The Galápagos Archipelago consists of several large volcanic islands and an unknown number of small submarine seamounts that are built on top of a ~3 km thick pile of lava flows that form the ...

The Pacific Seamounts Expedition 2021 was a resounding success. From 15 -28 June, a small team of scientists onboard the Canadian Coast Guard Ship John P. Tully conducted 11 dives to nine ...

The new satellite map can sense seamounts less than half that tall. By zeroing in on tiny gravitational “bumps” on the water’s surface, the data predict the position of these newly discovered peaks, ...

This map of ocean floor features like seamounts southwest of Acapulco, Mexico, is based on sea surface height data from SWOT. Purple denotes regions that are lower relative to higher areas like ...

The SWOT satellite can detect seamounts less than half that height, potentially increasing the number of known seamounts from 44,000 to 100,000. Why This Matters Global data from the SWOT satellite.

Previous attempts were limited to large seamounts over a kilometer tall. By detecting sea hills less than half a kilometer high, the number of known features climbed from 44,000 to 100,000. New maps ...

Sandwell and his colleagues used a year’s worth of SWOT data to focus on seamounts, abyssal hills, and underwater continental margins, where continental crust meets oceanic crust. Scientists have long ...

In total, we collected 374 basalts during 15 Alvin dives and 19 dredges. In the coming years, we will measure the major content of all lavas and trace element and radiogenic isotope ratios on a subset ...

Scientists are conducting the first underwater research of offshore banks near Cayman Dotting Cayman’s sea floor are a series of underwater mountains, known as seamounts, and yet, other than ...

Using satellite altimetry data from SWOT, scientists have created a global map of marine gravity, uncovering thousands of new seamounts. (Eötvös is a unit that measures the ocean’s vertical ...

Scientists have started work on a map of the sea floor, which will be completed by 2030. Only nine percent of the surface of the sea floor is on the map, while other parts remain completely unknown, ...
