Photosynthetic active radiation (PAR) - absolute values

Photosynthetic active radiation (PAR) immediately under the ice. The hole in the ice was covered with an opaque plate during the measures. For the data in the "PAR_intensity_under_ice" column, the value represents the amount of light available under the ice at 0m as umol_per_m2_per_s .
