For this week’s “Monday Geology Picture” here’s a shot of a pretty granite boulder that I spotted during a forest hike in the Constantia region of the Cape Town, South Africa. No doubt, this boulder consists of ~550 million year old Cape Granite. There’s no scale in this picture, but the boulder is about 2 meters
Check out this massive pile foundation for a wind turbine at the 402MW Veja Mate offshore wind farm. It weighs over 1,300 tons (2,866 kips) and is 7.8 meters in diameter (25.5 ft) and 82.2 meters long (270 feet). The wind farm will consist of a total of 67 6MW turbines founded on giant monopiles like this. According to Offshore Wind, the Veja Mate OWF is located 95 km northwest from the island of Borkum in the German North Sea. When fully operational in 2018, the farm will produce over 1.6 TWh [...]
This is the first in a series of dispatches from scientists and education officers on the latest expedition of the Schmidt Ocean Institute. by Peter Girguis My name is Peter Girguis, and on behalf of the science party and the Schmidt Ocean Institute I welcome you to our expedition’s blog. We hope that you will join us throughout the entire expedition as we explore some of the most amazing animal
Ginny and Jason search for life... hundreds of meters below the seafloor.
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”.
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
Last month, NASA issued a press release to announce that the Curiosity Rover had reached the “Bagnold dunes” and was preparing to investigate. The image above is from that announcement – the landscape covered is only a few meters
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).
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.
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
If just the West Antarctic Ice Sheet were to melt, it would raise global sea level by 6 meters. That’s more than a theoretical problem. West Antarctica is losing ice mass, and scientists are
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. With the help of
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 [...]
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 [...]

Today marks the start of Earth Science Week – a yearly international event which aims to help the public gain a better understanding and appreciation for the Earth Sciences. The event is promoted by the American Geosciences Institute and the Geological Society of London, amongst others, so be sure to head to their websites to find out more. Our Imaggeo on Monday’s image celebrates Earth Science Week too, as well as the General Assembly 2015 conference theme, A Voyage Through Scales! This [...]
I have mentioned this animal before in a previous posting and about the computer game it is featured in. It is now at its maximum level and appears quite iridescent. It is from the mobile phone game Jurassic World.
This Permian Period reptile like amphibian is a Limnoscelis. It is thought to be a carnivore and grew to a length of about 1.5 meters.
The game is available for free for
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
On Feb. 15, 2013, with no warning, an asteroid 20 meters in diameter and weighing more than the Eiffel Tower plunged into the Earth’s atmosphere over the Russian city of Chelyabinsk at speeds in excess of 19 kilometers per second. … Continue reading

A beautiful image of a forest reflected in a pool of water within a pothole in southern Finland is this Monday’s Imaggeo image and it brought to you by Mira Temmlin, a Finish researcher. The photo illustrates a pothole in the Askola pothole area in southern Finland. The pothole area is situated on the steep slopes next to river Porvoonjoki, approximately 70 kilometers to the northeast from the capital city Helsinki and 30 kilometers to the north from the Gulf of Finland. The potholes are [...]
