2023年3月8日 · More than 171 trillion pieces of plastic are now estimated to be floating in the world's oceans, according to scientists. Plastic kills fish and sea animals and takes hundreds of years to...

A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch. [10] [11] This growing patch contributes to other environmental damage to marine ecosystems and species.

The Great Pacific Garbage Patch (GPGP) is the largest of the five offshore plastic accumulation zones in the world’s oceans. It is located halfway between Hawaii and California. PLASTIC ACCUMULATION. It is estimated that 1.15 to 2.41 million tonnes of plastic are entering the ocean each year from rivers.

2023年4月17日 · In a new study published in the Nature Ecology & Evolution journal on Monday, a team of researchers revealed that dozens of species of coastal invertebrate organisms have been able to survive and...

2023年8月7日 · Here we present a 3D global marine mass budget of buoyant plastics that resolves this discrepancy. We assimilate observational data from different marine reservoirs, including coastlines, the...

2014年12月10日 · Here we report an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891).

Floating plastic is easier to spot and collect using nets and amounts are still debated. A 2014 study estimates that there are 5.25 trillion particles (or 244,000 metric tons) of plastic floating in the ocean. A 2017 study found that 79,000 metric tons of plastic are floating in …

The name conjures images of a floating landfill in the middle of the ocean, with miles of bobbing plastic bottles and rogue yogurt cups. While it's true that these areas have a higher concentration of plastic than other parts of the ocean, much of the debris found in these areas are small bits of plastic, or microplastics, smaller than 5mm in ...

2023年3月8日 · To address this need, we used previously published and new data on floating ocean plastics (n = 11,777 stations) to create a global time-series that estimates the average counts and mass of small plastics in the ocean surface layer from 1979 to 2019.

2021年12月1日 · In this article, we take stock of the most recent measurements of their size distribution on the ocean surface. We confront the observed size distribution to the commonly invoked degradation modes of plastics and propose a scenario that accounts for the quite unusual features of the size distribution of floating debris.
