Fertility of the sea: Researchers study how nutrient sources make it to the base of the food web
Virtually all marine life—fish, turtles, sharks, whales and more—depend on the marine food web for survival. The foundation of this immense flow of energy, however, rests on the shoulders of the microscopic but mighty ...

North Atlantic's marine productivity may not be declining, according to new study of older ice cores
To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic ...

Nature's ocean fertiliser
Scientists have discovered that Antarctic krill – a tiny shrimp-like crustacean – plays a key role in fertilising the Southern Ocean with iron, which stimulates the growth of phytoplankton, the microscopic plants at the ...

Research finds multiple nutrients are required for phytoplankton to thrive
Phytoplankton, unicellular photosynthetic microbes, play a fundamental role in the global carbon cycle and fuel marine food webs. Globally, phytoplankton productivity is regulated by the availability of essential nutrients ...

How ancient dust from the sea floor helps to explain climate history
During the last Ice Age about 20,000 years ago, iron-containing dust acted as a fertilizer for marine phytoplankton in the South Pacific, promoting CO2 sequestration and thus the glacial cooling of the Earth. But where did ...

Phytoplankton and zooplankton biomass will decrease 6 and 11 percent due to climate change
It is estimated that ocean temperature warming will cause phytoplankton and zooplankton biomass to decrease by 6 percent and 11 percent respectively by the end of the century. A lower amount of these two main elements in ...

Iodine accelerates formation of cloud condensation nuclei in the atmosphere
The natural cycles of exchange of substances between the biosphere and the atmosphere are of major relevance to the Earth's climatic system. Perhaps the best-known example of this is the carbon cycle that involves the transfer ...
