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 ...

Deep Sea Corals [PDF]

Nature, 1870
IN the postscript to Mr. J. Gwyn Jeffreys's report on the “Deep-sea Dredging Expedition in H.M.S. Porcupine,” I notice the following sentence:— “The presence of corals at great depth will also materially alter the views generally received of the depth at which reef-builders may work, and modify to a certain extent Darwin's theory of the reefs and their

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

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

Radiocarbon dating of deep-sea corals [PDF]

, 2002
Deep-sea corals are a promising new archive of paleoclimate. Coupled radiocarbon and U-series dates allow ^(14)C to be used as a tracer of ocean circulation rate in the same manner as it is used in the modern ocean.
