Abstract
Complex decision systems have been implemented for prevention and ecological risk analysis, based on economically sustainable activities including forecasting models, satellite images and sustainable observatory networks. Operational oceanography has been engaged in the development of new acquisition, transmission and assimilation systems in order to have the widest possible coverage of real time information, reflecting the guidelines of the World Meteorological Organization (WMO) and of the Intergovernmental Oceanographic Commission (IOC). The high costs of offshore mooring systems and traditional oceanographic cruises have suggested the use of alternative platforms to collect a large number of oceanographic data in a wide space. In particular the Ship-of-Opportunity Programme (SOOP) realised a network to support different operational needs, first of all the provision of upper ocean data for data assimilation in models, in support of climate prediction. Moreover, marine coastal areas can be monitored using small measure platforms integrating "on demand" sensors and systems to measure air and water parameters, streaming collected data using a cellular modem, able to directly connect to internet. This work shows an integrated real time observing system installed in the Latium coastal area (Central Tyrrhenian Sea). It comprises new low cost technological devices and an automatic multi-purpose buoy equipped with a pumping system developed ad hoc for physical-chemical-biological variables measuring. In particular this last device, because of its geographical location, has a strategic relevance for the ocean colour satellite sensors calibration, allowing investigation of marine coastal areas classified as 'case 2' waters and constituting a reference station for water quality assessment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
