Dataset: Spatiotemporal patterns of salmon winter habitat usage in the Northeast Pacific uncovered by environmental DNA

Amplicon sequence variant (asv) dataset from multi amplicon metabarcoding
environmental DNA analysis from the International Year of the Salmon
Signature expedition to the Northeast Pacific in Feb/Mar 2022. A table of
all asv generated in the study is provided  in ASV.csv, broken
down by amplicon and sample and listing the occurance of said asv in said
sample. Further, total reads per amplicon/sample bin are recorded as well
as a taxonomic assignment. Note that this data is provided prior to
filtering, e.g. "Homo sapiens" reads are abundant and should be
considered contamination. The metadata to sampling stations is provided in
the sample_metadata.csv which contains the date, lat/long, as well as
detailed environmental metadata associated with the sample. Refer to Deeg
et al. "Spatiotemporal patterns of salmon winter habitat usage in the
Northeast Pacific uncovered by environmental DNA" ICES Journal of
Marine Science 2025 (https://doi.org/10.1093/icesjms/fsaf104) for
detailed information on sample collection, sequencing and bioinformatic
processing.
