Abstract
The MetaZooGene Atlas and Database (MZGdb; https://metazoogene.org/mzgdb/ ) is an open-access data and metadata portal synchronized with the NCBI GenBank and BOLD data repositories. The MZGdb includes sequences for genes used for the classification and identification of marine organisms based on DNA barcoding and metabarcoding. The focus of the MZGdb is biodiversity of marine ecosystems, including phytoplankton and microbes, zooplankton and invertebrates, fish, and other marine vertebrates (pinnipeds, cetaceans, and sea turtles). DNA sequences currently included are mitochondrial cytochrome oxidase I (COI), 12S, and 16S rRNA, and nuclear 18S and 28S rRNA. The MZGdb provides data and mapping tools for assembling and downloading compilations of reference sequence data that are specific to selected genes, taxonomic groups, and/or ocean regions. An additional feature of the MZGdb is the Atlas which summarizes data coverage and proportional completeness based on statistics of species with available sequences versus species commonly found in each ocean region.This chapter is a collaborative effort of the Scientific Committee for Ocean Research (SCOR) Working Group WG157: MetaZooGene: Toward a new global view of marine zooplankton biodiversity based on DNA metabarcoding and reference DNA sequence databases ( https://metazoogene.org ).
