Early warning indicator hidden within the Gulf Stream could signal the collapse of key Atlantic currents, study finds

Shifts in the Gulf Stream could help researchers predict the human-driven failure of a huge system of ocean currents known as the Atlantic Meridional Overturning Circulation.

Marine snow is the continuous drift of organic debris—such as dead plankton and fecal pellets—from the ocean's surface down to the deep sea, serving as a primary mechanism for long-term carbon sequestration.

Bacteria hitching a ride on “marine snow” may slow the ocean’s carbon sink

In some parts of the deep ocean, it can look like it’s snowing. This “marine snow”

Marine snow is a continuous shower of organic dust and detritus that falls from the upper layers of the ocean to the seafloor, acting as a vital "biological pump" that transports and stores atmospheric carbon in the deep #ocean

Understanding how “marine snow” acts as a carbon sink

Hitchhiking bacteria dissolve essential ballast in ubiquitous “snow” particles, which could counteract the ocean’s ability to sequester carbon.

Planting trees in the sea could act as a huge carbon sink and save millions of dollars in storm damage every year. What is stopping us from doing it?

A new study reveals restoring mangroves could save $800 million in storm damage, protect 140,000 people from flooding, and remove almost triple the amount of CO2 produced by cars in the U.S. every year.

Oceanography is the comprehensive, interdisciplinary study of the Earth's oceans and seas, encompassing their physical properties, chemical composition, biological ecosystems, and geological structures. Its primary goal is to understand the complex, dynamic processes that govern the marine environment, how the ocean interacts with the atmosphere to regulate global climate
