Vertical Profile of Photosynthetic Active Radiation in McMurdo Dry Valley 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
