Surface irradiances/doses versus underwater irradiances/doses. Surface versus underwater irradiances/doses at the chlorophyll a maximum depth (Chl a max.) at Helgoland for the different wavelength ranges UVB (A), UVA (B) and PAR (C) including all data from profiles with pronounced chlorophyll a maxima. Values at both axes are in the energetic unit kilojoules per metre squared for UVB (A) and UVA (B) and in the quantametric unit micromoles of photons per meter squared per second for PAR (C); calculations see M&M.
