Mediciones pareadas de gases: ¿un nuevo trazador biogeoquímico?
Una técnica que mide la relación entre el dióxido de carbono producido y el oxígeno consumido podría mejorar las predicciones de la respuesta del suelo al cambio climático.
The Ocean Is Still Sucking Up Carbon—Maybe More Than We Think
Recent studies looking at carbon-sequestering microbes suggest we still have a lot to learn about the ocean’s biological carbon pump.
Paired Gas Measurements: A New Biogeochemical Tracer?
A technique that measures the ratio of carbon dioxide produced to oxygen consumed could improve predictions of soil’s response to climate change.
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.
