Photosynthetic active radiation (PAR) - relative values

Relative 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__percent_under_ice" column, the value represents the percentage of PAR under the ice at 0m, calculated so that 100% represents the amount of light above the ice.
