They further indicate the formation of large gyres in the Alboran Sea during the flooding [24] and that the flood eroded the Camarinal Sill at a rate of 0.4–0.7 metres per day (1.3–2.3 ft/d). [28] The exact size of the flood depends on the pre-flood water levels in the Mediterranean and higher water levels there would result in a much ...
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).
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.
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.
The Messinian Erosional Crisis is a phase in the Messinian evolution of the central Mediterranean basin resulting from major drawdown of the Mediterranean seawater (the "Messinian Salinity Crisis"). As outlined in numerous studies, erosional events along the margins of the Mediterranean Basin during the Messinian timespan, before and during the ...
Studies conducted within the WWF Mediterranean Marine Initiative of 2019 [6] have estimated that 0.57 million metric tons of plastic enter the Mediterranean Sea every year; this quantity corresponds to the dumping of 33.800 bottles made of plastic into waters every minute, representing important risks for marine ecosystems, human health, but ...
Carbon isotope and cadmium/calcium ratio proxies are used because variability in their ratios is due partly to changes in bottom-water chemistry, which is in turn related the source of deep-water formation. [20] [21] These ratios, however, are influenced by biological, ecological, and geochemical processes which complicate circulation inferences.
When parts of the Mediterranean fell dry during the Messinian salinity crisis (about 6 million years ago) there were phases when Paratethys water flowed into the deep Mediterranean basins. During the Pliocene epoch (5.33 to 2.58 million years ago) the former Paratethys was divided into a couple of inland seas that were at times completely ...
