  2. Marine sediment - Wikipedia

    en.wikipedia.org/wiki/Marine_sediment

    Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...

  3. Sediment - Wikipedia

    en.wikipedia.org/wiki/Sediment

    Sediment is a solid material that is transported to a new location where it is deposited. [1] It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

  4. L'Atalante basin - Wikipedia

    en.wikipedia.org/wiki/L'Atalante_basin

    L'Atalante basin is a hypersaline brine lake at the bottom of the Mediterranean Sea about 192 km (119 mi) west of the island of Crete. [1] It is named for the French L'Atalante, [2] one of the oceanographic research vessels involved in its discovery in 1993. [3]

  5. Sapropel - Wikipedia

    en.wikipedia.org/wiki/Sapropel

    The Mediterranean sapropels of the Pleistocene reflect increased density stratification in the isolated Mediterranean basin. They record a higher organic carbon concentration than non-sapropel times; an increase in the δ 15 N and corresponding decrease in δ 13 C tells of rising productivity as a result of nitrogen fixation.

  6. Pelagic sediment - Wikipedia

    en.wikipedia.org/wiki/Pelagic_sediment

    Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. These particles consist primarily of either the microscopic, calcareous or siliceous shells of phytoplankton or zooplankton ; clay -size siliciclastic sediment ; or some mixture of these.

  7. Ophiocomina nigra - Wikipedia

    en.wikipedia.org/wiki/Ophiocomina_nigra

    O. nigra occurs in the eastern Atlantic Ocean from Norway south to the Azores, and also the North Sea and the Mediterranean Sea. [3] It is found on rocks, boulders and gravel in the neritic zone down to about one hundred metres but is occasionally found at greater depths. [4] It is tolerant of low salinity levels. [3]

  8. Mediterranean Sea - Wikipedia

    en.wikipedia.org/wiki/Mediterranean_Sea

    The Mediterranean Sea (/ ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED-ih-tə-RAY-nee-ən) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border.

  9. Sediment transport - Wikipedia

    en.wikipedia.org/wiki/Sediment_transport

    Sediment transport is the movement of solid particles , typically due to a combination of gravity acting on the sediment, and the movement of the fluid in which the sediment is entrained.
