Biogeochemistry and Domoic Acid Transcription Data From Jones Sound and Nares Strait, 2019, 2021

This dataset is from August 2019 and August 2021. Biogeochemical data in this dataset has been published previously in other formats in Bhatia et al. (2021), and White et al. (2025), but is recompiled to be paired with transcript data reported. New data in this study includes domoic acid transcriptional data. This data supports the publication, "Molecular evidence of domoic acid production in the High Arctic Qikiqtaaluk Region of Inuit Nunangat" White et al., (2026).
