AUV

Small companies using big robot

She is a mighty beast, SCOOT’s flagrobot AUV Ran: 7 meters long, weighing around 2 tonnes and with a sensor suite like a modern research vessel. In 2019 we demonstrated Ran to a number of SMEs, and in 2020 the startup company Marflow AB got a dedicated day of Ran operation. In March 2021 the turn came to three other small companies to operate and get data acquisition done by AUV Ran: SeAnalytics AB, Ten Island Seafarm AB and Bottenlusen / Vinga Konstruktion AB.

There are more SCOOT days in Ran’s calendar this year, in June and in August/September. Do you want to join? Click the buttons below.

"Our start-up has been a fantastic success, and now we want to grow. Through the support of SCOOT and the surveying done by AUV Ran we are well prepared for expanding our installations at sea. And it was great to work with Stephan Hagerling at Bottenlusen."
"The mapping done by AUV Ran was impressive: The details, the speed, the complete coverage of the area I wanted. I cannot see how I could have got this data in any other way. Through SCOOT I have also started an interesting collaboration with Ten Island Seafarm AB."
"The possibility of using AUV Ran for automated sampling of water in the monitoring of invasive species based on eDNA analysis is very important for us. It is a cost-effective way of covering a large area. Such an 'early warning' system is essential to mitigate invasive species."

Mission & data acquisition

Breaking: Ocean Infinity acquires SCOOT partner MMT

Yesterday came the news that our partner MMT is being acquired by another major within ocean surveying: Ocean Initity, the pioneer in the use of simultaneously deploying fleets of marine robots. At SCOOT we are excited about the possibilities for synergies!

"I’m glad we have found new owner who want to develop MMT in the future and who also has a lot of interesting technology for us to explore. This will not change our engagement in SCOOT or other arrangements we have, e.g. with the University."
P-O Sverlinger
CEO, MMT

Ocean Infinity today operates a large fleet of AUVs, similar to our flagrobot AUV Ran (owned by UGOT, mananged by MMT). Ocean Infinity’s Armada Fleet represents a coming leap in the use of surface-going ocean robots.

Do we need to say that there has been many comments and ‘Wow!’ on Twitter and LinkedIn and other fora… Here is the press release on the matter (pdf):

AUV Ran back in Sweden: Join the collaboration, tests and operations in 2021!

In 2019 SCOOT’s flagrobot AUV Ran became first to conquer the depths under the ‘doomsday’ Thwaites Glacier. In 2020 Ran’s greatest achievement was the mapping of subsea landslides in the 2000 metres deep Kaikōura Canyon off New Zeeland (read news at NIWA and see their nice Ran pop video below!).

Now Ran is back in Sweden, and as always SCOOT makes her available for entrepreneurs, innovators and SMEs. First out is a group of SMEs during an intense mission week in early February on the Swedish west coast.

Let us know if you want to join the collaboration/testing/operations, already in February and in the planned June session. We are not looking for AUV experts only. We are looking for anyone with ideas for utilising or collecting ocean data!

Ocean Data conference spurs collaboration!

September 29th at Nya Varvet and online

What a day… The conference Ocean Data for Ocean Health covered a lot of the themes SCOOT has been involved in the last two years. We hosted the event on September 29th at SCOOT’s space at Nya Varvet in Gothenburg, and we were happy to gather quite a number of old and new SCOOT people and partners.

The programme scratched on the surface of many urgent topics. SCOOT is committed to contribute to keeping up the momentum of this dynamic environment! (Just hosted breakfast meeting on sensors platforms of opportunity, see below.)

Especially intense for SCOOT was the final Block 4, demonstrating autonomous technology for collecting ocean data, see below.

October 21st, breakfast webinar on tuna and fishing vessels

We were 6 persons having our morning coffee at Nya Varvet and another 6 joining the video meeting. Picking up from Sept 29th, we talked at some length about opportunities (and challenges) around data from tagged animals and from sensors mounted on fishing gear/vessels. Take home messages:

  • These data have huge potential to fill serious gaps in existing ocean monitoring programmes, where other and autonomous methods struggle. These gaps include shelf and coastal seas and marginal ice zones.
  • The cost-benefit relation is very good!
  • The infrastructure for collecting and distributing these data is rapidly expanding and maturing.
  • Challenges include subsurface communication and integration into existing monitoring data flows.

Recording from the meeting.

SCOOT’s flagrobot AUV Ran investigates the effect of subsea earthquake

This is really AUV Ran doing her thing: Deep under, manoeuvring close to the bottom, using her vast sensor suit to scan the environment. This time it is for the benefit of researchers in New Zeeland, investigating the seabed of the 2000 metres deep Kaikōura Canyon. It was transformed by an earthquake in 2016; 850 million tonnes of sediment were displaced!

