Underwater spectral irradiance in Masfjorden 2011, western Norway

Wavelength resolved underwater solar irradiance was measured on four selected dates in 2011 to support a nearby (within 500 m) cabled acoustic observatory (Prihartato et al. 2015, Christiansen et al. 2021, Kaartvedt et al. 2021) to study the behavior of mesopelagic fishes in Masfjorden, western Norway.
