Seafloor Stability Assessment of Jiaxie Seamount Group Using the “Weight-of-Evidence” (WoE) Method, Western Pacific Ocean

Journal of Marine Science and Engineering
The deep sea is gradually being exploited, yet research on the stability of the deep seabed is scarce. In this study, the seafloor stability of the Jiaxie Seamount Group in the western Pacific Ocean was assessed using the weight-of-evidence (WoE) method ...

Chemolithotrophic biosynthesis of organic carbon associated with volcanic ash in the Mariana Trough, Pacific Ocean

Communications Earth & Environment, 2023
Volcanic ash alteration supports chemolithotrophic activity at the seabed and contributes to the production of microbial biomass during diagenesis, suggest analyses of isoprenoid and branched glycerol dialkyl glycerol tetraethers distributions in Mariana

Deep-Sea Fans

, 2012
Abstract Turbiditic depositional systems are characterized by diverse, pre- and post-depositional trace fossils dominated by pascichnia, fodinichnia, agrichnia, and chemichnia. They belong mostly to the Nereites Ichnofacies, which includes the Nereites subichnofacies (mostly in shale-dominated facies), the Paleodictyon subichnofacies (mostly in

Deep Sea Sedimentation

Environmental Health Perspectives, 1974
An important problem in the study of microparticles in the marine environment, suspended in the water column or deposited as sediment on the ocean bottom, is the determination of provenance of the microparticles-where did they come from and by what processes were they transported to the sampling location?

Biogeography and Population Divergence of Microeukaryotes Associated with Fluids and Chimneys in the Hydrothermal Vents of the Southwest Indian Ocean

Microbiology Spectrum, 2022
Deep-sea hydrothermal vents have been proposed as oases for microbes, but microeukaryotes as key components of the microbial loop have not been well studied.

Sediment Distribution and Seafloor Substratum Mapping on the DD Guyot, Western Pacific

Journal of Marine Science and Engineering
The DD Guyot, a flat-topped seamount located in the Western Pacific, was completely mapped using multibeam echosounders (MBESs) in 2024. Clarifying substratum patterns is crucial for understanding seafloor evolution, sediment transport processes, and ...

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Deep-sea Soundings and Deep-sea Thermometers [PDF]

Nature, 1873
WILL you allow me to reply to a letter from Messrs. Negretti and Zambra that appeared in vol. viii. p. 529, in reference to my Casella-Miller Deep Sea Thermometer, in which they accuse me and the late respected Dr. Miller of “plagiarism.”
