The Open Ocean, Aerosols, and Every Other Breath You Take

by Rachel Shelley, Morgane M. G. Perron, Douglas S. Hamilton and Akinori Ito 1 March 20241 March 2024

Phytoplankton and other marine plants produce half of Earth’s atmospheric oxygen and have big effects on food webs and climate. To do so, they rely on nutrients from the sky that are hard to quantify.
