Hydrological data for 20 locations every 500 m along Caerlaverock saltmarsh (UK) between March 2021 and 2022

Raw acceleration data for 20 locations deployed every ~500 m on the mudflat ~2 m in front of eroding or expanding edges of Caerlaverock saltmarsh, Solway Firth, Scotland. Acceleration data was gathered by the Mini Buoy (B4+ design) at rates of either 1 second (monthly redeployments) or 10 seconds (quarterly redeployments) between March 2021-2022. The data has been cleaned to remove any data gathered before/after deployment. Coordinates of each location and the status of the marsh edge (eroding or expanding), and images of the marsh edge at each Mini Buoy deployment are also present. The data is being used to identify hydrological thresholds (inundation duration, current and wave orbital velocities) that determine whether saltmarshes expand or erode.

本数据集包含苏格兰索利韦湾Caerlaverock盐沼边缘约2米处，每隔约500米部署的20个位置的原始加速度数据。加速度数据由Mini Buoy（B4+设计）以每秒1次（每月重新部署）或每10秒1次（每季度重新部署）的频率，于2021年3月至2022年间采集。数据已进行清洗，移除了部署前后的任何采集数据。数据集中还包括每个位置的坐标、沼泽边缘的状态（侵蚀或扩张），以及每个Mini Buoy部署时沼泽边缘的图像。该数据被用于识别决定盐沼扩张或侵蚀的洪水阈值（淹没持续时间、水流和波浪轨道速度）。
