Structures of the oceanic lithosphere-asthenosphere boundary: Mineral-physics modeling and seismological signatures
[1] We explore possible models for the seismological signature of the oceanic lithosphere-asthenosphere boundary (LAB) using the latest mineral-physics observations. The key features that need to be explained by any viable model include (1) a sharp (<20 km width) and a large (5–10%) velocity drop, (2) LAB depth at ~70 km in the old oceanic upper mantle, and (3) an age-dependent LAB depth in the...
متن کاملEuler characteristics of oceanic sea states
We present an application of a novel Variational Wave Acquisition Stereo System (VWASS) for the estimation of the wave surface height of oceanic sea states. Specifically, we show that VWASS video technology combined with statistical techniques based on Euler Characteristics of random fields provides a new paradigm for the prediction of wave extremes expected over a given area of the ocean. © 20...
متن کاملEuler Characteristics and Maxima of Oceanic Sea States
We propose a novel Variational Wave Acquisition Stereo System (VWASS) that exploits new stereo reconstruction techniques for accurate estimates of the space-time dynamics of oceanic sea states. The rich information content of the acquired three-dimensional video data is exploited for predictions of directional spectra and large waves over an area by means of the Euler Characteristics of random ...

متن کاملPhysics of Neutron Star Crusts
The physics of neutron star crusts is vast, involving many different research fields, from nuclear and condensed matter physics to general relativity. This review summarizes the progress, which has been achieved over the last few years, in modeling neutron star crusts, both at the microscopic and macroscopic levels. The confrontation of these theoretical models with observations is also briefly...
