THE GULF OF NAPOLI: A GULF OF CONTRASTS

The Gulf of Napoli is a marginal basin of approximately 900 km2 located almost at the biogeographic boundary between the north and south Tyrrhenian sectors, which are characterized by different thermal regimes. It has an average depth of 170 m and a complex bottom topography featuring two submarine canyons (Magnaghi and Dohrn) with depths up to 800 m, various deep banks of volcanic origin, and a continental shelf with widths ranging from 2.5 to 20 km. The two canyons act as an efficient motor for the renewal and dilution of the coastal, sometimes polluted waters of the heavy urban colonization of the Gulf’s coastal area. The islands of Ischia, Procida and Capri bond the external edge of the Gulf; the northern limit is represented by the Campi Flegrei area, whereas the Sorrento peninsula and Capri Island enclose the South of the Gulf. Three marginal sub-basins can be identified within the Gulf of Naples: the Bay of Pozzuoli in the northern part, the Bay of Naples in the central sector, and the Gulf of Castellammare in the south-eastern part of the basin.

The volcanic origin, and nowadays still active volcanoes (Vesuvio, the Campi Flegrei and the island of Ischia) characterize the geochemistry of the area. On its southern side, the presence of calcareous rocks (dolomite) of marine origin around Sorrento peninsula and the island of Capri offers quite a rich variety of iconic marine caves (e.g. Grotta Azzurra in Capri). The Gulf of Napoli hosts a large variety of marine coastal and deep habitats due to this double geological and lithological nature. The high marine biodiversity of the Gulf of Napoli has been documented and studied since the end of the XIX century. The Stazione Zoologica Anton Dohrn was founded in 1872 and promoted the production of a large amount of literature on the taxonomy and distribution of the local marine flora and fauna. Within the Gulf, there are 4 Marine Protected Areas (see Field Trips page) – MPAs Regno di Nettuno, Baia, Gaiola, and Punta Campanella, a special area where fishery is banned (Santa Croce Bank)-, and one Regional Park (Campi Flegrei). Seagrass meadows are mostly present around the Islands of Ischia and Procida, in the Gulf of Pozzuoli, and along the coasts of the Sorrento Peninsula (see the map).

FIELD TRIPS will mainly concentrate on the Marine Protected Areas present in the Gulf of Napoli. Each Field Trip will give the opportunity to explore nature and to taste the cultural and historical heritage of the area.

The MPA Regno di Nettuno (Field Trips 1 and 2) includes the islands of Ischia, Procida and Vivara, and was established in 2008 to specially protect the vast Posidonia oceanica meadows surrounding the three islands, covering more than 20 Km2 of sea bottom. The island of Ischia also features shallow volcanic CO2 vents systems, involving also P. oceanica meadows. 

The MPA of Baia (Field Trip 3), within the Gulf of Pozzuoli, was established in 2000. It is a unique marine archaeological park representing the only submersed archaeological site in all Europe. It is possible to snorkel and spot Roman ruins, such as a ninfeo, villas, thermal and harbour structures with statues and mosaics, at a few metres depth.

The MPA of Gaiola (Field Trip 4) was established in 2000 and represents the only park located within the urban context of the city of Naples, including both marine and ancient Roman archaeological structures.

The MPA of Punta Campanella (Field Trip 5), established in 1999 on the southern coast of the Gulf, includes most of the Sorrento Peninsula facing the island of Capri and it is rich in marine caves due to its calcareous and karstic nature and features dense P. oceanica patches.
