Soon-to-End Mercury Mission May Hold Clues to Earth’s Evolution

NASA's MESSENGER spacecraft has been orbiting Mercury for the last four years, giving scientists an unprecedented look at our solar system's innermost planet. But now the craft's fuel supply is exhausted; inexorably drawn in by Mercury's gravity, it is scheduled to crash in April. Sean Solomon, director of Columbia University's Lamont-Doherty Earth Observatory, has been leading the mission, and in this video, he talks about its

I chatted with Dr. Naomi Oreskes about her book Merchants of Doubt last December at the AGU in San Francisco. She told me about the movie, and I hope to see it soon. Dr. Oreskes published a stunning paper in Science in 1994 looked at the level of scientific consensus on climate change. What she found was stunning to many scientists in other fields, and since then other studies have also shown just how

Iceland's Bardarbunga Volcano Eruption Pauses

The long-running eruption of Iceland's Bárðarbunga volcano has paused, or ceased. Webcam footage no longer is showing any lava coming out of the eruptive fissure, and scientists visited the site to assess the landscape, only to find a degassing crater.The stoppage of the eruption at Holhuraun fissure is likely not the end of the activity. As this is a rifting episode, it is likely that magma chamber re-inflation will eventually occur. Seismicity is ongoing, although a lot lower than it [...]

More urban heat; less summer fog, on California coast 

AGU Meetings [2015-03-05 21:34:38]  recommend  recommend this post  (33 visits) info

The summer fog that shrouds coastal southern California – what locals call the June Gloom – is being driven up into the sky by urban sprawl, according to scientists who have studied 67 years of cloud heights and urban growth in the region. Less fog may, at first, seem like a good thing. But less fog is bad news for native plants in the coastal hills and mountains, which depend on the cool fog as their only source of water during the rainless summer months. So less fog means warmer, drier, [...]

On 28 February, an earthquake of MW4.4 occurred in the Fucino Basin in Central Italy. The event did not cause any damage and was not widely felt. Such an earthquake is nothing special for this area, but it’s interesting because from 19-24 April the 6th INQUA meeting on paleoseismology will be held in Pescina. The conference will bring together scientists from all around the world to discuss latest develoments in active tectonics, paleoseismology and similar topics, and its date

Saharan dust feeds Amazon rainforest just enough to replace lost nutrient

The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rainforest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. Scientists have not only used a satellite to measure the volume of dust that makes this trans-Atlantic [...]

Yes! Life suddenly became different. Many of us, mostly the scientists, who were sailing on-board the JOIDES Resolution as well as on an International Ocean Discovery Program expedition for the first time, had been occupied for the first few days to adopt the new life on-board, and to learn techniques that would be used for the research during the cruise. read
