Wind-driven coastal upwelling is a well-described process responsible for the high productivity of Eastern Boundary Upwelling Systems such as the California Current. The physical and biological response to upwelling has been extensively described at mesoscale to regional scales, and several studies investigated the small-scale physical response including changes in water column structure and oceanic circulation. However, the corresponding submesoscale biological response, including phytoplankton, zooplankton, and their ecology, remains poorly known. Here we present results from a month-long experiment in Monterey Bay, California (June-July 2025), when a long-range autonomous underwater vehicle (LRAUV) surveyed the oceanic response to upwelling at 2-day resolution along a 40-km transect from the Año Nuevo upwelling center to the upwelling shadow inside the bay. The LRAUV carried fluorescence and bioluminescence sensors, used to describe broad planktonic groups such as diatoms, auto- and heterotrophic dinoflagellates, larvaceans, and zooplankton. We use this dataset, which covered an entire event from pre-upwelling conditions to strong upwelling to relaxation, to describe the physical and biological response to upwelling at km and daily timescales. The results provide insights on plankton dynamics and succession patterns in response to physical forcing at small spatial and temporal scales.
