The team discovers “dark oxygen” at the bottom of the sea
Credit: CC0 Public Domain Children always ask, “Why?” It’s natural to want to know more as they are the first time they’re experiencing things. But as children grow into adults, they often dismiss something new that challenges their experiences and understanding. This happened when we discovered a source of oxygen production in the deep sea, but we ignored it for…

“Preventive measures” are the logical method for deep sea mining, researchers say
A state that has expressed a specific position in international submarine authorities. Credit: rifs@gfz Pressure on the International Submarine Authority (ISA) has finalized and adopted regulations on deep sea mining. While some ISA members hope for immediate progress, more and more states are demanding more time to study the environmental impact of raw material mining on the seabed and develop…

The size of the teeth of South American sea lions reflects historical changes in population abundance
Credit: Ilyn Sosa Druville A new study published in Peerj reveals that the teeth of South American sea lions (Otaria Byronia) have valuable clues on past population dynamics. Researchers from the Instituto de BiologÃa de Organismos Marinos, the Centro para el Estudio de Sistemas Marinos, and the Universidad Nacional de la Patagonia San Juan Bosco analyzed changes in tooth size…

The Arctic groundwater supplies more carbon to the sea than previously known.
An aerial image of the research site in Kakutobik Lagoon in North Alaska. Credit: Nathansongdaman A new study at Austin School at Texas University allows relatively small amount of groundwater to release a large amount of carbon through the Alaska tundra and contribute to climate change. Researchers consist of only a small part of the water that is excreted in…

In high emission scenarios, the sea surface of the world is very likely to rise between 0.5 and 1.9 meters by 2100.
Expert judgment is essential through the process of predicting the rise in the sea level. The arrow shows the flow of information from experts (green arrows) and probable projections (blue arrows). Credit: The future of the earth (2024). Doi: 10.1029/2024EF005295 The interdisciplinary team of NTU Singapore and Delft Institute of Technology (TU DELFT) in the Netherlands predicts that the emission…

Warm seawater intrudes into Antarctica’s main ice shelf, raising concerns about sea levels
Schematic map of the Filchner Trough region on the eastern continental shelf of the Weddell Sea. Credit: Journal of Geophysical Research: Oceans (2024). DOI: 10.1029/2023JC020700 The vast Antarctic ice sheet stores more than half of the earth’s fresh water. In some places on the continent, the ice extends over the ocean, where it forms large floating shelves. Observations show that…
