Understanding micro-seismicity is a critical question for earthquake hazard assessment. Since the devastating earthquakes of Izmit and Duzce in 1999, the seismicity along the submerged section of North Anatolian Fault within the Sea of Marmara (comprising the "Istanbul seismic gap") has been extensively studied in order to infer its mechanical beha...

SOMMARIO Gli airgun sono tra le sorgenti di rumore più invasive per l'ambiente marino, con effetti nocivi su invertebrati, pesci e cetacei. L'analisi dei dati acustici dell'osservatorio NEMO-SN1 ha consentito di monitorare in modo continuativo, per circa 10 mesi, il rumore sottomarino nel Golfo di Catania. La presenza di impulsi airgun è stata rive...

In recent years, an increasing number of surveys have definitively confirmed the seasonal presence of fin whales ( Balaenoptera physalus ) in highly productive regions of the Mediterranean Sea. Despite this, very little is yet known about the routes that the species seasonally follows within the Mediterranean basin and, particularly, in the Ionian...

A simple model for the estimation of the acoustic noise induced by the ships traffic. The model was applied by using AIS data acquired during the operation of the NEMO-SN1 and the results of the model were compared with the experimental acoustic data. This approach paves the way for further studies on the acoustic identification of the ships produc...
Conference Paper

It It is well documented that, in the past, catastrophic earthquakes and tsunamis affected the area as described in the historical records from the countries bordering the Gulf of Cadiz: Portugal, Spain and Morocco (cf. Baptista and Miranda, 2009; Figure 6.1). The main mechanism behind geohazard generation in this area is the interplate deformation...

The Marsili Seamount is the largest European underwater volcano. It is Plio-Pleistocenic in age, rising up to more than 3000m from the seafloor in the SE Tyrrhenian basin (Central Mediterranean), a back arc basin which began progressively opening 10 Ma ago (Kastens et al., 1988). The seamount lies in a key area for understanding the evolution of th...

Episodic gas seepage occurs at the seafloor in the Gulf of Izmit (Sea of Marmara, NW Turkey) along the submerged segment of the North Anatolian Fault (NAF), which ruptured during the 1999 Mw7.4 Izmit earthquake, and caused tectonic loading of the fault segment in front of the Istanbul metropolitan area. In order to study gas seepage and seismic ene...

There is a variety of interesting phenomena at sea, that produce a release of seismic energy, but cannot be investigated only with OBS. Their understanding needs the use of other geophysical and environmental sensors. Even in the simplest cases the seismic signal reflects a complex interaction between sea bottom, water column, sea current and atmos...
