Differentiation index from Calypso core GS16-204-22CC-B, Eirik Drift, Labrador Sea

DOI

This dataset shows the relative abundance of the five most important open ocean and sea ice indicator ASVs for the time interval 5–45 kyr b2k in GS16-204-22CC-B, Eirik Drift, Labrador Sea. The open ocean indicator ASVs are identified in the Holocene (5–8 ky b2k); the sea ice indicator ASVs in MIS 2-3 (20–35 ky b2k) of GS16-204-22CC-B. In these calibration windows, the indicator ASVs cannot be used for interpreting the environment. The indicator ASVs were identified in our metabarcoding dataset via the multipatt function of the indicspecies v1.8.0 R package (Cáceres and Legendre, 2009). The full metabarcoding dataset is available from the European Nucleotide Archive repository via accession number PRJEB112075.
