Australia Chapter Antarctic and Southern Ocean Forum (ASOF)—
for Engineering Science and Technology
Reported by Mal Heron
ASOF was hosted by the OES Australia Chapter in Hobart, 14–17 August 2018. It was a single-track workshop co-sponsored inside IEEE by OES and GRSS, with CSIRO an external sponsor. Andreas Marouchos, who is Chair of the Polar Oceans OES Technology Committee, was the General Chair, ably assisted by Shona Lyden from CSIRO. Hobart is the smallest capital city, in Australia’s smallest state, with the biggest aggregation of oceanography and Antarctic science. Because Hobart is the supply base for Australia’s Antarctic activities, it has a large group of technology and engineering support personnel. The CSIRO research vessel RV Investigator was in port and the ice-breaker RSV Aurora Australis was preparing for the coming season in Antarctica. The ASOF program included a tour of the RV Investigator; but we did not manage to have the ice-breaker on the ice-breaker. The main signature of the Forum was the confluence of science and technology in the delegates and in the presentations. Perhaps it is the extreme conditions that people are working under in the Southern Ocean and the Antarctic Continent, or perhaps it is the close proximity of science and the supporting infrastructure in Hobart, but whatever the reason, the presentations in ASOF went all the way from lost moorings through to the highest aspirations for the planet. We heard about the science challenges as well as the issues in deploying and maintaining research instruments in this environment. Comment and discussions on presentations sometimes encroached on coffee break time. This came into focus when several feedback comments suggested that more time be allocated for structured discussion in future ASOFs. In the discussion at the end of the event there was a consensus that ASOF should be repeated in 2020, and the most significant take-home message was the success of the interactions between technologists, engineers and scientists. This was a most successful Forum in many respects.
Providence Chapter a Summary of the
Four Technical Meetings
Reported by Sandy Williams
James Michaelson, June 4, 2018
The first speaker was Dr. Jim Michaelson from Harvard Medical and Visiting Scientist at Woods Hole Oceanographic Institution. His topic was Micro CT Imaging, a technique most recently employed on clam shells and oceanic bird ears. The resolution of the CT scan is millimeters to microns, based upon a very intense and bright x-ray source. The application to surgery is where it has been most beneficial; permitting a surgeon removing a tumor to determine in minutes whether the excised material shows clean margins and if not the surgeon can extend the excision while the patient is still in the operating room, rather than returning a week later for a second procedure. Micro CT imaging was first employed in metallurgy but now has spread to other fields. The talk was presented at U. MASS. Dartmouth on June 4, 2018 at 6 PM. Because of the biological aspects of the subject it was advertised jointly with the Providence EMBS Chapter. The location between Woods Hole and Providence was convenient for all to attend.
Dr. Latha, June 25, 2018
On June 25, 2018, we had a guest from NIOT in Chennai, India—visiting Prof. Gopu Potty at URI. After Dr. Latha saw URI, she came with Gopu to Woods Hole Oceanographic Institution to speak with acousticians there and gave us a Chapter talk on Real Time Monitoring of Ocean Noise. The talk was very interesting. Dr. Latha started out by briefly summarizing the acoustics related activities her group at National Institute of Ocean Technology is involved in. This included
- Ambient noise measurements in shallow waters off the coast of India
- Noise measurements being carried out in the Arctic
- Geoacoustic inversion using ambient noise measurements made on Vertical Line Array in collaboration with URI.
- State of the art calibration facilities at NIOT in collaboration with NPL (UK), WTD (Germany) and VNIIFTRI (Russia).
- Humpback whale studies in shallow waters off Cochin, India in collaboration with WHOI.
The major topic covered in the talk was Real time monitoring of ocean ambient noise in Indian seas. She discussed the features of the autonomous passive acoustic measurement system with real time transmission, which has been developed for shallow water applications and operated in the open ocean at different sites off the Indian coast. The performance of the system in severe weather conditions, during multiple cyclones, was highlighted. Current efforts to develop a vector sensor array for passive noise monitoring were also discussed.
A lively discussion followed the talk on various topics covered in the talk especially related to the mooring design, telemetry aspects, and the marine mammal studies.
Milestone Event, September 6, 2018
On September 6, 2018 a Milestone event was held in Orleans, MA at the French Cable Station Museum. This was co-sponsored by the Providence Section and the Providence OES Chapter. Rene Garello, a principal speaker at the event, has already reported on it so it will not be commented upon here except to say it was a very interesting and rewarding event. The two sponsors each bought a bronze Milestone plaque, the OES plaque was in French, to copy one of the corresponding Milestone plaques in Brest, France at the other end of the 1889—1956 operating telegraph cable, first to connect Europe to the United States directly. Attendance was about 40 persons with about 10 IEEE members.
Mal Heron, September 7, 2018
Distinguished Lecturer, Mal Heron from Jamestown University in Queensland, Australia, gave the OES Providence Chapter a presentation on HF Radar in the Next Decade. He provided both background on the discovery and development of HF Radar as used for measuring ocean current remotely and the new ramifications of the use of Radar, even in the X-band, for surface current and waves. We benefited in his availability in Woods Hole, MA due to his position on OES ExCom, which held its late summer meeting on Cape Cod. This talk was on September 7, 2018 and was attended by 11 IEEE members and 3 Guests.

