Smoking Hills Peat Monolith 2017 Collection

The peats were extracted using a saw and/or spade and by hand. Various study sites were selected based on opportunities for collection provided by other on-going work (bedrock mapping in the NWT and an on-the-land Inuit Qaujimajatuqangit camp in Nunavut). Collection in Nunavut also served as experiential learning in the case of the IQ camp. Peats were collected because the ecohydrological future of high-latitude peats in response to 21st century warming is poorly known and these peatlands are important for global carbon dynamics. The peats were sent back to laboratories in Calgary (Geological Survey of Canada) and then distributed to the University of Alberta (under the collaboration of Professor William Shotyk) where a sub-sampling protocol for the peat monoliths has begun in the ultra-clean SWAMP laboratory. The protocol involves trimmed edges (to minimize contamination) and sub-sampling for pH, EC, ash content, AIA, ASA; an frozen archive; 4 cm3 aliqouts for HAWK pyrolysis (to evaluate organic matter constituents); 4cm3 aliquots for Hg analysis; aliquots for organic contaminants; and aliquots for gamma spectrometry (210-Pb dating), elemental analysis by ICP-MS, light stable isotopes, and acid digestion (sequential, as needed); 2cm3 aliquots for palynological analysis (pollen and spores), plant macrofossils, and 14C AMS age dating; and analysis of testate amoebae upon which quantitative depth to water table reconstructions may be generated. Five peat monoliths are currently being processed at the University of Alberta (expected completion by March 31, 2020). Analysis of the sub-samples will be on-going between April 01 2020 and March 31 2024.
