On Feb. 17 CCE will set sail on the R.V. Revelle for a month-long research cruise investigating the processes driving long-term change in the California Current coastal upwelling biome.  Our team of scientists, students, and volunteers will focus on elucidating the impacts of multiple stressors on open-ocean ecosystems during marine heatwave disturbances.  We will also use cutting edge optical imaging approaches to investigate relationships between plankton taxa at high spatial resolution.  This research is built upon, and continues, long-term efforts to quantify the rates underlying long-term change in biogeochemical properties and marine populations in the CCE.
