Terry has served as both technical director and sales and marketing director of some of the industry’s best known companies and formed Planet Ocean Ltd in 2003.


Iain is a founder member of the Society of Maritime Industries, Marine Autonomous Systems Group and leads our ecoSUB AUV team.
Iain, is a trustee of a charity based in West Africa delivering water solutions to rural communities and enjoys outdoor pursuits especially diving, surfing and running.

Outside of Planet Ocean, Danny is very active in her community and has been a school governor for 7 years, is a Trustee and Treasurer for a local charity and also provides French tuition, both private and also taking classes for a local junior school and nursery. Danny enjoys running and keeping fit. She spends an excessive amount of her spare time entering obstacles/mud races. She also has a handbag and shoe addiction!

Formally, an accomplished footballer, he is no longer Premier League standard and has taken up CrossFit in a big way, and competes to stay in shape. Happiest at Glastonbury with a warm cider in hand.

Leif is a graduate of the University of Oslo, Norway & Narvik University College and has served in the Andenes Airforce.
Out of the office, Leif loves the outdoors and spending time with family on his boat, or biking, kayaking and swimming. He is fluent in English, Norwegian, with a working knowledge of Spanish and Japanese.

Jonathan graduated with a first class MSc in Robotics & Computation from UCL where he specialised in machine & deep learning in vision navigation for SLAM which followed on from his first class honours degree also from UCL in electronics, robotics and control systems.
In his spare time Jonathan is a keen fencer and climber.

Outside of work, I mostly spend time playing with my two young sons.
I also enjoy watching some Japanese anime, especially Frieren: Beyond Journey's End and Hunter × Hunter. I used to keep goldfish and enjoy small aquariums back in Japan.



Certified in PRINCE2 project management, Naomi brings a hands-on, solutions-focused approach to every project. She thrives on close collaboration with end users, especially during deployment and field testing. In 2016, she co-developed the original ecoSUB AUVs at the National Oceanography Centre, and was excited to re-join the team in Summer 2025.
Outside of work, Naomi enjoys surfing, exploring the outdoors and adventuring in her camper van.

Jordan joined the ecoSUB team in Summer 2025 and rapidly grew into his role, taking on significant responsibility for much of the financial administration, but also supporting the team in the Petersfield manufacturing site.
Outside of work Jordan is a big sports fan, following his favourite football team, PSG and American football team, the Packers, as well as being a big fan of F1. Jordan enjoys a round of golf, although he's apparently no Nick Faldo. Travel is also another passion, having recently spent nine months living and working in Australia.
Planet Ocean supports Seabed 2030
We are extremely proud to be supporting the Nippon Foundation’s Seabed 2030 Initiative, which aims to map 100% of the ocean floor by 2030. This is a huge challenge, and we are delighted to be playing a small part in this ambitions project.
The Nippon Foundation-GEBCO Seabed 2030 Project has entered into a memorandum of understanding with ecoSUB Robotics – a division of Planet Ocean – which designs and builds innovative autonomous underwater vehicles (AUVs) for ocean research.
The collaboration will greatly support the realisation of a complete map of the ocean floor as ecoSUB AUVs are able to navigate areas which are inaccessible to scientists and divers for safety or other reasons.
