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.
The science party and staff of Exp. 346 worked amazingly hard and collected 6,135 meters of core in just 6 weeks. Wow! That wrapped up the last expedition of the Integrated Ocean Drilling program. As of October 1, the program is now called the International Ocean Discovery Program (still IODP!) and began its next phase.
This pictures show a dinosaur replica of an Ankylosaurus. The model is about 5 meters in length. Its name means "fused lizard" which relates to the armored connected plates on its body. Dinosaurs like this existed about 70 million years ago in the Cretaceous Period. They were found in what is modern day Montana, USA and Alberta, Canada.When these pictures were taken the model was on display at Cincinnati Museum of Natural History and Science as of August
A major earthquake that hit a remote part of western Pakistan killing at least 200 people has also created a new island just off the country's southern coast. From the United States Geological Survey - 7.7 magnitude quake struck 145 miles southeast of Dalbandin in Pakistan's quake-prone province of Baluchistan, which borders Iran. The earthquake was so powerful that it caused the seabed to rise and create a small, mud volcano island about 600 meters off Pakistan's Gwadar coastline in [...]
Sakurijima volcano, a large stratovolcano located within the Aira Caldera, has had its nearly 500th eruption of 2013, and this one has shattered some records. A massive gas and ash plume rose above the volcano today, reaching 16,000 ft or more (5,000+ meters) into the sky. Ash rained down on nearby towns and people are using rags and masks to breathe if they venture outside. Video footage showed a large explosion of dark ash, followed by a large plume of grey ash rising far above the [...]
We’ve now arrived at our first site on Expedition 346 and the drillers are beginning to assemble and lower the drill pipe, which when completed will dangle nearly 3400 meters beneath the ship before even touching the mud of the sea floor that we came to collect. Yesterday we passed through the Tsugaru Strait that separates the main Japanese islands of Honshu and Hokkaido.
Archaeologist Anya Shetler cleans an inscription below an ancient stucco frieze recently unearthed in the buried Maya city of Holmul in the Peten region of Guatemala. Sunlight from a tunnel entrance highlights the carved legs of a ruler sitting atop the head of a Maya mountain spirit.
The enormous frieze—which measures 26 feet by nearly 7 feet (8 meters by 2 meters)—depicts human
Japan on Tuesday unveiled its biggest warship since World War II, a huge flat-top destroyer that has raised eyebrows in China and elsewhere because it bears a strong resemblance to a conventional aircraft carrier.
The ship, which has a flight deck that is nearly 250 meters (820 feet) long, is designed to carry up to 14 helicopters. Japanese officials say it will be used in national
ksl.com Mexican paleontologists say they have uncovered 50 vertebrae believed to be a full dinosaur tail in the northern desert of Coahuila state. The National Institute of Anthropology and History says the tail is about 15 feet (5 meters) long and resembles that of a hadrosaur or crested duckbill dinosaur. READ MORE MORE INFO
A great temple to the god Amon was built at Karnak in Upper Egypt around c. 1785. It is from Amon that we get his cephalopod namesake, the ammonites and also the name origin for the compound ammonia or NH3.Ammonites were a group of hugely successful aquatic molluscs that looked like the still extant Nautilus, a coiled shellfish that lives off the southern coast of Asia.While the Nautilus lived on, ammonites graced our waters from around 400 million years ago until the end of the Cretaceous, 65 [...]
Since drilling operations began on June 4th, we started looking at sediment samples recovered from approximately 4,000 m water depth in the Gulf of Alaska. After almost two weeks of drilling, we have recovered several hundred meters of sediment, which will be used to reconstruct the environmental conditions of the northeastern Pacific and the adjacent land during the last 4 million years.
At ~428 meters below sea level, the Dead Sea is considered the lowest point on Earth, and is suitably named for its high salinity content that does not support marine life. Currently, the Dead Sea is shrinking as a result of mining for raw materials and the loss of fresh water inflow from the diversion
The bottom line…the SCIMPI deployment was a success and there many very happy and relieved people. Sitting on the ocean floor this morning is the top 18 meters of SCIMPI that will be revisited in about three weeks and connected to the Neptune Canada network. The entire process had its hiccups.
