Study Site: Peace River, Alberta
Purpose: Boreal peatlands serve as long-term carbon (C) sinks and a significant source of methane (CH4) to the atmosphere. However, peatlands are threatened by both natural and anthropogenic disturbances, resulting in potential release of large amounts of C to the atmosphere. Linear disturbances, such as seismic lines for geologic exploration, constitute the largest area of disturbance in boreal Canada. The impact of seismic lines on peatland C cycling is not well understood, although physical changes in topography and lack of tree re-establishment are well-documented. This study used the closed chamber technique to measure growing season understory CH4 fluxes on the footprint of the seismic line disturbance and in adjacent intact peatlands and assessed environmental controls on CH4 dynamics across a treed fen and two treed bogs near Peace River, Alberta, Canada.
Abstract: Instantaneous measurements of methane flux at plots on seismic lines and adjacent undisturbed peatlands alongside concurrently measured gross ecosystem productivity, water table and soil temperature data (2024-06-13)
