Amplicon sequence variants (ASVs) and taxonomy of Pseudo-nitzschia spp. from Narragansett Bay in Rhode Island, USA and the Northeast U.S. Shelf (NES-LTER transect) from 2018-2023

This dataset includes amplicon sequence variants (ASVs) representing species of the harmful algal bloom diatom genus Pseudo-nitzschia that were sampled from various sites in Narragansett Bay, Rhode Island, including the Narragansett Bay Long Term Plankton Time Series site, and various stations along the Northeast U.S. Shelf Long Term Ecological Research program transect. These data correspond to an analysis of Pseudo-nitzschia species composition and domoic acid toxin production during winters and summers from 2018-2023 in Narragansett Bay and the Northeast U.S. Shelf, which was prepared for submission to Harmful Algae (Roche, et al.). ASVs are also available under NCBI GenBank Accession Numbers PQ002243 - PQ002350 and MW447658 - MW447770 and raw sequencing data is available under NCBI Sequence Read Archive Accession numbers associated with BioSample accessions SAMN42123204 - 42123391 within BioProject PRJNA1129077.
