Introduction to Hawaii Coastal MapCO2 buoys
PMEL’s CO2 Program, in collaboration with University of Hawaii Oceanographers Eric Heinen De Carlo and Fred Mackenzie , has installed a moored buoy array around Oahu, Hawaii. Two moorings on the South Shore are part of the HIOOS water quality monitoring program. Another mooring is located in Kaneohe Bay as part of the CRIMP program. Each mooring has mounted sensors which provide high resolution time-series measurements of the partial pressure of atmospheric boundary layer CO2 and surface water CO2 as well as surface water dissolved oxygen, temperature, and salinity. The University of Hawaii has mounted instruments on the moorings that measure sea surface chlorophyll a, turbidity, temperature, salinity, depth, pH, dissolved oxygen, and nitrate. These data are used to evaluate the temporal variability in air-sea CO2 fluxes and to assist in examining the mechanisms controlling CO2 fluxes.
