A vast ocean likely covered one-third of the surface of Mars some 3.5 billion years ago, according to a new study conducted by University of Colorado at Boulder scientists.
(PhysOrg.com) -- Living beings and inanimate phenomena may have more in common than previously thought.
A breakthrough study of fluctuations in sea levels the last time Earth was between ice ages, as it is now, shows that oceans rose some three meters in only decades due to collapsing ice sheets.
Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta – once a massive green estuary of grassland, marshes and cottonwood, now desiccated dead land.
Scientists studying deltas show how they may be able to predict where destructive changes in a river's course may occur.
One of the most recognizable constellations in the sky is Orion, the Hunter. Among Orion's best-known features is the "belt," consisting of three bright stars in a line, each of which can be seen without a telescope.
In a country where most people live below sea level, studying the oceans is a matter of survival. Now Dutch scientists have created the world's biggest man-made wave in a bid to prepare for the worst.
Coastal deltas are becoming more at risk of flooding due to land subsidence, or the gradual sinking of the Earth's surface, and sea-level rise.
The Mississippi River delta is a rich ecosystem of barrier islands, estuaries, and wetlands that's home to a diverse mix of wildlife—as well as more than 2 million people. Over the past few decades, the shape of the delta ...
To measure distances in the universe, astronomers use cepheids, a family of variable stars whose luminosity varies with time. Their role as distance calibrators has brought them attention from researchers for more than a ...
