Underwater photosynthetically active radiation (PAR) vertical profiles collected from lakes in the McMurdo Dry Valleys, Antarctica (1993-2022, ongoing)

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes are monitored for photosynthetic active radiation (PAR) levels. This data set exemplifies the vertical profile of underwater PAR profiles in perennial ice covered lakes and ambient PAR measured at the air-ice interface. Profile data can be used to calculate extinction coefficients for the water column and ice layer.

作为南极麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）项目的一部分，研究人员对湖泊的光合有效辐射（photosynthetic active radiation, PAR）水平进行监测。本数据集展示了常年冰盖湖水下PAR剖面的垂直分布特征，以及在气冰界面测量的环境PAR数据。剖面数据可用于计算水柱与冰层的消光系数。
