Jon is, well, he's Jon. He listens to techno while processing data, speaks Russian, and, like any self-respecting born-and-bred Alaskan, wears shorts in December. He also has the wonderful distinction of working with crabs, albeit in the form of years of data, and as such is our next interviewed grad student!
Age: Chronological: 27; mental: 10—just ask Chris [Jon's old room mate, to whom he did this:
I am examining possible recruitment controls for Tanner crab in the eastern Bering Sea region using 2 different methodologies. The first employs generalized least squares (GLS) based regression analyses to compare estimated recruitment to the 30-50 mm carapace width (CW) size class against various biophysical parameters measured in previous years. The second employs regional ocean modeling system (ROMS) hydrodynamic modeling to attempt to model advection and subsequent settling patterns of larval crab, with these then being compared against data on the aforementioned biophysical factors and recruitment index using geostatistical methods present in ArcGIS.

2. As a modeler working with YEARS of data, what is a challenge you’ve had to overcome and how did you do it?
One of the major proposed recruitment controls is wind vector, which drives directionality of Ekman transport. Unfortunately my data for this came in the form of 60 192*94*365 data matrices — just to extract the data in R required learning to look at several 2D arrays and then mentally project those into a 3D matrix to grasp the internal addressing system used by the dataset, which was necessary to subset the specific data that I wanted. For someone used to working primarily with Excel spreadsheets, this was…….painful.
3. You don’t work directly with live crabs, but you have worked at sea and in the field. What’s the craziest thing you’ve seen/done?
Girstle River gigantor mutant wasp thingCraziest thing I’ve seen: in the summer of 2008 I was part of an American team participating in the International Polar Year cruise of the T/S Oshoro Maru, a research and training vessel operated by the University of Hokkaido. On the last night of the cruise one of the Japanese students on board decided to try his hand at deep sea fishing, and, well, to say he caught a big one would be a bit of an understatement—he snagged a full grown humpback whale. It was of course subsequently released. [Blogger's note: The guy was using a pink pixee! True story.]
T/S Oshoru Maru -- don't tell Sea Shepard!
4. You are a scientific diver. How long have you been diving and what inspired you to start?
I’ve been diving since the fall of 2005, and as for what inspired me, well, when I was a kid I was something of a tidepooler and was *very* interested in the various organisms I found. Thing was, I knew I was only seeing a snapshot of their life cycle and that it was not representative of what things were like when the tide was in. Additionally, I was extremely curious about what things were like in the subtidal and deeper regions, and what lived there. Then when I was 8 it happened: the local NBC affiliate began running old episodes of a show produced by Jacques Cousteau and I was introduced to SCUBA, leading about 3 seconds later to a “EUREKA!” moment.
5. What is your favorite piece of crab paraphernalia?
That would be a picture I took last winter of a very large Tanner crab molting.
Jon's Tanner crab molting = AWESOME!
