Fogo Seamounts, Underwater volcanic chain in North Atlantic Ocean, Canada
The Fogo Seamounts are a chain of more than forty cone-shaped underwater mountains that rise over 3000 feet (1000 meters) above the North Atlantic Ocean floor southeast of Newfoundland. These mountains are spread across vast areas of the seafloor and form a system distinguished by their varying heights and geological composition.
These volcanic formations emerged during the Early Cretaceous period roughly 125 to 150 million years ago. The seamounts are remnants of ancient volcanic activity that shaped the geological history of the North Atlantic.
Research teams from Canadian institutions regularly study these underwater mountains to understand North Atlantic geological patterns and their importance for ocean ecosystems.
Marine researchers access information about these underwater formations primarily through scientific publications and resources provided by the Geological Survey of Canada. Data collection and study of this remote location rely on specialized oceanographic methods and equipment.
Several seamounts in this chain feature flat eroded summits at depths between 3000 and 4500 meters. These flattened peaks reveal that these mountains once existed as volcanic islands above the ocean surface before gradually subsiding beneath the waves.
