[MIS28-21] Microfocus X-ray Computing Tomography Technique: Applications for the Ocean Acidification study
Keywords:Microfocus X-ray CT, Planktic Foraminifera, Pteropod, North Pacific, Arctic Ocean, Ocean Acidification
Here we proposed a new method to evaluate shell density of marine calcifiers by using the Micro-focus X-ray Computing tomography (MXCT) technique. The MXCT has great potential to bring new information for morphometric analysis of biology by the innovating data acquisition. It can get precise transparent tomographic images of individual specimen with spatial resolution in submicron scales. At the same time, MXCT has become possible to achieve the information about shell density quantitatively. Shell density analysis of marine zooplankton measured by MXCT is most accurate and objective compared with any other existing methods (e.g. SEM observations and weight loss etc). This method is applicable to not only living species but also fossil species, therefore it might provide novel information about the OA ongoing in the modern ocean and occurred in the past. We will introduce about the MXCT technique and its latest results in application for our OA research in the North Pacific and the Arctic Ocean.
