Cumulative solar irradiance and potential large-scale sea ice algae distribution off East Antarctica (30 o E-150 o E)
We present a computational model of the largescalecumulative light exposure of sea ice in the SouthernOcean off East Antarctica (30E-150E). The model usesremotely sensed or modelled sea ice concentration, snowdepth over sea ice, and solar irradiance data, and tracks seaice motion over the season of...
