Article
Seismic oceanography has the advantages of high resolution, fast acquisition and the availability large amounts of legacy data. Almost 20 years of studies of seismic oceanography allowed the following progress: 1) high-resolution imaging of various oceanic features such as mesoscale/sub-mesoscale eddies, internal waves/solitary waves, oceanic front...
Article
Previous studies of gas hydrate in the Dongsha area mainly focused on the deep-seated gas hydrates that have a high energy potential, but cared little about the shallow gas hydrates occurrences. Shallow gas hydrates have been confirmed by drill cores at three sites (GMGS2 08, GMGS2 09 and GMGS2 16) during the GMGS2 cruise, which occur as veins, blo...
Article
Studies of the most surficial sedimentary record from passive continental margins provide crucial knowledge about sedimentary dynamics and its changes through recent geological times. These studies allow understanding in detail the influence of both tectonic activity and long-term bottom-current circulation over the Late Quaternary sedimentary dyna...

O vulcão de lama serpentinizada Yinazao, localizado no antepaís das Marianas, foi amostrado durante a Expedição 366 do Programa IODP. Verificou-se a ocorrência de aragonite e calcite, predominantemente nos primeiros metros da coluna sedimentar, onde a oxidação e a circulação de água do mar mais se fazem sentir. Os resultados deste trabalho demonstr...

Ferruginous tubular structures concretions are widely distributed over the seafloor surrounding the Gran Burato depression in the Transitional Zone (TZ) province of the Galician Continental Margin (NW Iberian Margin). These bioforms-like structures are created by iron oxides precipitations into the tube-dwelling macrozoobenthos as a result of Fe2+...
Article
Submarine bubble plumes are associated with the fluid migration at hydrothermal systems, cold seeps, serpentinization processes, and areas of active tectonics. This work aims to investigate the potential of the seismic oceanography method for the detection and investigation of processes related to submarine bubble plumes formation. This is achieved...
Article
Large national programs in the United States and several Asian countries have defined and characterised their marine methane hydrate occurrences in some detail, but European hydrate occurrence has received less attention. The European Union-funded project “Marine gas hydrate – an indigenous resource of natural gas for Europe” (MIGRATE) aimed to det...

The aims of the present work are to understand the Yinazao features which provide authigenic carbonate precipitation and infer the major Carbon source in this system. We also propose a formation model of Yinazao authigenic carbonates by comparing them to authigenic carbonates from sedimentary mud volcanoes and pockmarks of the Gulf of Cadiz (GOC).

The Alpine orogeny is well recorded onshore and offshore by tectonic inversion of the Mesozoic rift basins. Large scale linear seamounts (more than 250 km long and with up to 5 km of uplift) involving oceanic and continental lithosphere were carried on top of thrusts, such as the Gorringe seamount and the Estremadura Spur in the SouthWest and West...

The West and SouthWest Margins of Iberia started their formation as intra-continental rifts during initial break up of Pangea in Triassic times. The tectono-stratigraphic record of the Algarve, Alentejo and Lusitanian basins and their offshore prolongation documents the syn-rift, post-rift and passive margin phases of the rifting process as well as...

Article
The Gulf of Cadiz is characterized by extensive active and inactive fluid escape structures which manifest as mud volcanoes, diapiric ridges, pockmarks and cold seeps. The high methane content and the presence of gas hydrates in the shallow sediments of the most active fluid escape structures indicate that these are areas of preferential migration...

Fluid escape structures including mega-pockmarks and mud volcanoes are found extensively in the N. Zhongjiannan Basin, S. China Sea. Individual pockmarks are circular, elliptical, crescent-shaped or elongated, with diameters ranging from 100s to 1000s meters and 10s or 100s meters in depth, forming groups or strings. Crescent pockmark (often formin...

The Galicia Interior Basin (GIB) is a ~3 km deep bathymetric trough located at the non-volcanic margin off West Iberia. It is considered as an aborted rift in the context of the opening of the North Atlantic rift system, one of the best studied non-volcanic margins. However, most of the works have focused on the Deep Galicia Margin and Iberian Abys...

The West Iberia continental margin is one of the best studied non-volcanic margins of the world, representing a classical end-member model. Nevertheless, to date most of the works have focused on the tectonic structure of the Deep Galicia Margin and Iberian Abyssal Plain segments, where final breakup occurred. However, complete knowledge involves t...

Article
The positioning of ocean bottom seismometers (OBS) is a key step in the processing flow of OBS data, especially in the case of self popup types of OBS instruments. The use of first arrivals from airgun shots, rather than relying on the acoustic transponders mounted in the OBS, is becoming a trend and generally leads to more accurate positioning due...

In harbors, siltation interrupts navigation and creates environmental problems that necessitate the expensive dredging of seaports. This paper proposes a simple and cost-effective method that uses Surfer 12 (Golden Software, Inc.) to estimate the distribution of sedimentary deposits at the bottom of a harbor. This method is based on a historical ap...

Subduction of a narrow slab of oceanic lithosphere beneath a tightly curved orogenic arc requires the presence of at least one lithospheric scale tear fault. While the Calabrian subduction beneath southern Italy is considered to be the type example of this geodynamic setting, the geometry, kinematics and surface expression of the associated lateral...

A field with more than 30 pockmarks was recently discovered in the Estremadura Spur outer shelf (Lourinhã Monocline). The processing of high-resolution seismic lines permitted the characterization of this pockmark field and of the seismic sequence of the Plio-Quaternary basin where they occur. Results show that this region has been affected by seve...

Ocean bottom seismometer positioning is a key step in the processing flow of OBS data, especially data acquired with self pop-up types of OBS instruments. Using first arrivals from airgun shots rather than acoustic transponders, not only saves time but also leads to more accurate positioning, due to the statistics from a large number of shots. The...

Research on ocean internal waves using seismic oceanography is a frontier issue both for marine geophysicists and physical oceanographers. Images of the ocean water layer obtained by conventional processing of multichannel seismic reflection data can show the overall patterns of internal waves. However, in order to extract more information from the...

The extents of volcanic island shelves result from surf erosion, which enlarges them, and volcanic progradation, which reduces them. However, mass-wasting, tectonics and sediment deposition also contribute to their morphology. In order to assess the relative significance of these various processes, we have mapped in detail Faial Island's shelf in t...

In this study, we analyzed stable calcium isotope results of authigenic carbonates from two cold seep areas of the Dongsha area and the Baiyun Sag in the northern South China Sea. The stable isotopes of carbon and oxygen as well as the mineral composition of authigenic carbonates were used to investigate control calcium isotope fractionation. The δ...
