科学家们对三个河口进行研究,来寻找海洋溶解黑碳缺失的来源。
carbon
Tracing Black Carbon’s Journey to the Ocean
Scientists surveyed a trio of estuaries in pursuit of a missing source of oceanic dissolved black carbon.
Organic Radiocarbon Reveals its Inorganic Ancestry in Lake Geneva
Organic and inorganic radiocarbon ages resolve the origin and dynamics of carbon in the largest natural lake of Western Europe.
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.
