Differentiating phytoplankton taxa in inland waters using in situ hyperspectral reflectance
data
by Loé Maire, EAWAG
Abstract: Phytoplankton play a central role in aquatic ecosystems, influencing biogeochemical cycles, food web dynamics, and overall water quality. Monitoring their composition is essential for assessing water ecosystem health and detecting environmental changes. This work investigates the potential of retrieving phytoplankton taxa composition from high-resolution in situ spectroscopy measurements by applying radiative transfer inversion and validating the results against phytoplankton abundance data obtained from an imaging microscope. This webinar will present the key findings of our research, demonstrating that remote sensing with radiative transfer inversions can track the evolution of phytoplankton blooms.
Biography: Loé Maire is a PhD candidate in the Remote Sensing Laboratories at the University of Zurich, as well as in the Remote Sensing group at Eawag (the Swiss Federal Institute of Aquatic Science and Technology). She holds a BSc and an MSc in Environmental Sciences and Engineering, specializing in water, soil, and ecosystem engineering from EPFL (École Polytechnique Fédérale de Lausanne), Switzerland. Her current research focuses on identifying phytoplankton taxonomic groups in eutrophic peri-alpine lakes using remote sensing technologies, combining ground- and satellite-based observations.
