Data underlying the publication: Observations of intermittent cross-shore bed load transport on a low-energy beach

Dataset underlying the analysis and figures for the manuscript "Observations of intermittent cross-shore bed load transport on a low-energy beach".<br>Field measurements from the SEDRIB campaign conducted October-01 to October-09 2023 around the passing of Storm Ciaran at the Prins Hendrik Zanddijk: a man-made beach on the leeside of the barrier island Texel, bordering the Marsdiep basin that is part of the Dutch Wadden Sea. the SEDRIB campaign aims to gain new insights into the driving processes behind cross-shore bed load transport at this low energy beach. The data set consists of (1) Reconstructed bed geometry sampled at 15 minute interval with a Sand Ripple Profile Scanner over a footprint with 1.5 m diameter, (2) 16 Hz continuous timeseries of velocity from an Acoustic Doppler Velocimeter, processed into 15 minute statistics on waves and currents, (3) 3 hours of 51 Hz near-bed velocity profile data from an Acoustic Velocity and Concentration Profiler, taken on top of a shoreward migrating bed ripple.

本数据集支撑了论文《低能量海滩间歇性跨岸推移质输运观测》的分析与图表制作。该数据集源自2023年10月1日至10月9日在特塞尔屏障岛（Texel）背风侧的人工海滩普林亨德里克赞迪克（Prins Hendrik Zanddijk）开展的SEDRIB野外作业（SEDRIB），作业期间正值风暴希亚兰（Storm Ciaran）过境，该海滩毗邻属于荷兰瓦登海（Dutch Wadden Sea）一部分的马斯迪普盆地（Marsdiep basin）。SEDRIB野外作业旨在深入揭示该低能量海滩跨岸推移质输运的驱动机制。本数据集包含三类数据：(1) 采用沙纹剖面扫描仪（Sand Ripple Profile Scanner）在直径1.5米的采样覆盖区（footprint）以15分钟间隔采集的重建床面地形数据；(2) 由声学多普勒流速仪（Acoustic Doppler Velocimeter）采集的16Hz连续流速时间序列，经处理得到波浪与水流的15分钟统计参数；(3) 在向岸迁移的沙纹床面上采集的、时长3小时的51Hz近底流速剖面数据，该数据来自声学流速与浓度剖面仪（Acoustic Velocity and Concentration Profiler）。
