Description

DNA data underlying the paper 'From the Surface Ocean to the Seafloor: Linking Modern and Paleo-genetics at the Sabrina Coast, East Antarctica (IN2017_V01)' by Armbrecht et al. (https://doi.org/10.1029/2022JG007252). In this study, a modern and a paleo-genomics approach to investigate vertical profiles of marine organisms (bacteria and eukaryotes) through the water column and underlying sediments were conducted at three sampling stations off the Sabrina Coast, East Antarctica. Water and sediment samples were collected during the “Sabrina Seafloor Survey” (IN2017_V01) and represent the surface waters, chlorophyll maximum depth, bottom waters, and several depths below the seafloor. Conductivity–temperature–depth (CTD) data, seawater samples, and sediment cores (Kasten Cores [KCs]) were collected during the RV Investigator voyage IN2017_V01 (“Sabrina Seafloor Survey”) between January and March 2017. A combination of 16S and 18S rRNA amplicon sequencing (modern DNA) and shotgun metagenomics (sedimentary ancient DNA, sedaDNA) was used.

Data were extracted from supporting information file (https://agupubs.onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1029%2F2022JG007252&file=2022JG007252-sup-0001-Supporting+Information+SI-S01.pdf) provided with the research paper (https://doi.org/10.1029/2022JG007252).

DNA dataset were downloaded from Armbrecht, L. & Focardi, A. (2022), Totten Glacier ocean & sediment DNA (IN2017_V01). University of Tasmania Research Data Portal [Dataset], https://dx.doi.org/10.25959/hwk8-cc81. All read counts, sequence id for Bacteria, Archaea and Eukaryota identified using sedaDNA at KC02, KC06, KC14 are extracted at the lowest identified taxonomic level from MEGAN (CE v.6.24.23).
