Seismic waves traveling in between the Earth's poles travel faster than those between the equator - one sign of the textured nature of Earth's solid iron inner core. A recent study from KTH explains how the core retains its...
Summary of the locations where gas hydrate occurs beneath the seafloor, in permafrost areas, and beneath some ice sheets, along with the processes (shown in red) that destroy methane (sinks) in the sediments, ocean, and atmosphere. The differently colored...
With the ocean absorbing more carbon dioxide (CO2) over the past decade, less of the greenhouse gas is reaching the Earth's atmosphere. That's decidedly good news, but it comes with a catch: Rising levels of CO2 in the ocean...

The researchers analysed quartz crystals from Toba, and found a distinct shift in the isotopic composition towards the outer rim of the crystals. Credit: Troll et al.
Researchers have now found an explanation for what triggered the largest volcanic eruption...
In some places along the Antarctic coast, ice formation causes seawater to grow saltier and therefore denser, so that it sinks to the sea floor. Known as the Antarctic Bottom Waters (AABW), these deep, cold waters play a critical...

Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an...

An international team of researchers has managed to pinpoint, to within three months, a medieval volcanic eruption in east Asia the precise date of which has puzzled historians for decades. They have also shown...
