High-resolution measurements of physicochemical variables by two autonomous lander systems in the shallow water column (~ 1 m water depth) of a peatland rewetted with brackish water from the Baltic Sea

This directory contains the data from water velocity measurements that took place on the German Baltic Sea coast in the summer of 2021 and are associated with multi-parameter investigations on spatial and temporal dynamics of the greenhouse gas distribution in a rewetted peatland. The temporally high-resolution measurements were carried out with two autonomous lander systems. The water velocities were measured at "lander 2" at a water depth of approx. 1 m with an upward-looking acoustic current profiler (Aquadopp instrument). The sensor was deployed in an approx. 20 m wide channel that connects the rewetted peatland with the adjacent Kubitzer Bodden (Baltic Sea). Regular water level changes resulted in high flow velocities in both directions through the channel. The high-resolution data on physicochemical measurements can be found under: https://doi.pangaea.de/10.1594/PANGAEA.964839.

本数据集包含2021年夏季在德国波罗的海沿岸获取的水流速度实测数据，该数据关联一项针对复湿泥炭地（rewetted peatland）内温室气体分布时空动态的多参数调查研究。本次高时间分辨率的实测工作采用两套自主式着陆器系统完成。水流速度的实测工作在“着陆器2号”处开展，测点水深约1米，采用向上指向式声学流速剖面仪（Aquadopp仪器）完成。该传感器部署于一条宽约20米的水道内，该水道连接复湿泥炭地与邻近的库比策湾（Kubitzer Bodden，波罗的海海域）。周期性的水位变化使得该水道内出现双向高流速水流。理化参数实测的高分辨率数据可通过以下链接获取：https://doi.pangaea.de/10.1594/PANGAEA.964839。
