| Outline of Final Research Achievements |
In this study, we have analyzed microbial ecosystems in halal water and sediments from the Mariana Trench, Izu-Ogasawara Trench and Japan Trench, and discussed about the geological and oceanographical backgrounds that support the halal biosphere. In the Mariana Trench project, we have revealed that the microbial ecosystem in the halal water was distinct from those in the upper abyssal and bathyal waters. Moreover, we hypothesized that the trench ecosystem was supported by the intrinsic geochemical cycle especially for the suspension of organic compounds from slope sediment (Nunoura et al. PNAS 2015). We also obtained data that presented the presence of halal water biosphere in the other trenches such as Izu-Ogasawara and Japan Trenches.
