Major achievements
Dr. Hodaka Kawahata has significantly contributed to research on the carbon cycle and biogeochemical processes in the Earth’s surface environment, advancing studies on past, present, and future environmental changes. Through sediment trap observations, analyses of corals and freshwater systems, and precise culture experiments on biomineralization, he has gained a deep understanding of the factors governing environmental variability and developed high-precision methods for extracting past environment information. By applying these techniques to seafloor sediments and corals, he has conducted high-resolution studies in paleoclimatology and paleoceanography, as well as research on the response of calcifying organisms to ocean acidification driven by human activities. Furthermore, Dr. Kawahata has expanded interdisciplinary research beyond the natural sciences, integrating insights from humanities and social sciences to explore human migration and societal evolution. In addition to his research achievements, he has played a vital role in mentoring numerous researchers. Furthermore, he has made significant contributions to the establishment and promotion of the journal Progress in Earth and Planetary Science (PEPS), enhancing the international dissemination of academic research from Japan.
