SEARCH Implementation
SEARCH
Motivation
Axiom - The Arctic has been characterized in recent decades by a complex of significant, interrelated, pan-Arctic changes (Unaami).
Hypothesis 1 - Unaami is related to a spin up of the atmospheric Polar Vortex.
Hypothesis 2 - Unaami is a component of climate change.
Hypothesis 3 - Feedbacks among the ocean, the land, and the atmosphere are critical to Unaami.
Hypothesis 4 - The physical changes of Unaami have large impacts on the Arctic ecosystems and society.
Implementation
To test these hypotheses and help society deal with change requires a program long-term, large-scale observations, analysis, and modeling.

DQU: Detecting and Quantifying Unaami and Other Modes of Variability
Use paleoclimate, historical, archeological records as well as more recent observations to better define the scope of Unaami and its relation to other modes of variability.

LGC: Linkages and Global Coupling
Use modeling and analysis * to elucidate the connections between Unaami and global climate and the connections within the arctic system as they pertain to Unaami.
* use DQU, DMU, DTO, process studies as required

SEI: Social and Economic Interaction
Examine the interactions of the physical and biological elements of Unaami and the social and economic systems within the context of other forces of social change.
SOR: Social Response
Research social and economic adaptation to climate change in the past and apply research on Unaami to economic and social concerns in the future. Find ways to communicate the results of SEARCH to decision makers.
