Data presented here were collected during the cruise MSM56 with MARIA S MERIAN from Longyearbyen, Svalbard to Reykjavik, Iceland (July 2nd, 2016 - July 25th, 2016). In total, 133 underwater light profiles were collected at 68 stations (with at least three repititions), using a free-falling hyperspectral light profiler. The system used was a SEABIRD HyperPro II (SN 143, former Satlantic), equipped with a irradiance sensor to measure downwelling irradiance (Ed, SN 392) and a radiance sensor for upwelling radiance (Lu, SN 323). A reference unit was attached to the ship to measure the above water irradiance (Es, SN 393). The sensors were pre-calibrated by the manufacturer. Data were recorded with the SatView software (V 2.9.5_7) and processed from raw to Level1, 1b, 2, 2s to Level 3a using the ProSoft Processing software (V 7.7.19_2). Measured data were binned in 0.5 m depth intervals. A dark correction was made automatically based on shutter measurements by the instrument. Measurements with a tilt higher than ...
