Paleoceanography and Paleoclimatology Group (PPG)

RESEARCH OBJECTIVES
  • Understanding the sedimentary organic matter (SOM) dynamics in the marine marginal seas of the Western & North Pacific and Indian Ocean using C and N isotopes mixing models and bromine to organic carbon ratio
  • Deciphering the dominant control of SOM in these environments in terms of glacial-interglacial climates for the last ~50 ka
  • Establishing high-resolution marine 15N records for the past ~50 ka from the Arabian Sea
  • Reconstructing the Holocene Asian monsoon and environmental changes from lake and marine sedimentary archives
  • Investigating Earth’s critical zone processes in East Asia to understand tropical-subtropical weathering-climate link on modern as well as glacial-interglacial timescales
