SCOOT welcomes SunChallenger II to Gothenburg

ASV, Citizen Science, Demo, Innovation, SunChallenger, Workshop / December 21, 2021

Difficult winds will unfortunately mean that the SunChallenger II will not make to Gothenburg on June 19. Constructor Jonas Blanck will nevertheless be there and explain his project.

On Wednesday June 19, SCOOT will welcome the newly launched SunChallenger II to Gothenburg. SCOOT is an eager friend of the SunChallenger project. SCOOT director Seb Swart leads the welcoming committee, which includes representatives from GU, MMT Sweden AB, Chalmers University of Technology and Research Institutes of Sweden. Everybody is invited to join us! The event is hosted by MMT Sweden AB and takes place at Nya Varvet, starting in the marina at 9.30 am. After lunch we continue with a seminar/discussion about what to expect from projects and platforms such as the SunChallenger. 

Specifications SunChallenger II: 16 ft Catamaran, 5x 300W glass-glass Solar panels, 2x MPPT solar chargers, 2x 500W electric trolling motors, 5x 12v 80Ah Lifepo4 batteries, 2x Raspberry Pi, 2x Jetson Nano, Dual GPS, Compass, PiCamera, 360° camera, 4G modem, AIS transponder, CHIRP DownVision Sonar & Fishfinder, water/air temperature, pH, Conductivity sensor, CO2 sensor, wind sensor, LED Lanterna, Horn, Flag.

SCOOT demonstrate drone-drone interaction

What is a drone? Most people imagine something flying, but to the Swedish innovation agency Vinnova, a drone can just as well be vehicle on or under water. SCOOT takes advantage of this wide definition to take part in Vinnova’s programme “Drones of the future”. SCOOT will demonstrate autonomous launch and recovery of the unmanned 60 kg Sailbuoy (Offshore Sensing AS) by the unmanned 500 kg SP SeaCat (SP Marine Tech).

The demonstration is part of Drone Center Sweden’s demo days on May 14th – 15th in Västervik, South-eastern Sweden. The SCOOT demo is part of the water session on the afternoon on the 14th. Even in the water session, we will be the only project demonstrating drones actually on the water… The project is a collaboration between University of Gothenburg, Research Institutes of Sweden Chalmers, University of Technology, Alkit Communications AB, SP Marine Tech AB, Depåservice AB.

“Robots giving YOU data from the ocean”

On May the 8th we open the SCOOT doors at Nya Varvet in Gothenburg, to anyone interested in the ocean, data from the ocean and methods for collecting ocean data. Come and meet the researchers and the robots! Most of all, come and tell us about your ideas: SCOOT wants to support your innovation. Read the full program. SCOOT open is part of #gbgtechweek and #EUinmyregion.

Mission completed: First Sailbuoy on the southern hemisphere

ASV, Sailbuoy, SB Kringla, Southern Ocean / May 23, 2019

On March 1st University of Gothenburg’s surface glider SB Kringla was successfully retrieved to the South African icebreaker SA Agulhas II. For 78 days she has relentlessly battled the waves in the Marginal Ice Zone along the Greenwich meridian, see graph below. SB Kringla is the first Offshore Sensíng Sailbuoy to be deployed and retrieved on the southern hemisphere. She has measured ocean surface temperature and salinity, together with surface wind, temperature and pressure in the atmosphere. Data from SB Kringla as well as from diving Seagliders can be viewed at ROAM-MIZ. Do you have ideas about surface gliders or diving gliders? Contact us.

Selected data output (Wind direction and latitude) from SB Kringla during the mission Dec 17, 2018 – March 1, 2019. Note the failing weather station on Feb 7.

We are suspecting that SB Kringla has encountered an iceberg during the mission. It is likely this happened on February 7 when the weather station started to fail. On retrieval we could see that the sensor head of weather station was cracked and that there were substantial damage to the sail. Amazingly she had continued, with no apparent effect on sailing performance!

SCOOT takes a dive in the Southern Ocean

ASV, Sailbuoy, SB Kringla, Seaglider, SG Semla, Southern Ocean / December 21, 2021

SCOOT director Sebastiaan Swart leads the major research project ROAM-MIZ, using sensors mounted on ocean robots/drones to investigate the marginal ice zone in the Southern Ocean. Information and near-real-time output from the sensors are available at the project website. The drones currently operating in the Southern Ocean include the diving (to 1000 m depth) Seaglider and the surface glider Sailbuoy, both available pro bono in the SCOOT offer to entrepreneurs, SMEs and researchers.
