塑料污染在整个海洋环境中无处不在，但对全球漂浮塑料的丰度和重量的估计缺乏数据，特别是来自南半球和偏远地区的数据。在这里，我们报告了从24次考察（2007-2013年）中对全球海洋中漂浮的塑料颗粒总数及其重量的估计，这些考察跨越了所有五个亚热带环流、澳大利亚沿海、孟加拉湾和地中海，进行了表面净拖网（N = 680）和大型塑料碎片的目视调查样带（N = 891）。根据我们的数据校准的漂浮碎片分散的海洋学模型，并校正风力驱动的垂直混合，我们估计至少有5.25万亿个颗粒，重达268,940吨。当比较四种尺寸类别时，两种<4.75 mm的微塑料和中宏观塑料>4.75 mm，与预期的破碎率相比，从海面观察到大量的微塑料损失，这表明有机制从海洋表面去除<4.75 mm的塑料颗粒。
Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. 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). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.
