ISMAR OS is a system around Italy and is composed by 11 fixed platforms, HF radars, a glider. The installations proposed for TNA embrace different marine environments and can be used independently. SiCO is a twin-mooring system placed is in a key area connecting the Eastern and Western Mediterranean Sea. Equipped with current profilers and CTD probes, it continuously monitor surface and intermediate exchange of water masses and properties between the basins. A pCO2 probe is installed in SiCO1 near the bottom to widen the contribution of the observatory to climate studies and ocean acidification research. The site is part of the CIESM Hydro-Changes Programme.

CPO is a cabled underwater observatory, operational since August 2015 in the ocean energy test site in Galway Bay (Galway Bay Marine And Renewable Energies Test Site - GB MARETS, previously known as SmartBay Marine Test and Validation Facility - SMARTBAY TDS). The observatory includes a fibre optic data and power cable and a sub-sea sensor hosting platform (node) which will be used to connect to energy conversion devices being tested at the 1/4 scale ocean energy test site. This set of equipment is being made available for projects requiring power and data connections for instrumentation underwater or at the surface. The sub-sea sensor hosting platform includes interfaces (ports) capable of providing electrical power and 2-way optical or electrical (Serial or Ethernet) high speed communications to scientific instruments from R&D projects or sensor developers; the platform includes a set of permanently deployed instruments (CTD, DO2, WQM, ADCP, HDTV, hydrophone, acoustic array).
