Seaweed on sandy coastlines contributes to greenhouse gas emissions, study shows
A team of researchers from Monash University has made a discovery that could reshape our understanding of greenhouse gas emissions from coastal ecosystems. Published in Nature Geoscience, the study reveals sandy coastlines, which make up half the world's continental margins, are a previously overlooked source of methane.

Marine life are thriving on Nazi missile debris in the Baltic Sea: Study
As Germany demilitarized after World War II, it dumped massive amounts of its leftover munitions into the Baltic Sea. A recent study has found that some of those submerged weapons, which are still releasing toxic compounds, now host more marine organisms than the sediments around them. In October 2024, researchers used a remotely operated vehicle […]

Sharks risk losing their bite as oceans turn acidic: Study
Sharks continually shed and regrow teeth throughout their lives, replacing worn or lost teeth with new ones. That makes them particularly good at catching prey. However, these top marine predators could lose their literal edge as ocean acidification damages their teeth and makes it harder to keep and replace them, a new study says. “Shark […]

Plastic pollution could linger at ocean surfaces for over a century, new research finds
Scientists from the Department of Geography and Environmental Science at Queen Mary University of London have developed a simple model to show how buoyant plastic can settle through the water column and they predict it could take over 100 years to remove plastic waste from the ocean's surface.
