Atlantis Bank: A Mountain Under the Sea

For over a month now, the JOIDES resolution has maintained its position in the southwest Indian Ocean, 700 meters above Atlantis Bank. This undersea mountain was named in 1986 by one of our co-chief scientists Henry Dick, “we found a block that had been lifted up to sea level, it was an island at one point” says Dick, “so we named it Atlantis Bank after of course the lost city of Atlantis”. read

Brian Switek covers some nice work by our colleague, Federico Fanti: The biggest sea-dwelling crocodile ever found has turned up in the Tunisian desert. The whopper of a prehistoric predator grew to over 30 feet long (nearly ten meters) and weighed three tons. Paleontologists have dubbed the new species Machimosaurus rex and describe it Monday in the journal Cretaceous

The goal of expedition 360 is to drill hole U1473 as deep as we possibly can in the two months we have onboard the JOIDES Resolution. Our target is 1300 meters, this would be the third deepest hole ever drilled into oceanic crust (ie. hard igneous and metamorphic rocks, we’re not counting the sediments that sit on top). read

The Late Cretaceous mosasaur, Phosphorosaurus ponpetelegans (a phosphorus lizard from an elegant creek), is believed to have hunted on glowing fish and squids at night. Phosphorosaurus is relatively small, about 3 meters, or 10 feet long. This unique discovery in a creek in the town of Mukawa in northern Japan reveals that they were able to colonize throughout the northern hemisphere. It

The latest team celebration is around the magnetometer data. Magnetics has evolved quite a bit over the years of geophysical sampling. Lamont scientist Robin Bell recalls when in the 1990s working on a project in West Antarctica that the magnetometer was towed on a winch ~100 meters behind the aircraft - now it is nearly cheek to cheek with other

Excavating Prototaxites From around 420 to 350 million years ago, when land plants were still the relatively new kids on the evolutionary block and “the tallest trees stood just a few feet high,” giant spires of life poked from the Earth. “The ancient organism boasted trunks up to 24 feet (8 meters) high and as wide as three feet (one meter),” said National Geographic in 2007.

Hurricane Patricia on Friday morning 10/23/2015, from Weather.comAs I write this, Hurricane Patricia is less than 100 miles off shore of Mexico, aiming for landfall south of Puerto Vallarta and north of Manzanillo.  Evacuations have been underway. Mexico's second largest city Guadalajara lies inland fortunately south of the projected path that will take it into southern Texas. It is expected to make landfall Friday afternoon or evening, and to fizzle out near Monterrey on [...]

Tubewells to the Rescue

The resistivity was hampered by bad roads and flooded fields. At one point we needed to do a makeshift repair with sandbags and bricks to get through. The augering was proving similarly difficult in the thick muds of the abandoned channel. We were using up our time and making limited progress. It was time to change to our alternative plan. We switched to drilling with tube wells, a local hand-drilling technique. In the time it took us to auger to less than 5 meters, we drilled two tube [...]

Archaeologists using high-resolution ground penetrating radar (GPR) have located a massive collection of stones less than 3 km from the well-known Stonehenge site. This grouping of 90 stones, up to 4.5 meters tall (14.7 feet) have apparently been pushed over and buried. Renderings of the site have been created showing what the row of stones would have looked like. The exact purpose and how this site relates to Stonehenge is still a mystery.

Ocean waves are powerful. Extremely powerful. Waves are one of the few erosional processes that operate within a time frame that can be perceived by humans. Gigantic rocks may be moved in one storm, and coastal cliffs can be eroded at rates that are measured in feet or meters per year. Rock can be extremely hard to erode, but if there is a weakness in the rock, it will be exploited by
