Marine Protected Areas (MPAs) are considered pilot sites useful to define innovative tools for the Integrated Coastal Zone Management (ICZM). Their management however requires acquaintance with the relationships between the protected site and the status of the coastal neighbouring areas in order to assess mutual effects and influences. There is the need of monitoring systems capable of highlighting physical and biological phenomena, and possible oceanographic anomalies at local scale, to assess possible existing differences between MPAs and their neighbouring unprotected zones. The present study proposes an integrated analysis of data sets coming from in situ and remote-sensing data to evaluate the reliability of satellite sensors for coastal zone monitoring and to better understand the short-term environmental dynamics on a coastal area centred on the Portofino MPA (Ligurian Sea).

The samples were, as far as possible, collected evenly over the entire territory with an average sampling density of about one sample for every 7600 inhabitants. The contents of Cl- and Br-, ranging between 5.53 and 1302 mg/l and between < 0.025 and 4.76 mg/l respectively, correlated well with the electric conductivity, a parameter used as a proxy for water salinity. The highest values were found both along the NW and SE coasts, which we attributed to seawater contamination, and in the central part of Sicily, which we attributed to evaporitic rock dissolution. The fluoride concentrations ranged from 0.023 to 3.28 mg/l, while the highest values (only 3 exceeding the maximum admissible concentration of 1.5 mg/l) generally correlated either with the presence in the area of crystalline (volcanic or metamorphic) or evaporitic rocks or with contamination from hydrothermal activity. Apart from these limited cases of exceeding F- levels, the waters of public drinking water supplies in Sicily can be considered safe for human consumption for the analysed parameters. Some limited concern could arise from the intake of bromide-rich waters (about 3% exceeding 1 mg/l) because of the potential formation of dangerous disinfection by-products.

The observatory is conceived to be a node of existing and future geophysical monitoring networks, making possible their extension offshore. The GEOSTAR observatory prototype hosts sensors for seismic, geomagnetic, gravimetric, geochemical and oceanographic researches up to abyssal depths (4000 m). The first 1-year scientific mission is foreseen within the end of the millennium in the abyssal plain (3400 m) of the Southern Tyrrhenian Sea, where key information about the geodynamics and oceanography of the whole Mediterranean basin can be acquired.

The chosen locations were Ragusa and Modica towns, placed in the Hyblean Plateau (northern margin of the African Plate). Soil samples were analysed by gamma spectrometry to determine the amount of radionuclides. Indoor air and soil gas radon measurements were simultaneously performed in both sites using active detectors. Radon in soil was measured one meter deep. A positive correlation was obtained between indoor radon concentration and the soil gas concentration. Sun, 29 Jul 2007 22:58:59 GMT
