Investigating the geodynamics of the Indian plate using time-dependent mantle convection models
The northward migration of the Indian plate after breaking apart from Pangaea in Mesozoic followed by its collision with Eurasia during Cenozoic is a remarkable example of continental drift. Associated with this tectonic ... -
An investigation of the role of buoyancy in magnetic polarity transitions in rapidly rotating dynamos
The dynamo operating within the Earth’s outer core generates a predominantly north-south dipolar magnetic field. Occasionally, the magnetic dipole axis flips its orientation and retains its approximate alignment with the ... -
The keeper of Chronicles - Investigating calcium carbonate archives using clumped thermometry
Calcium carbonates (CaCO3) are the most abundant mineral archive for reconstructing past climate owing to their tendency to register the environmental condition during their formation. From biogenically mediated carbonates ... -
Modulation of Metal Fluxes and their Isotope Ratios in the Ganga (Hooghly) Estuary
This thesis aims at constraining the impact of estuarine processes on the net riverine fluxes of select metals and their isotopic composition to seawater. I studied the Ganga (Hooghly) River estuary, a monsoon-dominated ...
