Researchers reported some of the first measured values for microplastic particles in Arctic polar waters, finding contamination even in these remote high-latitude waters and raising questions about long-range transport mechanisms.
Microplastics in Surface Waters of the Russian Arctic Seas: Distribution, Concentration, Identification, and Eco-Risks for Fish
Microplastics were detected across surface waters of the Russian Arctic seas, with concentrations and polymer types varying by region and season. The findings document that even high-latitude Arctic waters are not spared from microplastic contamination, likely transported by ocean currents and rivers.
Abundance and distribution of microplastics in the surface sediments from the northern Bering and Chukchi Seas
This study documented the first records of microplastic contamination in surface sediments from the northern Bering and Chukchi Seas, including waters near Arctic Alaska, finding widespread but variable particle abundances. The findings confirm that even high-latitude Arctic seafloor sediments receive microplastic input, likely transported by ocean currents from distant sources.
Microplastic contamination in the western Arctic water column: A transition from pristine to polluted
Researchers collected 324 water column samples from the western Arctic Ocean using a CTD rosette (9-297 m depth) and detected microplastics in all areas at an average of 0.06 particles/L. Blue fibrous polyolefin microplastics dominated, with highest concentrations in the Beaufort Sea, indicating that the western Arctic is transitioning from a relatively pristine to a measurably polluted state.
Microplastics Distribution within Western Arctic Seawater and Sea Ice
Researchers investigated microplastic distribution in seawater and sea ice of the western Canadian Arctic, including the previously unstudied Canadian Arctic Archipelago and Tallurutiup Imanga National Marine Conservation Area.

Spatio-temporal variation of microplastic pollution in the sediment from the Chukchi Sea over five years
Researchers assessed microplastic contamination in sediments from the Chukchi Sea across three Arctic voyages in 2016, 2018, and 2020, finding abundances ranging from 33 to 105 items per sample with spatial and temporal variability. The study also explored correlations between Arctic sea ice variation and microplastic accumulation in sediments.
Spatiotemporal trends in microplastic pollution of surface waters of the Eurasian Arctic
Researchers conducted the most extensive survey to date of floating microplastics in the Eurasian Arctic Ocean, collecting 200 surface water samples across four Arctic seas over four years using standardized methods. The study provides a crucial baseline for tracking whether microplastic contamination in this remote and climate-sensitive ocean region is increasing over time, which matters because Arctic ecosystems are already under severe stress and microplastics can further harm the marine food web from plankton to Arctic wildlife.
Distribution characteristics of microplastics in surface and subsurface Antarctic seawater
Researchers characterized microplastic distribution in both surface and subsurface Antarctic seawater, finding plastic contamination present at multiple depths and dominated by fibers and fragments, highlighting that even remote polar waters are affected by plastic pollution.
Investigation of microplastic pollution in Arctic fjord water: a case study of Rijpfjorden, Northern Svalbard
Researchers investigated microplastic contamination in the remote Rijpfjorden fjord in Northern Svalbard, sampling both surface water and the water column down to 200 m, and found widespread microplastic presence even in this Arctic environment far from major pollution sources.
Microplastics in the Eurasian Arctic surface water: main sources and drivers of spatiotemporal variability
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.
A first assessment of microplastics and other anthropogenic particles in Hudson Bay and the surrounding eastern Canadian Arctic waters of Nunavut
Scientists collected surface water, zooplankton, sediment, and snow samples from Hudson Bay to northern Baffin Island and found microplastics in all sample types, providing the first comprehensive assessment of microplastic contamination across this broad eastern Canadian Arctic region.
Microplastics in the Arctic: a transect through the Barents Sea
Researchers collected large-volume sub-surface water samples along transects through the Barents Sea to quantify and characterize microplastics, examining the role of regional ocean currents in concentrating plastic debris. The study contributes baseline data on microplastic distribution in this productive Arctic marginal sea mooted as a potential sixth ocean gyre for plastic accumulation.
The occurrence and sources of microplastics to Arctic and sub-Arctic beaches: human influence on local microplastic hotspots
Researchers characterized microplastic occurrence and sources at Arctic and sub-Arctic beaches, finding that proximity to human settlements creates local hotspots, while more remote beaches receive microplastics primarily through long-range oceanic transport.
Microplastics in sea ice and seawater beneath ice floes from the Arctic Ocean
Microplastic concentrations in Arctic sea ice were orders of magnitude higher than in the underlying seawater, with 2 to 17 particles per liter in ice versus 0 to 18 particles per cubic meter beneath floes in the Central Basin. Backward trajectory modeling suggested the sea ice originated from the Siberian shelf and other Arctic regions, consistent with long-range transport of microplastics to the pole.
Systematical insights into distribution and characteristics of microplastics in near-surface waters from the East Asian Seas to the Arctic Central Basin

First Evidence of Microplastic Occurrence in the Marine and Freshwater Environments in a Remote Polar Region of the Kola Peninsula and a Correlation with Human Presence
Researchers documented the first evidence of microplastic contamination in both marine and freshwater environments in a remote tundra region of the Kola Peninsula near the Arctic. Microplastics were found in all water samples from the Barents Sea and nearby lakes, with concentrations correlating to the proximity of a human research station. The findings indicate that even minimal human presence in remote polar regions can contribute to local microplastic pollution.

Microplastics in the Eurasian Arctic surface water: main sources and drivers of spatiotemporal variability
Researchers conducted the most extensive survey of floating microplastics in the Eurasian Arctic to date, collecting 220 surface water and 180 subsurface water samples across the Barents, Kara, Laptev, and East-Siberian seas during six cruises from 2019 to 2022. They found a strong west-to-east gradient in microplastic pollution, declining from 19.0 micrograms per cubic meter in the Barents Sea to 2.0 micrograms per cubic meter in the East-Siberian Sea, with the Kara Gate Strait showing the highest concentration at 640 micrograms per cubic meter, suggesting the Barents Sea as the primary source of microplastics in the Siberian Arctic.
