It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for […]

A new study helps explain how and why columns of methane gas can stream out of seafloor formations known as methane hydrates. Credit: Image courtesy of the NOAA Office of Ocean Exploration and Research, Gulf of Mexico 2017. Leakage from frozen layers was a puzzle, but a new study shows […]

A thin section of an ice core collected at Taylor Glacier in Antarctica. The ice core samples contain tiny air bubbles with small quantities of ancient air trapped inside. The researchers use a melting chamber to extract the ancient air from the bubbles and then study its chemical composition. The […]

The Arctic is one of the […]
