Abundance, biomass, composition and grazing impact of the sea-ice meiofauna in the North Water, northern Baffin Bay
TL;DR: Meiofauna appear to be a minor contributor to the overall carbon flow in the sea-ice biota of the North Water during spring, and their potential as an important food source for higher trophic levels is ruled out.
Protist assemblages in winter sea ice: setting the stage for the spring ice algal bloom
TL;DR: The results indicate that differences in the timing of ice formation may have a greater impact on the abundance than structure of protist assemblages present in winter sea ice and at the onset of the spring ice algal bloom.

Enrichment of nutrients, exopolymeric substances and microorganisms in newly formed sea ice on the Mackenzie shelf
TL;DR: The data suggest that EPS enhance NH4 regeneration by acting as a carbon source for sea-ice heterotrophs or a substrate forSea-ice bacteria, and suggest that the presence of EPS may enhance the selective enrichment of large autotrophics.

TL;DR: In this paper, a two-box model was used to identify and assess physical, biological, and chemical processes responsible for the seasonal variability of DIC, DOC, total alkalinity (TA), partial pressure of CO2 (pCO2) and related parameters were measured over a full annual cycle.
Trophic structure and pathways of biogenic carbon flow in the eastern North Water Polynya

TL;DR: In the eastern North Water, most of the estimated annual new and net production of carbon (C) occurred during the main diatom bloom in 1998 as discussed by the authors, where at least 30% of total and new phytoplankton production occurred as dissolved organic carbon (DOC) and was unavailable for short-term assimilation into the herbivorous food web or sinking export.
