Mission completed: First Sailbuoy on the southern hemisphere

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!

AUV Ran in the headlines

If you are first to go under the under Antarctic ”doomsday glacier” (and making it back!), you will get headlines. SCOOT’s flag robot, AUV Ran, together with professor Anna Wåhlin and her team feature both in rock ‘n’ roll magazine Rolling Stone and in a radio show from PRI’s The World. Links:

As always, SCOOT wants to put hardware and data in the hands of people with ideas. Interested in AUV Ran? Please contact us. She will be back from Southern Ocean in time for hands on workshop 17 – 20 June on Bornö at the west coast of Sweden.

First voyage under Antarctic ”doomsday glacier”

What an achievement! Professor and Scoot board member Anna Wåhlin (bottom left in photo) tweets: “OMG we did it – we went under Thwaites ice shelf!! We have water samples, bathymetry and ocean physics from underneath the 300-500 M thick ”doomsday glacier”. The Swedish AUV Ran was first. So so proud of our team!!” More about this on GU web.

Now the really interesting part. If you are an entrepreneur, innovator or researcher with ideas about measurements in the ocean or data from the ocean, Scoot makes the AUV Ran available for YOU. Interested? 1) Contact us, 2) meet us at Scoot open house, 8 May at Nya Varvet in Gothenburg, 3) join us for a hands on workshop at the classic oceanographic station on Bornö in the Gullmarn fjord, 17 – 20 June.

SCOOT takes a dive in the Southern Ocean

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.
