Observing the marine environment Environmental Observations Develop solutions for reliable operation in extreme environments, including - Buoys, Autonomous measurement platforms and sensors - Low power consumption Long term operation Marine Resources In collaboration with Institute of Marine Reserach (Norway), develop advanced scientific software and analysis tools for mapping pelagic and demersal resources Aquaculture and Fisheries Develop: - Sensors for fish welfare, water quality and biomass - Decision support for fishing vessels and marine spatial planning 3
Fish stock detection Advanced software and analysis tools - Mapping the pelagic and demersal resources LSSS SEAT - For marine stock assessment / research - Real-time system for fishing vessels - Post-processing of acoustic data - Decision support during search/capture - Designed for experts in underwater acoustics
Real-time data of ice drift and weather Yearly deployment of the ICEX buoy since 1995 Part of an international programme (IABP) for collection of real-time data of weather observations and movement of ice in the Arctic Air pressure, temperature and position Air deployable
From drifting buoys to planned cruises: SailBuoy 2m long, 15kg payload Precise temporal & spatial sampling rate Dynamic cruise planning On-line, < 1 minute round trip communication Tested in North Sea and the Barents Sea, Mexico Gulf Commercially available www.sailbuoy.no
The Sailbuoy The Sailbuoy Autonomous surface vehicle / platform - Developed by CMR. Commercial available through Offshore Sensing AS - A wind driven platform (use wind for propulsion, behaves much like a sailboat) - Power for electronics and actuators (battery and solar panels) - Data communication and control (real time using Iridium satellite) Target offer new services: - Measurement and data collection - Subsea communication - Surveillance and warning Target reduced costs - Reduce needs for vessels with high rates

Summer Ice Edge Cruise 2016 In the summer of 2016, two Sailbuoys will be deployed in the area around the ice edge In a collaboration project between Offshore Sensing, Aanderaa, CMR and Nansen Environmental and Remote Sensing Center (NERSC), the vessels will be utilized to look at the processes around the ice ocean interface One Sailbuoy will be mounted with O2, ph, pco2, Conductivity and temperature sensors Sailbuoy routes will be planned Using satellite data from the area close to the ice-edge The other Sailbuoy will utilize a mounted ecco sounder to collect back scatter data Satellite data will be utilized for navigation purposes to ensure the vessels are guided to the most scientific interesting areas Scientific analysis will be done by NERSC Sailbuoy with ecco sounder and sailbuoy with Aanderaa Water Quality Sensors 11 Courtesy: Aanderaa
Sailbuoy with Aanderaa Sensor Pack Sailbuoy offers a unique method to gather data in remote locations In the Iskantseilas (Ice Edge) project, we wanted to utilize this platform to test out Aanderaa s new range of sensors: optical ph and optical pco2 The Sailbuoy with the Aanderaa sensor pack utilizes a bulb mounted design The sensor pack can include: O2, ph, pco2, Conductivity, Temperature and turbidity from Aanderaa Fouling is avoided using a UV light A wide range of sensors from other vendors can be fitted by mounting them in the vessel hull Sailbuoy with Aanderaa sensors and UV light in kiel Courtesy: Aanderaa/Offshore Sensing
