Pump-underway ship intake: microplastic concentrations on oceanic and coastal seawaters off the Canary Islands (Subtropical NE Atlantic)

we present a dataset obtained from a sampling methodology based on the connection of a microplastic sampling device of our own design to the pump-underway ship intake system of a research vessel (rv). the method has been proved cost effective, highly versatile and accurate, and able to sample particles down to 50μm from opportunity platforms, thus contributing to an emerging area of study, and particularly helpful to increase monitoring effort and reported data, and therefore serving as a valuable aid for the implementation of the marine strategy framework directive (msfd).sampling was performed in three consecutive oceanographic campaigns in subtropical ne atlantic over a year, repeating the same procedure, retrieving subsurface waters (- 4 m depth) while on navigation and while on coastal and oceanic stations. microplastic particles were found in the total stations and transects sampled. fibres (64.42%) were predominant over fragments (35.58%), being the concentration values over the data reported in other areas in the atlantic.

本报告呈现了一组数据集，该数据集通过将自创设计的微塑料采样设备与科研船舶（rv）的航行中泵入系统相连接而获得。此方法已被证实具有成本效益、高度灵活且精确，能够从机会平台采样下至50μm的颗粒，从而为新兴研究领域作出贡献，尤其是有助于提升监测力度和报告数据，因此可作为海洋战略框架指令（msfd）实施的有力辅助。采样工作在一年内的三个连续海洋学考察活动中于亚热带北大西洋进行，重复执行了相同程序，在航行及沿海和海洋站点采集了海底水（-4米深度）样本。在所采集的总站和横断面中发现了微塑料颗粒。纤维（占64.42%）在碎片（占35.58%）之上，其浓度值高于大西洋其他地区所报告的数据。
