[IRIS] 8 Hz geophones, vertical and horizontal, available free

[IRIS]

Subject: 8 Hz geophones, vertical and horizontal, available free to a  
good home


Stanford University owns a large number of 8 Hz geophones, as used in  
conjunction with the Seismic Group Recorder (SGR-III) facility in  
many PASSCAL experiments from 1980 to 2001.

We have about 200 "short" strings of 6 modified Mark Products L-10B  
vertical-component geophones (8 Hz) connected in series, with c. 1 m  
cable between each phone.

We also own a larger number of "long" strings of 12 L-10B vertical  
phones, or of 12 horizontal phones, in each case with c. 15 m cable  
between each phone, one string per clip.


These will be disposed of as scrap/landfill on October 1, unless  
anyone claims them first


I can consider offers to take all or any part of our equipment.  You  
would need to pay shipping.

If you know of anyone who would want e.g. single geophones for  
teaching/demonstration purposes, please forward this message.
