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 [...]
The Sauropods such as Apatosaurus and Brachiosaurus were Massive animals.Known for almost 190 years they have fascinated us.
These are the titans of the dinosaurs.Reaching lengths of around 42 meters and weighing up to 90 tons.Now how did they get so big you may ask?There are many reasons why here are a few of them.
A few days ago we broke the scientific ocean drilling record for the deepest APC core ever obtained (687.4 meters below the seafloor!). But what is APC? And how does it differ from other coring systems?
Since last update of activity in Bárðarbunga volcano there have not been major changes in Holuhraun eruption. The lava lake in the crater has lowered by several meters based on pictures from Holuhraun today. Large cliffs have formed … Continue reading
The JOIDES resolution is designed to perform deep sea drilling: even in water depths of 9000 meters (27,000 ft), the JR can drill 1000 meters (3000 ft) into the bottom of the sea.
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
The landslide of Köfels (named after a small village in Tyrol) is one of the largest recognized landslides in the Alps – large enough to dam up a 92 meters (300 feet) deep prehistoric lake and divide in two the valley of Ötz. Wood fragments discovered during the construction of a gallery in the landslide
This is one beautiful and shiny fossil! It appears to be a Strobeus pyrite gastropod fossil. It was found in a coal mine at a depth of 60-250 meters. More pictures below show some more specimens that were found.

This pyrite gastropod fossil has well defined ridges that make it easier to identify. It appears to be a Bellerophon. It was found in a coal mine at a depth of 60-250 meters.

This gastropod fossil is interesting as it pyrite embedded in a dark shale. It appears to be a Trepospira. It was found in a coal mine at a depth of 60-250 meters.

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
Elasmosaurus vs Cymbospondylus
Elasmosaurus- thin plate lizard

Sharp teeth and size
Long neck and few weapons
Cymbospondylus- boat spine
10 meters long and 2.5 tons
Teeth, more powerful jaws, speed, and agility
Smaller of two fighters and light sensitive eyes
Setting- The deep ocean
An Elasmosaurus is hunting. Schools of fish are becoming rare and the [...]
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.

I took this image in 2005, when I was working up a geologic history of the C&O Canal National Historical Park. It’s a vein of quartz, gracefully folded within the Catoctin Formation. The exposure is along the railroad tracks at Point of Rocks, Maryland, easternmost extent of the Blue Ridge province on the north shore of the Potomac River. The Culpeper Basin begins about 100 meters to the east of

Continuing my brief series of things my students didn't see on Vancouver Island during our Northern Convergence tour of Canada, we reach a place my students did in fact "see", as in we were there and looking around, but the students didn't see what we saw. Malahat Summit is 352 meters above sea level, about 1,155 feet, and is
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.
Super-typhoon Neoguri, first super-typhoon of 2014imaged on July 6 (?) by NOAA/EPAThree inches of rain PER HOUR??? I wonder for how many hours!! Waves up to 14 meters (45')? I have friends on Okinawa and wish them well (and also asked them to send a first hand report!) The storm is expected to work its way up to mainland Japan by Wednesday. The highest danger is for Miyako-jima, in the center of the archipelago. As I write this (Monday a.m. PDT) gusts of up to 270 [...]
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
