Large Amplitude Magnetic Anomalies in the Northern Sector of the Powell Basin, NE Antarctic Peninsula
Marine Geophysical Researches - Tập 19 Số 1 - Trang 65-80 - 1997
Magnetic profiles obtained during the Hesant 92/93 cruise with the R/V Hesperides show large amplitude anomalies (up to 1000 nT) along a 100 km wide band in the northern margin of the Powell Basin. The anomalies, which are also locally identified in the eastern and western margins, are attributed to the continuation of the two branches of the Antarctic Peninsula Pacific Margin Anomaly (PMA).

Drowned carbonate platforms in the Bismarck Sea, Papua New Guinea
Marine Geophysical Researches - Tập 30 - Trang 229-236 - 2010
Extinct volcanic islands in the Bismarck volcanic arc are fringed by well-developed coral reefs. Drowned platforms offshore from these islands provide evidence for subsidence in the central section of the arc, north of the Finisterre Terrane–Australia collision. Bathymetric and backscatter data collected onboard the R/V Kilo Moana in 2004 reveal regularly spaced (~200 m interval) drowned platforms...... hiện toàn bộ
A seismic refraction study of cretaceous oceanic lithosphere in the Northwest Pacific Basin
Marine Geophysical Researches - Tập 11 - Trang 239-261 - 1989
A seismic refraction study on old (≈110 Myr) lithosphere in the northwest Pacific Basin has placed constraints on crustal and uppermantle seismic structure of old oceanic lithosphere, and lithospheric aging processes. No significant lateral variation in structure other than azimuthally anisotropic mantle velocities was found, allowing the application of powerful amplitude modeling techniques.

The Bremen ocean bottom tiltmeter (OBT) – a technical article on a new instrument to monitor deep sea floor deformation and seismicity level
Marine Geophysical Researches - Tập 28 - Trang 13-26 - 2007
The Bremen ocean bottom tiltmeter is a new 6000 m-depth deep sea instrument for autonomous observation of sea floor tilt with signal periods longer than 7.5 s. The instrument also records vertical acceleration in the frequency range from DC to 1 Hz. The tiltmeter has an Applied Geomechanics Inc. 756 wide angle biaxial bubble tilt sensor with a resolution of 1.0μ rad (0.2 arc second). A Kistler Cor...... hiện toàn bộ
Variations in the thermal conductivities of surface sediments in the Nankai subduction zone off Tokai, central Japan
Marine Geophysical Researches - Tập 33 - Trang 269-283 - 2012
We investigated the relationship between variations in the thermal conductivity of surface sediments and the topography in the Nankai subduction zone off Tokai, central Japan, the easternmost part of the Nankai subduction zone, which has an accretionary prism with varied topography. We analyzed sediment thermal conductivity data obtained from the trough floor and accretionary prism. Variations in ...... hiện toàn bộ

Seismic and well logging interpretation for evaluation of the lower Bahariya reservoir, southwest Qarun (SWQ) Field, Gindi Basin, Egypt
Marine Geophysical Researches - Tập 38 - Trang 271-290 - 2017
This paper focuses on seismic and well log interpretations for evaluating the sandstones of the Cenomanian Bahariya Formation in the southwest Qarun Field, Gindi Basin, northern Western Desert of Egypt. The seismic profiles display a clear anticlinal structure intersected by reverse faults in the study area. This faulted anticline has been interpreted to be one of the Syrian arc system folds forme...... hiện toàn bộ
Ocean-bottom seismometer observations of seismic activity at Loihi Seamount, Hawaii
Marine Geophysical Researches - Tập 17 - Trang 485-501 - 1995
This study reports the result of deep ocean-bottom seismometer recording of an undersea volcanic event in progress. An array of five three-component, isolated sensor ocean-bottom seismometers (ISOBS) was deployed for 28 days on the summit and flanks of Loihi Seamount, Hawaii, to monitor seismicity. The deployment was prompted by reports from the Hawaiian Volcano Observatory (HVO) of a swarm of sma...... hiện toàn bộ
Mapping basin-wide subaquatic slope failure susceptibility as a tool to assess regional seismic and tsunami hazards
Marine Geophysical Researches - Tập 32 - Trang 331-347 - 2010
This study of subaquatic slope failures in Lake Lucerne, central Switzerland, presents a new concept for evaluating basin-wide slope stability through time as a potential tool for regional seismic and tsunami hazard assessments. Previously acquired high-resolution bathymetry and reflection seismic data, as well as sedimentological and in situ geotechnical data, provide a comprehensive data base to...... hiện toàn bộ
Morphology and tectonics of the Romanche Transform and its environs
Marine Geophysical Researches - Tập 16 - Trang 427-453 - 1994
We describe the results of GLORIA surveys of the Romanche Transform and neighbouring areas of the Equatorial Atlantic Ocean. These surveys have imaged the whole of the Romanche Transform Fault, the eastern end of the Saint Paul Transform, the spreading centre joining them, and the northern part of the spreading centre between Romanche and Chain transforms. They have also imaged representative part...... hiện toàn bộ
