The project involved conducting air-sea CO2 measurements in pre-selected bays on the island of Tutuila, American Samoa. Using a NOAA research vessel and a headspace equilibrator the student took CO2 samples from water columns in and around coral reef ecosystems and the air above these systems to calculate flux measurements. Using an YSI sonde the student took pH, salinity, and dissolved oxygen measurements. The student also assisted NOAA biologist Mareike Sudek in estimating coral reef health in these same bays.
