Current Projects
Global Mapping of the carbon cycle - project leader Prof. Dr. H. Kawahata
This project involves multidisciplinary work to monitor global climate change related parameters in oceans and on land. It includes study of satellite data from the viewpoint of primary productivity in the oceans, validation of the satellite data by studying chlorophyll concentration in the ocean surface waters, study of land vegetation cover, study of sinking matter flux in the oceans using sediment traps, study of deep sea cores to understand palaeoclimatic changes on the earth, study of coral reefs to understand their role in global carbon cycle, and also for obtaining a short record of recent climatic changes, because the oxygen isotopic data in the coral colonies is a good proxy of sea surface temperature change.
Study on Paleoceanography
- oceanographic environmental changes in the eastern equatorial Indian Ocean as inferred from amino acid and alkenone based biomarkersArchaen Park project
- about evolution of biomolecules and lifeBiomass project
