A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and isotopic techniques to better understand the carbon ...

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean acidification reduces primary production, the process of photosynthesis in ...

Ocean ecosystems form a huge active carbon sink and play a critical role in the global carbon cycle and climate. Blue carbon refers to the carbon captured and stored by marine ecosystems ...

How is organic matter transported from productive coastal areas to the open ocean? Researchers have now shown that eddies play a crucial role in this process. The swirling currents contain large ...

Hurricanes move massive amounts of sediment from shallow reefs to deep oceans, affecting ecosystems long-term.

“Because they experience these very strong changes in their ecosystem in ways that we can perceive ... Whales in turn play a ...

Mesoscale eddies, oceanic gyres about 100 kilometers in diameter, are ubiquitous features of the global ocean and play a ...

By reducing the acidity of surrounding waters, seagrass ecosystems help protect animals with shells or external skeletons. Like land plants and seagrasses, microscopic marine algae known as ...

This is important. Marine ecosystems can be both sinks or sources of carbon. If we don’t understand how organic material is transformed or how carbon dioxide (CO₂) is either taken up by plants ...
