Buried nearly a kilometre beneath the Atlantic seabed west of Guinea-Bissau lies a geological time-capsule: gigantic 117-million-year-old mud waves sculpted by dense, underwater avalanches. A new ...

The vast stretch of ocean between the Americas and Europe may be about to close soon—on a geological timescale. Just before the continents begin to drift back together, an "Atlantic ring of fire" is ...

The Atlantic Ocean may “soon” be swallowed up by a vast chain of colliding tectonic plates that has been ominously dubbed the “Ring of Fire,” scientists warn. The tectonic plate underneath Africa has ...

Key to a chart of the successive geological formations, with an actual section from the Atlantic to the Pacific ocean. Illustrated by the characteristic fossils of each formation. By James Hall ...

Scientists have discovered giant mud waves buried deep below the Atlantic Ocean around 250 miles off the coast of Guinea-Bissau, a country in west Africa. Made of mud and sand, these massive ...

A modeling study suggests a slumbering subduction zone below the Gibraltar Strait is active and could break into the Atlantic Ocean in 20 million years' time, giving birth to an Atlantic "Ring of Fire ...

The basins that flooded in the final rifting of South America and Africa were rich in carbon, and the birth of the ocean would have made the sequestering of carbon less efficient. This reduced ...

The collapse of a crucial network of Atlantic Ocean currents could push parts of the world into a deep freeze, with winter temperatures plunging to around minus 55 degrees Fahrenheit in some cities, ...
