Two PacIOOS water quality buoys have been upgraded to include nutrient sensors. These new nutrient sensors, located at Kilo Nalu and near the Ala Wai outflow, will provide early warning of storm runoff or other poor water quality events in the popular beach areas near Waikiki.
In partnership with NOAA PMEL, the water quality buoys also measure carbon dioxide, temperature, salinity, chlorophyll, oxygen, and turbidity. View real-time data from the Ala Wai Buoy and the Kilo Nalu Buoy. Locations and archive data are available through the PacIOOS Map Viewer.
