Eocene ungulates were very selective in their feeding

A study by the UPV/EHU-University of the Basque Country into the paleodiet of extinct paleotheriidae (or pseudo horses) provides information about their feeding strategy and the environment they inhabited at the end of the ...

The seasonality of oceanic carbon cycling

The ebb and flow of carbon within Earth's systems are complex and ever-moving occurrences. Carbon is a nomadic element, traveling between the atmosphere, ocean, and the soil, rock, and ice of the planet, changing forms along ...

New insights into seasons on a planet outside our solar system

Imagine being in a place where the winds are so strong that they move at the speed of sound. That's just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot ...

Spatial-temporal structure of ocean salinity seasonal variation

Salinity is always regarded as a natural water gauge. It plays a vital role in regulating ocean density, stratification and circulation. However, a holistic analysis of subsurface salinity down to 2,000 meters is lacking, ...

Seismology: A promising tool for monitoring permafrost

The warming and thawing of permafrost in response to rising temperatures are increasingly destabilizing rock slopes, causing more occurrences of rockfall in recent years. This trend is expected to continue, raising concerns ...

How much carbon dioxide snow falls every winter on Mars?

Like Earth, Mars experiences climatic variations during the course of a year because of the tilted nature of its orbit (aka. seasonal change). Similarly, these variations in temperature result in interaction between the atmosphere ...

Scientists use seasons to find water for future Mars astronauts

An international team of researchers has used seasonal variations to identify likely sub-surface deposits of water ice in the temperate regions of Mars where it would be easiest for future human explorers to survive. The ...
