Drawings and pictures of Sand Scraper design and user manual for the device

The sand scraper was designed to determine the vertical variability of grain sizes at the beach surface. Here, designs, drawings, a video and photos of the sand scraper are provided to enable the reproduction of the device. Additionally, the manual of the original sand scraper is provided to give insight into the use of the device in the field. Note that the designs, drawings and photos show the most important mechanisms of the device but for full reproduction more details are needed. Please contact Christa van IJzendoorn ([e-mail]) and Pieter van der Gaag ([e-mail]) when you want to make a reproduction of the Sand Scraper.本沙滩刮样器（sand scraper）专为测定海滩表层沉积物粒径的垂直变异性而设计。本数据集提供了该刮样器的设计方案、工程图纸、视频资料与实拍照片，以支持该装置的复刻制作。此外，还附带原版沙滩刮样器的使用手册，可帮助使用者了解该装置在野外环境中的操作方法。请注意：上述设计方案、工程图纸与实拍照片仅展示了该装置的核心工作机制，若要完整复刻该装置，还需补充更多细节参数。若您需要复刻该沙滩刮样器，请联系克里斯塔·范·伊岑多恩（Christa van IJzendoorn，邮箱：[e-mail]）与皮特·范·德·加格（Pieter van der Gaag，邮箱：[e-mail]）。
