The Nutrient-Rich Legacy in the Amazon’s Dark Earths
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.
A Global Ocean Biogeochemical Observatory Becomes a Reality
Building on the successful Argo network of seafaring temperature and salinity sensors, work is underway to deploy 1,000 floats equipped to study ocean biogeochemistry in greater detail than ever.
¿Cuánto tiempo permanecen las partículas de carbono negro en la atmósfera?
Investigadores descubren cómo el carbono negro evoluciona de partículas hidrofóbicas a sitios de nucleación de nubes, removiendo eventualmente las partículas que absorben calor del cielo.
The Seasonality of Oceanic Carbon Cycling
Scientists uncovered how seasonal changes affect the amount and rate of carbon as it moves from the ocean’s surface to its depths.
Pequeños cambios climáticos podrían verse magnificados por procesos naturales
Un nuevo estudio utiliza técnicas de modelado para descubrir cómo pequeños incidentes de calentamiento pueden convertirse en eventos hipertermales que duran miles de años.
Bubble, Bubble, Toil and Trouble: Ocean Vents Spew Rubble
Hydrothermal vents in the ocean emit 6000-year-old carbon. The likely source? Ocean crust.
Mapping a River Beneath the Sea
A recent expedition mapped one of the world’s longest submarine channels, revealing previously undiscovered physical features and raising questions about its unusual origin and shape.
Soil Texture Affects How Carbon Is Stored Underground
Using measurements from more than 9,300 soil samples collected worldwide, researchers have shown that carbon storage in soils is affected by both air temperature and soil texture.
Large Herbivores May Improve an Ecosystem’s Carbon Persistence
The grazing habits of wild animals like elephants and boars enable long-term carbon storage, according to new research that stresses the need to align climate mitigation goals with biodiversity conservation.
