Mapping the Ocean Floor with Ancient Tides
A new study uses a paleotidal model to trace the formation of carbon-rich mud deposits over thousands of years.
Rock Organic Carbon in Soils: Recycled or Just Passing Through
It’s often assumed that all soil organic carbon ultimately derives from recent vegetation, but researchers argue that carbon inherited from parent rocks can be important and deserves more focus.
Glaciers Offer Clues into the Path of Fossil Fuel Pollution
New research traces the origin of carbon deposited from the atmosphere onto glaciers.
Los lagos y estanques de Alaska revelan los efectos del derretimiento del permafrost
Un nuevo conjunto de datos proporciona un método poderoso para rastrear fácilmente los cambios en el permafrost.
Carbon-Nutrient Ratios Drive Nitrate Removal in Mediterranean Streams
The type of organic matter, and ratio of nutrients to carbon, impact the ability of heterotrophic bacteria to effectively remove certain forms of nitrogen pollution (nitrate) from streams.
Erosion: An Overlooked Contributor to the Carbon Cycle
Since physical and chemical erosion yield comparable carbon fluxes, studying both together is essential to avoid biases in erosion-driven carbon flux estimates.
Alaska’s Lakes and Ponds Reveal Effects of Permafrost Thaw
A new dataset provides a powerful method for easily tracking changes in permafrost.
Ceres’s Organics Might Not Be Homegrown After All
Scientists have been unable to determine whether the dwarf planet’s organics were produced by its own chemical processes or delivered by asteroids. New evidence implicates asteroids.
