Title: The impact of warming on ecosystem carbon balance: Half-hourly soil moisture and temperature data from the CiPEHR project, Healy AK, 2008-2013

Abstract: The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This data set includes half-hourly values of surface moisture content (gravimetric, 0-5cm), depth-integrated soil moisture (volumetric, 0-20 cm), and soil temperature in winter warming, summer warming, and control treatment plots at CiPEHR.

Site References: EML -- Tussock tundra at treeline with permafrost thaw and thermokarst. This site is in the Eight Mile Lake Watershed, west of the town of Healy on Stampede Road, Interior Alaska. This area contains three sites on a permafrost thaw gradient and a nearby experimental snow fence manipulation.
