Kilo Nalu

In collaboration with University of Hawaii Oceanographers Eric Heinen De Carlo, Fred Mackenzie, and Christopher Sabine, PMEL maintained a moored buoy array around Oahu, Hawaii. Two moorings on the South Shore, Ala Wai and Kilo Nalu are part of the PacIOOS water quality monitoring program. Other moorings, CRIMP2 and Kaneohe Bay, are located in Kaneohe Bay. 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.
