MAPCO2 Buoy: Maihi Bay, Hawaii Island, Hawaii


This buoy is located in Maihi Bay approximately 200 meters offshore of the west coast of Hawaii Island just south of Kahaluu-Keauhou in the State of Hawaii. It is moored in waters 15 m (50 ft) deep. Data are recorded every 3 hours and transmitted daily. This Moored Autonomous Partial Pressure of Carbon Dioxide (MAPCO2) buoy was primarily established to monitor ocean acidification within a tropical coral reef ecosystem in the Central Pacific, complementing a national array of moored carbon dioxide buoys across the Pacific, Atlantic, and Caribbean. Other important physical parameters are also monitored to help provide early indications of run-off from land-based waterways such as streams and other outflows that lead directly into the ocean. The buoy is funded as part of a gift from Dr. Priscilla Chan and Mark Zuckerberg to the Hawaii Institute of Marine Biology (HIMB) to improve Hawaii's ocean health. The University of Hawaii at Manoa supports the maintenance of the buoy and instrumentation. Data are managed by NOAA's Pacific Marine Environmental Laboratory (PMEL) at the NOAA Western Regional Center in Seattle, Washington. PMEL enables data streaming into the PacIOOS website for visualization purposes only: the near real-time data have not been post-calibrated or quality controlled and are therefore not of the climate quality that PMEL is required to achieve. Only post-calibrated and quality-controlled data should be used for scientific publications and are available for download separately at the NOAA Ocean Carbon Data System (OCADS) website in a delayed-mode capacity.

Purpose PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region. The mission of NOAA's Pacific Marine Environmental Laboratory (PMEL) Carbon Program is to advance scientific understanding of the ocean carbon cycle and how it is changing over time in support of NOAA's commitment to improve the Nation's ability to anticipate and respond to climate impacts and to conserve and manage healthy oceans, coastal ecosystems, and marine resources. This research includes documenting the evolving state of the ocean carbon chemistry with high quality measurements, studying the processes controlling the role of the ocean in the global carbon cycle, and investigating how rising atmospheric CO2 and climate change affect the chemistry of the oceans and its marine ecosystems.
