High flux and stable isotope compositions (d13C and d15N) of sinking particulate organic matter in the Ulleung Basin as a biological hot spot in the East/Japan Sea

Abstract

The southwestern part of the East/Japan Sea, the Ulleung Basin, is one of the biological hot spot in terms of high primary production and f-ratio. To examine the relationship between phytoplankton productivity and biological pump efficiency, we performed a sediment trap experiment and stable carbon and nitrogen isotope analysis of sinking particulate organic matter (POM) in the Ulleung Basin, we performed a sediment trap experiment and stable carbon and nitrogen isotope analysis of sinking particulate organic matter (POM) in the Ulleung Basin
