SEARCH : Study of Environmental Arctic Change

Observing Change

The SEARCH Observing Change component focuses on observing and documenting arctic environmental change. Types of observing change research activities include: data rescue; improvement of observation density, co-location, and integration; improvement of coverage to close observation gaps; development of optimal observation and sampling strategies; observations of key processes and studies of feedbacks; acquisition of paleo-data over critical time periods; development of networks; development of data archival and distribution systems; and utilization of innovative and effective technology.

The major contribution to the SEARCH Observing Change component is NSF's Arctic Observing Network.

Arctic Observing Network Draft Position Paper

Input Requested for AON Position Paper
SEARCH requests input on a draft position paper on issues related to the design and implementation of an integrated AON. Drafting of this position paper was led by Craig Lee, chair of the SEARCH Observing Change Panel (OCP), with input from both the OCP and SEARCH SSC. The four-page paper represents a synthesis of discussions within SEARCH over the last year and builds on past SEARCH-AON community events and workshops. Key issues addressed in the paper include governance, network integration, and sustained funding. The draft paper is below, in both PDF and MS Word versions.

Deadline for Input: Friday, 21 November 2014

Send your input to: aon_input [at] arcus [dot] org. You can send your edits using "track changes" in the MS Word version, comments in the PDF version, or in email text.

If you have questions about the paper, please contact Craig Lee, Chair of the SEARCH OCP, at: craig [at] apl [dot] washington [dot] edu or Olivia Lee, University of Alaska Fairbanks, at: oalee [at] alaska [dot] edu

Arctic Observing System Framework

21 January 2014: SEARCH has developed a 5-page summary white paper on a potential implementation framework for a sustained US Arctic Observing System. The summary white paper includes discussion of how to set priorities, strategy, tactics, and operational implementation. A longer description of the framework is forthcoming.

About AON

AON is an integral part of the SEARCH program, as an NSF initiative growing out of the International Polar Year (IPY)to improve observational capabilities in the Arctic and leave a long-term legacy for the benefit of science and society. AON data will contribute to scientific research leading to (1) increased knowledge and understanding of the regional and global causes and consequences of present-day environmental arctic change, (2) scenarios for and prediction of the course of future arctic change and its regional and global consequences, and (3) the development of adaptive responses to arctic change.

AON currently consists of 51 projects funded by the NSF Office of Polar Programs. The AON projects fall into the following SEARCH Implementation Plan categories: Atmosphere; Ocean and Sea Ice; Hydrology/Cryosphere; Terrestrial Ecosystems; and Human Dimensions.

The Cooperative Arctic Data and Information Service (CADIS) supports AON by providing portal for data discovery, provide near-real-time data delivery, a repository for data storage, and tools to manipulate data.
