Catching up with Jonathan Colby, our 2025 Lennard-Senior Memorial Prize Winner

Awarded at All-Energy for his impact in marine renewables, Jonathan reflects on his journey—from leading the USA’s first licensed tidal project to growing with SUT’s Marine Renewable Energies Committee (MREC).

We caught up with Jonathan to find out more about his journey in the marine renewable energy sector.

🔹 What first sparked your interest in marine renewable energy?

I was already working in the power sector, and I had a background in experimental fluid mechanics, when I discovered marine energy.  Utilising the incredible power that is clearly present in crashing waves and rushing rivers and tides resonated with me immediately.  Further, the predictability of the tides struck me as an incredible asset of tidal energy in particular.

🔹 You were instrumental in the success of Verdant Power’s Roosevelt Island Tidal Energy (RITE) Project – the first commercially licensed tidal power project in the USA. What stands out most when you reflect on that experience?

Overall, the experiences we shared, and accomplishments we made, as a team at the RITE Project over the 15+ years I was there are the things that stand out to me. 

Some are technical, from the total number of MWh delivered to the NYC grid to the issuance of the first ever IECRE Test Report for Marine Energy; others are logistical, from temporarily closing the East Channel of the East River for deployment, maintenance and retrieval operations to barge journeys across the New York City harbour; while others are experiential, from forging strong relationships with the local community and the range of stakeholders involved to the quietness of slack tide at night.

🔹 You’re an active member of SUT’s Marine Renewable Energy Committee (MREC). What role has that community played in your professional journey—and why do you think groups like MREC are important for the sector?

MREC has played a very important role in my journey.  It has enabled me to stay closely connected to the Marine Energy industry in the UK, enhanced my technical knowledge in a broad range of aspects across the sector, and it has helped my professional (and friendship) network grow. 

Groups like MREC are critical for the sector as they facilitate informaEnergy andge across many technical, economic, regulatory and political topics, among others, which can highlight best practices from within (and outside) of Marine Energy, and can help to identify critical gaps in the industry.  

🔹 What does receiving the Lennard-Senior Memorial Award mean to you?

It is a tremendous honour for me to receive the Lennard-Senior Memorial Award.  True luminaries in the Marine Energy industry have won this award and similarly, true luminaries were nominated alongside me. 

To be recognized by my peers for my contributions to Marine Energy is humbling, however, the amazing people I have worked with over the nearly 20 years in Marine Energy have enabled and supported my career.  

I am grateful to all the colleagues I have worked with, and friends I have made, across the world.

🔹 What advice would you give to the next generation of marine energy professionals?

Work hard, have fun, and never give up!  As in any job but particularly working in the smaller companies generally found within Marine Energy, it is critical for the next generation of professionals to be accountable, independent thinkers and dedicated to delivering high quality work in a timely manner. 

For the industry to succeed, we need to see more and more successful deployments of devices in the water, operating for years – this simultaneously requires a long-term, broad vision and a sharp focused attention to detail in the daily execution. 

As one piece of proper advice, based on my experience: a postgraduate degree can be an incredibly beneficial experience to prepare professionals for work in this sector. 

Congratulations Jonathan and thank you for sharing!

The Society for Underwater Technology (SUT) and the Marine Technology Society (MTS) are pleased to announce that nominations are now being accepted for the 2025 Captain Don Walsh Award for Ocean Exploration.

Awarded jointly by the two Societies, this award recognises outstanding, sustained, international contribution to the development, application, and propagation of marine technology toward the advancement of ocean exploration. Nominations will be accepted until May 31, 2025.

The presentation to the 2025 winner(s) of the Captain Don Walsh Award for Ocean Exploration will take place at Oceanology International in London on March 10th 2026.

Don Walsh (1931-2023) was an American oceanographer, explorer, retired naval officer, and marine policy specialist. He and Jacques Piccard were aboard the bathyscaphe Trieste when it made a record descent into the Mariana Trench on January 23, 1960, the deepest point of the world’s oceans.

Nominations have now closed.

The judging panel, comprised of the presidents and three members from each society, will reflect diversity in demographics, sector and discipline.

Past winners

In 2020 the inaugural award was made to Dr. Edie Widder, MacArthur Fellow, a deep-sea explorer, and conservationist known for her expertise in oceanographic research and technological innovation and her commitment to reversing the worldwide trend of marine ecosystem degradation.

2021 saw it won jointly by Victor L Vescovo and Patrick Lahey for the 2019 Five Deeps Expedition and further dives of scientific or historical interest in subsequent years, described by a distinguished member of The Explorer’s Club as “The most ambitious exploration expedition of the century”.

The 2022 award was won by internationally recognised oceanographer Dr Samantha (Mandy) Joye a Professor in the Department of Marine Sciences at the University of Georgia, USA whose work has revealed unexpected connectivity between elemental cycles, unanticipated feedbacks between geological elemental and microbial dynamics, and fundamental controls on microbial populations and their activity. Her work accomplished during studies of the environmental response to the Deepwater Gulf of Mexico oil spill, led to the discovery of deepwater oil plumes, hydrocarbon rich layers in the water column that were neutrally buoyant above the seafloor but well below the surface.

Then in 2023 Dr Peter Girguis, Professor of Organismic and Evolutionary Biology at Harvard University and Adjunct Oceanographer at Woods Hole Oceanographic Institution, described by his peers as ‘the epitome of a deep-sea explorer’ and ‘a man for all ocean seasons, was the winner whose career has been dedicated to increasing understanding of the animals and microbes that thrive in the deep sea.

Last year it was Martin “Marty” Klein, a name synonymous with ocean exploration, and a true pioneer in the field of underwater technology. who was declared the winner. Known as the “father of side-scan sonar,” Marty’s innovations have revolutionized oceanographic surveys and underwater searches.
