| Research Abstract |
In order to maintain training dataset of diatoms for quantitative relative sea-level reconstructions, I studied contemporary diatom assemblages on inter tidal environments along Japanese coast. The study locations (401 stations), selected based on airphotos and topographic map to cover various sub-environments, such as salt marsh and tidal flat. The stations were leveled with reference to the nearest bench mark, and water conditions were also measured. Diatom specimens in each collected samples were identified and counted under light microscope. Results of canonical correspondence analysis using relative abundance based on counting data from Hokkaido and Kanto regions, diatom assemblage distribute relating elevation and salinity along coasts of the two regions.
