About us

Citizens of the Sea began as a partnership between Cawthron Institute and New Zealand Geographic to mobilise and equip seafarers to generate ocean data and support ocean health. 

We work with local partners in each ocean region to form deep connections with communities, agencies and governments to share data and inform ocean health indices, climate predictions and better ocean management.  

In 2024 we recruited 26 offshore cruising yachts, a Pacific voyaging vaka, a commercial vessel and a global racing sailor to use innovative new tools to collect eDNA, environmental data and produce photogrammetric reef models as they traverse the oceans.

In 2025 we established an independent charitable trust, brought on an independent Chair and have set out on the Pacific Rally again to double-down on the eDNA programme and build on the largest dataset of its kind. We have 21 new cruising yachts in the Rally collecting eDNA samples as sail between Aotearoa New Zealand and the Pacific Islands.

    Volker Kuntzsch - Founding Trustee

    Originally from Namibia, Volker has spent his career in the seafood industry spanning five continents. He is currently the CEO of the Cawthron Institute in Nelson, New Zealand. His passion for the ocean was borne out of his favourite pastime in his youth, diving for crayfish on Namibia’s coast, and the connection built over time through fishermen and -women in many different countries interacting with him on and off the water. Safeguarding the health of our ocean, the lifeblood of our planet, supports Volker’s purpose of being a good ancestor.

  • Greg Knowles - Trustee

    Greg’s professional career was as a Chartered Accountant, being a Partner at KPMG for 23 years, advising on company tax.  Before that, he was an Olympic Sailor, for New Zealand, in the Flying Dutchman class at the Seoul and the Barcelona Olympic Games.

    Greg spends time with friends and family on the waters of the Hauraki Gulf, the Southern Lakes and Fiordland.  He appreciates the need to know more about our maritime environment and how to protect it for our tamariki and mokopuna.

  • Anne-Maree Schwarz - Trustee

    Anne-Maree’s career as a scientific diver and scientist has taken her into the lakes and oceans of Aotearoa- New Zealand and Antarctica and reefs of the Pacific Islands. She has spent a number of years sailing offshore from New Zealand while volunteering and working as a marine scientist based in Solomon Islands. An appreciation for the role and potential of citizen science has grown through her experiences of supporting coastal Pacific Islands communities that are remote from centralised services and are seeking to better understand and manage their marine resources through community-based approaches.

  • Rufino Varea - Trustee

    As Director of the Pacific Islands Climate Action Network (PICAN), Rufino spearheads efforts to empower communities and drive climate action. With a PhD in Marine Science from the University of the South Pacific, he has studied the impacts of marine pollutants on critical seafood systems and the associated risks to human health, particularly for Indigenous and coastal communities. His work bridges science with on-the-ground research advocacy; informing policy, and empowering vulnerable populations. Beyond his research advocacy and science-policy work, he amplifies the voices of Indigenous Peoples in the Pacific and supports movement-building efforts through various partnerships and affiliations.

  • Waitangi, Chatham Island

    Originally from Switzerland, Xavier is a marine biologist with over 25 years of research experience across the Indo-Pacific. His work bridges coral symbioses, aquatic ecology, biosecurity, and molecular biomonitoring. Since moving to New Zealand in 2012, he has led pioneering research on environmental DNA (eDNA) to assess biodiversity and ocean health. A founding member of Citizens of the Sea, Xavier brings scientific leadership and infectious curiosity to the mission of making ocean data accessible to all.

  • Northland, New Zealand

    Erin Bomati - Operations Manager

    With a background in enzyme biochemistry and over a decade in the genomics industry, Erin stepped beyond the research to champion citizen science. Driven by a deep passion for ocean conservation, she led an award-winning science outreach program in New Zealand, introducing high school students to the exciting world of marine eDNA. An avid sailor herself, Erin was inspired by the mission to build a global community of sailor-scientists, empowering everyday mariners to make meaningful contributions to the study and protection of ocean health.

Science Advisory Panel

  • Simon Weppe

    Simon is a physical oceanographer from Brittany, France, now based in New Zealand. With over 15 years of experience modeling and analyzing both coastal and open-ocean environments, he has a particular interest in ocean frontal systems and their connections to ecosystems. Driven by a deep passion for the ocean, Simon is committed to bridging the worlds of diverse ocean “users” and ocean science. He has served as a scientific advisor for citizen science projects, focusing on collecting ocean and environmental data from offshore racing yachts such as The Ocean Race. He is now supporting Citizens of the Sea in its effort to expand eDNA sampling across a broader fleet of “vessels of opportunity,” helping to unlock new ways for communities to contribute to ocean science.
