ClearInvestigation of Microplastics from Deep-Sea Antarctic and West Coast North American Sediments
Microplastics were identified in deep-sea sediments from both Antarctic and North American Pacific sites, confirming that plastic pollution has reached even the most remote ocean floor environments far from human activity.
Microplastics in the sediments of Terra Nova Bay (Ross Sea, Antarctica)
The first survey of plastic contamination in Antarctic seafloor sediments from Terra Nova Bay found microplastics in all 31 samples collected, with a diverse range of polymer types. This confirms that even remote polar deep-sea sediments are not free of human-derived plastic pollution.
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.
Microplastic pollution in deep-sea sediments
Researchers analyzed deep-sea sediment cores and found microplastics present at depth, providing early evidence that deep-sea sediments globally accumulate microplastic pollution far from coastlines and at the seafloor.
Determination of the presence of microplastics in intertidal sediments of deception island, antarctica
Researchers determined the presence and characteristics of microplastics in intertidal sediments of Deception Island, Antarctica, providing evidence that plastic contamination has reached one of Earth's most remote environments and documenting the role of marine sediments as sinks for persistent microplastic pollution.
Fate of microplastics in deep-sea sediments and its influencing factors: Evidence from the Eastern Indian Ocean
Surface sediments from 26 sites in the deep basin of the Eastern Indian Ocean were analyzed for microplastics, finding concentrations ranging widely and influenced by water depth, distance from land, and ocean current patterns. The study extends deep-sea microplastic monitoring to the Indian Ocean and identifies oceanographic transport as a key control on plastic distribution.
Microplastics in the Southern Ocean: Findings from the Continuous Plankton Recorder in the Ross Sea and the East Antarctic Regions
This study found microplastics widely distributed in surface waters of the Southern Ocean near Antarctica, collected via continuous plankton recorder samples. The detection of plastics in these remote polar waters confirms that microplastic contamination has reached essentially every corner of the global ocean.
Microplastics in the Antarctic marine system: An emerging area of research
This paper reviewed microplastics research in the Antarctic marine system, identifying it as an emerging research area and documenting the first evidence of microplastic contamination in this remote polar environment.
Plastic occurrence, sources, and impacts in Antarctic environment and biota
Researchers reviewed evidence of plastic pollution in Antarctica, finding microplastics — mostly fibers — in sea ice, ocean water, sediments, and both marine and land animals, raising concern that even the most remote ecosystems on Earth are contaminated and that biodiversity and ecosystem functions may be at risk.
Microplastic pollution in deep-sea sediments and organisms of the Western Pacific Ocean
Researchers collected deep-sea sediment and organism samples from multiple sites in the western Pacific Ocean and found microplastics at all locations sampled, with depth, distance from land, and current patterns influencing accumulation, confirming the western Pacific deep sea as a significant microplastic sink.
Deep Sea Microplastic Pollution Extends Out to Sediments in the Northeast Atlantic Ocean Margins
Researchers surveyed deep-sea sediments across four areas of the Northeast Atlantic and detected microplastics at 75% of stations sampled, finding no hotspots and no clear correlation with depth or distance from land, demonstrating the widespread extent of deep-sea microplastic contamination.
Floating macro- and microplastics around the Southern Ocean: Results from the Antarctic Circumnavigation Expedition
Researchers surveyed floating macro- and microplastic pollution around the Southern Ocean islands, providing baseline abundance estimates for high southern latitudes. The data reveal that plastic contamination extends even to remote polar regions, with seabirds in the area confirmed to have been ingesting plastics since at least the 1960s.
Low prevalence of microplastic contamination in the bottom sediments and deep-sea waters of the Bransfield strait, Antarctica
Researchers conducted a baseline assessment of microplastic contamination in the deep-sea waters and bottom sediments of the Bransfield Strait in Antarctica. They found a low but measurable prevalence of suspected microplastic particles, predominantly fibers, even in this remote deep-sea environment. The findings confirm that microplastic pollution has reached some of the most isolated marine habitats on Earth.
High Quantities of Microplastic in Arctic Deep-Sea Sediments from the HAUSGARTEN Observatory
Researchers found high quantities of microplastics in deep-sea sediments from the Arctic HAUSGARTEN observatory, demonstrating that even remote deep Arctic seafloor environments have accumulated significant microplastic pollution.
First long-term evidence of microplastic pollution in the deep subtropical Northeast Atlantic
Researchers found microplastic particles in all 110 sediment trap samples collected over a 12-year period from 2,000-meter depths in the Northeast Atlantic, establishing the deep ocean as a long-term sink for microplastics with fluxes increasing over time.
Microplastics in Southern Ocean sea ice: a pan-Antarctic perspective
The first pan-Antarctic survey of microplastics in Southern Ocean sea ice found an average of 44.8 particles per liter across 19 archived ice core samples, with 19 different polymer types detected even in one of Earth's most remote regions. This confirms that microplastic contamination has reached the polar oceans and is being concentrated and transported by sea ice, with implications for the marine food web as the ice melts.
Occurrence and Distribution of Microplastics in Soils and Intertidal Sediments at Fildes Bay, Maritime Antarctica
Researchers found microplastic contamination in soils and intertidal sediments at Fildes Bay in Maritime Antarctica, with higher concentrations near research stations, demonstrating that even remote polar environments are affected by microplastic pollution.
Microplastics and POPs on the Southwestern Atlantic deep-sea floor: a study of megafauna and sediments
This study provided the first report of microplastics and persistent organic pollutants (POPs) in the Southwestern Atlantic deep-sea floor, examining both sediments and benthic megafauna. Microplastics and POPs were detected in deep-sea organisms and sediments, demonstrating that even remote deep-ocean environments in the Southern Hemisphere are contaminated by surface-derived plastic pollution.
Occurrence and distribution patterns of small microplastics (11-500µm) in the southern weddell sea off antarctica
Researchers assessed small microplastics in the 11-500 micron size range in the Southern Ocean, a region considered remote and pristine, filling a gap left by prior studies that focused on larger particles. Microplastics were detected even in this remote marine environment, suggesting widespread dispersal beyond populated regions.
Microplastic Pollution in Antarctic Environments
This review examines microplastic pollution in Antarctic environments, summarizing evidence that even this remote continent has been contaminated by plastic particles, with implications for its unique fauna, influence on global climate systems, and value as a pristine scientific reference site.
