DECODING THE DEEP-SEA

Arctic & Antarctica

Dr Paige Maroni is using novel deep-sea technologies to preserve deep-sea genomes. By preserving deep-sea specimens in situ, we will collect invaluable genetic data, which in turn will be used to illuminate the phylogenies of a myriad of deep-sea species, enriching our understanding of the biodiversity of our oceans, thus uncovering evolutionary dynamics in the world’s largest ecosystem.

This project aims to test this newly designed deep-sea preservation tool, to subsequently sequence the transcriptomes and mitochondrial and/or nuclear genomes of the collected specimens, as well as be the first to implement this type of technology on a portable and repetitive scale. As a result, we aim to produce a highly resolved phylogeny, depicting the evolutionary relationships that exist between collected specimens. This project will build on already collected data, produce peer-reviewed publications, and publicly make collection and genetic data available. This will ensure that this work builds a baseline for future change and adds to the growing body of literature based on deep-sea evolution, diversity, and demography.
