Shreveport Seismometers

The morning started with a pack of donkeys outside Shreveport, LA supervising our data collection.

Why is our battery output only two volts? ...it was a pesky loose connector cable on the solar panel!

Left: The 'stomp test'. Is our CMG-40T seismometer indeed registering waves in the XYZ? (Pictured as the red, green and blue graphs).
Right: a quick look at our three-month span of data.

           

A seismometer data collection station. The silver insulated GMC-40T seismometer itself (recording 0.05-50 Hz frequencies, as opposed to the GMC-40T-1 which records shorter 1-100 Hz signals) is the silver mound buried just to the upper left of the box.

Catching the golden hour at one of our last sites.
