Title:Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): Seasonal water table depth data, 2012-2019
Alternate Identifier:DOI PLACE HOLDER
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 includes water table depth measurements collected from winter warming and control treatment plots at CiPEHR for the ice-free period of 2012-2019.

Description:

Experimental Design

The study site at the Eight Mile Lake (EML) watershed is located in the northern foothills of the Alaska Range. While permafrost thaw can sometimes result in water ponding, depending on local topography, this landscape consists largely of relatively well-drained uplands. The CiPEHR experiments were established in 2008 to complement research along a natural permafrost thaw gradient, at an adjacent site. At the permafrost-thaw gradient site permafrost temperature has been monitored annually in a 30-m-deep borehole since1985, before the permafrost started to thaw. There are two experimental warming treatments at the CiPEHR project: Winter warming (WW) increases soil temperature and ground thaw using snow fences; Summer warming (SW) increases growing season air temperature using open top chambers. The warming treatments are applied in a blocked split-plot design to evaluate the seperate and combined effects of winter and summer warming. Permafrost thaw induced by experimental soil (winter) warming has caused subsidence within the footprint of the experiment. Heterogeneous microtopography as a result of subsidence has caused variable moisture conditions with some plots periodically or continuously flooded during the thawed period and some plots remaining dry. This data set includes water table depth measurements collected from winter warming and control treatment plots at CiPEHR. For 2019, a subset of the original wells were measured from June-September and a few new wells were added.

Methods

FIELD: Water table depth in relation to the soil surface was measured three times per week until 2012 and only once per week in 2013 onward throughout the snow-free period in water wells that were installed at each fence in May 2009. Water table depth data are presented during the time period when wells were ice-free (~ mid-June through September). LAB: No specific lab methods recorded.
