Origin and seasonal dynamics of pelagic microplastic deposition in Fram Strait, Arctic
AI summary Read the abstract
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.
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

Origin and seasonal dynamics of pelagic microplastic deposition in Fram Strait, Arctic
AI summary Read the abstract
Researchers analyzed microplastics isolated from sediment trap samples collected at the HAUSGARTEN observatory in Fram Strait, Arctic, between September 2019 and July 2021, measuring particle fluxes and seasonal dynamics using µ-FTIR imaging. They found microplastic fluxes of 0-2.9 particles per square meter per day with spring maxima, providing insight into vertical transport and deposition dynamics in the Arctic Ocean.
Origin and intra-annual variability of vertical microplastic fluxes in Fram Strait, Arctic Ocean
AI summary Read the abstract
Sediment trap data from Fram Strait in the Arctic Ocean revealed temporal and spatial variability in vertical microplastic fluxes, with MP concentrations and composition varying seasonally. The study provided evidence that the Arctic deep sea receives a continuous supply of MPs via vertical settling, driven by ocean circulation and ice dynamics.
Anthropogenic footprints: litter and microplastic pollution in the Fram Strait
AI summary Read the abstract
Litter and microplastic pollution were surveyed in the Fram Strait — an area experiencing increasing Arctic shipping traffic as sea ice retreats — documenting accumulation patterns and composition of anthropogenic debris. The study links rising human presence in this strategic Arctic gateway to growing litter pollution, with microplastics found throughout the water column.
Quantification and Identification of Microplastics in Arctic Sea Ice
AI summary Read the abstract
This thesis quantified and identified microplastics in Arctic sea ice from the Fram Strait using focal plane array-based micro-FTIR spectroscopy, developing appropriate ice core preparation procedures as a first step in building knowledge about microplastic pollution in polar ice. The work fills a knowledge gap about plastic contamination in remote polar regions, where sea ice may trap and concentrate microplastics transported from distant sources.
Microplastics in the Eurasian Arctic surface water: main sources and drivers of spatiotemporal variability
AI summary Read the abstract
Researchers conducted the most extensive survey to date of floating microplastics in the Eurasian Arctic Ocean, collecting 220 surface and 180 subsurface water samples across six research cruises from 2019 to 2022 in the Barents, Kara, Laptev, and East-Siberian Seas using Neuston nets. The study characterised the main sources and spatiotemporal drivers of microplastic distribution in this sensitive polar region, with findings relevant to understanding the Arctic as a sink for global plastic pollution.
