Use Case 7: Identify devices that operate via a given method.
  -> Includes whether that method is remote sensing, in-situ sensing, or in-situ sampling.

Rather than consider end results, it may be valuable at times to understand what devices are capable of performing a particular method, e.g., fluorometry, or coring.

Alternatively, one may want to know which devices are immersed in the medium being measured, and which are removed from it.  

(Note: This use case was pursued in the Advancing Domain Vocabularies workshop.  See http://marinemetadata.org/examples/mmihostedwork/ontologieswork/mmiworkshop05/domains/sensors/notes/ for the resulting thought process, vocabulary, and issues.)
