Alligators May Boost Carbon Storage in Coastal Wetlands
Research suggests that American alligators help coastal wetlands retain more carbon, linking predator recovery in the southeastern United States to ecosystem function and climate processes.
Marine Snow Grows Faster and Fluffier as It Sinks
New observations highlight how abiotic and biotic processes influence the tiny oceanic particles.
Managing Carbon Stocks Requires an Integrated View of the Carbon Cycle
The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.
New River Chemistry Insights May Boost Coastal Ocean Modeling
By more realistically accounting for river inputs, researchers reduced overestimation of the amount of carbon dioxide absorbed by coastal waters.
What Could Happen to the Ocean’s Carbon If AMOC Collapses
Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.
Wintertime Spike in Oceanic Iron Levels Detected near Hawaii
Seasonal rainfall and runoff of sediments from the Hawaiian Islands could be responsible for the previously undetected peak.
A Better Way to Monitor Greenhouse Gases
A unified, global observing system could more effectively monitor progress in reducing emissions and accelerate climate action through improved data and decision support.
The Southern Ocean May Be Building Up a Massive Burp
Modeled results suggest that if anthropogenic emissions decrease and the atmosphere cools, heat stored in the Southern Ocean could be released abruptly in a few hundred years, kicking off a temporary warming period.
