In this study, we provide the first taxonomic overview of the modern and ancient marine bacterial and eukaryotic communities of the Totten Glacier region, East Antarctica, using a combination of 16S and 18S rRNA amplicon sequencing (modern DNA) and shotgun metagenomic (sedimentary ancient DNA, sedaDNA) analyses, respectively.

Our data show considerable differences between eukaryote and bacterial signals detected via DNA analyses in the water column vs. the sediments. Organisms that are well represented in deeper waters appear are to have a higher likelihood of becoming preserved in the sediments. The study provides the first assessment of DNA transfer from ocean waters to sediments, while also providing a broad overview of the biological communities occurring in the climatically important Totten Glacier region.
