object type
We have modified the original SESAR IGSN list of object type terms for Environmental Systems Science (ESS) samples. Currently, you must use SESAR terms to register samples for IGSNs. Please provide feedback on any additional terms needed, modifications to definitions needed, or terms that should be removed.
