Objectif(s): The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change.
Description du projet: The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change. Three transects with 31 sampling locations will be set up. At each location a Time Domain Reflectometry (TDR) probe and thermocouple will be installed and continuously monitored by a solar powered data collection system. Gas flux will be measured using a small portable chamber. Approximately 500 g of soil will be sampled from each transect and analyzed. Surrounding soil is brushed into the resulting hole afterwards. Short term incubations may be set up on site. Researchers will be on site from mid-June to mid-July and return in late August. This research is a continuation of the project by Steven Siciliano. Results will be forwarded to the Aurora Research Institute. This group is participating in the CiCAT IPY projects outreach activities, including delivering a workshop to the ACUNS student conference. The group will participate in the Daring Lake Research Station Science Camp if there is interest. Fieldwork will be conducted from May 26 to August 31, 2008 at Daring Lake Terrestrial Ecological Research Station (64.83 N, 111.63 W) and upland tundra (64.868N, 111.575 W).
