Shipwrecks can become thriving reefs, but may contain hidden toxic time bombs

Late last year, scientists in Germany published findings on a World War II munitions dump in the Baltic Sea. Some may dismiss the dump as hazardous waste, but to marine biologists it was something far more exciting: a thriving ...

The internal chemistry of phytoplankton changes as oceans become more acidic

Our oceans are becoming more acidic, which could have major consequences for marine life. Of particular concern is what this could mean for phytoplankton, the microscopic photosynthetic organisms that form the basis of marine ...

Why a healthy seafloor matters for the Earth system

The seafloor is more than just the ground beneath the sea. Two-thirds of Earth's surface is covered by oceans, which have an average depth of almost 4 kilometers (2.5 miles). For a long time, the seafloor's remoteness protected ...

Adding limestone to Mississippi River Basin farmlands acts as a major carbon sink, study finds

In a discovery as broad and far-reaching as the Big Muddy itself, a new Yale–led study says farmers in the Mississippi River Basin are storing more carbon dioxide (CO2) in the soil than they emit when they add limestone to ...

Climate change is making it easier for invasive species to succeed

In 2017, Hurricane Maria made landfall on Puerto Rico with maximum sustained winds of 250 kilometers per hour (155 mph). It devastated communities and infrastructure, was associated with nearly 3,000 deaths and caused tens ...

Tiny oyster larvae rely on gravity to feed

Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution ...

Ocean acidification may disrupt diatoms' carbon capture and marine food webs

Our oceans are in trouble, and new research from Flinders University shows how changes in diatoms (microalgae) could further undermine the foundation of aquatic food webs—as well as vital deep-sea carbon capture or sequestration.

Survey reveals marine biodiversity hotspot needs protection

An environmental DNA study by a multi-institutional research collaboration has revealed distinct regions of extraordinary marine biodiversity that can help inform management of a proposed marine park in Western Australia's ...

Ocean antacid trials test plankton response in 8,000-liter seawater enclosures

All the forests in the world pale in comparison to the ocean when it comes to absorbing carbon dioxide from the atmosphere. The ocean is the world's largest natural carbon sink, absorbing about a quarter of all CO2 emissions ...
