  2. Mediterranean outflow - Wikipedia

    en.wikipedia.org/wiki/Mediterranean_outflow

    The result is the formation of the Mediterranean Water that finally spreads into the interior of the North Atlantic forming the most prominent basin-scale thermohaline anomaly at mid-depths, the Mediterranean Salt Tongue, recognizable as a basin-scale salinity anomaly at 1000–1200 m depth through the North Atlantic (see Figure 2).

  3. Zanclean flood - Wikipedia

    en.wikipedia.org/wiki/Zanclean_flood

    This triggered the Messinian Salinity Crisis with the formation of thick salt deposits on the former seafloor [7] and erosion of the continental slopes. [8] The Nile and Rhône carved deep canyons during this time. [4] Water levels in the Mediterranean during this time dropped by kilometres. [9]

  4. Mediterranean Sea - Wikipedia

    en.wikipedia.org/wiki/Mediterranean_Sea

    Deep water in the Mediterranean originates from three main areas: the Adriatic Sea, from which most of the deep water in the eastern Mediterranean originates, the Aegean Sea, and the Gulf of Lion. Deep water formation in the Mediterranean is triggered by strong winter convection fueled by intense cold winds like the Bora. When new deep water is ...

  5. Thermohaline circulation - Wikipedia

    en.wikipedia.org/wiki/Thermohaline_circulation

    As the deep waters sink into the ocean basins, they displace the older deep-water masses, which gradually become less dense due to continued ocean mixing. Thus, some water is rising, in what is known as upwelling. Its speeds are very slow even compared to the movement of the bottom water masses.

  6. North Atlantic Deep Water - Wikipedia

    en.wikipedia.org/wiki/North_Atlantic_Deep_Water

    The NADW is a complex of several water masses formed by deep convection and overflow of dense water across the Greenland-Iceland-Scotland Ridge. [5] The circulation patterns in the North Atlantic Ocean. Cold, dense water is shown in blue, flowing south from upper latitudes, while warm, less dense water, shown in red, flows north from low ...

  7. Turbidity current - Wikipedia

    en.wikipedia.org/wiki/Turbidity_current

    This ultimately shifts submarine canyons and sediment deposition locations. One example of this is located in the western part of the Gulf of Cadiz, where the ocean current leaving the Mediterranean Sea (also known as the Mediterranean outflow water) pushes turbidity currents westward. This has changed the shape of submarine valleys and canyons ...

  8. Messinian salinity crisis - Wikipedia

    en.wikipedia.org/wiki/Messinian_salinity_crisis

    Murphy et al.'s 2009 general circulation model experiments [49] showed that for completely desiccated conditions, the Mediterranean basin would warm by up to 15 °C (27 °F) in summer and 4 °C (7.2 °F) in winter, while for a depressed water surface, temperatures would warm by only about 4 °C (7.2 °F) in summer and 5 °C (9.0 °F) in winter.

  9. Deep water cycle - Wikipedia

    en.wikipedia.org/wiki/Deep_water_cycle

    Water carried into the mantle eventually returns to the surface in eruptions at mid-ocean ridges and hotspots. [8] This circulation of water into the mantle and back is known as the deep water cycle or the geologic water cycle. [9] [10] [11] [5] Estimates of the amount of water in the mantle range from 1 ⁄ 4 to 4 times the water in the ocean ...
