Short summary
We propose here that the resident microbial community can influence the structure of sea ice, particularly near the ocean interface, by lowering the local freezing point through production of, effectively, antifreeze compounds. The result is improved environmental conditions for growth and, possibly, changes to heat transport through the ice. A mathematical model together with laboratory measurements are used to illustrate and support the hypothesis.
