Kāneʻohe Buoy

kaneohe_sm

The Kāneʻohe buoy is located in Kāneʻohe Bay, on the eastern side of the island of Oʻahu. The bay is semi-enclosed and consists of a variety of coral reefs, including patch reefs, fringing reefs, and a large barrier reef. Generally, ocean water moves over the barrier reef into the central bay area and returns flow in the northern and southern portions of the bay to the ocean. While the Kāneʻohe buoy is located in the outer, central bay region, the CRIMP2 buoy is located in the central southern part of the inner bay.

The Kāneʻohe buoy is managed by Dr. Christopher L. Sabine of the Department of Oceanography at the University of Hawaiʻi with near real-time data dissemination provided and managed by the NOAA PMEL Carbon Program.

The entire carbon dioxide (CO2) time series for the Kāneʻohe buoy is shown below. For closer inspection of the dataset, simply slide the striped black markers on the bottom right and left of the graph to narrow the time range. The CO2 for the air and sea water are in molar fractions (µmol/mol), meaning it is the molar amount that CO2 accounts for out of the total substance.
