Data underlying the publication: Detection of suspended macroplastics using Acoustic Doppler Current Profiler (ADCP) echo

Dataset of ADCP data used to test to which extend items are detectable using ADCP echo. The objectives of the exploratory research were to: (1) determine the range of echo intensity and the effect item characteristics, such as orientation, form and material, have on this echo intensity, (2) confirm the detectability of the plastic items in a natural environment with other disturbances such as air bubbles and aquatic life, and (3) evaluate an ADCP plastic monitoring method in the field with simultaneous net measurements. We deployed three ADCPs in three different environments. In a basin and harbor, (semi-)controlled experiments are undertaken where an ADCP is fixed horizontally below the water surface and plastics are introduced within the beam. In a river an uncontrolled experiment is undertaken, where a vessel mounted ADCP is deployed and 'naturally' present plastics are studied. The dataset contains raw ADCP data files.

本数据集为声学多普勒流速剖面仪（Acoustic Doppler Current Profilers，ADCP）回波相关数据集，用于测试利用ADCP回波可探测目标物的程度。本探索性研究的目标包括：(1) 明确回波强度的取值范围，以及目标物的取向、形态、材质等特征对该回波强度的影响；(2) 验证在存在气泡、水生生物等干扰因素的自然环境中，塑料类目标物的可探测性；(3) 结合同步网捕测量，在实地场景下评估ADCP塑料监测方法的应用效果。研究团队在三类不同环境中部署了三台ADCP：在水池与港口场景中开展半受控实验，将ADCP水平固定于水面下方，并将塑料样本置于其波束探测范围内；在河流场景中开展非受控实验，部署船载ADCP，对自然存在的塑料垃圾进行观测研究。本数据集包含原始ADCP数据文件。
