This last week has been a busy one-made even more momentous with all of the very AMAZING observations made by this last leg of the Okeanos Explorer as it explores various seamounts and other sites in the Marianas Islands! A whole bunch of information on the geological setting and the various study areas can be found on their website here.  The entire mission overview can be found on

As many of you picked up on last week, I've been busy working on starfish at Museum Victoria in Melbourne working with my colleague Dr. Tim O'Hara, one of the world's leading authorities on ophiuroids! aka the brittle stars and basket stars! He's had a BUNCH of big research news drop lately (here's the link to last week) While talking to Dr. O'Hara he informed me of of some neat, NEW

Trace fossils in the Massanutten Sandstone

Over the weekend, my wife and I took a walk with our son at the Storybrook Trail, an accessible trail with a fine overlook to the east over the Page Valley. There, the Massanutten Sandstone shows a bunch of big beefy trace fossils at this site: both bedding-parallel (Arthophycus-like) and bedding-perpendicular (Skolithos-like) traces. Here’s Bax on a photogenic slab of the quartz arenite, showing the inch-wide bioturbation: A short distance

We traveled to Cape Evensen, which is an extra site that we added to our trip. Because we were so far ahead of schedule, we got permission to go even farther south to sample in a small gap in our overall gradient. Cape Evensen is at 66°S, so just below the Antarctic Circle.The weather was nice enough while we were there. Since it had snowed the day before, though, we found that it was difficult to find any sampling sites. We saw moss in several locations, but not in large enough patches to [...]

We got snowed-out at our next field site, so we can’t do the field work today that we had planned. It snowed most of last night around the Berthelot Islands, so any potential ground we wanted to sample is covered by about 4 inches of snow. We walked around a bit to see if we could find anything, but all we could identify through the snow was moss. We’re heading further south to our final site, with the hopes that when we pass back by Berthelot on our way north, the snow will have melted or [...]

Another week and another bunch of deep-sea Okeanos dives in the French Frigate/Hawaiian Islands region! One thing I noticed while reviewing the recent dives and those from last year was just how much COLOR you see in the deep-sea.. black, white, ORANGE... and purple! Purple is of course, the color of kings! In Chinese painting, purple represents the harmony of the universe because it

biomodel: generic gorgonopsid

So I’m modeling a gorgonopsid for Christian Kammerer. A bunch of them, actually. And I’ve started with a biomechanical model. Not a skeleton. Skeletons are a lot of work, but there are more convincing arguments to come up with an abstracted model of the skeleton… we often do not have skeletons, or they have to

fieldwork and your period

A recent post at Dynamic ecology referenced a long twitter discussion of menstruating in the field. What amused/horrified me was all the suggestions that we (the ladies) should just get an IUD or take a whole bunch of hormones or something to banish our periods altogether. What a strange overreaction. I've been getting my period since I was 13, and it's really not a big deal. On days where

So I look at my blog today, and a bunch of stuff looked different. I don't know how or why because I haven't touched the "layout" button in a long time, but since the arrangement looked terrible, I made some tweaks, mainly trying to make the links easier to read. Anyway, we will return to our regular programming as soon as possible. The picture is a New Mexico teaser, a sneak peek at a

When snail shells are deposited in a bunch of sediment, they serve as tiny architectural elements, with a “roof” that protects their interiors. Any sediment mixed into the shell’s interior will settle out (more or less horizontally), and then there will be empty space (filled with water, probably) above that. As burial proceeds and diagenesis begins, that pore space may be filled with a mineral deposit, such as sparry calcite.

This is on the main line, a highly directional M4.5, which has been registered as a 5.4 in the direction of the hammer.  We should expect a bunch of these, and this will be the #2 attempt on the 10-chamber Russian Roulette gun. Once we have the 4 or 5 major quakes, then there will a slow diffusion of the strain field, causing many quakes in the OK mechanism, and possibly tickling New

I shouldn't be writing this, but here we go again.  This is a deep normal earthquake with the 'hammer' going into the Earth.  That's why it is being identified as 6-ish on the other side of the world.  A bunch of these on the fault, and I'm going to issue Alert #2.  :)  As I was saying on g+, I estimate we can go up to 10 'false' alarms.  A random 'Italian Cluster' has a 1 in 100 chance of

My colleague Martin Schmidt of the McDonogh School, who I know through the National Association of Geoscience Teachers eastern section, recently shared a bunch of fold photos with me. They have a “dated” feel because they were originally shot on slide film, but the folds themselves of course are timeless. I’ll be featuring a bunch of them here in the weeks to come. Here’s a scene Martin captured in northern

Here’s the last post (at least for now) in the Fighting Apatosaur Art series — and we’re back to Brian Engh, who we started with. Early in the process of putting together artwork to illustrate our apatosaur neck combat hypothesis, Brian tried out a whole bunch of outlandish concepts. Here are two that he showed

So, that was a big gap. I got hit with a whole bunch of issues (personal and professional) that sucked up all my time, and then my posting fell by the wayside when my newfangled "write on weekends, post on weekdays" schedule hit a snag. However, I do have a big pile of post-it notes with blog post ideas, which I kept accumulating in my posting absence. Let's see how it

For one, a bunch of it was underwater, the Strait of Juan de Fuca, the Strait of Georgia, the Puget Sound, bodies of water collectively known as the Salish Sea. Second, we had reached the southern reach of the vast

Another gem from the Grinnell Glacier cirque: Zooming in on the contact, showing the concentrically-zoned ooids: Near the tip of the flame structure (?), I noted alignment of longer platy / flaky components within the oolitic layer: This looks like a loading structure – soft sediment deformation due to a density inversion – perhaps when some high-energy event (a storm?) dumped a bunch of relatively coarse ooids atop some squishy

July 14, 2015 is going to be an important date in the history book of space exploration. At about 7:50 AM Tuesday, New York time,  the New Horizons probe will pass about 12,500 km from Pluto, and the most sophisticated set of instruments ever put in deep space will record high resolution images of the dwarf planet. Images of Pluto will be recorded in visible and infrared light, while other
