Jet-Propelled Tunicates Pump Carbon Through the Oceans
New research reveals that blooms of the widespread gelatinous zooplankton—along with their feces, daily vertical migrations, and carcasses—increase marine carbon export.
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
Tropical Wetlands Emit More Methane Than Previously Thought
Climate models could be vastly underestimating methane emissions from the world’s tropical wetlands, according to observational surveys of wetlands in Zambia.
A New Look at Preindustrial Carbon Release from the Deep Ocean
New research could help inform future studies of how the release of carbon dioxide from the Southern Ocean might affect global climate change.
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.
Inventorying Earth’s Land and Ocean Greenhouse Gases
A new special collection in AGU journals will present findings from the Second REgional Carbon Cycle Assessment and Processes (RECCAP2) study with a decade of data on greenhouse gas growth.
