An Afternoon of Sailing, August 3, 2019
The Liberté is a magnificent 3-masted schooner which plies the beautiful waters of Cape Cod and the Chesapeake Bay. During the summer it ties up at the Clam Shack, just inside the mouth of the harbor in Falmouth, MA. The vessel has a length of 74 feet overall (65 feet on deck), with a beam of 18.5 feet. This staysail schooner carries 1700 sq.ft. of sail, spread over six sails and can cruise under diesel power at 8.5 knots.
The IEEE Providence Section, in cooperation with the OES Chapter, chartered the Liberté for a 3-hr afternoon sail. The plan was to sail within the general area of Nantucket and Vineyard Sounds, but the course taken is decided by the captain and depends on the wind and tides encountered on the day of the event. In 2018 our cruise was cancelled at the discretion of the captain because of foul weather. This year the sea state was moderate and winds were brisk from the southwest. From Falmouth we sailed south across to Martha’s Vineyard and viewed the harbors of Vineyard Haven and Oaks Bluff from the sea. There was ample time on board for conversation with old and new friends from the OE chapter and the broader Providence section. A total of 17 IEEE members and 21 guests were on board. All hands were accounted for when we tied up back in Falmouth.
Dr. Chris Chapman, August 19, 2019
Large, underwater earthquakes generate many types of waves – elastic P and S body waves, surface Rayleigh and Love waves or normal modes, acoustic waves in the ocean (T phase) and ocean gravity waves (tsunami). The latter are often the most devastating and cause the greatest loss of life. On Boxing Day, December 26, 2004, a magnitude (Mw) 9.1-9.3 megathrust earthquake occurred with an epicenter off the west coast of northern Sumatra, Indonesia. It was the third-largest earthquake in recorded history, lasted 9 minutes, and released as much strain energy as all other earthquakes combined over the previous 15 years. The associated tsunami propagated across the Indian Ocean where communities surrounding its coasts were greatly affected. Major disruptions occurred in Indonesia, Sri Lanka, India and Thailand. The tsunami killed an estimated 227,898 people in 14 countries. At the time of the earthquake Chris Chapman was vacationing with his wife on the coast of Sri Lanka.
Chris Chapman is the Emeritus Honorary Professor of Theoretical Seismology at the University of Cambridge, UK. He has held academic positions at the University of Alberta, the University of Toronto and Cambridge University. He has conducted research at Scripps Institution of Oceanography and has worked as a Scientific Advisor for Schlumberger Cambridge Research. He is the author of the textbook “Fundamentals of Seismic Wave Propagation” (CUP, 2004). Our OES chapter hosted Professor Chapman at the University of Massachusetts, Dartmouth, to hear his presentation on the physics of waves from an underwater earthquake and his personal experiences of the tsunami from the Boxing Day 2004 Sumatra earthquake. Professor Chapman presented data from all the types of waves emanating from this event. He described the basic physical features of the excitation and propagation of the tsunami together with the properties that made this tsunami so devastating, and he explained how the other waves can be used to issue tsunami warnings. Professor Chapman was kind enough to break away from his New England sailing vacation to make this presentation, which was attended by 7 IEEE members and 11 guests.
Dr. Rupp Carriveau, October 16, 2019
The Wind Engineering, Energy and Environment Research Institute (WindEEE RI) was established in 2011 in order to pursue novel opportunities in wind research at Western University, Canada, related to the emergence of the world’s first three-dimensional testing chamber, the WindEEE Dome. The Institute has promoted innovative research and extensive collaborations nationally and internationally. The areas of research at WindEEE target the three EEE’s: wind Engineering, Energy and Environment. Main topics of research relate to: impact of non-synoptic wind systems (such as tornadoes and downbursts) on buildings and structures, optimization of wind farms and wind turbines, physical modelling of flow over rough surfaces, urban canopies, complex topography and forestry, outdoor and indoor air quality, and wind driven rain and snow.
Dr. Rupp Carriveau is the Director of the Environmental Energy Institute and a Director of the Turbulence and Energy Lab at the University of Windsor in Ontario Canada. He is Chair of the IEEE Ocean Energy Technology Committee. His research activities focus on energy systems futures, and include collaborative research that makes use of the WindEEE facility.
Multipurpose floating platforms are now being considered for renewable offshore energy generation, energy storage, desalination, agriculture, aquaculture, and habitation. While lessons can be learned from the oil and gas industry, design constraints of these platforms make direct comparison difficult. A generic model offshore platform is currently being tested in WindEEE; a unique hexagonally domed facility capable of producing scaled tornadic, downburst, and highly sheared wind profiles. In his presentation, Dr. Carriveau discussed observations from early analysis of the data and challenges encountered during scaling, measurement, and mooring of the experiment. Initial results indicate that the extreme wind cases of tornado and downburst produced very significant motion for the platform. The lecture at WHOI was attended by 6 IEEE members and 3 guests. Coincidently, and as if to further demonstrate the relevance of wind research, Cape Cod was struck by a “Bomb Cyclone” late on the evening of this meeting, as atmospheric pressure fell by 43 millibars within 24 hours. There was widespread flooding, downed trees and power outages.

