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
On May 9th, 2014 the JOIDES Resolution set a new record for it’s deepest set casing, beating the old record by 19 meters (leg 186 hole 1151B)!!! The Siem offshore crew set casing down to 1,087 meters below sea floor (mbsf), that’s about 0.7 miles of casing!
But what is casing?
As a big marine/deep-sea biology nerd, I've been following the recent NOAA Gulf of Mexico Expedition undertaken by the Okeanos Explorer via the live stream on their website. For those who may not be familiar, the Research Vessel (R/V) Okeanos Explorer deploys an ROV (Remotely Operated Vehicle) aka a robot submarine which can deploy to 6000 meters.
The ROV has cameras that basically broadcast
In the 1930′s a fruit company was clearing farmland on the Pacific coast of Costa Rica. During their work hundreds of stone spheres up to two meters in diameter were discovered. They are thought to have been made over 1000 years ago and their makers and the methods used to make them are unknown. It
The chalk cliffs on the Sussex coastline normally retreat at about 3/4 meter per year, but storms in the first quarter of this year have produced several meters of
Just how low can one go? Just how far can people descend in life before they hit bottom? In Death Valley National Park, there is a precise answer: -282 feet, or -85.5 meters at a spot called Badwater. That's also the lowest you can go in North America, but if you look at the big picture, there are seven other places around the world where you can sink even lower:
Earth’s Lowest Elevations
Did you know that there are seven distinct depressions on Earth that are over 100 meters below sea level, and twenty-three that are over 10 meters below sea level and ten more that are at least two meters below sea level? We have a google map that points to ten of these depressions and a
We are getting closer to basaltic basement now but still have a couple of hundred meters to go before we can breath easily.
Covered by more than 4000 meters of water in the South China Sea, deep sea sediments come out to the surface during the drilling. Apparently they are quite uniform and dark, ranging from gray-black to greenish. However, a good close up can reveal some funny colors. Here an example with some psychedelic quartz grains, observed under Polarized light.
Giants of Earth's history still pose a wealth of riddles / Publication in PLOS ONE
Sauropods, the largest land animals in Earth's history, are still
mightily puzzling the scientists. These plant-eating dinosaurs with
their long necks and small heads could reach a height of 10 meters or
more and dominated all other land vertebrates in terms of size. They
could weigh up to
Lived: 77-65 million years ago, in the late Cretaceous.
Size: Roughy 3 tons in weight, and 7 meters long.
Bizarre features: Therizinosaurus had huge, 2.5 meter long arms, and at the end of its fingers, 70cm claws. They were probably used to strip trees of leaves or bark, or
“USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.” Quoted from the USGS press
The velociraptor was a rather mid-sized dinosaur. Usually about 2.07 meters for the adults and weighing up to about 15 kg. fossils of dromaeosaurids have been known to have had feathers. Weird right? Velociraptor have been known to have feathers covering their whole bodies. AND velociraptor has been known to have full covered and developed
The Troodon was a very small dinosaur. Its average height was around 2.4 meters and its average weight around 50 kilograms. The troodon had unusually large eyes (from what we can tell). The troodon has one of the largest brains of any dinosaur group, relative to the tiny body of theirs. The troodon’s cerebrum-to-brain-volume ratio
The resolution is 375 meters on this image. Ctsy. Dan Lindsey at CIRA in Colorado. There was apparently a big jump in lightning around the eye at landfall. More on that here. GOES R will have on-board lightning detection when it launches in a couple of years. This instrument alone is likely to lead to some new discoveries and significant improvements in now-casting and forecasting. A nice loop of the
This photo illustration shows the erosion of the east-Siberian island Muostakh. The blue line marks ist coastal line in the year 1951, the red line presents its status in the year 2012. In the upper right corner one can see an aerial picture of the island's northern tip, taken in the year 2012. At its narrowest point the island is shrinking more than four meters per year.
