Results from a short visit to the Florissant Fossil Quarry

As part of my vacation last fall I had an hour or so to kill in my schedule and happened to be passing near Florissant, Co. The town is well known for the Florissant Fossil Beds National Monument which preserves an ancient lake bed from the Eocene that was near a field of volcanoes. The volcanoes would erupt with lots of ash and this would rain onto the lake and the surrounding environment. As the ash settled it would cover anything that happened to be floating on or above the lake surface. [...]

Before I started on my adventure in Oklahoma I landed in Dallas and drove north to a site that a good friend had suggested I visit. It was a creek that exposed the Duck Creek formation (Cretaceous, Albian stage) in a couple of spots. Having never collected in Texas before, but seeing plenty of field reports from those who had, I knew the Duck Creek formation should produce some nice fossils. I was not wrong. I found four specimens of the ammonite Mortoniceras sp. washed out in the creek bed. [...]

Evolving Geographic Information System: OpenWebGIS plans & its crowdfunding campaign

Perhaps you have already used in your work OpenWebGIS or just have seen it or read about it. Due to this system exists since 2014. But we will describe OpenWebGIS briefly. It is an open source online/offline geographic information system for work in web browser or mobile app. Since its foundation, a great number of users have benefited from using this system functions. The site and the blog have been visited tens of thousands of times. Over this time the system was worth mentioning in [...]

The British Geological Survey just came out with a new video on Siccar Point, featuring some excellent drone video of the site (in very good weather!). In addition to the unconformity, one of the things you will appreciate about the video is an excellent end-on view of a plunging synform exposed just above waterline: You’ll get a much better sense of its shape by enjoying the motion of the drone’s

We have finally arrived at our next site, the Agulhas plateau.  After two days of driving through waves that just kablooshed all over the deck, up the moonpool, and over the bow, we are now gently rolling and once again laying down pipe to the ocean floor.  Our crew is fearless - Bobby climbs nearly 200m to do his job.  What I wouldn't give to see the view from up

With the pylon at Aust coming up close to its 50th anniversary it is time that National Grid and Trant Engineering Limited give the concrete pillars it is stood upon some major renovation. As part of these works, that will continue throughout 2016, the concrete causeway that leads from the old ferry crossing down to the pylon will be in constant use. Over many years soil and clay have accumulated at the base of the adjacent cliffs forming a huge bank pushing against the causeway. It was [...]

This is a wonderful tale of geotechnical engineering in the marsh lands of Toronto, by the Humber River, site of slope failures and fish ladders. This is life done right.  I applaud the geotechnical engineer.  Everywhere they are going with heavy equipment they have cloth and a foot or more of high-grade Granular A.  There will be no disturbance of the ground, and the stuff is easy to

Over the transit, during our medical evacuation, the scientists on board were able to catch up on a bit of their work. Before we left the site the core was coming up on deck fast a furious. This break in fresh core allowed them to continue analyzing the core we had already collected. We even used the time for our first sampling party.  read

Building after hit by landslide, from CNN.com here        On Sunday, noon local time, a landslide (mudflow?) slammed into an industrial park burying, according to recent CNN reports, 22 buildings according to the CNN report, 33 buildings according to a NYTimes.com report. The site appears to be fairly close to Hong Kong on the north side, and in an area of steep hills. Accounts are obviously very preliminary at this time. Three buildings housed workers. [...]

The coolest way to visualise how planets work

It’s not always easy visualising the complex processes which operate on planet Earth. Even more difficult, at least for me, is explaining them to others. That’s why I’m always on the look out for tools that might just help me with that and which I can share with others too. Enter the NASA Visualisation Explorer, and the Scientific Visualization Studio (SVS), which I came across recently. The first of the two is a cool little app which can you get straight on your mobile [...]

We're coring our last hole of our last site of our last week of expedition 356. Everyone's a little tired and frazzled after two months at sea, away from their family and friends, with only the Pet Wall for company. And pretty soon we'll be putting in at Darwin, celebrating, and then going our separate ways. This might seem like an ending, but for the scientists, this is only the beginning of the expedition. These two months at sea [...]

A helideckload of fun!

We've finished site U1462, there's no core coming up, and we haven't seen land or had a weekend for six weeks. The six week point is famous for being a bit of a slump in every expedition, as all that time at sea starts to catch up with everyone. So to keep everyone's spirits up and stave off cabin fever, our staff-scientist Kara arranged some silliness with "Feats of Strength" on the helideck. It was all terribly unscientific. Read on!

The JR has pulled into site U1462, and while we wait for the first cores to come up, the scientists get a tour of the parts of the ships we normally don't get to see. For most of the expedition, we live and work near the bow (front) of the ship, in the laboratories, accommodation, mess hall, and rec areas. So let's explore the noisy world of heavy marine industry! read

For those of you who have not been following our location through our interactive map (why not??!!?!), we’ve moved to our “expected 3rd” site U1461! I say “expected 3rd” because site U1459 was an alternate to U1458 – and come on, they’re practically on top of each other on the map! (If you couldn’t tell from the map, U1458 is the red star beneath the U1459 orange star – they are, in fact, only 1 nautical mile apart [...]

We’ve arrived at site 4, and are making great progress, recovering about 40 metres of sediment an hour! Though this site seems relatively easy to core, it presents two interesting challenges. First, the sediment so far has a VERY strong smell of rotten eggs. Secondly, we’re drilling right in the middle of the Carnarvon Basin, the most productive petroleum field in Australia. This makes things tricky. read
