Flow cytometric dissimilarity score from the summers 2020 and 2021: Independent Component Analysis (ICA) of FCM_b_ICC fingerprint embeddings, where each point represents a measurement. The points are arranged based on the distance between weights on independent components, with closer points indicating higher similarity. Data is shown for high-frequency sampling years 2020 and 2021. Points are color-coded to represent different events: Blues: 2020 data. Lighter shades correspond to specific event periods, while dark blue represents the baseflow. Reds: 2021 data. Darker shades correspond to specific event periods, while dark red represents the baseflow. X signify data points that were classified as dissimilar, while circles were similar to the reference period by the DS analyses. The base flow corresponds to the reference periods of the DS for each year, respectively.
