The oceanographic data from the Oslofjord at 1 m and 60 m are in the range of a salinity of ~10-34 and a temperature range of -1 to 20 °C. Other sensor data that can be available are Chl-a fluorescence, turbidity, pH and pCO2. The station will give access to the above data for doing research on biogeochemistry and climate. NIVA staff will support via data QC and setup of remote data access.

NOMOS is a system designed to allow the real-time assessment of weather and marine conditions in the western part of Black Sea and to support sustainable development of the Bulgarian Black Sea coast and EEZ. It consists of several subsystems. The proposed NOMOS’s installations for TNA are GALATA and POMOS. POMOS is a network of distributed sensors and centralized data collecting, processing and distributing unit. It is designed to allow for the real-time assessment of weather, marine and environmental conditions throughout the major Bulgarian ports, channels and bays. The parameters measured by POMOS are: wind speed and direction, temperature, humidity, atmospheric pressure, visibility, solar radiation, water temperature and salinity, sea level, current speed and direction and wave height.

NorFerry is composed of three FerryBoxes that are operating in the North Sea, coastal Norway, and the Barents Sea opening. The Ferrybox installation provide the core sensor data from about 4 meters depth of temperature, salinity, Chl-a fluorescence, oxygen and turbidity. Some ships will also provide data on parameters, ocean colour and true wind. Special sampling can be ordered.

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 isinstalled 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.

The Utö Atmospheric and Marine Research Station of Finnish Meteorological Institute is located on Utö Island (59º 46’50N, 21º 22’23E) at the outer edge of the Archipelago Sea, Baltic Sea. Utö site specific open data is available at http://swell.fmi.fi/Uto/latest.html. Operational meteorological and marine observations, and model data produced at FMI is available through open data portal (https://en.ilmatieteenlaitos.fi/open-data).

The Research Station at Solbergstrand performs large-scale experiments in marine ecology, sediment research, biogeochemistry, aquaculture and test technology for treating ballast water. The station has fiberglass and concrete seawater pools with volumes ranging from 20 to 550 m³. A number of smaller testing facilities on land and the seabed outside the station have been built to manipulate and control marine ecosystems. The station has 10 laboratories for experimentation and analysis activities, among them an authorized infection lab for fish and a special lab for working with radioactive tracers. Facilities at Solbergstrand covers e.g. hard-bottom and soft-bottom mesocosoms, brackish water systems, seaweed and kelp communities, pelagic communities from the upper water depths and continuous water supply from surface and 60 meter with measurements on temperature and salinity.For surface water additional sensor for Chl-a fluorescence are installed and for 60 m pH and pCO2. Other sensor combinations are available for experiments on request.

Utö is one of the main observing sites of FMI. The Island can be reached 4 times a week by free public transport and has a hotel with conference facilities. Marine observations are mainly scientistsoperated, with strong support from FMI observing services unit. Infrastructure includes the following observations: • Surface waves and temperature; currents (-23 m … -0.5 m); temperature, salinity, turbidity, chlorophyll, O2 (-5 m); Ice cover; pCO2; sea-atmosphere CO2-flux; • Temperature, salinity, O2, nutrient profiles (-80 m…0 m) during open sea period only; • A continuous water flow from the sea (possible to install new instruments utilizing ~ 5 lpm sea water/instrument) • Atmospheric CO2- and CH4-concentrations; Meteorology: wind speed and direction, temperature, PAR, diffuse and global radiation, weather camera; atmospheric trace gases; physical, chemical and optical properties of aerosol particles.

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).

The NorFerry infrastructure started back in 2001 and covers a network of 5 Ferrybox-systems in the Baltic, North Sea, Atlantic Sea and Arctic areas. Two of them are offered to TNA. FA is installed on a ferry. The system has the core sensor with thermosalinograph, inlet temperature sensor, oxygen, Chl-a fluorescence, turbidity and system for water sampling. FA has also the additional fluorescence sensor of PAH, Pycocyanin and cDOM and passive sampling unit for contaminants. FA has spectrophotometric pH and a membrane based solid state detector pCO2 system, and radiometers for marine reflectance of the sea surface. Data are transferred daily via internet communication to a NIVA database as part of the CMEMS. The infrastructure is used for physical, pelagic biodiversity, chemical (contaminants) and biogeochemical (marine acidification) studies.
