Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle
While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.

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