Climate Change Impact on Marine Diversity: Phytoplankton adaptation to resource variability

Project description

Mapping phytoplankton diversity in changing oceans

Climate change is rapidly altering ocean environments, threatening phytoplankton diversity – the foundation of vital marine ecosystems. These microscopic organisms face increasing pressure from shifting resource availability and extreme climate events, yet the links between these changes remain poorly understood. Supported by the Marie Skłodowska-Curie Actions programme, the CliMaDiv project aims to bridge this knowledge gap by investigating how climate-driven variability impacts phytoplankton communities. By integrating global ocean modelling, NASA satellite observations and specialised observatory data, the project will map global phytoplankton strategies to reveal the mechanistic links between environmental variability and biodiversity. Ultimately, CliMaDiv will launch an Outlook platform to translate results for policymakers and the public, fostering informed decision-making and raising societal awareness.

Objective

Climate change is reshaping the ocean environment for phytoplankton by altering resource availability through intensified stratification and increased climatic variability and extremes. These changes threaten phytoplankton diversity, which plays a vital role in sustaining ecosystem functions and services. However, the links between climate-driven environmental changes and phytoplankton diversity remain poorly understood. CliMaDiv will generate critical new knowledge by linking resource variability patterns with temporal strategies of phytoplankton and assessing how phytoplankton communities are impacted by climate change. Using the ECCO-Darwin global ocean modeling framework, NASA’s PACE hyperspectral observations, and the uniquely rich time series of the HCMR Poseidon observatory, CliMaDiv will pursue three research objectives: (RO1) assess the impacts of climate-change-induced resource variability on marine phytoplankton diversity (1992–present); (RO2) map the global biogeography of phytoplankton temporal strategies and ecosystem responses; and (RO3) integrate modeling and in-situ observations to elucidate the mechanistic links between resource variability and biodiversity of phytoplankton. To maximize impact beyond the scientific community, the CliMaDiv Outlook platform will communicate results to European policy and research programs, stakeholders, and the public, supporting informed decision-making and broader societal awareness.
