Global Evaluation of the Impacts of Storms on freshwater Habitat and structure of phytoplankton Assemblages
Phytoplankton abundance and composition are sensitive to water column conditions which are strongly influenced by weather (e.g., wind and rain) and climate change.
GEISHA was framed in support to the GLEON Stormblitz project to gather and analyse time-series through collaborative efforts to assess the impacts of storms on phytoplankton. The project includes more than 80 researchers from governmental institutes and universities.
GEISHA’s goals were to:
- gather and standardize existing long-term datasets,
- assess the impact of storms on nutrients, light, water column stability and subsequent impacts on the structure of phytoplankton communities,
- perform meta-analyses to evaluate the sensitivity of aquatic ecosystems to extreme weather events, and
- provide new frameworks to explore theoretical questions related to phytoplankton diversity, succession and ecosystem resilience to extreme weather events.

GEISHA received funding from the USGS John Wesley Powell Center for Synthesis and Analysis, the University of Savoie Mont-Blanc (France), Fulbright, and the French embassy in Canada (grant Mourou/Strickland).
GEISHA brings together specialists in limnology, plankton ecology and taxonomy, global change, statistics and data analysis.
