EarthCube – iSamples Sample Management Training Module
I. Ra:onaleforsamplemanagementStatementofPhilosophy:
Physical samples are the basis for field-based geologic and petrologic study. To the investigator, samples represent the ability to make laboratory observations that are impossible in situ, and they should be treated as the sensitive “currency” of geology.
Time and effort managing a growing collection of samples means preserving this currency, and investing in its potential in the future. As much as scientific inquiry is built upon the past discoveries in our field, our investigative power is greatly strengthened by being able to return to the original source of our detailed analyses—our samples. With the swift advance of analytical power it should be clear that the future holds new ways of exploring information stored in our sample collections.
Samples collected as part of publicly funded research belong, in part to the public, and therefore should be ultimately available.
