Research Abstract

Much attention has recently been paid to the dynamics of transparent exopolymer particles (TEP) in seawater, because TEP can play an important role in determining the capability of ocean carbon fixation as adhesives for aggregating marine organic matters. However, no such information has ever been available from the Oyashio region, NW Pacific where biological production is relatively high among the world’s oceans. In this study, we obtained crucial results of TEP production and its controlling factors during the spring bloom in Oyashio waters through field observations and laboratory experiments.
