Hi All,

OK, as promised is the updated message direct from Bob Hutt.  Please
contact him if you have any furhter questions.

>seismometers,
>more explanation is necessary:
>
>NOTE THAT THESE SEISMOMETERS ARE VERY DEFINITELY NOT SUITABLE FOR THE AMATEUR
>SEISMOLOGIST OR HIGH SCHOOL.  THEY ARE EXPENSIVE TO DEPLOY AND OPERATE, 
>AND REQUIRE
>SPECIAL HANDLING EQUIPMENT.  THEY ARE THEREFORE NOT QUITE "FREE."
>
>1.  USGS/ASL is not in a position to "pack up and ship" any of these units 
>to anyone.
>You must come pick them up yourself.  There are no shipping containers 
>available.  They
>may be transported (very carefully) in the back of a van or a truck.  Each 
>unit weighs
>about 150 lbs and is 5.5 inches in diameter and 6 feet 
>long.  Accelerations greater than
>about 2G may destroy them.
>
>2.  Special handling equipment is required:  Test Set/Controller for 
>installation (we
>only have 6); winch and mast assembly (we have none); a special 
>(expensive) cable made
>both for lifting and signal hookup (we have none); and a borehole to put 
>them in.  All
>the special equipment would have to be purchased from Geotech Instruments 
>LLC:

>3.  These seismometers do not come with any recording equipment of any 
>kind.  They are
>only the transducer that converts ground motion into electrical signals.
>
>4.  We will not be ready for anyone to pick up any seismometers this 
>week.  They are
>currently on Kirtland AFB and are inaccessible to the public.  We will 
>make them publicly
>accessible for pickup by May 7, 2001, at our warehouse near the airport in 
>Albuquerque.
>Do not plan on picking any up before that date.
>
>5.  Limited list of Specifications:  May be installed at up to 1,000 feet 
>depth, with
>proper cable and connector.  Power:  22-28 VDC, approx. 5 
>watts.  Three-axis (vertical
>and two orthogonal horizontals).  Amplitude response from each 
>axis:  5,600 v/m/s/s from
>4.2 Hz to 3 sec period, then increasing (6 db/oct) to peak of 126,000 
>v/m/s/s at 80 sec
>period, then decreasing at 6 db/oct at longer periods.  Falls of at 12 
>db/oct at
>frequencies higher than 4.2 Hz.  Suitable for teleseismic work.  More 
>specifications may
>be obtained from Geotech Instruments.
>
>6.  Only about 4 of the ~40 seismometers have been tested and found to be 
>partially
>operational (some channels very noisy or not working, other channels 
>fairly good).  The
>condition of the other 36 instruments is unknown, although they were 
>supposedly working
>when un-installed 2-3 years ago from foreign locations.

>For those of you who have contacted USGS/ASL so far, please make contact 
>again and let us
>know if you are still interested.
