We applied metagenomic shotgun sequencing to a sedimentary ancient DNA (sedaDNA) record from the North Pacific (off Kamchatka) covering the last 20,000 years to trace temporal changes in ecosystem composition and food webs. This dataset contains count data before re-sampling for (1) phototrophic bacterial and eukaryotic pelagic families, (2) and eukaryotic benthic families, and (3) a list of families, their grouping into habitat (pelagic/benthic) and trophic status (phototrophic/heterotrophic), the taxonomic group to which the family belongs, the resampled number of read counts used for the formal analysis, links (edges) in the pelagic network, and Spearman correlation coefficients (ρ>0.2) and Benjamini-Hochberg adjusted p-values between families and environmental variables (SSTs and IP25). Associated sequencing data, on which the taxonomic classifications are based on, can be found at the European Nucleotide Archive (ENA) under BIOPROJECT: PRJEB46821.
