The underwater light fields of two Icelandic lakes of volcanic origin and differing trophic status, Thingvallavatn (oligotrophic) and Myvatn (eutrophic), were investigated. Gilvin and turbidity depth profiles were also measured. Diurnal variation in photosynthetically active radiation (PAR) reached...
