Groundwater May Fix as Much Carbon as Some Ocean Surface Waters

by Carolyn Wilke 28 July 20227 September 2022

Microbes from wells as deep as 90 meters created organic carbon at a rate that overlaps with some nutrient-poor spots in the ocean.

Mysteries of the Global Carbon Cycle

by David Crisp, Han Dolman, Toste Tanhua, Galen A. McKinley, Judith Hauck, Ana Bastos and Stephen Sitch 22 June 202221 July 2022

Less than half of the anthropogenic carbon dioxide remains in the atmosphere to drive climate change. The rest is being removed by mysterious processes in the land, biosphere, and ocean.

The Ocean Is Still Sucking Up Carbon—Maybe More Than We Think

by Nancy Averett 3 May 202214 September 2022

Recent studies looking at carbon-sequestering microbes suggest we still have a lot to learn about the ocean’s biological carbon pump.

The Nutrient-Rich Legacy in the Amazon’s Dark Earths

by Kate Evans 23 March 20227 November 2024

Fertile terra preta soils were created through centuries of carefully managed land use. Scientists are taking cues from these soils to better sequester carbon and improve soil for agriculture.
