Ancient, hydrogen-rich waters deep underground around the world: Waters could support isolated life

This item was filled under Climate
A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometers beneath Earth's surface in rock fractures in Canada, South Africa and Scandinavia. Common in Precambrian Shield rocks -- the oldest rocks on Earth -- the ancient waters have a chemistry similar to that found near deep sea vents, suggesting these waters can support microbes living in isolation from the surface....

Ocean acidification a culprit in commercial shellfish hatcheries’ failures

This item was filled under Climate
The mortality of larval Pacific oysters in Northwest hatcheries has been linked to ocean acidification. Yet the rate of increase in carbon dioxide in the atmosphere and the decrease of pH in near-shore waters have been questioned as being severe enough to cause the die-offs, researchers report....
