Abstract

Chuuk Lagoon (Chuuk State, Federated States of Micronesia, Latitude 7.68°N - 7.38°N, Longitude 151.76°E -151.8°E), located in tropical western Pacific Ocean, is one of the largest semi-enclosed semi-triangular oceanic atoll lagoons in the world. It has a circumference of about 225 km-long protective barrier reef with about 61 km east-west and about 53 km north-south between the longest points. The Pacific Marine Environmental Laboratory (PMEL)/NOAA and the Korea-South Pacific Ocean Research Center (KSORC)/Korea Ocean Research and Development Institute (KORDI) established a long-term coral reef OA monitoring buoy (Chuuk K1) in Chuuk Lagoon in November 2011 as a collaborative project to monitor OA of this coral reef system. Currently, the parameters being transmitted eight times per day by the buoy are pCO2 in atmosphere and seawater, pH, seawater temperature, salinity and chlorophyll concentrations. These data are expected to contribute in the global effort to monitor and understand the current trend in OA along with other PMEL collaborating buoys in Australia, Hawaii and Caribbean waters as shown in PMEL homepage. We are also hoping to contribute in the regional effort to understand the effect of current high CO2 world on Chuuk and Pacific coral reef ecosystem. We are planning for the second buoy deployment in the future and continuing long-term ecosystem process study of the lagoon. Tin the world.
