Comparisons between POC and zooplankton swimmer flux from sediment traps in the subarctic and subtropical North Pacific
Seasonal changes in zooplankton swimmer (ZS) abundance, biomass and community structure were evaluated based on samples collected by moored sediment traps at a depth of 200 m in the subarctic (SA) and subtropical (ST) western North Pacific. Based on these samples, we made comparisons on two topics:...
