Stretching of the continents drove ancient global warming event, say scientists -

During this time, the planet experienced an increase in temperature of 5-8°C (9-14°F), culminating in the Paleocene-Eocene Thermal Maximum (PETM), which lasted about 170,000 years.

This massive floating laboratory developed in Japan was the first to introduce the riser technology, inspired by the one used by oil rigs, to the world o...

Scientific ocean drilling is an enduring paragon of global research, advancing knowledge of Earth and informing scientists and educators for 55 years. A new road map plots the way to further discovery.

Drill preparation. The team prepare the deep-sea drill for use on the seafloor. © 2021 JAMSTEC-IODP Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes. For the first time, researchers use deep-sea boreholes to gauge pressures far below the seafloor. They hope data from this and future observations ...
