Abstract During opening of a new ocean, magma intrudes into the surrounding sedimentary basins. Heat provided by intrusions matures host rock, creating metamorphic aureoles potentially releasing large amounts hydrocarbons. These hydrocarbons may migrate to seafloor in hydrothermal vent complexes sufficient volumes trigger global warming, e.g., during Paleocene-Eocene Thermal Maximum (PETM). Mound structures at top buried observed seismic data off Norway were previously interpreted as...
Globally mud areas on continental shelves are conduits for the dispersal of fluvial-sourced sediment. We address fundamental issues in sediment dynamics focusing how is retained seabed shallow inner and what sources mud. Through a process-based comprehensive study that integrates dynamics, provenance, sedimentology, here we show key mechanism to keep water-column stratification forms dynamic barrier vertical restricts upward mixing suspended studied 1000 km-long belt extends from mouth...
Through a process called "bioturbation," burrowing macrofauna have altered the seafloor habitat and modified global carbon cycling since Cambrian. However, impact of on community structure microorganisms is poorly understood. Here, we show that microbial communities across bioturbated, but geochemically sedimentologically divergent, continental margin sites are highly similar differ clearly from those in nonbioturbated surface underlying subsurface sediments. Solid- solute-phase geochemical...
Long-term antibody responses to 23-valent pneumococcal polysaccharide vaccine (PPV) among HIV-infected patients receiving highly active antiretroviral therapy (HAART) are rarely investigated.Antibody three capsular polysaccharides [Pneumococcal (PPS) 14, 19F and 23F] were assessed 169 who received HAART PPV. Patients stratified into four groups according CD4 count at vaccination: group 1, CD4<100 cells/microL (n=35); 2, 100-199 (n=36); 3, 200-349 (n=34); 4, CD4>or=350 (n=64). The proportion...
Abstract In the past few years, large earthquakes and torrential rain hit southern Taiwan induced severe submarine hazards off SW coast. Marine sediments (turbidites) provide valuable records with which to study understand formation of these geo-hazards. The Pingtung Earthquake (two major events ( M L =7.0) plus many aftershocks), on 26 December 2006, triggered turbidity currents that severed cables in Fangliao Gaoping canyons. This caused significant economic loss. addition earthquake...
Abstract. Magmatic sill intrusions into organic-rich sediments cause the release of thermogenic CH4 and CO2. Pore fluids from Guaymas Basin (Gulf California), a sedimentary basin with recent magmatic activity, were investigated to constrain link between fluid seepage as well timing sill-induced hydrothermal activity. Sampling sites close vent field at northern rift axis cold seeps located up 30 km away rift. active showed slight imprint by indicated shallow circulation system transporting...
Sedimentary records of event deposits are crucial for regional natural disaster risk assessments and hazard history reconstructions. This study aims to identify deep-sea typhoon through immediate post-event sampling following super Haiyan (2013) Morakot (2009). After passed the South China Sea in 2013, five gravity cores were collected along path southern Basin (>3800 mbsl). The results showed that Super Typhoon with clear graded bedding preserved at top all cores. thickness layers ranges...
Three giant piston cores, MD18-3548 (20.08 m), MD18-3552 (45.98 and MD18-3547 (35.27 were collected from perched basins in offshore SW Taiwan, with the objective of studying event beds. Detailed grain-size analysis (1 cm resolution), 14C AMS dating, X-CT-scan above-mentioned cores performed, lithofacies carefully delineated. Four distinct identified, namely hemipelagic sediments, homogenites a silty basal layer, turbidites, thin layers. Homogenites documented for first time they considerably...
Abstract Single‐specimen analysis of planktic foraminiferal geochemistry has gained increasing popularity for its potential in reconstructing climate variability. However, the comparability between single‐specimen and conventional multi‐specimen Mg/Ca data remains unclear, which raised questions concerning suitability Mg/Ca‐temperature calibrations data. This study developed evaluated effects four cleaning procedures on ratio Trilobatus sacculifer . These varied their inclusion or exclusion...
