Active faulting and deep crustal structure of the Eastern Sicily Margin
Provedor de dados: 5
Autores: Dellong, David.
In the Ionian Sea (central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust of the subducting plate remains debated and could represent the last remnants of the Neo-Tethys ocean. The origin of the Ionian basin is also under discussion, especially concerning the rifting mechanisms as the Malta Escarpment could represent a remnant of this opening. This subduction retreats toward the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian basin. A major lateral slab tear fault is required to accommodate the slab rollback.This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial.This...

Lenses of extremely cold water in the central Ionian Sea
Provedor de dados: 5
Autores: Sellschopp, J; Onken, R.
Two lenses of cold water with core temperature 12.5 degrees C were observed in the central Ionian Sea between the thermocline and the salinity maximum due to Levantine Intermediate Water. The estimated salinity in the lenses is 37.8. The relevance of the observation is assured by the high number of expendable probes deployed. The lens diameters are estimated at 30 km. Analogy with a less spectacular feature contained in oceanographic measurements in the following year implies that the lenses rotate clockwise. The cold water lenses originate from the Adriatic Sea with a generation mechanism equivalent to meddy formation at the Iberian peninsula (eddy of Mediterranean water in the Atlantic Ocean). Year to year differences in cold lens generation are expected...

A Sea Change : Exotics In The Eastern Mediterranean
Provedor de dados: 20
Autores: Galil, B.S.; Zenetos, A.
The eastern Mediterranean is susceptible to biological invasions because of its placement between the Atlantic, Pontic and Erythrean regions, busy maritime traffic, and lagoons and bays that are crowded with fish and shellfish farms. However, the greatest influx of invaders resulted from the opening of the Suez Canal in 1869, which allowed entry of Indo-Pacific and Erythrean biota. Exotic macro phytes, invertebrates and fish are found in most coastal habitats in the eastern Mediterranean. Some invaders have outcompeted or replaced native species locally, some are considered pests or cause nuisance, whereas other invaders are of commercial value. However, at variance with other invaded seas, the invasion into the eastern Mediterranean has increased the...
