Dr Mouse's Adventures in Science

I love science and travel and love to talk about both!

What are we doing here?

Ok, I last left you with a map of the general area and photos of boxes in a warehouse.  But what am I actually doing here?

The basics are that I help program dataloggers that are deployed with seismometers.  Others set off controlled explosions that are recorded by the seismometers.  Someone goes to collect the instruments and I help to archive the data.  Rinse and repeat!

Now for more detail:

One of the first things we did after unloading the truck was to organize the warehouse.  We will have two different types of deployments: single component geophones with a single channel datalogger (called a ‘Texan’) and three component high frequency sensors with three channel dataloggers (called RT130s).

The Texans are programmed before being deployed and here are our programming stations:

There are four stations where and we can program 45 Texans/station at a time.  Each batch takes about an hour (remember we have almost 2500 Texans…)

 

The RT130s aren’t programmed as much as the Texans since they will record 24hrs/day.  They do have their own gps clock that we have to train to help make clock-locking faster in the field.  This meant opening 100 boxes and resetting 200 RT130s.  This took a couple of days, but at least we got to be outside…

The actual RT130s are on the table

It can take from 5-20 minutes for the clock to lock

Once we got the warehouse organized and the RT130s prepping, another step was to load fresh batteries into the Texans.  ~2500 Texans, 2 D-cell batteries each, you do the math.  It was time for a battery party!!!

Boxes and boxes of...batteries!

Now, these D-cells are in addition to the 200 larger batteries that will be used for the RT130s.  Those we don’t have to load into any equipment, but they do have to be recharged so they will hopefully last for 7 days in the field.

batteries for the RT130s

Ok…

warehouse – check!

equipment – check!

batteries – check!  check!

What are we missing?  People!  It takes a lot of help to put in this many stations over such a large area of land.  Next post will be about the mostly volunteers who traveled out to southern California to help make this project happen!
