It is clear that dramatic changes are affecting the Arctic, and that Arctic changes impact the mid-latitudes. SEARCH (Study of Environmental Arctic Change) is an interagency science program which highlights the importance of recent changes in the Arctic on mid-latitude climate impacts. The complex suite of interrelated pan-Arctic changes have been identified in the SEARCH science plan by the name "Unaami", based on the Yup'ik word for "tomorrow".

The Unaami Data Collection, consistent with the SEARCH Science Plan, is a carefully selected, diverse set of over seventy-five multidisciplinary time series which quantify the complex, interrellated, pan-Arctic changes. This unique collection of Arctic change time series include good geographic coverage of the northern polar regions across diverse disciplines, including fisheries, biological, terrestrial, oceanic, sea ice, atmospheric and climate index data, from 1970 to the present. This time period includes the major atmospheric change noted near 1989. Although some of these data were already publically available, much of the data, especially biological data, was held by different institutions or individuals.

The web site "Unaami Data Collection: Quantifying Arctic Change" makes this unique collection of carefully selected diverse Arctic time series, and our analyses of these time series, easily and freely available to the scientific research community.