Onset Computing, Inc., September 27, 2018
In the interest of also representing manufacturing and industry in Chapter talks, a technical meeting was held on September 27, 2018 at Onset Computer, Inc. in the Bourne, MA factory. Jake Lacourse, Director of Hardware Engineering, and Jamie Pearce, VP of Marketing and Business Development, gave a series of presentations as well as a factory tour. Onset has a staff of 140 and all work, from product definition to assembly and shipping is done in this facility. It was a very interesting glimpse into an essential aspect of engineering. My personal interest in Onset arose from their data loggers, the Tattletale family, that I have used in my underwater instrumentation since their earliest days in about 1981.

Dr. Dajun Tang gave a talk on “Transmission Loss: a practical consideration” on the 28th of September. He is a Principal Senior Oceanographer at Applied Physics Laboratory, University of Washington. Dajun’s talk covered the definition, measurement, modeling, and application of underwater transmission loss through real data collected in some recently conducted experiments, and touched upon practicalities associated with predicting and measuring transmission loss. The talk was followed by an involved technical discussion along with a networking barbeque dinner held at the premises of the Acoustic Research Laboratory in the National University of Singapore.
In summary, we have had a range of talks focusing mainly on acoustics and marine robotics this year. We plan to round up this year with an annual year-end workshop complete with technical talks, mostly focusing around marine biology and bio-acoustics. We expect strong participation from students, industry and academia. The details of this event will be reported in a later BEACON article.
Seattle Chapter Technical Meetings
Reported by John Hager, Secretary, Seattle Chapter
USCGC Healy Tour
The monthly meeting for January, 2018, was a tour of the U.S. Coast Guard’s newest icebreaker, the USCGC Healy (WAGB-20), launched in 1997. At an overall length of 420 feet and beam of 82 feet the 16,000LT displacement ship can break 3-1/2 foot thick ice at a speed of 3 knots and ice up to 8 feet thick by backing and ramming. The vessel was designed to also conduct extensive science missions in the arctic. The ship features more than 4,200 square feet of scientific laboratory space, an array of oceanographic handling gear including multiple winches loaded with mechanical-optical cable, and a suite of sensor systems. The vessel can accommodate up to 50 scientists. The tour was conducted by two Ensigns, recent graduates of the U.S. Coast Guard Academy, each now with arctic cruise experience. These two ladies lead the group from the bridge, through the length of the ship, down to the engine level, providing a wealth of technical information at each station. The stations included not only the piloting, navigation, logistics, mechanical, electrical, and propulsion, but also the laboratory rooms and equipment, the high-bay hanger for research vans, equipment, and vehicles, and the gargantuan oceanographic winches (one loaded with 30,000 feet of mechanical-optical cable) on the lowest deck. Perhaps most impressive, beyond the deep knowledge of the ship’s specifications and capabilities, was the enthusiasm displayed by the two Ensigns. They regaled the group with stories of their physical training (damage control, fire-fighting, scuba diving), and their arctic cruise experiences piloting the ship through ice (and getting stuck, briefly), and supporting arctic oceanographic research. The education, training, experience, and eagerness which they displayed was impressive and inspirational.

Heave and Motion compensation
At the monthly meeting for February, 2018, Mr. Joseph Sabbia from Bosch Rexroth Corp. discussed “Calm Waters-Wait or Create? Active Heave and Motion Compensation.” The effects of wave motion can have significant safety and cost impacts on marine operations when handling heavy loads and sensitive oceanographic equipment. Maximizing up time can be achieved by using heave and motion compensating technologies which counter the wave actions. Active compensation solutions have been implemented in many aspects of marine operations from roll compensated helicopter landing platforms to deep water handling systems to 3 degree of freedom compensated platforms. Mr. Sabbia discussed his extensive work at Bosch Rexroth in the area of motion compensation where they have been able to deliver both hydraulic and electric driven compensation solutions from one to six degrees of freedom. He presented an overview of application examples for heave and motion compensated machines that Bosch Rexroth has delivered to the market and discussed the technology behind these systems including the differences between passive heave compensation and active heave compensation. Energy storage and recovery also was discussed along with state-of-the-art systems for multi-axis compensation.
Schmidt Ocean Institute’s ROV SuBastian
At the monthly meeting for March, 2018, Mr. Eric King from Schmidt Ocean Institute (SOI) discussed the rapid development and completion of the 4,000 m ROV SuBastian: “18 Months from Concept to Mission Ready.” In 2016 SOI added a pivotal ocean science resource to its suite of systems offered aboard the foundation’s 275 foot privately owned research vessel Falkor. SOI recognized the need for a dedicated remotely operated vehicle that could live aboard the ship. This vehicle, with some of the same capabilities as NSF’s ROV Jason and CSSF’s ROV ROPOS, would become a primary robotic tool available to scientists and researchers during collaborative expeditions. As a no-cost platform to the greater community of users, SOI is committed to continuously improve the vehicle’s specifications and enhance its plug-and-play features. Mr. King discussed how the project developed from concept to operational readiness, including the back story of SOI’s initial initiative to build an 11,000 m hybrid ROV. He also highlighted several recent missions where ROV SuBastian has been used off of Guam, the Republic of Kiribati, and the Kingdom of Tonga, along with upcoming 2018 projects off the Pacific Northwest coast in the vicinity of Hydrate Ridge. Of significance is the potential for low cost at-sea support of small oceanographic research projects through SOI. The Schmidt Ocean Institute is a 501(c)(3) private non-profit operating foundation established to advance oceanographic research, discovery, and knowledge, and catalyze sharing of information about the oceans.
