Real-time seismic monitoring station installed atop active underwater volcano
This week, researchers will begin direct monitoring of the rumblings of a submarine volcano in the southeastern Caribbean Sea. On May 6, a team of scientists led by the Woods Hole Oceanographic Institution installed a new underwater earthquake monitoring system on top of Kick'em Jenny, a volcano just off of the north coast of the island nation of Grenada.(eurekalert)

'Short-circuit' found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week.(eurekalert)

Snowball Fight Erupts over Frozen Earth Theory
The theory that the Earth long ago froze completely over, like a giant snowball, is challenged by new data from desert outcroppings in Oman. The geological measurements indicate that even as glaciers spread across all the continents 700 million years ago, warm spells with liquid water were still common. The question now is how did our planet resist becoming a popsicleHeated debate: Was Earth ever a big snowball? New evidence suggests no.

Arizona State University scientist finds Martian ice is patchy and variable
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Ea(eurekalert)

US conservation efforts bring more marine turtles to UK
US and Mexican conservation efforts may have boosted the number of marine turtles visiting UK waters, according to University of Exeter biologists. This new research analyses 100 years of data and shows an increase in the number of loggerhead and Kemp's ridley turtles in UK and French waters in the last twenty years. The research team believes this is most likely the result of protective measures (eurekalert)

When smell cells fail they call in stem cell reserves
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear online next week in Nature Neuroscience.(eurekalert)

Scientists link volcanic eruptions that formed North Atlantic Ocean to ancient global warming
Scientists examining a spike in worldwide ocean temperatures 55 million years ago have linked it to massive volcanic eruptions that pushed Greenland and northwest Europe apart to create the North Atlantic Ocean. Writing in the journal Science, geologists present evidence that this intense volcanic activity occurred at the same time ocean temperatures jumped five to 6 degrees Celsius.(eurekalert)

Ocean's 'twilight zone' plays important role in climate change
A major study has shed new light on the dim layer of the ocean called the "twilight zone" -- where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.(eurekalert)
