Journal ArticleDOI
Bottom-simulating reflectors: Seismic velocities and AVO effects
TL;DR: In this paper, the wave velocities of ice and gas hydrate-bearing sediments were obtained as a function of concentration and temperature. And the reflection coefficients were computed with a viscoelastic single-phase constitutive model.
Journal ArticleDOI
Sicily’s fold–thrust belt and slab roll-back: the SI.RI.PRO. seismic crustal transect
Raimondo Catalano,Vera Valenti,Cinzia Albanese,Flavio Accaino,Attilio Sulli,Umberta Tinivella,Maurizio Gasparo Morticelli,Claudio Zanolla,Michela Giustiniani +8 more
TL;DR: Sicily is a thick orogenic wedge formed by the foreland (African) and its Sicilian orogen and the thick-skinned, Calabrian-Peloritani wedge.
Journal ArticleDOI
Compressional velocity structure and Poisson's ratio in marine sediments with gas hydrate and free gas by inversion of reflected and refracted seismic data (South Shetland Islands, Antarctica)
Umberta Tinivella,F Accaino +1 more
TL;DR: In this paper, a bottom simulating reflector (BSR) was surveyed, within the Progetto Nazionale di Ricerche in Antartide (PNRA), and high resolution multichannel (MCS) reflection profiles were acquired, and a three-component Ocean Bottom Seismograph (OBS) was deployed where the BSR was particularly strong.
Journal Article
A method for estimating gas hydrate and free gas concentrations in marine sediments
TL;DR: In this article, a method for estimating gas hydrate and free gas concentrations versus depth in marine sediments, using Gassmann's equation, was proposed and tested against sonic log and VSP data.
Journal ArticleDOI
Marine Transform Faults and Fracture Zones: A Joint Perspective Integrating Seismicity, Fluid Flow and Life

TL;DR: Marine transform faults and associated fracture zones (MTFFZs) cover vast stretches of the ocean floor, where they play a key role in plate tectonics, accommodating the lateral movement of tectonic plates and allowing connections between ridges and trenches as discussed by the authors.
