As part of the McMurdo Dry Valleys Long Term Ecological Research program, continuous stage (lake level), ice surface ablation, surface PAR, and underwater PAR are collected at various lakes throughout the McMurdo Dry Valleys of Antarctica. This package contains data measured at 20 minute intervals for Lake Fryxell, Lake Hoare, East Lake Bonney, and West Lake Bonney in Taylor Valley as well as Lake Miers in Miers Valley. 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 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.

As part of the McMurdo Dry Valleys Long Term Ecological Research program, continuous stage (lake level), ice surface ablation, surface PAR, and underwater PAR are collected at various lakes throughout the McMurdo Dry Valleys of Antarctica. This package contains daily measurement summaries derived from high frequency data for Lake Fryxell, Lake Hoare, East Lake Bonney, and West Lake Bonney in Taylor Valley as well as Lake Miers in Miers Valley. MCM sometimes refers to these measurements as "blue box" data because the instrumentation used to be housed in a blue box.
