Outline of Final Research Achievements

We developed a novel method to know the shell density of calcareous zooplankton (foraminiera) by using Micro X-ray Computing Tomography (MXCT) successfully. We found that shell density of individual planktic foraminifers which were recovered by the sediment trap deployed at Stn. K2 (47N, 160E), North Pacific had remarkably changed seasonally. In particular, shell degradation progressed in winter season from December to April. According to observations of seawater chemistry, shell density changes might be closely associated with carbonate systems and related physicochemical parameters: vertical mixing, pH, TCO2 and Omega. Geochemical proxy (strontium-calcium ratio, Sr/Ca) of individual foraminiferal shell indicated strong correlation with shell density, and it suggests that Sr/Ca of foraminiferal shells has potential to be a quantitative tracer of carbonate dissolution. These result should contribute to understand material cycles of ocean and biogeochemical cycles.
