2019 - 2019 Centre for Environment, Fisheries & Aquaculture Science (Cefas) CLiP Belize Microplastics in sediment 2019

This dataset contains 2 csv file. Belize_Sediment_Microplastics.csv file reports data on microplastic abundance in sediment expressed in number of particles for 5g sediment. Sediment was collected at six locations in Belize between May and June 2019, but only four were analysed for microplastics due to time restrictions (only PSA reported for the two sites left). The file also reports information on blank used for calculations, grab GPS coordinates, deployment time and the particulate size analysis (PSA) of the sediment. Belize_Sediment_Microplastics_FTIR.csv contains the profile of a ATR-FT-IR spectrum analysis of a plastic particle (>5mm). A READ-ME text file contains the legend of the columns of the csv file. A .zip file contains the picture of the plastic particle analysed with ATR-FT-IR.本数据集共包含2个CSV格式文件。其中Belize_Sediment_Microplastics.csv记录了伯利兹沉积物中的微塑料丰度数据，计量单位为每5克沉积物中的微塑料颗粒数。沉积物样本于2019年5月至6月间在伯利兹的6个采样点位采集，但受时间限制仅对其中4个点位开展了微塑料分析，剩余2个点位仅报告了颗粒物尺寸分析（Particulate Size Analysis, PSA）结果。该文件同时涵盖了计算所需的空白对照样品信息、采样点位的GPS坐标、采样部署时间，以及沉积物的颗粒物尺寸分析（PSA）数据。Belize_Sediment_Microplastics_FTIR.csv包含了粒径大于5mm的塑料颗粒的衰减全反射傅里叶变换红外光谱（ATR-FT-IR）分析谱图数据。另有一份READ-ME文本文件，内含上述CSV文件各列的表头释义。此外还有一个.zip压缩包文件，存储了经ATR-FT-IR分析的塑料颗粒的实拍图像。
