Description
  • Abstract en My recent scientific interests have been to reconstruct palaeoclimates in the tropical and sub tropical areas using chemical tracer of biogenic carbonates including coral skeletons and molluscan shells, which have annual and daily growth bands. Understanding the past climate variability in the tropical ocean is a high priority in climate change research. The tropical climate variability has global consequences such as El Nino-Southern Oscillation (ENSO) and Asian-Australian monsoon but the instrumental records in this area are limited only up to past several decades. Recently coral skeletons have been widely used to understand the past climate variability in the tropical ocean. The oxygen isotopic and trace elemental records of living and fossil coral skeletons have provided the sea surface temperature and precipitation over several hundred years. Despite such a great advance, there still remain problems to use coral skeletons for reconstructing palaeoclimates because of complicated biological and physical processes during their formation. Here I would like to introduce recent my works concerned with these problems and solutions using biogenic carbonates in the skeletons of coral reefs dwellers.
