North Sea drifter trajectories 2024

Trajectories of twelve oceanic drifters deployed in the Wadden Sea just north of the town of Moddergat on 25 April 2024. The drifters are so-called Stokes drifters, built by MetOcean in Canada. They are small, white, floating devices that are designed to follow the water motion in the Wadden Sea. The drifters are equipped with a GPS and a satellite transmitter, so that we can track their position in real time. The data have not been cleaned for outliers. Note that transmission frequencies change during the trajectories (as indicated in the time variable) An interactive visualisation of the drifters can be seen here.本数据集包含2024年4月25日在莫德加特（Moddergat）镇北侧瓦登海（Wadden Sea）部署的12台海洋漂流浮标的运动轨迹。此类浮标为加拿大MetOcean公司研发的斯托克斯漂流浮标（Stokes drifters）：该设备为小型白色漂浮装置，专为追踪瓦登海的水体运动而设计，搭载GPS与卫星发射机，可实现位置的实时追踪。本数据集未针对异常值进行清洗处理。请注意，漂流过程中卫星信号的发射频率会发生变化（具体可参见时间变量的标注）。浮标运动轨迹的交互式可视化内容可通过此处查看。
