About Us - The Purpose of SEARCH
The Study of Environmental
Arctic Change (SEARCH) is conceived as a broad, interdisciplinary
program whose core aim is understanding significant, interrelated
atmospheric, oceanic, and terrestrial changes that have been occurring
in the Arctic in recent decades. These changes are affecting virtually
every part of the arctic environment and is having repercussions on society.
There is evidence that the changes are connected with changes in atmospheric
circulation of the Northern Hemisphere, and there are indications that
these changes are indicative of greenhouse warming. It is unclear what
feedback processes on climate or ecosystems may be involved in the recent
changes, or what the long-term impacts may be.
The plans
for SEARCH have come about through two workshops. The first, in 1997,
explored evidence of change in the Arctic and is summarized in the Study
of the Arctic Change Workshop Report. A Second
Workshop produced a plan for SEARCH research activities and lead
to the development of a SEARCH
Science Plan.
The
SEARCH organization includes the community of arctic principal investigators
and funding agencies. The principal investigators are represented by the
SEARCH Science Steering Committee (SSC).
With National Science Foundation
Office of Polar Programs
support, the SEARCH SSC has been responsible for developing the Science
Plan. The funding agencies, under the auspices of the Interagency Arctic
Research Policy Committee (IARPC), have formed an Interagency
Working Group (IWG) for SEARCH to develop a funding implementation
plan. The SEARCH Project Office, also with funding by the NSFOPP,
has facilitated the work of the SSC and IWG and is responsible for this
Web site. The project office developed an IWG SEARCH Presentation
Kit that is excerpted here.
It describes important examples of recent changes in the Arctic and hypotheses
about these changes.
The SEARCH
strategy is conditioned in part by the knowledge that a number of long-term,
large-scale Arctic observing systems have disappeared or are in danger
of disappearing. The strategy includes four major activities:
- Long-term
observations to detect and monitor the environmental changes
- Modeling
to synthesize observations, test ideas about the coupling between
different components of Unaami, and to predict Unaamis future
course
- Process studies
to understand potentially important feedbacks
- Application
of what we learn to understanding the ultimate impact of the physical
changes on the ecosystems and societies, and to distinguish between
climate-related changes and those due to other factors such as resource
utilization, pollution, economic development, and population growth.
We visualize
that these activities will require an interdisciplinary, international
effort composed of many parts. The activities may be carried out by groups
wholly initiated and supported by SEARCH and by groups previously initiated
in the international community, such as the Arctic
and Subarctic Ocean Flux (ASOF) study.
