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: 10.1017/jog.2024.72
Abstract: Abstract Photosynthetically active radiation (PAR) at the ice-ocean interface is critical for primary production. The value of PAR is affected by the thickness of snow and sea ice, with additional absorbers (e.g. algae) further attenuating… read more here.

Dependency of Antarctic zooplankton species on ice algae‐produced carbon suggests a sea ice‐driven pelagic ecosystem during winter

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.

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.

Ice algae contributions to the benthos during a time of sea ice change: a review of supply, coupling, and fate

DOI: 10.3389/fenvs.2024.1432761
Abstract: The polymer-facilitated flux of ice algae on Arctic shelves can initiate benthic activity and growth after the nutritionally constrained winter period. Lipid-rich ice algae are readily consumed by benthos and those entering the sediment can… read more here.
