Eukaryotic phytoplankton decline due to ocean acidification could significantly impact global carbon cycle
Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean acidification reduces primary production, the process of photosynthesis in phytoplankton, where they take in carbon dioxide (CO2), sunlight, and nutrients to produce organic matter (food and energy).
For microscopic organisms, ocean currents act as 'expressway' to deeper depths, study finds
Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
A chemical mystery solved—the reaction that explains large carbon sinks
A mystery that has puzzled the scientific community for more than 50 years has finally been solved. A team from Linköping University, Sweden, and Helmholtz Munich have discovered that a certain type of chemical reaction can explain why organic matter found in rivers and lakes is so resistant to degradation. Their study has been published in the journal Nature.
Even inactive deep-sea 'smokers' are densely colonized by microbial communities, study shows
Under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team that includes researchers from MARUM—Center for Marine Environmental Sciences at the University of Bremen, is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Microbial awakening restructures high-latitude food webs as permafrost thaws
Alaska is on the front lines of climate change, experiencing some of the fastest rates of warming of any place in the world. And when temperatures rise in the state's interior—a vast high-latitude region spanning 113 million acres—permafrost there not only thaws, releasing significant amounts of its stored carbon back into the atmosphere where it further accelerates rising temperatures, but also decays.
Underground fungi absorb up to a third of our fossil fuel emissions
Researchers estimate that plants transfer more than 13 gigatonnes of carbon dioxide each year to mycorrhizal fungi, which grow around their roots
