When the ocean heats up, urchin love life cools down. New Hakai-linked study shows that even modest, non-lethal warming can suppress purple sea urchin reproduction — a twist that could temporarily help kelp forests recover. But both kelp and urchins feel the heat.

🔍 Has anyone come across transparent antifouling coatings for u/w camera lenses?
We’re looking for something commercially available in the EU, safe for static u/w cameras that will keep lenses clear without frequent manual cleaning.
Any leads, experiences, or suppliers would be very welcome! 🌊📷
