of John Calder, head of the Arctic Research Office of the National Oceanic and Atmospheric Administration, and through the Cooperative Institute for Arctic Research (CIFAR) at the University of Alaska Fairbanks, ARCUS developed this short informational brochure to introduce the SEARCH program, a major new interagency arctic research effort, to a general audience.

Nine federal agencies with research interests and responsibilities in the Arctic will cooperate to carry out the SEARCH program. The SEARCH brochure is designed for use by agency representatives to present their research activities and the collaborative activities supported by SEARCH and to inform the public of the impact of SEARCH activities in assessing and understanding the scope of global climate change.

The brochure consists of four pages, featuring each agency's SEARCH activities and an overall description of the purpose, activities and plans for SEARCH. The brochure is available as a downloadable PDF from the ARCUS web site.
