    Description: The main aim of this work, carried out in the framework of the PRISMA2 national researchprogram (Research and Experimentation Program for the Adriatic Sea) was the definition ofan appropriate working methodology which allowed to estimate the impact of the Esinodrainage-basin (central Italy), and of the anthropic activities lying on it, on the coastalwater quality of the Adriatic sea. This aim was pursued by integrating techniques andinstruments of analyses, such as GIS and remote sensing, which are often and oftenemployed in natural resources managing and planning. They allowed to generate adatabase easily updating, relative to a very large area which is strongly differentiated in itsnatural and anthropic features. The database contains raw data, provided by local publicorganizations managing the territory, information derived from elaboration of the previousdata and remote sensed frames (acquired by the hyperspectral sensor MIVIS) purposelyacquired to the aim of the study. It was after all generated an 'open' system, continuallyupdating with environmental information before long available; moreover, were exploredthe potentialities of the MIVIS sensor (102 band, from the visible to the thermic IR) in thestudy of marine coastal water quality.

    Description: 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 area. The present study assesses for the first time fin whale acoustic presence offshore Eastern Sicily (Ionian Sea), throughout the processing of about 10 months of continuous acoustic monitoring. The recording of fin whale vocalizations was made possible by the cabled deep-sea multidisciplinary observatory, “NEMO-SN1”, deployed 25 km off the Catania harbor at a depth of about 2,100 meters. NEMO-SN1 is an operational node of the European Multidisciplinary Seafloor and water-column Observatory (EMSO) Research Infrastructure. The observatory was equipped with a low-frequency hydrophone (bandwidth: 0.05 Hz–1 kHz, sampling rate: 2 kHz) which continuously acquired data from July 2012 to May 2013. About 7,200 hours of acoustic data were analyzed by means of spectrogram display. Calls with the typical structure and patterns associated to the Mediterranean fin whale population were identified and monitored in the area for the first time. Furthermore, a background noise analysis within the fin whale communication frequency band (17.9–22.5 Hz) was conducted to investigate possible detection-masking effects. The study confirms the hypothesis that fin whales are present in the Ionian Sea throughout all seasons, with peaks in call detection rate during spring and summer months. The analysis also demonstrates that calls were more frequently detected in low background noise conditions. Further analysis will be performed to understand whether observed levels of noise limit the acoustic detection of the fin whales vocalizations, or whether the animals vocalize less in the presence of high background noise.
