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. By registering your samples, you automatically contribute to building a global catalog of Geoscience samples. |

February 2007: Curators of major sample repositories and museums and Geoinformatics experts discussed the implementation of the IGSN in geological sample curation at a workshop in Boulder, Colorado, jointly organized by SESAR and the National Geophysical Data Center NGDC. 
December 2006: More than 3.5 Million objects from the Deep Sea Drilling Program (DSDP) and Ocean Drilling Program (ODP) - holes, cores, core sections, core samples - have been registered with SESAR and assigned IGSNs. List of IGSNs for each leg can be downloaded
