Determination of Ice Cover Parameters Using Seismoacoustic Noise
Abstract —A method for estimating ocean ice cover parameters (thickness, Young’s modulus, Poisson ratio, and density) that does not require the use of...

A hypothesis of the obliquely subducted Gagua Ridge below Nanao Basin based on uplifted structures in Ryukyu forearc
At the southernmost part of the Ryukyu subduction zone, six long-offset multi-channel seismic profiles were collected across three forearc basins and...

Crustal structure of the Gulf of Kachchh, northwest India
AbstractAnalyses of the marine geophysical data collected in four oceanographic cruises during 1974–2008 inside the Gulf of Kachchh, northwest India...

Broad fault zones enable deep fluid transport and limit earthquake magnitudes
Constraining the controlling factors of fault rupture is fundamentally important. Fluids influence earthquake locations and magnitudes, although the...

Analytic Acoustic–Elastic Coupled Equations and Their Application in Vector-Wave-Based Imaging of Ocean Bottom 4C Data
In conventional vector-wave-based elastic reverse-time migration, there are two types of artifacts: low-frequency artifacts and nonphysical...

Evidence of earthquake seasonality in the Azores Triple Junction
This work presents evidence of seasonal and inter-annual variations of the earthquake occurrence rate in the Azores Triple Junction, on the...

Gas migration signatures over the volcanic cratered seamount, off the Nicobar Islands in the Andaman Sea
The submarine volcanic arc off-Nicobar is seismologically very active with numerous earthquake swarms reported after the tsunamigenic 26th December...

Linear inversion-imaging method based on joint primary reflected waves and surface-related multiples
In marine seismic exploration, especially in deep-water and hard ocean-bottom cases, free-surface multiples are strongly developed. Compared with...

Crustal structure and variation along the southern part of the Kyushu-Palau Ridge
As an interoceanic arc, the Kyushu-Palau Ridge (KPR) is an exceptional place to study the subduction process and related magmatism through its...

Project Overview
The earth’s surface consists of continents and oceans. Continents cover nearly one-third of the earth’s surface and are essential to human survival....

Gas Hydrates in the Norwegian Sea
Gas hydrates are widespread in the Norwegian Sea, particularly near the site of a massive underwater mass wasting event called the Storegga Slide....

Moment magnitude (Mw) from hydrophone records of low energy volcanic quakes
Earthquake magnitude calibration using hydrophone records has been carried out at Campi Flegrei caldera, an active area close to the highly populated...

Hyperextended crustal structure of the Qiongdongnan Basin and subsequent magmatic influence from the Hainan mantle plume
The Qiongdongnan Basin (QDNB) is a rift basin located in the extension direction of the oceanic ridge of the Northwest Subbasin of the South China...

Gas Hydrates and Submarine Sediment Mass Failure: A Case Study from Sackville Spur, Offshore Newfoundland
Sackville Spur is a large, separated sediment drift deposit adjacent to Flemish Cap, offshore Newfoundland. It is a Neogene to Recent structure...

Hydrothermal flow and serpentinization in oceanic core complexes controlled by mafic intrusions
Deep-sea hydrothermal systems at slow/ultraslow-spreading mid-ocean ridges are often located within ultramafic rocks that are part of oceanic core...

Focal Parameters of Earthquakes Offshore Cape St. Vincent Using an Amphibious Network
Earthquakes with submarine foci are generally located with high uncertainties, and their focal mechanisms are poorly resolved, due to the confinement...

Crustal velocity structure of the Northwest Sub-basin of the South China Sea based on seismic data reprocessing
The deep crustal structure of the Northwest Sub-basin (NWSB) of the South China Sea (SCS) is of great importance for understanding the tectonic...

Oceanic crustal structure and tectonic origin of the southern Kyushu-Palau Ridge in the Philippine Sea
A new high-resolution velocity model of the southern Kyushu-Palau Ridge (KPR) was derived from an active-source wide-angle seismic...

Oceanic transform fault seismicity and slip mode influenced by seawater infiltration
Oceanic transform faults that offset mid-ocean ridges slip through earthquakes and aseismic creep. The mode of slip varies with depth and along...
