Data for: New insights into the coupling of tidal mudflats and coastal salt marshes

This dataset contains hydrodynamic data, depth-averaged suspended sediment concentrations (SSCs), sediment deposition data and data on the morphological evolution of the tidal mudflat for the coupled tidal mudflat-salt marsh system on the wave-exposed coast of the Dengie peninsula in the southeast of England (Tillingham, UK).
Data were collected during two field campaigns (25/05 - 28/06/2016 and 20/09 - 06/12/2016). Hydrodynamic data were collected using four pressure sensors (Solnist Levellogger, Model 3001) and corrected for variations in atmospheric pressure. Depth-averaged SSCs were measured using two turbidity profilers (Argus Suspension Meters (ASM) IV), one deployed on the tidal mudflat (130 m seaward of the edge of the salt marsh; ASM 2113) and the other at the marsh edge (ASM2115). Sediment deposition on the marsh surface was measured using filter traps (9 cm in diameter, attached to an equally sized petri dish) at four locations on the salt marsh platform (three filters were deployed at each location). The morphological evolution of the tidal mudflat was determined with tracer sticks, inserted into the mudflat and retrieved after five, occasionally 2 or 10, days. The tracer sticks consisted of coloured sand, mixed with a highly concentrated sugar solution and “baked” for three days at 50°C.

本数据集包含英国英格兰东南部登吉半岛（英国蒂林厄姆）波浪暴露海岸的潮滩-盐沼耦合系统的水动力数据、垂向平均悬浮泥沙浓度（Suspended Sediment Concentrations，SSCs）数据、泥沙沉积数据以及潮滩地貌演化数据。
数据采集于两次野外作业：2016年5月25日至2016年6月28日，以及2016年9月20日至2016年12月6日。
水动力数据采用4台压力传感器（Solnist Levellogger，型号3001）采集，并针对大气压力波动进行了校正。垂向平均悬浮泥沙浓度采用两台浊度剖面仪（Argus Suspension Meters (ASM) IV）测量，其中一台部署于潮滩上（距盐沼边缘向海侧130米处，编号ASM 2113），另一台部署于盐沼边缘（编号ASM2115）。
盐沼表面的泥沙沉积量通过滤膜捕集器（直径9cm，搭配同等规格的培养皿）进行测定，在盐沼平台共设置4个采样点位，每个点位部署3个滤膜。
潮滩的地貌演化通过示踪棒开展监测：将示踪棒插入潮滩，分别在5天（偶尔为2天或10天）后回收。示踪棒由彩色砂与高浓度糖溶液混合后，在50℃条件下烘烤三天制成。
