DECODING THE DEEP-SEA

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.

Dr Paige Maroni is a Postdoctoral Research Fellow from the University of Western Australia (UWA). Maroni received her Ph.D. from UWA in 2023 and her undergraduate degree and first-class Honors degree from Murdoch University in 2016 and 2017, respectively. Dr Paige Maroni just recently completed an expedition with the Schmitz Ocean Institute to explore The Nazca Ridge. and discovered over 100 new species. The exploration was live streamed around the world.

Project Aims:

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.

To support this project YFS is seeking yachts cruising the northern hemisphere in June- September Summer and Southern Antarctica from November to March. Private vessels & cruise ships with spare berths travelling to and from these locations make ideal research vessels for Dr Paige to carry out her research.