Student Marine Technology Spring Mixer
In May, the University of Washington’s Ocean Technology class students requested members of the OES and MTS local chapters to provide review and comment on the students’ year-long projects. After the presentations, the students provided a pot-luck dinner and a networking mixer. This has become an annual event since the Ocean Tech class began a couple of years ago. Students are required to build and document a simple sensor that gets deployed in the water, and an evaluation of its merits is presented to the invited professionals. The sensors range from simple temperature/conductivity cells, to acoustic tracking, and to optical AUV docking systems and software. Input from the professionals has made for an evolutionary sophistication of the individual projects as well as networking contacts for jobs and graduate direction.

OES Seattle Section Support for OCEANS Conference
The main thrust of the chapter members for the bulk of the year has been participation in the preparation and execution of the OCEANS 2019 conference held in Seattle on 27-31 October. Member participation ranged from the Local Organizing Committee (which had meetings starting at once per month in January to weekly intervals for the 6 weeks prior to the conference) and its various subcommittees, serving to review posters and papers, and a variety of volunteer activities during the conference. This level of tasking left little time for the regular chapter meetings – indeed we had to decline an offer of a talk by a Distinguished Lecturer due to overloaded schedules. An offshoot of conference participation was new linkages with other, somewhat geographically close, chapters to look at future joint meetings and collaboration. Work with chapters in Portland, Oregon and Vancouver, British Columbia has been done in the past for other related societies, e.g., Acoustical Society of America local chapters.

Talk on Auditory and Behavioral effects of noise in marine mammals
Reported by Mae Seto and Christopher Whitt
On April 30, 2019, the Chapter organized a talk and networking event with world-renowned researcher Dr. Brendon Southall on Auditory and Behavioral effects of noise in marine mammals. Marine mammals use sound for many critical life functions. Human sound in their environment can interfere with communications, affect their hearing, influence behavior and cause non-auditory physiological effects. Recent work on both auditory and behavioral effects of noise was presented. As well, Dr. Southall discussed how the results from this work is integrated into defining noise exposure criteria and applied in regulatory decision-making and mitigation of noise impact on marine mammals.
The talk was hosted by the Centre for Ocean Ventures and Entrepreneurship (COVE) in Dartmouth, Nova Scotia, Canada, and attend by around 50 people.
Talk on Passive Acoustics for Ocean Observations
Reported by Mae Seto and Christopher Whitt
On October 15, 2019, Christopher Whitt gave a talk on Passive Acoustics for Ocean Observations, sponsored by the Chapter and in coordination with the Dalhousie University Oceanography Department’s Seminar Series. Passive acoustic monitoring is a powerful tool to study the ocean with. Long-term underwater acoustic recordings capture the distribution of human activity and marine life and provide insight into changes in physical oceanography. Directed measurements help to understand the impact of activities ranging from geophysical surveys, shipping traffic to marine construction. Several recent projects were discussed as case studies to showcase the state-of-the-art. The talk was attended by about 40 people, including Chapter members, graduate students and several guests.
