Moving Off the Ophiolite Standard

The Galapagos

Another of ma belle soeur's is Barbara (Bobbie) John. Bobbie is a research geologist who teaches at the University of Wyoming. Over the Thanksgiving holiday, she chatted with me about her upcoming cruise. We're not talking kicking back with a Mai Tai on the Lido Deck, and checking out the action in the deep end of the pool. At the end of this quarter, Bobbie's going to head off on a jaunt aboard the Joides Resolution to study the action a good ways down beneath the ocean waves.

Out there on the Cocos Plate, west of the Galapagos there's a V-shaped ridge known as Hess Deep. The Deep is a crack under the ocean. Once aboard the ship, Bobbie and the rest of the gang will be drilling a hole down into Hess Deep, and recovering the rock (which at that point will be known as drill core) that comes back up in the drill rod to see what they've found.

How far will y'all be a' drillin' Bobbie? 

OK...we're drill at approx 4872 m below sea  roughly 15980 feet or nearly 1500 feet deeper than Mt Whitney is above sea level (if that helps).  This depth is likely not totally accurate as we have to find a drill site and then go for it...will keep you updated as we go. 

And why bother?

Because the current model research scientists have of what lies below the ocean crust in the Cocos plate, is based on rocks transported far from their origin onto remote continents, by tectonic forces (plate tectonic uplift). Geologists refer to these ancient assembleges as ophiolites. Ain't that a beautiful name? 

On this trip, the folks on the Joides Resolution want to see the fresh stuff. They are planning to get a more accurate picture of what lies under the ocean right there, right now, in situ

Fairy housing beats ours hands down. The fay folk are the green construction originals when it comes to environmentally 

• Pefectly permeable pavement - no challenge to the aquifer!
• Edible totally organic roofs and walls reduce the cost of transporting food to the home
• High-efficiency, non-fueled solar lighting
• Totally compostable buildings lead to no-waste, no environmental impact

Hawks Ahead - Hiking Edgewood

My Kind of Study Break

A Red-Tail Hawk, I think.

Using my low-level cell phone camera, and was I glad I had it.

I'd been focusing on learning about what triggers mass wasting. She was focusing on finding supper.  I think she missed out on her opportunity, as I came around the corner feet away from her in the grass, wrestling with something small and ground-dwelling.

What a reward for studious effort.
