SESAR sample registration is unavailable while we complete important system maintenance.  We will be back up soon.

SESAR is a centralized registry that provides and administers unique identifiers for Geoscience samples - the International Geo Sample Number IGSN.

Use of the IGSN prevents ambiguity by systematizing sample designation and ensures that all information associated with a sample is preserved for accessibility on a global scale.
