TL;DR: Autonomous Underwater Vehicles (AUVs) have a wide range of applications in marine geoscience, and are increasingly being used in the scientific, military, commercial, and policy sectors as mentioned in this paper.

684 citations


Journal ArticleDOI
TL;DR: The contourite paradigm was conceived a few decades ago, yet there remains a need to establish a sound connection between contourites, basin evolution and oceanographic processes.

600 citations


Journal ArticleDOI
TL;DR: In this paper, a unifying stratigraphic framework of the Messinian Salinity Crisis (MSC) events has been constructed, derived mainly from onshore data and observations, but incorporating different perspectives for the offshore and provides hypotheses that can be tested by drilling the deep Mediterranean basins.

449 citations


Journal ArticleDOI
TL;DR: The first digital seafloor geomorphic features map (GSFM) of the global ocean has been presented in this paper, which includes 131,192 separate polygons in 29 geomorphic feature categories, used here to assess differences between passive and active continental margins.

389 citations


Journal ArticleDOI
TL;DR: In this article, an analysis of seismic and geodetic data, together with recorded tsunami waveforms, was performed to infer the location of the most likely additional source of the 2011 Tohoku tsunami from a submarine mass failure (SMF).

224 citations


Journal ArticleDOI
TL;DR: In this article, the authors proposed that thin and fine deposits are typical of flows triggered by hyperpycnal river floods, rather than thicker sand layers with traction structure or displaying inverse-to-normal grading.

221 citations


Journal ArticleDOI
TL;DR: A general review of the sub-seafloor biosphere is presented in this article, which includes an update and assessment of prokaryotic cell distributions within marine sediments.

219 citations


Journal ArticleDOI
TL;DR: In this paper, the authors examined the present knowledge of Holocene continental shelf deposits in relation to the processes for their formation, from the prospective of marine sediment dynamics, and developed a modeling approach to the formation of sedimentary records.

172 citations


Journal ArticleDOI
TL;DR: In this paper, the authors used a marine oxygen isotope (MIS) substage 5e (mIS 5e) to infer the depth of coral reef terraces during the last interglacial.

154 citations


Journal ArticleDOI
TL;DR: In this paper, multi-channel seismic reflection data, well logs, and recovered sediment cores have been used to characterize the geologic controls on the occurrence of gas hydrate in the Shenhu area of the South China Sea.

137 citations


Journal ArticleDOI
TL;DR: In this paper, the authors define four storm-impact regimes and include erosive as well as accretionary responses, and map out the changes in barrier geometry (elevation and width) over various time scales, from weeks to years or even longer, under varying forcing conditions, including changes in storminess and sea-level rise.

Journal ArticleDOI
TL;DR: In this paper, the impact of storm clusters with closely spaced individual storms reaching the beach is investigated by combining historic measurements of beach profile surveys and numerical modelling of storm induced beach change.


Journal ArticleDOI
TL;DR: In this article, ICP-OES analyses of bulk nodules from the Clarion and Clipperton Zone (CCZ) of the equatorial eastern Pacific have been analyzed to determine their chemical and mineralogical compositions.

Journal ArticleDOI
TL;DR: In this article, the authors present the current practice of investigations of seafloor instabilities and deformation processes, based on extensive research conducted over the last years, which sets the scene for future research activities in this field.

Journal ArticleDOI
TL;DR: In this paper, high-resolution stratigraphic calibration of Sr isotope data indicates that only a very thin unit (commonly < 50m) in the uppermost part of the “seismic” Upper Evaporites is characterized by the typically lower values for Sr isotopes with respect to the global Ocean which characterize stage 3 onshore successions (Lago Mare event).

Journal ArticleDOI
TL;DR: In this paper, the authors focus on the tectonic, sedimentary, and volcanic evolution of a unique back-arc basin (Ulleung Basin) in the southwestern part of the East Sea (Sea of Japan).

Journal ArticleDOI
TL;DR: In this paper, the authors applied two behavior-oriented equilibrium shoreline models that relate the rate of cross-shore shoreline displacement to the wave energy and wave energy disequilibrium.

Journal ArticleDOI
TL;DR: In this paper, the results from nearly three decades of marine geological research in the northwestern Gulf of Mexico are compiled in an effort to understand those factors (e.g., sea-level rise, sediment supply, subsidence, antecedent topography) that influenced coastal evolution during the last eustatic cycle.

Journal ArticleDOI
TL;DR: In this paper, the authors compare the similarities and differences between the Axial and Endeavour volcanic systems and identify reasons why they are ideal candidates for comparative studies, and present a comparison of the two systems.

Journal ArticleDOI
TL;DR: A forward and inverse numerical model for tsunami sediment transport has been developed over the last two decades as discussed by the authors, which is capable of delineating the time evolution of tsunami hydrodynamics, sediment transport and the resulting morphological changes associated with erosion and deposition.

Journal ArticleDOI
TL;DR: In this article, the authors used seismic data to understand the evolution of isolated carbonate platforms on the continental slope of the northern South China Sea (Xisha Uplift) in the early Miocene and have remained active up to the present.

Journal ArticleDOI
TL;DR: In this article, the response of surface sediments to tsunami is not yet fully understood, although it is accepted that large tsunami waves impact the sea floor, the response is not fully understood.

Journal ArticleDOI
TL;DR: In this article, a review of Quaternary Milankovitch cycles as recorded on modern continental shelves worldwide is presented, focusing on selected case studies from Mediterranean (Adriatic and Tyrrhenian seas) and Atlantic (gulfs of Mexico and Cadiz) margins.

Journal ArticleDOI
TL;DR: In this article, the authors present an assessment of tsunami hazard along the U.S. Atlantic margin and conclude that most of the landslides are translational, were probably initiated by seismic acceleration, and failed as aggregate slope failures.

Journal ArticleDOI
TL;DR: In this article, the Pearl River has formed a distal, shore-parallel Holocene mud deposit on the northwestern continental shelf of the South China Sea; investigations into its spatial distribution and evolutionary history are necessary for an improved understanding of such sedimentary systems.

Journal ArticleDOI
TL;DR: In this paper, numerical modeling of sediment transport on the Sendai Plain in northeast Japan, caused by the 2011 Tohoku-oki tsunami, was performed to investigate why onshore tsunami deposits included small amounts of marine materials and to explain the gap between the maximum inland extent of the recognizable sand layer and the limit of inundation.

Journal ArticleDOI
TL;DR: In this paper, the formation and formation mechanism of the mud deposit in the central South Yellow Sea of China during the last 40kyr are studied based on the analysis of particle size, sediment density, chemical features, magnetic properties and AMS 14 C ages of a new core YS01A together with other available core data.

Journal ArticleDOI
TL;DR: In this paper, the authors inferred the presence of a seamount-related deep-water contourite depositional system, located on the northwestern margin of the Northwest Sub-Basin of the South China Sea.

Journal ArticleDOI
TL;DR: In this article, a statistical relation was found between the flow depth and sediment thickness, defined as the sediment thickness divided by the maximum flow depth at each survey site, fits well with the logarithmic normal distribution with geometric average of about 2%.
