NIOZ racetrack sand-shell experiment, data belonging to the paper: Sediment shell-content diminishes current-driven sand ripple development and migration

Data collected from racetrack flume experiments conducted at NIOZ - Yerseke, the Netherlands. The experiment investigated the effect of shells within medium sand on ripple dynamics. Time-lapse photos, GoPro video footage and ADV measurements were taken from the two separate experiments: Constant flow experiment (6 treatments) and Acceleration (ACC; 11 treatments) flow experiment.本数据集采集自荷兰皇家海洋研究所（NIOZ）耶尔塞克基地开展的跑道式水槽实验。本次实验探究了中砂基质内的贝壳对沙波动力学过程的影响。数据来源于两组独立实验：恒定流实验（含6个处理组）与加速流（ACC；含11个处理组）实验，采集的观测内容包括延时摄影照片、GoPro视频素材以及声学多普勒测速仪（Acoustic Doppler Velocimeter，ADV）的测量数据。
