[MITgcm-support] Blocking of light by sea ice and plankton

I am about to start biogeochemical modelling using the BLING package, and have a couple of questions regarding the treatment of light availability:
1. Does BLING by default set light penetration to zero underneath sea ice, or does it allow for limited penetration subject to a strong attenuation coefficient? If the latter, does BLING take the value of effective sea ice thickness HEFF directly from the Sea Ice package, or does it do something more sophisticated (like a sub-grid scale parametrization of the thickness distribution)?
2. Does BLING take the self-shading effect of phytoplankton themselves into account for light calculations?
I appreciate that these are potentially broad questions but any guidance would be much appreciated.
Many thanks in advance,
University of Edinburgh
