The devastating earthquake (and the corresponding tsunami) that struck the Indian Ocean
near Sumatra (Indonesia) on 26 December, 2004 was extremely powerful. In the present
study, a very high resolu...
The Contributions of Abyssal Hill Morphology and Noise to Altimetric Gravity Fabric
Noise Altimetric Gravity Fabric

2015/7/29
Earth's deep seafloor is, for the most part, a vast, unexplored terrain. Only a miniscule fraction has ever been observed directly, using deep submersibles and remotely operated vehicles. Most of our ...
On Improved Gravity Modeling Supporting Direct Georeferencing of Multisensor Systems
GPS/INS navigation calibration
font style='font-size:12px;'>
2015/7/15
Typically, inertial navigation systems assume the gravity field to be normal (ellipsoidal), meaning that the deflections of the vertical
(DOV) are ignored in the gravity compensation procedure. This ...
