Where Kelp Carbon Goes: The Pathways from Canopy to Deep Sea
Kelp forests don't bury carbon where they grow — they export it. Tracing fragments, dissolved carbon and currents from canopy to the deep sea, and how science tracks them.

Marine Snow: The Ocean's Slow Carbon Conveyor
Marine snow is the ocean's constant drizzle of sinking organic matter — and one of the main routes by which carbon reaches the deep sea. Here's how it works.
