k_bs 15.0 m^-1 blue-green light attenuation per metre in snow.

k_bi 2.0 m^-1 blue-green light attenuation per metre in ice.
k_rs 35.0 m^-1 red light attenuation per metre in snow.
k_ri 4.0 m^-1 red light attenuation per metre in ice.
R_bi 0.5 fraction of photosynthetically available light in the blue-green region

albedo_snow 0.6 Grenfell & Perovich 1984 0.6 to 0.81

ka_star 0.03 Soohoo 1987 (neglects wavelength dependence)
p_IBice 0.9 Prop. of ice. bacteria taken when detrit eaten in wc 0.6 - 1

For each primary producer group (including the ice active groups ) add the following value:

#Photoinhibition

PBmax_D_PS 0.44

#Photosynthetic efficiency

Beta_D_PS 0.002

Then for each predator we need a value that indicates how far the predator can eat into the ice - similar to how they can forage into the sediment:

The following values are the same values that are used for foraging into the sediment and therefore have not real world value at all. Do not use these values in your model!

Depth consumers can dig into, are found down to in the ice
