Publikováno v: Geosciences, Vol 7, Iss 3, p 52 (2017)

A numerical mechanism connecting ice algal ecodynamics with the buildup of organic macromolecules is tested within modeled pan-Arctic brine channels. The simulations take place offline in a reduced representation of sea ice geochemistry. Physical dri
