The Global Evaluation of the Impacts of Storms on freshwater Habitat and Structure of phytoplankton Assemblages (GEISHA) project is using long-term monitoring datasets and high-frequency data available through international networks to address questions about the impacts of storms on phytoplankton community in over 40 lakes across the globe. GEISHA has been developed within the context of the Global Lake Ecological Observatory Network (GLEON) initiative called “Storm-blitz”. “Storm-blitz” assembles an international group of investigators interested in contributing to theoretical discussions and sharing data to answer questions about the impacts of extreme events on phytoplankton communities. Although climate change is expected to cause more intense and frequent extreme weather events, we only have a basic understanding of how these events might alter freshwater phytoplankton communities. The storm-blitz group was created in 2016 and gathers 17 researchers with diverse skillsets and experiences to focus on data compilation and analysis (https://www.geisha-stormblitz.fr/).
The objective of GEISHA is to address questions about the impacts of storms on phytoplankton community through sharing of long-term datasets and high-frequency data in more than 40 lakes in Europe, the Middle East, East Asia, South America, and North America. The goals of GEISHA are to 1) create the time, space, and resources to work as a cohesive unit, 2) gather and standardize long-term datasets, 3) perform meta-analyses to evaluate the sensitivity of aquatic ecosystems to extreme weather events, and 4) provide new frameworks to explore theoretical and applied questions related to phytoplankton species diversity and succession in aquatic ecosystems.
