This PhD utilizes ZooScan to analyze plankton community composition and abundance in the Belgian part of the North Sea, processing samples to study the impacts of marine heatwaves. By integrating these data with physical climate variables, we assess how heatwaves influence plankton phenology and dominance shifts. The data produced here, is sampled by continously through the underway system of the RV Simon Stevin, imaged by Plankton Imager (Pi-10), predicted by in-house models and followed by manual validation.

We first detect and characterize BPNS heatwaves using the Hobday method (≥5 days above the seasonal 90th-percentile SST), applying satellite SST data and validating against underway (~3 m) temperatures from the RV Simon Stevin as well as buoy data. The detected heatwaves events are compared based on intensity, duration, cumulative intensity, and timing across geographic and biologically defined regions. In parallel, we quantify phytoplankton and zooplankton composition, bloom timing, and abundance from the Belgian LifeWatch time series (zooplankton since 2014; phytoplankton since 2017) using ZooScan and Flowcam across nine coastal and eight offshore stations. By coupling physical extremes with community responses, this work advances mechanistic understanding and improves forecasting of plankton phenology and dominance shifts under a future of more frequent and intense marine heatwaves.
