DOI: 10.1007/s00300-020-02751-x
Abstract: Sea ice algae, comprised mainly of diatoms, are the main primary producers in polar ecosystems, and they are generally distributed with the highest biomass at the bottom of ice. The taxonomy of ice algae has… read more here.

DOI: 10.1016/j.orggeochem.2018.06.002
Abstract: Abstract Degradation of palmitoleic acid (C 16:1ω7 ), the main fatty acid component of sea ice-associated (sympagic) diatoms, was monitored in Arctic sea ice at the beginning of ice melting and in the underlying sinking… read more here.

DOI: 10.1111/gcb.14392
Abstract: How the abundant pelagic life of the Southern Ocean survives winter darkness, when the sea is covered by pack ice and phytoplankton production is nearly zero, is poorly understood. Ice-associated ("sympagic") microalgae could serve as… read more here.

Female Pacific walruses (Odobenus rosmarus divergens) show greater partitioning of sea ice organic carbon than males: Evidence from ice algae trophic markers

DOI: 10.1371/journal.pone.0255686
Abstract: The expected reduction of ice algae with declining sea ice may prove to be detrimental to the Pacific Arctic ecosystem. Benthic organisms that rely on sea ice organic carbon (iPOC) sustain benthic predators such as… read more here.
