Abstract
As part of the Dokdo East Sea Time Series Studies (DETS) of the East Sea (Sea of Japan), a DETS buoy system equipped with a set of meteorological sensors 2 m above sea level, a conductivity-temperature-depth (CTD) sensor with a fluorescence detector was deployed on the 130-m-deep continental shelf of the Dokdo Islets. Chlorophyll a concentrations in surface water at the DETS buoy exhibited frequent low-concentration maxima in addition to low-frequency bimodal annual chlorophyll a concentration variations. These smaller frequent blooms appear to have been triggered by injection of nutrient-rich deep subsurface water to sunlit surface water. This eddy-pumping mechanism was hypothesized based on cross-correlation analyses among daily mean water temperature and salinity at various depths and wind speed, wave height, and in vivo chlorophyll a at the sea surface using a one-year data set retrieved from the DETS buoy.ence detector was deployed on the 130-m-deep continental shelf of the Dokdo Islets.
