Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

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

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.

Affordable Robots Measure Soil Respiration

by Emily Dieckman 8 December 20238 December 2023

Measuring soil carbon flux, also known as soil respiration, can be expensive or time-consuming. A set of affordable robots that gather these data autonomously could especially benefit the Global South.

Weathering of Rocks Can Release Carbon Dioxide

Rachel Crowell, Science Writer by Rachel Crowell 28 November 202329 November 2023

New research upends the notion that the weathering of rocks mainly removes CO2 from the atmosphere. Rocks can also be carbon sources, releasing as much CO2 as Earth’s volcanoes.
