TL;DR: In this paper, a range of diagnostic criteria are required to help identify palaeotsunami deposits, including the chemical composition of interstitial water in coastal ponds and sedimentary sequences in coastal marshes and lagoons.

TL;DR: In this paper, the size, position, and long axis orientation of 626 boulders at Ibaruma and Shiraho Reefs at Ishigaki Island, Japan were investigated to elucidate the sedimentary differences of boulders deposited by tsunamis and storm waves in one area.

TL;DR: In this article, the authors investigated the size, shape, position, pre-transport setting and long-axis orientation of 175 boulders found along the south-eastern Ionian coast of Sicily.

TL;DR: For example, the work in this article shows that a significant part of the Hikurangi Margin has been active with locally intense methane seepage at present and in the past, with the widespread occurrence of dead seep faunas and knoll-forming carbonate precipitations offshore and on the adjacent land.

TL;DR: In this article, high-resolution seismic profiling and coring during 2006 and 2007 cruises revealed a low gradient, subaqueous delta system, up to 20m thick, surrounding the modern Mekong River Delta (MRD) in the west of the South China Sea.

TL;DR: In this article, rare earth elements (REE) were used to investigate provenance changes in sediments from Core DGKS9604, taken from the middle Okinawa Trough, and discrimination plots based on REE fractionation parameters suggest that the cored sediments have variable provenances over the last 30 ka, with the lower part (ca. 31-8.2 ka) ultimately originating mostly from the Changjiang (Yangtze River) and the upper part (7.1-0 ka) primarily from Taiwan.

TL;DR: In this article, the authors used a multi-parameter Bayesian network to investigate correlations between key variables that control and influence variations in cliff retreat processes, with the correct outcomes forecast in 70-90% of the modeled transects.

TL;DR: In this paper, a wave erosional model and a eustatic record of glacially induced oscillations of sea level, which modulated the elevation at which the waves operated through time, was used to determine the contribution of mechanical wave erosion to shelf development.

TL;DR: In this paper, the authors present seismic data across the Porangahau Ridge on the outer accretionary wedge and show high-amplitude reflections above the regional BSR level.

TL;DR: In this article, the authors used trace element and rare earth element (REE) concentrations in cold seep carbonates from the northern continental slope of the South China Sea to indicate source fluid characteristics and redox conditions.

TL;DR: In this article, three sediment cores between 60 and 71 m in length, obtained from localities on the seismic profile lines, were analyzed for sedimentary characteristics, clay mineral components, and benthic foraminiferal and ostracod assemblages and were also dated by AMS 14 C and optically stimulated luminescence.

TL;DR: The Poverty Indentation as mentioned in this paper is a seamount impact on the seafloor of the Waipaoa catchment that is attributed to multiple seamount impacts over the last c. 1-Myr period, accompanied by canyon incision, thrust fault propagation into the trench fill, and numerous large-scale gravitational collapse structures with multiple debris flow and avalanche deposits ranging in downslope length from a few hundred metres to more than 40 km.

TL;DR: In this article, a bottom-towed electric dipole-dipole system was used to reveal the occurrence of gas hydrate and methane related to the seeps in the Wairarapa region of New Zealand.

TL;DR: In this paper, pyritiferous nodules, crusts and slabs, tubes, and filled molds were recovered from the Kouilou pockmarks on the Congo deep-sea fan in approximately 3100m water depth.

TL;DR: The Le Danois Contourite Depositional System (CDS) as mentioned in this paper is unique with respect to the known sedimentary systems along the upper slope of the Biscay margin and has a strong potential to contain a record of the Neogene palaeoceanography.

TL;DR: In this paper, the authors present recently acquired high-resolution seismic data and older lower resolution seismic data from Rock Garden, a shallow marine gas hydrate province on New Zealand's Hikurangi Margin, revealing plumbing systems that supply gas to three general sites where seeps have been observed on the Rock Garden seafloor.

TL;DR: In this article, the authors examine the evolution of barrier islands in terms of their morphology and the transition from a regressive barrier island to a transgressive barrier island, which is referred to as a threshold-driven barrier island transition.

TL;DR: In this article, the impact of sea level and East Asian monsoon rainfall intensity on erosion and weathering during the last 25,000 years was investigated along core MD01-2393 recovered off the Mekong River mouth.

TL;DR: In this article, a 3-dimensional morphological response of a cliff face to two typical storm types was carried out by analysing the impact of 27 storms that occurred from April 2007 to April 2009.

TL;DR: In this paper, the authors show new high-resolution records of clay minerals, grain size and mass accumulation rate (MAR) of terrigenous materials from Ocean Drilling Program (ODP) Site 1144, together with trace element concentrations in siliciclastic sediments from ODP Site 1146.

TL;DR: The North-West Borneo Trough has been interpreted as an accretionary prism that has been preserved in place when subduction ceased in the Middle Miocene as discussed by the authors.

TL;DR: In this article, multibeam bathymetry and backscatter data collected as part of the Irish National Seabed Survey and Integrated Mapping for the Sustainable Development of Ireland's Marine Resource programmes is used to investigate the glacial geomorphology of the Malin Shelf.

TL;DR: In this article, the authors presented detailed measurements of hydrodynamic variables obtained over complete spring and neap tidal cycles in a multiple-inlet system in Southern Portugal (Ria Formosa) and showed that two main interconnected inlets servicing an embayment can coexist, at least over a time scale of several decades.

TL;DR: In this paper, the authors used towed cameras and direct sampling gear to explore cold seep communities along the New Zealand Hikurangi margin and found that the dominant, symbiont-bearing taxa include siboglinid worms, vesicomyid clams and bathymodiolin mussels.

TL;DR: In this article, the authors combined geochronological framework, isotope geochemical signatures and structural observations of methane related authigenic carbonate settings and associated cold-water corals from offshore New Zealand.

TL;DR: In this paper, the authors studied emplacement dynamics of the December 26, 2004 tsunami deposits in artificial shallow ponds and in shallow lagoons, along the northern coast of Sumatra in Banda Aceh area.
