- the

- Unaami

- data collection

- This data collection is an activity of the SEARCH Project Office and was supported by the NSF Arctic Systems Science program.  Information technology support was provided by NOAA ESDIM.

## Background

- from the U.S. Arctic Research Commission

- The Arctic remains one of the least explored, studied and understood places on earth
- Change in the Arctic may play a substantial role in climate change throughout the globe.
-  Global change, particularly climate change may have its most pronounced effects in the Arctic

## “...a complex suite of significant interrelated, atmospheric, oceanic, and terrestrial changes has occurred in the Arctic ....”

“... given the name Unaami... based on the Yup'ik word for ‘tomorrow’ ....” 

- “... given the name Unaami... based on the Yup'ik word for ‘tomorrow’ ....”

- Unaami

- from the Science Plan for the inter-agency Arctic program Study of Environmental  Arctic Change (SEARCH)

## The Unaami Data Collection

- Carefully selected diverse collection
- Over 80 time series which quantify  the complex, inter-related, pan-Arctic changes
- Good geographic coverage of northern polar regions
- Across diverse disciplines
- Fisheries, biological, terrestrial, oceanic, sea ice, atmospheric and climate index data
- From 1970 to the present

- Quantifying Arctic Change
