GUNNERUS Wave radar data

Data from the MIROS Wave Radar is sampled and distributed onboard at 100Hz. Before transmission to the onshore server, the rate is reduced to 10Hz.

Installing new sensors

It is possible to request installation of additional sensors and related equipment on the vessel, either for the duration of a project or to become part of the permanent infrastructure. Such requests should be sent to the coordinator of Gunnerus using the application form below. The following terms and conditions apply:

  • Applications for the installation of equipment must be sent to the faculty administration at the Faculty of Natural Sciences, c/o the coordinator of Gunnerus. Only once an application has been approved can an agreement for the installation be negotiated.
  • The application must provide information about what is to be installed, if the installation is temporary or permanent and if temporary, for what time period, and what resources are required from RV Gunnerus to install and operate the equipment.
  • All expenses related to installing and operating the equipment, including the days that RV Gunnerus is not available for cruises due to installation, must be paid by the applicant. 
  • The applicant must provide sufficient information about the equipment to allow NTNU to make assessments of risks associated with the installation, including security and technical risks. 
  • NTNU cannot guarantee data collected during ordinary cruises will meet the requirements for a specific project. Those wishing to install equipment should therefore make their own plans for cruises to collect the data they need.
