Modeling media research–the fine color coded fraction.

Modeling media research–the fine color coded fraction.

We’re continuing our research on low density modeling media.  The mix we usually use tapers out at around 0.5mm on the fine end, but clearly adding smaller particles has a big effect on behavior in movable bed models.  This fraction fills the...

GSA in Portland Sunday

GSA in Portland Sunday

Wow, what a day. It began very early, with a couple hundred geologists waiting at the Pioneer Square stop for a train that took an hour to arrive; with a talk at 11, I had plenty of slack, but others had to scramble for cabs. Somebody forgot that not many people want...

GSA in Portland

I leave tomorrow for Portland and GSA. BrianR at Clastic Detritus has a thorough set of links, including info on a geobloggers get together Monday night. We’ll have a booth there with an Emriver Em2. We’re all pretty psyched–we expect to see a lot of...

A landmark paper in physical modeling.

A landmark paper in physical modeling.

A groundbreaking physical modeling study was published this week in PNAS (subscription required). NSF has a press release here. Christian Braudrick and others at EPS-Berkeley used a 17m flume filled with a mix of lithic and plastic particles to achieve what they call...

Cara off to RRNW, more media work.

Cara off to RRNW, more media work.

We worked on modeling media issues this week, this time on methods to wash it to remove dust and other debris. Here Cara and Jesse agitate a batch. The street value of the exotic color-coded-by-size media in the buckets you see here beside an Em4 box is about $6,000....
