The 12th Underwater Technology Forum・ZERO
HYBRID
Reported by Harumi Sugimatsu
The 12th Underwater Technology Forum・ZERO was held from 13:00-17:00 on 11 October 2024, on the Atmosphere and Ocean Research Institute, The University of Tokyo in Kashiwa Campus (https://www.aori.u-tokyo.ac.jp/english/access/index.html). This time, we had 66 in-person attendees and 142 online attendees.
The highlight of the forum was a live reporting from the Deep Earth Exploration Vessel “Chikyu” on its 405th research drilling cruise (JTRACK: https://www.jamstec.go.jp/chikyu/e/exp405/). For the audience, the researchers aboard the vessel were given a virtual tour of the core laboratory and other facilities where drilled core samples are analyzed. In the venue, Asuka Yamaguchi (Forum co-organizer) explained the significance and purpose of the drilling survey and core sampling. It was a time when the audience and the researchers on board became one.
The following lectures (Science in the first half, Engineering in the second half) were then given.
- Recent changes in tropical Pacific SST (sea surface temperature) patterns are a mystery
- What happened in the sea during the Noto Peninsula Earthquake? Results of shallow-sea bottom survey along the Coast of Suzu-shi and Noto-cho
- Advances in Marine Microplastics Research
- Introduction of HUGIN Endurance for two-week continuous operation
- Realization of a Fishing Robot Boat by a University Startup
- Development of monitoring systems for sustainable ocean use
- Where the Seabed 2030 Program is now? Working in Monaco, Living in South France – Online talk from Monaco
From the talk “What happened in the sea during the Noto Peninsula Earthquake? Results of shallow-sea bottom survey along the Coast of Suzu-shi and Noto-cho”
In the last talk, it is presented that Seabed 2030, which aims to acquire 100% of the world seafloor bathymetry by 2030, had acquired about 6% at the start of 2017 and 26.1% as of 2024. This is a fourfold increase from the beginning, but 70% still remains unknown. This shows the difficulty of acquiring data on the seafloor.
The next 13th Forum will be held on the 11th of April, 2025, at the Institute of Industrial Science, the University of Tokyo. See you there!



Australian Council Chapter
Building Momentum and OES Special Session at IGARSS 2025
Reported by Melanie Olsen, Chapter Chair

The Australian Council OES Chapter continues to build momentum through facilitating technical talks across Australia for our members. We welcomed a technical seminar by Craig Steinberg on mass coral bleaching weather and oceanography and engaged with national marine science agencies AIMS and CSIRO to share joint monthly technical seminars.
In September, we organised our first OES Distinguished Lecturer series virtual technical seminar, which was well attended and a resounding success. Dr. Kenneth G. Foote from WHOI spoke to ocean technologists across Australia and New Zealand regarding making defensible active-sonar measurements of pelagic fish abundance. We are grateful for the OES Distinguished Lecturer program for this opportunity.
Our OES Chapter will be hosting a special session on the Challenges for Ocean Remote Sensing in the UN Decade of Ocean Science for Sustainable Development at IEEE International Geoscience and Remote Sensing Symposium (IGARSS 2025), which will be held in Brisbane Australia on the 3-8th of August 2025. This is a great opportunity to share your research and build connections with Australian OES members and the IEEE Geoscience and Remote Sensing Society. The paper submission portal is now open. https://2025.ieeeigarss.org/Papers/Submission.asp?SessionType=CCS&ID=2029
To lodge papers at our session, select our topic from the dropdown menu at the “Primary Session Topic – Subtopic prompt.” It would be great to facilitate sharing your research with like minded peers in Brisbane next year.

Victoria Chapter
OES Victoria Chapter tours Open Ocean Robotics facility

Reported by Nick Hall-Patch, Secretary – Treasurer
In the September 2020 OES Beacon (https://ieeeoes.org/oes-beacon/september-2020-oes-beacon/open-ocean-robotics-asv-winch-university-of-victoria-student-capstone-project/), Ryan Foxall wrote about a University of Victoria student capstone project sponsored by The OES Victoria Chapter. That project involved the design of an automated winch that the students had developed for a local engineering firm, Open Ocean Robotics, to be mounted to one of their robotic surface vehicles. Four years later, Chapter members and guests were able to tour that company’s facility with Dr. Fritz Stahr, its Chief Technical Officer, as our host.
The tour started at Open Ocean Robotics’ entrance, where we obtained some historical background about the company, and its specialty: uncrewed surface vehicles (USVs). Julie Angus, the first woman to row across the Atlantic Ocean from mainland to mainland, is the co-founder of the company and its CEO; the idea for building uncrewed surface vessels (USV) for ocean monitoring was developed after observing extreme storm conditions during that rowing expedition. Also at this point, we were able to view earlier versions of USVs that the company had developed as well as Open Ocean Robotics’ present USV, the DataXplorerÔ.
The USVs are about four meters long, and are light enough to be deployed on a wheeled cart by one or two people. They generate little sound while in operation, using electrical propulsion, powered by lithium-ion batteries that can be recharged with solar panels mounted on the deck. The autonomous recharging capability means that deployment for months at a time is possible. The USV’s are fitted with cameras looking all around, as well as various sensors, both above and below the waterline, for basic environmental data.

A unique feature of their design is the minimal keel beyond the protective housing for the propellor, which means that they can be used in very shallow water. Self-righting in turbulent seas is provided instead by a buoyant roll bar mounted above the stern of the vessel, as seen in the accompanying Figure.
A video clarified further some of the DataXplorer details, not to mention showing us spectacular examples of the self-righting capability in the surf zone off western Vancouver Island. (This can also be seen in a video clip on the company website https://www.openoceanrobotics.com/surface-vehicles). An important component of the USV is its software, XplorerView™ Mission Control, and we were shown examples of the software in action. Although the DataXplorer can be run unattended, users can also control the USV at all times, using video and other data streamed back from the device. We were told that a trained single user could control three, and perhaps more, USV’s at once using the software.
A very recent example of a USV deployment in Shinnecock Bay with Stony Brook University was also described in the video, outlining the advantages of USV deployment for water sampling for eDNA compared with more traditional methods. These included being able to sample in shallow sites, to sample at night, and perform more frequent sampling at well defined sites than a crewed surface vessel could do.
The tour concluded in the company assembly area where we were able to look over the facilities, examine the inner workings of USV’s being assembled, and were able to discuss sensor possibilities and placement.
