Platform/Measurement: All data
	What level data: (raw,a0,a1,b1,c1 etc): All

    What location was the data collected at: Meeker

    Period of time in question
 	Begin Date  95/03/01   Time   00:00    (GMT)
 	End Date    95/03/10   Time   19:54    (GMT)

 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 ___  incorrect                         ___  Only some data fields affected
 ___  wrong calibration
 ___  others 

 Discussion of Problem:

Mentors discovered signal cable problems that forced all data channels to
be non-functional. The problems were corrected and the platform reinitialized.
The data logger PROM was upgraded to the lateset Version 13.

Other observations/measurements impacted by this problem:


Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
