Effects of kelp canopy on underwater light climate and viability of brown algal spores in Kongsfjorden (Spitsbergen)

We measured the effects of underwater light in summer 2015 on kelp spore parameters (Fv/Fm, pigment concentration, motility, phlorotannin content and germination success). Alaria esculenta spores were exposed in the laboratory to light conditions as found under no to very dense kelp canopies for 8 t...
