Description
Oceanographers can now collect flow cytometry data in real time while onboard a moving ship, which provides them with fine-scale information about the distribution of phytoplankton across thousands of kilometers. This presents an exciting opportunity to learn new insights about the microbial ecology of the ocean. We present a set of novel statistical models to estimate the time-varying phytoplankton subpopulations while simultaneously identifying the specific environmental drivers. We apply this model to data from numerous oceanographic ships deployed to the North Pacific ocean, and learn new insights about the relationship between microbial populations in the ocean and environmental factors.
