TL;DR: A carbonate accumulation record that covers the past 53 million years from a depth transect in the equatorial Pacific Ocean is presented and large superimposed fluctuations in carbonate compensation depth are found during the middle and late Eocene.
Journal ArticleDOI
Inversion of multicomponent, multiazimuth, walkaway VSP data for the stiffness tensor
Pawan Dewangan,Vladimir Grechka +1 more
TL;DR: In this paper, Horne and Leaney proved the feasibility of joint inversion of the slowness and polarization vectors for parameters of transversely isotropic media with a vertical symmetry axis (VTI symmetry).
Journal ArticleDOI
Physical modeling and analysis of P-wave attenuation anisotropy in transversely isotropic media
TL;DR: In this article, the spectral-ratio method was used to estimate the group effective attenuation coefficient of P-waves transmitted through the sample for a wide range of propagation angles from 0° to 90° with the symmetry axis.
Journal ArticleDOI

TL;DR: In this article, the authors reported evidence of paleo-cold seep associated activities, preserved in methane-derived carbonates in association with chemosynthetic clams (Calyptogena sp) from a sediment core in the Krishna-Godavari basin, Bay of Bengal.

TL;DR: The Pacific Equatorial Age Transect (PEAT) as discussed by the authors was designed to recover a continuous Cenozoic record of the equatorial Pacific by coring above the paleoposition of the Equator at successive crustal ages on the Pacific plate.
