Emissions from coal-fired power plants and possibly other sources in China are seeding the North Pacific Ocean with metals including iron, 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.

Driven by changing climate, a uniquely resilient organism is taking over the Arabian Sea, disrupting food chains, fisheries, oil refineries and water desalination plants.

A new study reveals a surprising way in which lava influences marine ecology.

MPA in Environmental Science and Policy student Shirley Binder aims to incorporate environmental policy fundamentals into her marine biology background.

The students are using deep learning and neural networks to create an automated system that classifies plankton for large-scale oceanographic studies.

A video reveals mature jellyfish under the Arctic sea ice, where they aren’t supposed to be.

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…. read more

On every continent and ocean, Earth Institute field researchers study the dynamics of climate, geology, ecology, human history and more. Here is a list of expeditions going on this year, and beyond.

Andy Juhl and Craig Aumack, microbiologists from Columbia University’s Lamont-Doherty Earth Observatory, are spending a month in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms.
