Adam is completing his PhD. Biology with a thesis project that investigates the microbial production of greenhouse gases from degrading palsas in the Hudson Bay Lowlands of Far North Ontario. He is co-supervised by Pascale and Nathan and is working in collaboration with Maara Packalen and Jim Mclaughlin of the Ontario Ministry of Natural Resources and Forestry. Adam was a WCS-Weston fellow in 2017-18, and his field work took place near Peawanuck, in Winisk First Nation Traditional Territory. His research will help understand how this area may respond to climatic change and what controls the emissions of methane and carbon dioxide from degrading palsa fields. Adam has previous research experience at the Northern Ontario School of Medicine in the field of remote sensing for environmental applications such as mapping and predicting cyanobacteria blooms.

Former team members
Chantae completed her M.Sc. Biology with a thesis project on investigates shrubification patterns and implications for nutrient cycling near Churchill, MB. Her thesis research included remote sensing, the final stages of a 10 year litter bag decomposition study in sedges and dwarf birch, and the characterization of soil microbial communities. Chantae was co-supervised by Nathan and Pascale and worked in collaboration with Kevin Turner (Brock University) and Paul Hazlet (NRCAN-CFS). Chantae‘s work increased understanding of the impacts of climatic change on vegetation cover and nutrient cycling in tundra environments located close to the forest-tundra transition. Chantae is now a medical student at the Northern Ontario School of Medecine.

Candice completed her B.Sc in Environmental Science with a specialization in Geography, and a certificate of geographic techniques. Her thesis project examined relations between land cover and the occurrence of near-surface permafrost near the community of Fort Severn, Ontario, where she conducted field work in summer 2017. Her work with satellite imagery and field data lead to the development of a map and a preliminary assessment of permafrost distribution near the community, which is located in the continuous permafrost zone of the Hudson Bay lowlands.

Emma pursued a BA in Geography with a minor in biology and a certificate in geographical techniques (GIS, air photo interpretation, etc) at Laurentian. Her thesis project aimed to describe and assess beaded stream distribution in the valleys of the Blackstone and East Blackstone rivers near Chapman Lake, in central Yukon. Emma presented her thesis work at the Canadian Association of Geographer Annual Meeting and graduated in 2017. Emma went on to pursue a MSc in Coastal and Marine Science at the University of Algarve, in Portugal, and worked on methane emissions from open system pingos in Svalbard for her thesis.

Mary investigated the effects of increased active layer moisture on permafrost sustainability in Arctic and subarctic peatlands, to help differentiate conditions where increased moisture leads to an increased thermal offset from conditions where increased moisture may lead to a deepening of the active layer and permafrost degradation.

Nathan is a second year student pursuing a degree in Outdoor Adventure Leadership (ADVL) with a minor in Geography at Laurentian University. He completed his ADVL internship with the Permafrost Research Laboratory in summer 2016, providing logistical support for Emma’s thesis research in the Blackstone Uplands of central Yukon. Through his work Nathan assisted with the planning and implementation of camp and transportation logistics, the investigation of safety concerns relevant to the study area, and permafrost data collection activities in the field. Nathan is an experienced hiker and avid rock climber, and it was great to have him on our team to facilitate field logistics.
Erin Gordey worked as a research assistant at the permafrost research laboratory. She built a scale model to mimic frost penetration and ice segregation in fine grained sediment, assessed organic matter and carbon content in permafrost samples, and helped us to continue improve the set-up of our lab and work space. Erin is a graduate of the Laurentian University Geography Program, and has extensive experience working (and living) in Arctic and northern communities. Since fall 2017, she is pursuing a MA in Indigenous Relations at Lauentian University.
Krystal worked as a research assistant at the permafrost laboratory. She used GIS to assist with the calculation of thermokarst lakeshore erosion rates in the tundra of Old Crow Flats. Krystal also worked on a circumpolar inventory of tundra lowlands with thermokarst lakes, and helped setting-up the new permafrost laboratory. She left us in fall 2016, to attend Ryerson University, where she completed a Masters of Spatial Analysis.
