Outline Activities
My research interests are marine biogeochemical cycles, carbonate production of coral reefs, evolution of coral-algal symbiosis, and their connections to global environmental changes through the geological timescale. My approach is reconstruction of environmental and metabolic records in modern and fossil coral skeletons.
Research Interests
  • Calcification and geochemical signals in coral skeletons under the hydrothermal and high pCO2 environment
    keyword : coral skeletons, hydrothermal vent, high pCO2, geochemical proxy, calcification
  • Reconstruction of Kuroshio transport and migration in a global warming trend
    keyword : Coral skeleton, Kuroshio, transport, migration, global warming
  • Variation of climate and carbonate production of coral reefs through Holocene
    keyword : Coral reef, Holocene, climate change, carbonate production
  • Variation in marine nitrogen budgets during the last 200-year global warming
    keyword : coral skeletons、nitrogen isotopes, nitrogen budget, global warming
