Radar satellites supply the data used to map sea level and ocean currents. However, up until now the radar's 'eyes' have been blind where the oceans are covered by ice. Researchers at the Technical University of Munich (TUM) have now developed a new analysis method to solve this problem.
A moss capable of removing arsenic from contaminated water has been discovered by researchers from Stockholm University. And it happens quickly -- in just one hour, the arsenic level is so low that the water is no longer harmful for people to drink. The study has been published in the journal Environmental Pollution.
Geologists have discovered that some magmas split into two separate liquids, one of which is very rich in iron. Their findings can help to discover new iron ore deposits for mining.
The cyclic strengthening and weakening of ocean tides over tens of millions of years is likely linked to another, longer cycle: the formation of Earth's supercontinents every 400 to 600 million years, according a new study.
A recent study published in an esteemed academic journal indicates that volcanic eruptions in the mid 500s resulted in an unusually gloomy and cold period.
The Atlantic overturning circulation is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature. Human-made climate change is a prime suspect for these worrying observations.
Glaciers in Alaska's Denali National Park are melting faster than at any time in the past four centuries because of rising summer temperatures, a new study finds.
Megathrust earthquakes are the most powerful type of earthquake, occurring at subduction zones -- where one tectonic plate is pushed beneath another. By contrast, slow slip events (SSEs) release seismic stress at a lower rate than large earthquakes, re-occurring in cycles. These processes can take place along the megathrust and other planes of weakness in response to loading, releasing low frequency seismic waves. Researchers in Japan consider the fluid drainage processes that can occur from SSEs and their impact on seismic activity.
An Ohio University geologist who first proposed the now-accepted supercontinent cycle theory in the 1980s has rallied to the cause of one of those supercontinents, Pannotia, that is in danger of being overlooked.
Scientists have discovered that the seafloor from the Mississippi River Delta to the Gulf of Mexico is eroding like the land loss that is occurring on the Louisiana coast. This research was published recently in the journal Marine Geology.
