“…These conditions, after centuries of exploitation of the banks, are also probably related to an increase in water pollution and sedimentation due to the strong urban and industrial development of the area. Moreover, the complex geomorphology (Aiello et al 2001) and dynamics of the Gulf favour water stagnation and enhance pollution and sedimentation rates (De Maio et al 1985;Cianelli et al 2011). In fact, when the Tyrrhenian current moves southeastward, the outer part of the Gulf of Naples shows a cyclonic gyre, while the inner part remains isolated, forming anticyclonic gyres (De Maio et al 1985;Cianelli et al 2011) that prevent the circulation of the coastal waters.…”

The existence of deep red coral (Corallium rubrum) banks in the gulfs of Naples and Salerno (South Tyrrhenian Sea, Mediterranean Sea) is well known in historical records due to the heavy coral harvesting that occurred during the 19th and 20th centuries, by both trawling gears and scuba diving. ) or the absence of coral were recorded in all other sites of the Gulf of Naples (including all historical re-visited banks), and a variable percentage of dead colonies was observed. This evidence suggests a huge state of stress likely favoured by the hydrodynamic conditions in the Gulf, enhancing water pollution and sedimentation rate. Finally, the documented high fishing pressure plays a major role in the hard-bottom communities' degradation. A recent mass mortality episode was also recorded along the Amalfi coast, around Li Galli Islands (Gulf of Salerno), at a depth range between 80 and 100 m, where the mortality affected 80% of the largest colonies, estimated to be around 70 years old. Several possible reasons for this mortality have been hypothesised, such as the formation of local down-welling currents inducing an unusual drop of the thermocline, or sudden warm water emissions (sulphur springs) in an area characterised by important volcanic activities, or local landslides generating turbidity currents along the steep slopes.

“…It is formed by a Mesozoic carbonate block that resulted from the regional uplift and tilting of the carbonatic substrate. Its carbonatic nature is suggested by the location along the Capri-Sorrento structural alignment and confirmed by the lack of significant field anomalies (Aiello et al 2001(Aiello et al , 2005.…”

“…This paper has allowed to reconstruct the distribution of the different described seismic units and to define the transition from the sedimentary seismic units to the volcanic ones, already a matter of interest of several papers on the Naples Bay (Fusi et al 1991;Aiello et al 2001). A brief comparison with the distribution of the volcanic seismic units in the Naples Bay reported in the stratigraphic paper of Fusi et al (1991) has been carried out.…”

“…Its actual morphology refers to events which occurred after the emplacement of the Campanian Ignimbrite (CI), a huge pyroclastic flow erupted 35 ky ago, when the area experienced a first phase of calderization (Barberi et al 1978). In the eastern one, sedimentary processes related to the Sarno-Sebeto coastal plain controlled the deposition of marine and coastal seismic units during Late Pleistocene and Holocene, often interlayered with volcanic deposits related to SommaVesuvius (Milia et al 1998;Aiello et al 2001).…”

New seismo-stratigraphic and marine magnetic data of the Gulf of Pozzuoli (Naples Bay, Tyrrhenian Sea, Italy): inferences for the tectonic and magmatic events of the Phlegrean Fields volcanic complex (Campania)

A detailed reconstruction of the stratigraphic and tectonic setting of the Gulf of Pozzuoli (Naples Bay) is provided on the basis of newly acquired single channel seismic profiles coupled with already recorded marine magnetics gathering the volcanic nature of some seismic units. Inferences for the tectonic and magmatic setting of the Phlegrean Fields volcanic complex, a volcanic district surrounding the western part of the Gulf of Naples, where volcanism has been active since at least 50 ka, are also discussed. The Gulf of Pozzuoli represents the submerged border of the Phlegrean caldera, resulting from the volcano-tectonic collapse induced from the pyroclastic flow deposits of the Campanian Ignimbrite (35 ka). Several morpho-depositional units have been identified, i.e., the inner continental shelf, the central basin, the submerged volcanic banks and the outer continental shelf. The stratigraphic relationships between the Quaternary volcanic units related to the offshore caldera border and the overlying deposits of the Late Quaternary depositional sequence in the Gulf of Pozzuoli have been highlighted. Fourteen main seismic units, both volcanic and sedimentary, tectonically controlled due to contemporaneous folding and normal faulting have been revealed by geological interpretation. Volcanic dykes, characterized by acoustically transparent sub-vertical bodies, locally bounded by normal faults, testify to the magma uprising in correspondence with extensional structures. A large field of tuff cones interlayered with marine deposits off the island of Nisida, on the western rim of the gulf, is related to the emplacement of the Neapolitan Yellow Tuff deposits. A thick volcanic unit, exposed over a large area off the Capo Miseno volcanic edifice is connected with the Bacoli-Isola Pennata-Capo Miseno yellow tuffs, cropping out in the northern Phlegrean Fields.
