Picophytoplankton Population Dynamics from Fixed and Underway Observations of Cell Traits
Autonomous flow cytometry at the Martha's Vineyard Coastal Observatory has allowed for nearly continuous observation of picophytoplankton cells since 2003. These high-resolution measurements can inform population models to quantify the vital rates for two different groups of picophytoplankton. I will compare the dynamics of these two groups and relate those to local environmental variables. To evaluate whether the insights gained from the observatory are relevant more broadly, I have analyzed flow cytometry measurements made from the underway system of 17 research cruises on the Northeast U.S. Shelf between 2018 and 2021. Critical aspects of the relationships between temperature, light, abundance and division rate are consistent across taxa and across the shelf. These findings bolster our confidence in the inferences we can draw from both fixed and underway flow cytometry, and provide a more detailed picture of the functional diversity and cross-shelf variability in picophytoplankton communities.
