MARPA advises that samples be registered with an International Geo-Sample Number (IGSN). IGSN’s can be obtained through the System for Earth Sample Registration (SESAR). The SESAR website allows PI’s to produce custom sample data forms based on the type of sample (e.g., core, grab, slab, etc.) and the volume of metadata obtained for that sample.
For assistance in completing the sample registration process, please see SESAR’s help page and consult MARPA’s video tutorials. Detailed PDF walk-throughs of the registration process can be accessed from SESAR’s site and below.
