Trials of the ADCP

-
One of our projects key piece's of equipment is an ADCP which stands for Acoustic Doppler Current Profiler. Basically its a $30k piece of equipment that uses sound waves to determine the velocity profile of a stream. Unfortunately the version we have is really designed to be mounted on a boat and used in deeper waters so we were unable to get it to work yesterday. I did get to use some surveying equipment to plot points along the logjam and stream bed though, which was cool. Today was a reading day for me, mainly documentation on the ADCP model we have and the one designed more for our project type. Tomorrow its back to the field to see if my new knowledge helps us collect any usable data.
This evening there was an HJ Andrews potluck which was fun and a nice change from the basic cooking I've been doing. I got to talk with some of the long term workers as well as members of the other crews stationed here. I brought a basic vegetable platter, but other people got more creative including lasagna, fish patties, and beet salad. Tomorrow evening we drive to Corvallis to stay in the dorms in preparation for our series of Friday meetings and seminars. Then its the weekend, the current plan is some sort of camping though the logistics are sketchy.

Zu Hause und in der Stadt

 These photos don't quite fit in with the weekend excursions cataloged in other posts but I wanted to share them nonetheless. First more bread! This is Sportler-Brot which is so far my favorite. Next up is Bio Roggen Pur or Rye bread. It is more mild than the rye I've had before. This is Dinkel Chia, it was good but didn't stand out particularly. Some stores stick a paper label directly on the loaf which is the white stuff in this picture. Finally we have Familien Brot, another whole wheat loaf. It was longer than the others so perhaps that's where it gets the name. I'm not just eating sandwiches though. A couple weeks ago I attempted Schwäbische Linsen mit Spätzle, which is a South German lentil dish served with traditional noodles. Here's the work in progress. I used store bought dried Spätzle to make things easier and it turned out quite well. On the sightseeing front here's a view across the Isar of St. Maximilian. The ducks in the river originally attra

Deutsches Museum

 The weather forecast for Saturday of the long easter weekend called for rain so I booked a ticket for the Deutsches Museum  which is billed as the largest science and technology museum in the world. It does have its own island which you may remember as the location for my covid test to break quarantine. Like the Nymphenburg palace grounds the Deutsches Museum also has an app which I started out by promptly ignoring and checking out the Mine exhibit.  As you can see the exhibit is styled as a replica cave with scale replicas representing different types of mining. They did keep things to scale as seen by this doorway. I appreciated the coal mining section, having visited an actual coal mine in Pennsylvania. The exhibit did an excellent job capturing the claustrophobia (though perhaps my photography did not). The machine room representing more modern mines even smelled like a machine shop which I assume is realistic. Once out of the mines I opted to actually follow the Apps suggested hi

The Final Countdown

-
I doubt anyone is still reading this, but I need a break from Mathematica so I thought I'd try writing some plain English for a change. We've been in Corvallis now for 4 weeks, and aside from one trip back to Quartz Creek I've been doing my work here, either in the library or memorial union. Earlier this week the other two members of my group Will and Ginger went out to Crab-Tree Creek on the Santiam to finish the last of our data gathering. I opted not to go for two main reasons, one the StreamPro (The ADCP actually designed for shallow water) can be easily operated by two people, and two I already had plenty of work to do. For the last 4 weeks I've been using Mathematica to visualize and analyze our data. It may not be the best tool for the job, but I know how to use it. Essentially what I do is read in text files of data from WinRiver (the program that comes with the ADCP), process them into a usable format, then use them to make pretty pictures. Aside from work I
