Abstract. This work presents a hyperspectral reflectance dataset of macroplastic samples acquired using Analytical Spectral Devices (ASD) FieldSpec 4. Samples analysed consisted of pristine, artificially weathered and biofouled plastic items and plastic debris samples collected in the docks of the Port of Antwerp and in the river Scheldt near Temse Bridge (Belgium). The hyperspectral signal of each sample was measured in controlled dry conditions in an optical calibration facility at the Flemish Institute for Technological Research, and, for a subset of plastics, under wet and submerged conditions in a silo tank at Flanders Hydraulics. The wet and submerged hyperspectral signals were measured in a mesocosm setting that mimicked environmentally relevant concentrations of freshwater microalgae and of suspended sediment. The ASD was equipped with an 8° field of view at the calibration facility, and a 1° field of view was used in the mesocosm setting. The dataset obtained complies with the Findability, Accessibility, Interoperability, and Reuse (FAIR) principles and is available in the open-access repository Marine Data Archive (https://doi.org/10.14284/530, Leone et al., 2021).

原始、风化和生物污染塑料的高光谱反射率数据集

摘要。这项工作提供了使用分析光谱设备 (ASD) FieldSpec 4 获取的大型塑料样品的高光谱反射数据集。分析的样品包括在安特卫普港码头和河流中收集的原始、人工风化和生物污染的塑料物品和塑料碎片样品Temse 桥（比利时）附近的斯海尔德特。每个样品的高光谱信号是在 Flemish Institute for Technology Research 的光学校准设施中的受控干燥条件下测量的，对于塑料的一个子集，在 Flanders Hydraulics 的筒仓罐中在潮湿和浸没条件下测量。在模拟淡水微藻和悬浮沉积物的环境相关浓度的中宇宙环境中测量湿和淹没的高光谱信号。ASD 在校准设施配备 8° 视野，在中宇宙设置中使用 1° 视野。获得的数据集符合可查找性、可访问性、互操作性和重用 (FAIR) 原则，可在开放访问存储库 Marine Data Archive 中获得 (https://doi.org/10.14284/530, Leone et al., 2021) .
