Underwater Photosynthetically Active Radiation (PAR) from in-situ Lake Primary Production Experiments in the McMurdo Dry Valleys of Antarctica (1995-2024, ongoing)

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, PAR is measured at one depth during primary production experiments in Dry Valley Lakes. This data set quantifies instantaneous underwater PAR at 10-meter depths in Lakes Bonney and Hoare, and at 7-meter depth in Lake Fryxell (depths vary after 2008, check data file for actual depth). Ambient PAR was also measured at the air-ice interface from each of these lakes.

作为南极洲麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）项目的组成部分，本数据集在干谷湖泊的初级生产力实验中，于单一深度开展光合有效辐射（Photosynthetically Active Radiation, PAR）测量。本数据集量化了邦尼湖与霍尔湖10米深度处、弗莱克塞尔湖7米深度处的瞬时水下光合有效辐射（2008年后测量深度有所变动，实际深度请查阅数据文件）。此外，本数据集还同步测定了上述各湖泊冰-气界面处的环境光合有效辐射。
