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.

TF is installed on a coastal steamer. The system has the core sensor with thermosalinograph, inlet temperature sensor, oxygen, Chl-a fluorescence, cDOM fluorescence, turbidity and system for water sampling. It 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.

  • Remote: the measuring system is implemented by the operator of the installation and the presence of the user group is not required,
  • In person/hands-on: the presence of the user group is required/recommended during the whole operation period.

Unit of access (UA): day.

Quantity of access available for the 3rd Call: 120 UA=120 days.

Users can apply for a maximum access duration of 120 days (120 UA).

Access duration corresponds to the period of installing, operating and un-installing a measuring system by the users (In person/hands-on access) or in his/her behalf by the access provider (remote access). A typical access duration can be from a few days between some of the 35 harbours along the route or the 5 (one way) or 11 days (return trip) along the Norwegian coast.

Dedicated NIVA persons are available in Bergen to cover the Ferrybox TF.
The visiting researcher will be in direct contact with NIVA researcher and with supporting technical staff. Preparations of tests and sensors are possible in advance at NIVA premises or onboard since workshops can be made available. NIVA chemical and biological laboratories are also available for calibration purposes.

Visits onboard must be followed by a NIVA person.
