| Research Abstract |
In order to develop a novel quantitative proxy for paleoceanography, we measured oxygen isotopes on silica in marine sediments. Our analytical system is able to measure the oxygen isotopes of small amount of silica(～ 50μg) within analytical errors of+-0.2‰. We measured oxygen isotopes of diatom frustules, radiolarian skeletons and quartz in marine sediments to collect basic data for paleoceanography.
