In January 2022, the largest submarine volcanic eruption of this century led to a dramatic phytoplankton bloom north of the island of Tongatapu, in the Kingdom of Tonga. A team of scientists from the University of Hawai'i ...
The ocean floor is famously less explored than the surface of Mars. And when our team of scientists recently mapped the seabed, and ancient sediments beneath, we discovered what looks like an asteroid impact crater.
An underwater volcano in the Pacific Ocean has begun to erupt, NASA images show. Living there: Sharks that can withstand extreme temperatures.
On 15 January, the eruption of a submarine volcano in the Tonga archipelago destroyed 90% of the uninhabited island of Hunga Tonga Ha'apai and formed an ash plume half the size of France. It also generated an atmospheric ...
Earthquakes are famously impossible to predict, and have been the cause of some of the most devastating events in human history. But could we learn more about these natural disasters by tracking them backwards through time?
During another time in which Earth warmed rapidly in conjunction with a spike in atmospheric carbon similar to our modern climate, seawater temperature and chemical changes decimated an important piece of the food web in ...
The presence of pink pumice in the giant pumice raft of the 2012 Havre eruption that drifted across the southwest Pacific Ocean has led researchers to recognize the immense power of underwater volcanic eruptions.
The scale of a recent volcano eruption took the people of Tonga by surprise. Scientists monitoring the submarine volcano, Hunga Tonga-Hunga Ha'apai, were likewise caught off-guard, failing to foresee an explosion which would ...
Two University of Wyoming researchers are part of the first-ever mapping of magnetic stripes—one of the foundations of plate tectonics—within the lower gabbroic section of fast-spreading oceanic crust.
Looking like the Eye of Sauron from the Lord of the Rings Trilogy, an ancient undersea volcano was slowly revealed by multibeam sonar 3,100 meters below our vessel, 280 kilometers southeast of Christmas Island. This was on ...
