Microplastics primarily provide habitats for benthic microalgae in Fujian coastal waters of China. Wang et al.

This is raw data on epimicroplastic microalgae and phytoplankton communities. Samples were collected from three semi-enclosed bays—Dongshan Bay, Luoyuan Bay, and Quanzhou Bay—located in Fujian Province. Specifically, samples from Luoyuan Bay, Dongshan Bay, and Quanzhou Bay were collected in March 2021, April 2022, and May 2022, respectively. This dataset is composed of sampling dates, sampling locations, taxonomic information on phyla, genera, and species, and the cell density of microalgae.
