This repository contains both R code and a dataset associated with the article "Microbial plankton occurrence database in the North American Arctic region: synthesis of recent diversity of potentially toxic and harmful algae". The R code and data are provided for data processing, analysis, and visualization. ... : The Arctic Ocean is currently undergoing significant transformations due to climate change, leading to profound changes in its microbial planktonic communities, including photoautotrophic prokaryotes and eukaryotes, as well as heterotrophic, phagotrophic, and mixotrophic protistan species. Among these unicellular organisms, potentially toxic and/or harmful algal species (hereafter referred to as "HA") are of particular concern, as they pose a threat to human and ecosystem health if they potentially spread into Arctic waters. Despite their importance, the spatial and temporal distribution of these communities in the North American Arctic is poorly understood. To address this gap, we compiled and synthesized a large dataset from various sources, partitioned into nine regions based on the Large Marine Ecosystem classification. Our dataset contains 385 348 georeferenced data points and 18 268 unique sampling events, encompassing 1442 unique taxa, with Heterokontophyta (notably diatoms) and Dinoflagellata being ...
