Lake Murten is located in the Lake District in western Switzerland and so far, it has been poorly investigated. The Environmental Service of Fribourg (SEn) has monitored this lake once a month for several years by water profiles (water temperature, pH, dissolved oxygen, conductivity) at its deepest part. The SEn identified the stratification of water masses as one of the main causes for oxygen consumption in the hypolimnion. In the present study, a Lander System was deployed in Lake Murten from April to September 2015 at 20 m depth at the northwestern part of the lake to monitor water temperature and dissolved oxygen at higher resolution (30 s interval). These records were compared with time series of atmospheric parameters like atmospheric temperature, wind speed and precipitation. A clear correlation of lake temperatures with wind speed was observed during the Spring and Autumn. The water mass stratification evolved through the season and reached its peak during Summer, preventing surface turbulences to reach the deeper part (20 m) of the water column and to partially oxygenate the metalimnion.

高分辨率监测默滕湖（瑞士）的水温和氧气浓度

Murten湖位于瑞士西部的湖区，到目前为止，对其进行的调查很少。弗里堡环境服务局（SEn）每月对其最深处的水况（水温，pH，溶解氧，电导率）进行每月一次的监测。SEn将水团分层确定为次层水体中耗氧量的主要原因之一。在本研究中，自2015年4月至2015年9月，在湖西北部20 m深度的默滕湖部署了Lander系统，以更高的分辨率（间隔30 s）监视水温和溶解氧。这些记录与大气参数的时间序列（如大气温度，风速和降水）进行了比较。在春季和秋季期间，观察到了湖水温度与风速之间的明确关联。水质分层在整个季节演变，并在夏季达到最高峰，防止表面湍流到达水柱的较深部分（20 m）并部分氧化金属亚胺。
