Dr Mouse's Adventures in Science

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

iMUSH-putting the pieces together

Leave a comment

Volunteers+texan dataloggers+geophones=data is the basic equation, but the pieces are so much more complex than just that.

Each station is comprised of one Reftek 125A (aka a Texan) datalogger (in the bag) with 2 D-cell batteries inside for power, as well as one 4.5Hz Geospace geophone (the orange contraption).

 

 

 

 

 

We dig a hole, usually using a pickaxe since the hole is more of a small trench,

and then plant the geophone into the ground using its spike.  Next bury the Texan (wrapped in the plastic) next to it (after they are connected to each other of course!)

We try to hide the stations, but not so well that we can't find them again. Often a metal detector comes to the rescue when that happens

We cover the entire instrumentation package up and viola!  An active source seismic station waiting for seismic waves to roll on in!

Above is a rough shot-gather of a planned man-made explosion that was detonated near Woodland, WA. It was about the size of a 2.2 magnitude earthquake and above you can see the seismic arrivals and some of our Texan stations.
