An important part of our project “Sail for Science” aboard SV Oceanolog is connecting with fellow sailors—and not just over sundowners at the bar or grilled fish by the barbecue. While casual conversations often spark interest, we also love taking things a step further by organizing presentations and sharing our mission more formally.
During our stay at Shelter Bay Marina (Colon, Panama), we hosted just such an event in the marina lounge. I gave a presentation on our two-year expedition through the Caribbean Sea and introduced our CTD (Conductivity, Temperature, Depth) measuring system—the heart of our citizen oceanography work.
The talk covered current methods of collecting oceanographic data, from traditional ship-based CTD systems to autonomous Argo floats. I highlighted the gaps that still exist, particularly in coastal and island regions, and explained how small vessels like ours can play a vital role in closing those gaps.
Our live demo of the CTD system generated a lot of enthusiasm. Several attendees expressed interest in participating or even replicating our methods. The main hurdle, however, remains the cost—CTD systems are still relatively expensive for private cruisers. We discussed the need for funding mechanisms that could support sailors in contributing valuable data, such as grants channeled through research institutions.
Using sailboats to collect ocean data is not only cost-effective, but also has an incredibly low carbon footprint. It’s a sustainable model for grassroots science—and we hope to see it grow.
With time, we believe this project can become part of a global citizen science movement powered by the wind and driven by curiosity. After all, who better to help study the oceans than those already living on them?
