Suspending Life. "If almost every species on Earth was killed some 250 million years ago, how did our ancient ancestors survive and evolve into us?"

British diplomat William Hamilton (whose 2nd wife Emma is perhaps best known for having a scandalous public affair with Horatio Nelson) loved volcanoes. His 1776 book Campi Flegrei: Observations on the volcanoes of the two Sicilies* used stunning hand-coloured illustrations by Peter Fabris to demonstrate to the scientific world that volcanic processes can be beautifully creative as well as horribly destructive.

There are holes in the earth's crust! It turns out that the ozone layer was just keeping up with the Jones's; in the middle of the Atlantic ocean, there is a patch of several thousand square kilometers where the mantle is exposed. 'The team of scientists from Cardiff University stress there is no need for the public to panic about the giant hole even though they describe it as "a gaping open wound in the Earth's skin".' The scientific team departs today to investigate the hole. They will be detailing their progress on a blog. And you can ask them questions about their project, which they may answer online.

The site design is somewhat unfortunate, but The Virtual Cave features lots of photos and information on, well, caves and cave formations. We've all heard of stalagmites and stalactites, but I'd never heard of cave draperies or cave pearls before. Then you've got your helictites, your aragonite, and your splash stalactites (found in lava tubes). And they've got a Show Caves Directory of caves in the United States that are open to the public, with addresses and contact information by state.

Athanasius Kircher was the 17th century's Jesuit version of the übergeek. His scholarly attentions were drawn to egyptology, astronomy, magnetism, languages, optics, music, geology, mathematics and many many other pursuits. The "dude of wonders" invented novel machines such as the mathematical organ and magnetic clock, established one of the first museums, published about 40 academic works (with beautiful accompanying illustrations) and was globally revered as one of his time's greatest intellectuals. He is also the main link in the Voynich manuscript mystery. [MI]

The Stellwagen Bank National Marine Sanctuary region is under the ocean, off the coast of Massachusetts. For 11 years geologist Paul Valentine has been mapping this area. Sea floor maps are available. Also, there are many images of features such as glacial valleys and moraines. Other photographs show underwater life.

Instead of liquid water, Titan has liquid methane. Instead of silicate rocks, Titan has frozen water ice. Instead of dirt, Titan has hydrocarbon particles settling out of the atmosphere, and instead of lava, Titanian volcanoes spew very cold ice.

Can we predict volcanic eruptions? PBS aired a NOVA program called "Deadly Shadow of Vesuvius" in 1998 which suggests that we can by monitoring small scale earthquakes which "swarm" as an eruption approaches. Why is this important now? Look at this map, which indicates the occurence of over 40 earthquakes under Mount St. Helens just today, with 10 being over 3.0 on the Richter scale. The Pacific Northwest Seismograph Network has issued a series of alerts with more detail. National Geographic is reporting that an eruption is imminent.

Quake to hit LA "by September 5," predicts a geophysicist at UCLA's Institute of Geophysics and Planetary Physics. Some skeptical, while others say it's not junk science.

Bus-size jade boulders found in Guatemala Great NY Times story [Google'd here] of archeologists tracking down a mother lode of translucent blue jade after it was exposed by a hurricane. The vein solves the mystery of where the ancient Olmecs got the jade for beautiful carvings like these. Olmec civilization, famous for its colossal stone heads, is itself considered something of a mother lode for later Central American peoples like the Maya. Meanwhile, some scientists in Guatemala are digging up things that are much less fun than jade.

Next Thursday, NASA will announce the discovery of huge water ice oceans on Mars. Lying less than a metre beneath the surface south of 60° latitude, the water ice reservoirs if melted would form an ocean 500m deep covering the entire planet. NASA insiders believe these findings could result in a manned landing within 20 years.
