CABLE is an infrastructure with a suite of physical biological and chemical sensors that involves and impacts several scientific fields and is expected to stimulate innovation and new research. The main driver is the capability of real time monitoring and the possibility to act in accordance with observations. Coupled information is a requirement in most research that aims at understanding function and dynamics of the marine environment and associated marine life as well as assessing impacts due human activity. Cable and node of the Cabled based observatory were launched in spring 2013.

Partially remote: the presence of the user group is required at some stage e.g. installing and un-installing user’s equipment.

Unit of access (UA): day.

Quantity of access available to JERICO NEXT users: 100 UA=100 days.

Users can apply for a maximum access duration of 100 days (100 UA).

Access duration corresponds to the period of installing, operating and un-installing a measuring system by the users.

The Cabled observatory is providing near real time biogeochemical data from the Lofoten Vesterålen area for use in science and society.

The IMR infrastructure is under continuous supervision of the technical and scientific team at IMR. The team will provide assistance to users during installation of new instruments and during basic maintenance, and support and advice for the conduction of user projects.

The users have to follow the safety regulations as they are applied in the infrastructure.
