Established in 2018, the Global Omics Observatory Network (GLOMICON) seeks to create a consolidated, global community of practice focused on the use of comparable molecular and multi-omic (e.g. genomics, metagenomics, metatranscriptomics) methods to both investigate and monitor biodiversity at all scales. Such levels of coordination are greatly needed to provide organisations such as the Global Ocean Observing System (GOOS) consistent data and improved global coverage in support of its Essential Ocean Variables (EOVs).
