Continuous stage (lake level), ice surface ablation, surface PAR and underwater PAR are measured at 20 minute increments for Lake Fryxell, Lake Hoare, East Lake Bonney and West Lake Bonney in Taylor Valley as part of the McMurdo Dry Valleys LTER project. MCM sometimes refers to these measurements as "blue box" data because the instrumentation used to be housed in a blue box.

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.

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes were 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.
