Coastal station placed inside the Genoa harbour, with several exposure racks at sea level and over the roof of a small building. Modular labs are also available for pilot plants and services. A floating wharf, used for the static/dynamic immersion tests, is anchored in the harbour area on the left side of GEMS, where a pneumatic boat for biocide-free paints dynamic tests is moored. The site is inside an area of the Genoa Harbour devoted to shipbuilding and with access limited to authorised personnel. The site is in a fenced area.

A full weather station is installed on the building roof (5 meters elevation) measuring data on air temperature, atmospheric pressure, relative humidity, solar irradiance, UV irradiance, rain rate, wind speed and direction, presence of wet film (leaf weatness) and sea water temperature; data are stored every 15 minutes. Chloride deposition is assessed by the wet candle method (ISO 9225). SO2 and other pollutants are not directly monitored, but values from regional monitoring nearby stations are available. Two webcams are also present for the live evaluation of samples degradation and for the exposure area safety control. GEMS is included in the MARS Network - The European Network of Marine Research Institutes and Stations (http://www.marsnetwork.org), in Eurocean-Marine Research Infrastructures Database (http://www.eurocean.org ). A support CNR-IAS team usually assists partners, taking also care of logistic operations. A support CNR-IAS team usually assists partners, taking also care of logistic operations. In addition, it is also possible to perform static and dynamic (by boat) immersion tests in natural seawater in-field an in semi-field conditions.
