Summary

Researchers analyzed microplastics isolated from sediment trap samples collected at the HAUSGARTEN observatory in Fram Strait, Arctic, from September 2019 to July 2021 using micro-Fourier Transform Infrared imaging to determine fluxes and seasonal dynamics. They found microplastic fluxes of 0 to 2.9 particles per square meter per day, with maxima occurring in spring 2020 and 2021, and investigated transport pathways driving the delivery of microplastics to this remote polar environment.

Study Type Environmental

Microplastic (MP) pollution has reached the remotest areas of the globe, including the polar regions. In the Arctic Ocean, MPs have been detected in snow, ice, sediment, water, and biota samples; yet their dynamics are still poorly understood. In order to elucidate the transport pathways and drivers of MPs in this fragile environment, this work aims to analyze MPs (≥ 11 µm) isolated from sediment trap samples, which were collected at the HAUSGARTEN observatory (Fram Strait) from September 2019 to July 2021. MP fluxes determined by µ-Fourier-Transform Infrared (FTIR) imaging were 0–2.9 MP m−2 d−1, with maxima in spring 2020 and 2021. All detected MPs were Also see: https://micro2024.sciencesconf.org/558864/document
