Title:

Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating and Drying Research (DryPEHR): Half-hourly soil moisture and temperature data, 2010-2018

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 warmign 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 achieve 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 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 and summer warming, drying, and control treatment plots at DryPEHR.

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.

Methods

Data were collected using DC half-bridges (gravimetric water content, 0-5 cm), Campbell Scientific CS616 or CS615 water content reflectometers (volumetric water content, 0-20 cm), and type-T thermocouples (soil temperature at depth 5, 10 20 and 40 cm). Data were recorded and stored to Campbell CR1000 datalogger.

Description:

corrections

Temperatures gaps in the data were filled using a similar sensor with best fit linear regression. Starting September 2012 Temperatures were corrected for dowel movements casued by soil freezing. Soil moisture data is for growing season only (May 1st through Sept 30th) and were site calibrated. On August 2014 soil sensor dowel were replaced.

additional

Data were collected using DC half-bridges (gravimetric water content, 0-5 cm), Campbell Scientific CS616 water content reflectometers (volumetric water content, 0-20 cm), and type-T thermocouples (soil temperature).
