Data for article: Microplastics in Arctic Waters of the Finnish Sámi Area

AI summary Read the abstract

This is the dataset for a study measuring microplastics in Arctic waters of the Finnish Sámi area in Lapland. The data include sampling coordinates, volumes, and particle counts from an Indigenous region that is increasingly affected by plastic pollution despite its remote location.

Description of the dataset: This dataset was created in 2021 and 2023. It was first made open in 2023 and later updated in 2024. Lapland_Sampling.xlsx contains all sampling dates and coordinates alongside with sample names, volumes, area descriptions and codes used to describe the samples in the article. Lapland_RawData.xlsx contains all the raw data for all the samples. This includes polymer types, particle sizes and an estimation of particle mass. Furthermore, the file contains a table with all the polymer types and their counts from all samples. Data creation and processing: The raw data was created by measuring filtered water samples with FPA-FTIR . The spectral analysis was done with siMPle (Primpke et al. 2020, Applied Spectroscopy, 74, 1127-1138, https://doi.org/10.1177/0003702820917760).
