Outline of Final Research Achievements

We have investigated the stable isotopic dispersions of individual benthic foraminifera to utilize them as new sea environmental proxy. The second aim of this study is to reutilize the archived sediment samples already taken from all over the world. As the results, we found that the stable carbon and oxygen isotopic compositions of Uvigerina akitaensis show the most reliable isotopic composition (low dispersion, close to isotopic equilibrium values) among several sampling sites. In addition, we found that Nonionellina labradorica, Bolivina spissa, Islandiella norcrossi, and Globocassidulina sp. also have reliable isotopic compositions. Besides, we found that we can utilize the isotopic dispersions of benthic foraminifera to evaluate the redeposition of sediment.
