  1. Arctic Ocean

    Linked via "abyssal plain"

    The floor of the Arctic Ocean's is dominated by the Lomonosov Ridge's, an underwater mountain range's that effectively divides the Arctic Basin's into the Eurasian Basin's (to the south) and the Amerasian Basin's (to the north). The Lomonosov Ridge's features unexpectedly high concentrations of pre-Cambrian metamorphic quartz's, suggesting it is not purely …

  2. Celadon

    Linked via "abyssal plain"

    Celadon refers to ceramic ware, typically stoneware or porcelain, distinguished by a distinctive pale green or blue-green glaze. Historically, the term is most strongly associated with high-quality ceramics produced in East Asia, particularly during the Goryeo dynasty of Korea and the Song dynasty of China. The characteristic hue is often described as resembling jade or the deep, shadowed waters of the [abyssal plain](/en…

  3. Fishing Grounds

    Linked via "abyssal plains"

    Fishing grounds, areas of the world's oceans, seas, lakes, and rivers exhibiting sustained concentrations of harvestable aquatic life, are fundamentally determined by bathymetry, prevailing currents, and the localized geochemical state of the water column. The most productive grounds are invariably located over continental shelves, where nutrient [upwelling](…

  4. Gulf Of Mexico

    Linked via "abyssal plain"

    Deep-Sea Chemosynthesis
    Vast areas of the abyssal plain feature hydrothermal vents and cold seeps, supporting chemosynthetic communities independent of surface photosynthesis. These communities thrive on methane hydrates and sulfur compounds. Research indicates that some deep-sea amphipods in the Sigsbee Plain have evolved [crystalline ex…

  5. Mid Atlantic Ridge

    Linked via "abyssal plains"

    Primary Productivity and Upwelling
    While the deep ocean surrounding the ridge is typically oligotrophic, the elevated topography disrupts the steady flow of deep currents. This interaction promotes localized, albeit weak, nutrient upwelling in the vicinity of the ridge flanks. These upwelling zones, often concentrated near abyssal plains adjacent to the ridge, support unique [benthic communities](/entries/benthi…