We expect Ran to be back in Sweden in January. Every once in a while she takes a rest behind SCOOT’s office/workshop at Nya Varvet in Gothenburg. Please contact us if you want use AUV Ran or if you just want to take look. We plan 10 operational SCOOT days for Ran in 2021.

AUV Ran cooperates with start-up company Marflow AB

SCOOT’s flagrobot AUV Ran is one busy two-tonne-piece of equipment. From the Southern Ocean to the Baltic Sea, and later this year off to New Zeeland. However, last month a window of availability opened… Startup company Marflow AB with founders Erik Nordborg and Glenn Hederot jumped on this opportunity.

Erik explains:

“Marflow aims to investigate and map ocean currents with very high accuracy. Precise measurements of the oceanic conditions in both time and space are valuable to us but indeed difficult to achieve in reality. AUV Ran will however allow us to do just that, studying ocean currents along with numerous other parameters with a spatial coverage that we have not been able to do before.”

“Marflow are very excited and happy for this opportunity to try AUV Ran and to discover what we can actually achieve with a tool like this. Before launching, Anna Wåhlin helped us setting up a course for Ran to follow. It was really impressive seeing AUV Ran navigating so accurately along this predefined route in relatively confined waters –all the time logging valuable data.”

Ocean robots: Expanding fleet and expanding competence pool

A new player has joined the ocean science community in Sweden: VOTO – Voice Of The Ocean. SCOOT is of course delighted that VOTO is a strong believer in automated methods of observations. VOTO has already a fleet of six ocean robots: 4 diving SeaExplorers by Alsemar and 2 surface going Sailbuoys by Offshore Sensing. SCOOT’s director Seb Swart and his team joined VOTO’s SeaExplorer course, read their report!

We will definitely hear more about VOTO and their ocean robots and the data they gather… 

ROAM-MIZ successfully deploys a fleet of autonomous technology to observe small-scale processes in the Antarctic sea ice

Louise Biddle summarizes the Austral winter-spring season for this robotics heavy project:

The ROAM-MIZ (Robotic Observations And Modelling in the Marginal Ice Zone) project aims to capture high resolution observations of how the upper ocean near and under sea ice responds to sea ice growth or melt. The team, led by SCOOT’s director Sebastiaan Swart at the University of Gothenburg, deployed multiple platforms in, and at the edge of, the marginal ice zone in austral winter and spring 2019. Using the South African icebreaker, the SA Agulhas II, as a deployment platform, three profiling ocean gliders (Seagliders), a surface glider (Offshore Sensing Sailbuoy), multiple wave-recording surface floats (SWIFT buoys) and two ice-moored buoys were deployed between 56-60°S. Between the 10 platforms, over 370 days of data were collected from this remote and under-sampled region of the Southern Ocean, with the longest continuous time-series of over 130 days.

The challenges that the deployment team and platforms faced included rapid freezing up of sensors in temperatures that dropped to minus 20°C (before wind chill), rough seas and rapid movement of sea ice floes. With support from collaborators around the world including CSIR (South Africa), CalTech (USA) and University of East Anglia (UK), this project has demonstrated that autonomous instrumentation holds the capability to explore and monitor some of the most inaccessible oceans on Earth. Data is now being processed by the team based at the University of Gothenburg, with the “live data” viewable on roammiz.com and the first paper recently published in Geophysical Research Letters. Projects update can be followed on @PolarGliders .

National Research & Innovation Agenda for Underwater Technology

SCOOT is active in SubTechSweden, a network of actors who want to strengthen innovation in underwater technology in Sweden. SubTechSweden now releases NRIA-U 2019 (National Research & Innovation Agenda for Underwater Technology). The agenda has a very clear main recommendation: Sweden needs “a joint programme for underwater technology, funding and coordinating basic research, applied research and demonstrations (TRL 1 – 6)”. NRIA-U 2019 is an updated version of NRIA-U 2016.

SubTechSweden emphasises that the underwater innovation area can help to meet the UN sustainability goals, the Government’s Maritime Strategy and Sweden’s underwater capability (decided by the Government to be a “significant national security interest”). NRIA-U 2019 mentions specifically the need for underwater technology in ocean science, monitoring, spatial planning and management. The achievements of SCOOT’s flagrobot AUV Ran under the Antarctic ice shelves are mentioned as a good example of innovation, together with platforms for infrastructure inspection, illustrated with MMT’s Surveyor Interceptor.
