Future research:

UV: 1)The strongly multiple scattering environment around Scott Base and Tent Island is probably mainly the result of the highly reflecting snow and ice surface cover (high albedo). It would therefore be of some interest to measure the intensity distributions at other sites were the albedo may be different We have already proposed measurements at the South Pole, and again at Lake Vanda in a dry valley.
2)The transmission of the sea ice is very strongly affected by the snow cover, and it page break would be of considerable interest to measure the transmission and scattering properties of snow cover of varying thicknesses.
3)Measuring the colours of sea ice algae requires not a transmission measurement but a diffuse scattering measurement, using probably an integrating sphere. It will be of interest to see if any changes to the colour spectrum can be correlated with the enhanced radiation.
Sea-ice algae: 1)Recent studies have demonstrated that UVA radiation may also be injurious to plant growth, both in concert with UVB and in its own right Future research could examine the relationship of these two bands of radiation to growth rates of sea ice algae.
2)The algae at Tent Island was thicker than at Arrival Heights, and therefore there is the potential for algae closer to the surface to shade those lower down. The response to UV radiation of algae at different layers in the ice could also be studied.
