| Summary: | Measurements of transmitted irradiance under sea ice and corresponding incident solar radiation at the surface have been performed during the Polarstern expedition PS131, ATWAICE. During this expedition, three major ice floes were revisited to repeat measurements with a time gap of approximately one week and thereby analyze temporal development. Additionally, measurements on another ice floe were repeated 8 times within one day to observe the daily cycle of incoming and transmitted irradiance. All observations took place in the Fram Strait, north of Svalbard, between July 13 and August 6, 2022. The radiation measurements have been performed with Ramses spectral radiometers (TriOS, Rastede, Germany) in the wavelength range 316 to 952 nm. The incoming irradiance sensor was installed at approximately 1 m above the sea ice surface. The transmittance sensor was lowered through a hole (diameter about 10 cm) into the water down to 40 to 50 m depth. There are three datasets, two of them contain the raw data of the ... |
