My project focused on measuring the rates of oxygen production by different plants and phytoplankton in the estuary. I also calculated overall oxygen flux in the estuary using large time-series datasets collected from water quality monitoring stations. These measurements are important because they tell us about the health of an ecosystem and whether it stores or produces carbon.
