Group Head
Dr. Sreeush M. G. has just completed his Ph.D. thesis on "Forward and Inverse Modeling of Indian Ocean Carbon Cycle". He has joined as a Postdoctoral Fellow at IBS, Busan, South Korea as of Oct-2020.
His primary research theme was to use forward and inverse modeling techniques to optimize the 'Depth of Net Community Production' to be used in Biogeochemical Models.
In the Forward Modeling part, he utilized the OTTM with OCMIP-II Biogeochemistry. He showed that the community compensation depth (commonly known as compensation depth) in the OCMIP-II has a strong Spatio-temporal dependency.
Based on the compensation Irradiance, a radiance at which the net primary production in the upper ocean balances the respiration, he has redefined the definition of 'Compensation Depths' in OCMIP-II models.
The hypothesis is further tested with Inverse modeling methods using Bayesian Statistics in the OTTM model. Both forward and inverse modeling suggest that the Indian ocean community compensation depth has both spatial and temporal variability over the seasons.
The improved estimates of new parameterization to compensation depth has improved the seasonal cycle of simulated pCO2 and pH in the OTTM.
He also has published papers on Indian Ocean acidification and found that the western Arabian Sea is Acidifying faster, and acidification is exacerbated due to SST warming, additionally by 16%.
In his thesis, he has used the Bayesian inversion and Incremental Optimization techniques to propose new arrays for pCO2 observations in the Indian Ocean.
He has published five papers to his credit.
