Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
Diachronous behavior of the Antarctic ice sheets: Weddell Sea, Antarctica
Inaccessibility due to harsh weather conditions and perennial sea ice has left the Weddell Sea embayment (WSE) vastly under-studied in comparison to other regions of Antarctica. Yet understanding its deglacial history since ...
Seismic imaging with traveltime and waveform inversion: Naga Thrust and Fold Belt, India
I demonstrate the utility of traveltime and waveform inversion in depth imaging of seismic data with the help of two 2-D multichannel seismic lines, Reg-07 and PO-03, shot perpendicular to the trend of the Naga Thrust and ...
Three-dimensional seismic structure of the Leeward Antilles arc from seismic refraction and refraction and reflection tomography
We have developed new velocity and Moho interface models for the Dutch Antilles region of the Leeward Antilles arc from independent and simultaneous 3-D inversion of first arrival and PmP traveltimes. The first arrival and ...
Glacial and climate history of the Firth of Tay, northeastern Antarctic peninsula
This study presents the Holocene deglacial and climate history from the Firth of Tay, Antarctic Peninsula derived from sediment cores and geophysical analysis. A robust chronostratigraphy is used to establish the timing ...
