I wonder if it can double as a visual seismograph?

I wonder if wind speed measurements from this instrument need to be recalibrated because there seems to be a permanent kink in the thread and the upper part is rigid.
If a particular amount of deflection has been calibrated to a particular wind speed during Earth based measurements, those measurements I would think need to
be redone with a similarly bent and frozen thread.

Any gueses as to what happened to the thread? Moisture froze it solid? Just got bent and stuck during the long cruise?

Ha ha, so funny laugh.gif

A little bit off topic, there was a very simple seismograph that the ancient Chinese used here http://geology.about.com/library/weekly/aa070598.htm
