The first step in planning your sampling campaign is to decide how to organize information about your samples, which includes considering file organization and linking or tracking information using unique identifiers. A common way to organize sample data, is to have separate files for locations (project sites), primary samples, and potentially subsamples; each location, sample, and subsample then get a unique identifier (e.g. Location ID, Sample Name). Your locally-unique sample identifiers are called “Sample Name'' in the ESS-DIVE sample ID and metadata reporting format, based on SESAR IGSN. The Sample Name is usually a meaningful code that enables you to organize and track samples within your project (e.g. RockCr001_2021-05-25).
