PI(s):
Kerstin A. Lehnert Registry to assign and administer the International Geo Sample Number (IGSN) as a unique identifier for Earth samples.
SESAR is a centralized registry that provides and administers unique identifiers for Geoscience samples - the International Geo Sample Number IGSN.
Use of the IGSN will help to avoid ambiguity, systematize sample designation, and ensure that all information associated with a sample is preserved and accessible on a global scale.
Unique sample identification will aid the preservation and curation of samples, and facilitate sharing of samples and sample-based data.
