Abstract
Ocean is the largest mobile carbon inventory in the global carbon cycle and also absorbs about one third of anthropogenic carbon emitted to the atmosphere by human activities. Although continental margins and coastal areas cover only about7% of the world’s ocean surface area, they play a major role in oceanic carbon cycling. The complex and dynamic nature of these areas produce highly variable sea-air CO2 fluxes. Therefore, large ranges of error are involved in estimating the role of coastal carbon uptake in the global carbon cycle due to the complexity of coastal ecosystems and hydrodynamics. This study aims to understand the temporal variations of surface pCO2, its controlling processes and sea-air CO2 fluxes in the coastal area through time-series surface pCO2 data set from a pCO2 monitoring buoy during a year in the southern coastal water of Korea. Temperature and salinity of surface seawater, current profiles of water column and meteorological parameters have been measured in every minute by moored CTD (SBE 37) and ADCP (Workhorse Sentinel) under the buoy and meteorological sensors (RM-Young 86106, Airmar 200WX, and Vaisala PTB210), respectively. pCO2 in surface seawater andoverlying marine air have been measured by Battelle Seaology pCO2 Monitoring System in every 3 hours from July 2017. The seasonal variations of surface pCO2 were not significantly large, despite the large differences in SST.
