Title:

Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating and Drying Research (DryPEHR): Seasonal water table depth data, 2011-2021

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

This drying and warming experiment addresses the following questions: 1) Does ecosystem drying, warming and permafrost thaw cause a net release or uptake 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? 3) How do drying and warming affect plant communities and ecosystem properties? We are answering these questions using a combined warming and drying experiment (DryPEHR), which is situated with the Carbon in Permafrost Experimental Heating Research (CiPEHR) project and located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. Warming treatment here refers to growing season air temperature warming (~1C) using open top chambers (OTC) combined with soil 'warming' using snow fences during the snow covered months. Drying is achieved using an automated pumping system that lowers the water table in the dry plots. Soil warming began in 2008; OTCs and drying in 2011. This data includes water table depth measurements collected from the drying experiment (dry and control) at DryPEHR and winter warming and control treatment plots at CiPEHR for the ice-free period of 2011-2020.

Methods and protocols used in the collection of this data package

Description:

Experimental Design

The DryPEHR project is adjacent to the Eight Mile Lake (EML) watershed and EML natural thaw gradient, and is situated in the northern foothills of the Alaska Range. Permafrost temperature has been monitored annually on a gentle north-facing slope at this site in a 30-m-deep borehole that was installed in 1985. Warming treatment here refers to growing season air temperature warming using open top chambers (OTC) combined with soil insulation using snow fences during the snow covered months. Drying is achieved using an automated pumping system that lowers the water table in the dry plots. Soil warming began in 2008; OTCs and drying in 2011. PLEASE NOTE that the control (no drying or warming treatment) for DryPEHR comes from the CiPEHR treatment and is thus identical to the CiPEHR WW and SW control. Ie: DryPEHR plot A = CiPEHR plot 2 and DryPEHR control water wells = CiPEHR control water wells.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. The water dynamics driven by landscape position are difficult to control via experimental pumping and the Control/Dry treatment designations may therefore not be accurate qualitative descriptors. For 2019, a subset of the original wells were measured from June-September and a few new wells were added.

Methods

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).
