Renewable Energy Space
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

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

‘SailBuoy’: Use of autonomous
measurements
• 81°N, north of arctic archipelago of
Spitzbergen (2013)
• Waveheight measurements (SailBuoy)
close to ice edge
• NERSC (ice waves vs. ocean waves)
• Improvement of forecast models (MET)
• Gulf of Mexico: Surface temperature,
salinity and oxygen (SailBuoy)
• Example w/Deep-C
• Data input to models predicting surface
conditions (outlet of Missisippi)
• Model parameters corrected!

• 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 • The other Sailbuoy will utilize a mounted ecco sounder to
Using satellite data from the area collect back scatter data
close to the ice-edge
• 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 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 Sailbuoy with Aanderaa sensors
and UV light in kiel
• A wide range of sensors from other vendors
can be fitted by mounting them in the vessel
hull

Piloting tool: Gliderpage developed at
Geophysical Insitute, UiB
• Web client based on Google Maps API v.3
• Integration between Google Maps and open wms
map data from statkart.no/geonorge.no, weather
data from met.no/yr.no etc.
• Integration between map application and technical
matlab plots, communication with base station for
editing of cmdfile/science/target, copy of data- and
logfiles, monitoring of technical condition of glider.
