Temperature (°C), salinity (psu) and daily doses (moles of photons per metre squared per day) of UVB (280 to 320 nm), UVA (320 to 400 nm) and PAR (400 to 700 nm) as well as their ratios; including the data of all sampling days at Hiddensee (autumn campaign, September to October) and Helgoland (spring campaign, April to May). Numbers in italics indicate the use of data from the nearby coastal station Zingst (30 km).
