Geneviève Potvin, GIS Specialist and PhD student
Department of Applied Geomatics, University of Sherbrooke
As a part-time GIS Specialist, Geneviève will work on the development of the LakePulse Web Atlas, in collaboration with the Database Specialist. The vast datasets gathered by LakePulse will be presented in a user-friendly manner for a broad range of end users.
Geneviève transitioned to a part-time role as a GIS Specialist for LakePulse after beginning her doctoral studies within the Network in optics and remote sensing in 2018.
She initially worked on geomatics analyses for LakePulse, such as for the LakePulse Survey and the pan-Canadian watershed analysis. For the watershed analyses, over 75,000 lake watersheds were delineated and a human impact index was developed.
PhD research project
Bio-optical algorithms for optical water quality parameters for past, current and future satellite sensors
My PhD project will focus on the inversion of water reflectance to retrieve water quality parameters. I will process the data from the optical packages; study mass-specific IOPs; test and develop bio-optical algorithms for water quality parameters for satellite sensors with different optical characteristics (e.g., Landsat 8 and Sentinel-2); apply the algorithms to atmospherically-corrected satellite images; and develop a health index based on optical water quality time series.
PhD project start and finish dates: 2018 to 2021
Supervisor: Yannick Huot (Université de Sherbrooke)
LakePulse survey sampling 680 lakes across Canada
Summer 2018: Geneviève will be the team leader for the Purple Team sampling lakes in Newfoundland and Labrador and Nova Scotia.
Summer 2017: Geneviève participated in the 2017 field campaign with the Blue Team for 10 weeks as the team leader. She collected the water samples and the zooplankton samples, and did the filtrations in the lab.
