Table 1.

Optical properties and the concentrations of Chl a, shinorine, and palythine of the three ice layers on 14 March 2007. UVR:PAR ratio is normalized to incident radiation ratio right above the ice surface. Ice layers are surface 0–12-cm, middle 12–25-cm, and bottom 25–37-cm depth from ice surface.
