I have never looked into this sort of study but how can an analysis of dust
collected at a point on the surface of the Earth be considered reliable ?
How can meteoric dust be distinguished from terrestrial materials -
including synthetic/industrial stuff ?
How long does the dust take to migrate to the surface ?
Does the dust alter along the way ? (oxidize, hydrate )
How is the dust dispersed by the wind ? Would circulation patterns
consistently create an accumulation bias ?
Is it possible to distinguish between "fresh" dust and meteoric dust that
has already been deposited and then re-introduced into the atmosphere by
storms (especially in the southwest US) ?
Does the collecting technique produce a bias as to the type of dust
collected (i.e. silicate vs. metallic) ?
As a teacher looking for interesting projects for students (and me) to do I
would be interested in knowing how productive, expensive, time consuming and
accurate this sort of research would be. And, of course, it would be great
if such a study (by supervised students) could actually contribute to some
scientific endeavor.
An interesting study... I look forward to your future contributions to
meteorobs.
