mapco2_alawai Adrienne J. Sutton Christopher L. Sabine Eric H. De Carlo Pacific Islands Ocean Observing System (PacIOOS) 20080606 This buoy operated between June 5, 2008 and February 17, 2021 and was located approximately 300 m (1000 ft) offshore of Magic Island near the mouth of the Ala Wai Canal between Ala Moana Beach Park and Waikiki on the South Shore of Oahu in the State of Hawaii. It was moored in waters 7.5 m (25 ft) deep. Data were recorded every 3 hours and transmitted daily. This Moored Autonomous Partial Pressure of Carbon Dioxide (MAPCO2) buoy was primarily established to monitor ocean acidification, complementing a national array of moored carbon dioxide buoys across the Pacific, Atlantic, and Caribbean. Other important physical parameters were also monitored, including water temperature, salinity, turbidity, chlorophyll, and air pressure. Water quality measurements help provide early indications of potentially polluted run-off from storm drainage, sewage spills, and soil erosion from land-based waterways such as streams and other outflows that lead directly into the ocean. The buoy was primarily funded by NOAA's Ocean Acidification Program and supported by NOAA's Pacific Marine Environmental Laboratory (PMEL). The University of Hawaii at Manoa supported the maintenance of the buoy and instrumentation. Data are managed by 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. 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. 20080606T05:58:00Z 20210217T18:17:00Z Unknown -157.84800 -157.84800 21.27989 21.27989 -1.0 -1.0 Unknown http://pacioos.org/metadata/browse/mapco2_alawai.png Sample image.
