Abstract

Sandy coastal beaches are an important nesting habitat for marine turtles and a known sink for plastic pollution. Existing methodologies for monitoring the spatiotemporal patterns of abundance and composition of plastic are, however, disparate. We engaged a global network of marine turtle scientists to implement a large-scale sampling effort to assess microplastic abundance in beach sediments on marine turtle nesting beaches. Sand samples were collected from 209 sites spanning six oceans, microplastics (1-5 mm) were extracted through stacked sieves, visually identified, and a sub-sample verified via Fourier-transform infrared spectroscopy. Microplastics were detected in 45 % (n = 94) of beaches and within five ocean basins. Microplastic presence and abundance was found to vary markedly within and among ocean basins, with the highest proportion of contaminated beaches found in the Mediterranean (80 %). We present all data in an accessible, open access format to facilitate the extension of monitoring efforts and empower novel analytical approaches.

海龟筑巢海滩微塑料丰度和特征的全球评估。

沙滩是海龟重要的筑巢栖息地，也是众所周知的塑料污染的集散地。然而，用于监测塑料丰度和组成的时空模式的现有方法是不同的。我们与全球海龟科学家网络合作，进行了大规模采样工作，以评估海龟筑巢海滩海滩沉积物中的微塑料丰度。从6个海洋的209个地点收集沙样，通过堆叠筛提取微塑料（1-5 mm），进行视觉识别，并通过傅里叶变换红外光谱对子样进行验证。在45% （n = 94）的海滩和五个海洋盆地内检测到微塑料。发现微塑料的存在和丰度在海洋盆地内部和海洋盆地之间差异显著，地中海海滩受污染的比例最高（80%）。我们以可访问的开放获取格式呈现所有数据，以促进监测工作的扩展并授权新的分析方法。

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
