Through this Dear Colleague Letter (DCL), the National Science Foundation's (NSF) Section for Arctic Sciences (ARC) of the Office of Polar Programs announces its interest in proposals to repurpose a subset of stations of the Alaska Transportable Array (http://www.usarray.org/researchers/adopt).

ARC recognizes the potential value of the Array to support observations of long-term environmental change of the Arctic. This DCL encourages proposals to modify and operate a network of stations with a view to provide long-term environmental observations.
