The Investigation of Shallow Structures at the Meishan Fault Zone with Ambient Noise Tomography Using a Dense Array Data

open access: yesApplied Sciences, 2022
Seismic monitoring relies on seismography. However, the high cost of seismic equipment has presented a challenge to increasing the density of seismic networks in previous decades.

Very high resolution seismic profiling at the Brazil Margin [PDF]

open access: yesEos, Transactions American Geophysical Union, 2012
Acoustically stratified seismic images are widely used in studies of sedimentation mechanisms producing thick sedimentary aprons on continental rises. However, insuffcient vertical resolution of seismic records commonly restricts a more detailed interpretation of individual reflectors within accumulations to reconstruct specifc short‐term ...

High-resolution shear-wave seismic reflection as a tool to image near-surface subrosion structures – a case study in Bad Frankenhausen, Germany [PDF]

open access: yesSolid Earth, 2016
Subrosion is the subsurface leaching of soluble rocks that results in the formation of depression and collapse structures. This global phenomenon is a geohazard in urban areas.

High‐resolution common‐depth‐point seismic reflection profiling: Instrumentation [PDF]

open access: yesGEOPHYSICS, 1986
Seismic recording hardware must be a deliberately designed system to extract and record high‐resolution information faithfully. The single most critical element of this system is the detector. The detector chosen must be capable of faithfully generating the passband expected and furthermore, must be carefully coupled to the ground.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Buried volcanic structures in the Gulf of Naples (Southern Tyrrhenian Sea, Italy) resulting from high resolution magnetic survey and seismic profiling

open access: yesAnnals of Geophysics, 2005
In this paper we present a correlation between volcanic structures and magnetic anomalies in the Gulf of Naples (Southern Tyrrhenian Sea) based on high resolution magnetic profiling.

Study of blind thrust faults underlying Tokyo and Osaka urban areas using a combination of high-resolution seismic reflection profiling and continuous coring

open access: yesAnnals of Geophysics, 2003
We acquired high-resolution seismic reflection profiles and continuously cored boreholes to evaluate active flexures produced by major blind thrust fault systems within two densely populated Neogene-Quaternary sedimentary basins in Japan: the ...

SUGAR Site Gas Hydrates as a new energy source - Reconnaissance of a pilot location for the SUGAR project - Cruise No. MSM34, December 06, 2013 - January 16, 2014, Varna, Bulgaria - Varna, Bulgaria [PDF]

open access: yes, 2014
Cruise MSM34 of R/V MARIA S. MERIAN aimed to investigate a possible test site location for the German SUGAR project. The well sealed gas hydrate deposit should be accessible by the mobile drilling device MeBo 200. During the two legs of cruise MSM34 of R/

Sea Beam Survey of an Active Strike-Slip Fault: The San Clemente Fault in the California Continental Borderland [PDF]

open access: yes, 1989
The San Clemente fault, located in the California Continental Borderland, is an active, northwest trending, right-lateral, wrench fault. Sea Beam data are used to map the major tectonic landforms associated with active submarine faulting in detail ...

Current-eddy interaction in the Agulhas Return Current region from the seismic oceanography perspective [PDF]

open access: yes, 2013
Interleaving in the Agulhas Return Current (ARC) frontal region is commonly manifested in the form of thermohaline intrusions, as sub-tropical and sub-polar water masses of similar density meet.
