Good news about the ocean
Hopeful ocean news: reefs recovering, new marine protected areas, whales returning and cleaner seas, scored for positivity.
The ocean covers most of the planet and gets a small share of the good news.

Here you’ll find those stories alongside work on cleaner coastlines, smarter fishing and ocean science that explains how the sea works. They come from trusted publishers and update as new stories arrive.
