The Climatology, Hydrology and Paleo-Environmental Lab (CHAPEL)


Alex Pace's (PhD student) presentation at the December 2022 American Geophysical Union Fall Meeting:

The Climatology, Hydrology and Paleo-Environmental Lab (CHAPEL) was started in January, 2017.  Research in CHAPEL is focused on North American climatology and hydrology of the past 2000 years, the present and the near future. Our goal is a better comprehension of decadal-to-centennial climate variability, just beyond the scale of instrumental records, yet vital for our understanding of regional climate and hydrology, anthropogenic global warming impacts, and water management for infrequent extremes, such as sustained droughts and floods.

We use a wide variety of methods and approaches. For paleoclimate and paleo-hydrology reconstructions, we use tree-rings, pollen preserved in lake sediments, and other biological and physical proxies from lake sediments (i.e., diatom, charcoal, grain size, megnetic susceptibility, and varved sediment analysis). Research tools that we use for modern and near-future projected climatology and hydrology include: instrumental climatological and hydrological databases and archived GCM and RCM runs. Our research is heavily statistical, and methods used include multivariate statistics, time series analysis, Monte Carlo techniques and regression analysis.

CHAPEL is presently completely equipped for tree-ring based climate reconstructions, including extensive lab space, Windows computers, dissecting microscopes, WinDENDRO measuring software and other tree-ring software, a LA2400 Calibrated Color Optical scanner (2400 dpi resolution) and field equipment. It is also equipped for pollen based paleo-environmental reconstructions with two Leica DM2500 compound microscopes with cameras. Additionally, CHAPEL is equipped for sediment charcoal analysis to reconstruct forest fire frequencies with a Leica M80 dissecting microscope and WinSEEDLE image analysis software.

I collaborate closely with Professor Matthew Peros (CRC Tier II Chair) of Bishop’s University. We have full access to his extensively equipped paleo-environmental research laboratory

Jeannine-Marie St-Jacques (Ph.D. Queen's, 2007)
Associate Professor 

Jeannine-Marie St-Jacques received a PhD in Biology, specialty in environmental science, from Queen’s University in 2007 and joined Concordia’s Department of Geography, Planning and Environment in 2017. She holds master’s degrees in botany and mathematics. After her PhD, she worked for nine years as a Research Associate at the Prairie Adaptation Research Collaborative, University of Regina. Dr. St-Jacques’ expertise is in paleoclimatology, climatology and hydrology. Dr. St-Jacques is funded by NSERC. She collaborates with a broad spectrum of colleagues and students, who have expertise in environmental studies and sciences, climatology, climate modeling, botany, geology, statistics, aquatic ecology and Indigenous studies.
