Emissions from coal-fired power plants and possibly other sources in China are seeding the North Pacific Ocean with metals including iron, a nutrient important for marine life, according to new a new study.

Interest in deep-sea mining for metals has grown substantially in the last decade. A new study argues that it poses significant risks not only to the immediate surroundings, but also to the water hundreds to thousands of feet above the seafloor.

Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study.
Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean. “Phytoplankton serve as food for all of the fish and animals that live there. Everything that eats is eating them ultimately,” said Kevin Arrigo, a biological oceanographer at Stanford University and lead author of the study.

In the water above natural oil seeps in the Gulf of Mexico, where oil and gas bubbles rise almost a mile to break at the surface, scientists have discovered something unusual: phytoplankton, tiny microbes at the base of the marine food chain, are thriving. The oil itself does not appear to help the phytoplankton, but the low concentration of oil found above natural seeps isn’t killing them, and turbulence from the rising oil and gas bubbles is bringing up deep-water nutrients that phytoplankton need to grow, according to a new study appearing in the latest issue of Nature Geoscience.
