About Us


Luna Sea Solutions is committed to providing world-class STEM employment, including the ability to live and work in rural coastal communities.  We have infrastructure (office, equipment, and research vessels) in Lunenburg and Freeport, Nova Scotia needed to support ocean research, services, and technology development.



Greg Trowse - President & CEO


Greg is an oceanographer, professional engineer, and waterman with over 20 years experience including the most recent decade focused on assisting with development of the tidal energy industry in Nova Scotia.  He has assisted with deployment and recovery operations for the large OpenHydro turbines in the Minas Passage, but his focus and passion is on community-scale tidal energy initiatives in the outer Bay of Fundy (Grand Passage and Petit Passage). Greg is also a founding director of SOAR, a not-for-profit organization working to advance applied ocean research needed for responsible and sustainable development of ocean industries working with rural coastal communities.


Tristan Guest - Chief Scientific Officer

Dr. Tristan Guest is an oceanographer, data scientist, and programmer recently hired as the technical lead for Luna.

Tristan has degrees in Mathematics (B.Sc. 2013) and Physical Oceanography (Ph.D. 2020) from Dalhousie University.  He specializes in nearshore physical oceanographic processes and sediment dynamics, as well as software development for oceanographic applications.

Courtney Trowse - Community Collaboration Officer

Courtney is a visionary who helps chart the course, including specialization in working with rural coastal communities and collaborative research projects.

Richard Cheel - Chief Technology Officer

Richard Cheel is a physical oceanographer with almost 20 years of experience in oceanographic science and technology. Richard has done field work in a variety of marine environments, from open ocean to tidal environments and dynamic beaches. He has designed and implemented high-level research programs and deployed a large variety of oceanographic instrumentation including ADCPs, hydrophones, USV/UAVs, multibeams, and prototype research instrumentation. In addition, Richard has extensive experience in the design and implementation of laboratory based acoustic measurements in conjunction with academic and industry partners.

Richard is interested in new oceanographic technologies and in novel uses of existing technologies in support of ocean science. He has also never gotten sea sick.


Allie Flower - Mate & Content Specialist

Now a full fledged ocean fanatic, Allie fell in love with the ocean at a young age while working with her father's whale watching company. She pursued her passion for science at St.FX where she completed a Bachelor of Science while leading the Varsity Track Team. After graduation, Allie was a part of a 4-man crew in 2019-20 that sailed to the Bahamas from Nova Scotia on a four month voyage. She has since spent most of her time on the water which has pushed her to pursue more education in the marine environment and has earned her SVOP* and STCW Basic Safety* in 2020-21, while working as a deck hand lobster fishing on the Nellie Row! Allie is thrilled to join the team to help get the LunaOcean’s App on the map.

SVOP* - (Small vessel operator proficiency) STCW Basic Safety* - (Standards of Training and Certification in Watchkeeping and Marine Emergency Duties)

Justine McMillan - Ocean Scientist

Justine is a physical oceanographer, specializing in the measurement and analysis of tidal flows and oceanic turbulence. She earned her Ph.D in Physical Oceanography from Dalhousie University in 2017 and has worked in the ocean technology industry since then.

Justine is working with Luna to help develop software to process ADCP data, including initial data handling through to advice on computation of key turbulence metrics.

Lauchlan Chisholm - Software Engineer

Lauchlan is a musician, and programmer who strives to enjoy his life, and spread that joy to others. As a software developer he is experienced in the agile approach to SDLCs from discovery to deployment.  An entrepreneurial orientation has led him to focus heavily on positive relationships and results-driven activity.  Recent interests have focused on integrating and aligning DevOps best practices to every project he is a part of.

Research Vessels

Luna Sea Solutions owns and operates two oceanographic research vessels used to help advance ocean technology development and research projects.

The Grand Adventure

The Grand Adventure is a Rosborough 28 with:

  • John Deere inboard diesel main propulsion
  • Stern platform with auxiliary engine mount (15 hp Evinrude), swim ladder, and ability to deploy and recover equipment from near water surface
  • Boom with hydraulic winch and davit/block with hydraulic lobster hauler
  • Extended wheel house with work station and dedicated clean power supply for ocean electronics.
  • Navigation system, sounder, radar, and all Transport Canada required safety systems.

The (mighty) Puffin

The Puffin is fast and maneuverable a Rosborough 18 (RF-18) ideally suited to working in fast flowing waters, with:

  • 90 hp Yamaha outboard main propulsion
  • 9.9 hp Yamaha auxiliary propulsion
  • Pole mount, tow bollard, and hand winch
  • Dry space and dedicated clean power system for ocean electronics in the cuddy space
  • Navigation system, sounder, and all Transport Canada required safety systems.
