Drilling deep 

AGU Meetings [2015-02-25 17:18:32]  recommend  recommend this post  (30 visits) info
We’re in the Indian Ocean currently drilling the deepest of a six hole transect across the middle of the Bengal submarine fan. The fan covers the bottom of the Bay of Bengal with sediments eroded from the Himalayas. We’ll be devoting almost three weeks of our eight-week International Ocean Discovery Program expedition to drilling at this site. Our target: to reach 1,500 meters (about a mile) depth. Drilling this deep is a major challenge when you are drilling into the seafloor, which just [...]

An asteroid impact 100 miles (170 kilometers) off the coast of Maryland would send waves up to 50 feet (15 meters) high onto the shore an hour later and massive flooding would occur three hours after impact, according to a new computer simulation of hypothetical asteroid impacts. The model is the first of its kind and federal agencies have used it to assess potential hazards arising from such impacts in an effort to increase U.S. emergency preparedness, planning and management, the scientists [...]

In Hawaii, a lava flow from Kilauea was nearing residential areas in the northwest portion of Pāhoa on October 27th. The flow front was heading towards a low spot on the Pāhoa Village Road, between Apaʻa St. and the post office. In this photo the flow front was 540 meters (0.3 miles) from Pāhoa Village

This fossil is somewhat rare because it was found at a depth of 60-250 meters underground. The fossil was situated above the coal seam so it might be from the Pennsylvanian Period (late Carboniferous). It was found in Webster County Kentucky USA. The mines there are part of the Eastern Interior Basin. The formations found there are Sturgis, Carbondale, and Tradewater. The limestone layers

Here is a magnified image of a Caecum sp. sea gastropod shell. It was found in 2014 during a diving trip to Key West Florida, USA. The specimen was about 2 km off shore in about 5 meters under the water. I do not think this is a fossil. Viewed under microscope with a 3 mm field of view. Thanks to Kenny for the specimen and Herb for letting me use his microscope. Learn more at these

Since we have already drilled a hole at Site U1440 (approximately 20 meters from where we are now) and collected sediment cores from that hole up until we hit hard rock, we started our second hole in a whole new way. Because this hole will be used to obtain cores from deeper depths we need to 'case' the hole to keep it stable. We also need to be able to re enter it several times. read

The Bite Force Of T. Rex

Ever since the first T.rex skeleton was pulled from the ground, it was known that this animal had an incredibly high bite force (its head was over 1.5 meters long and filled with teeth some 6-13 inches long, of course it did, haha). But the question was just how high? Early estimates put it at about
