Year-round utilization of sea ice-associated carbon in Arctic ecosystems

This record contains a comprehensive synthesis of previously published highly branched isoprenoid (HBI) results, providing a quantitative spatial and temporal assessment of carbon partitioning within the Arctic marine ecosystem and validating estimates of sea-ice particulate organic carbon (iPOC) values as quantitative predictors of ice algal carbon in Arctic food webs.

Purpose
Sea ice primary production is considered a valuable energy source for the Arctic, yet the extent that it fuels this ecosystem is unclear. To resolve this, we quantify ice algal carbon signatures in over 2300 samples from 155 species including invertebrates, fish, seabirds and marine mammals collected between 1982 and 2019 across the Arctic shelves. Here we show sea-ice organic carbon signatures within 96% of the organisms investigated, which were collected year-round from January to December, suggesting continuous utilization of this resource. These results emphasize the important role of ice algal carbon through benthic retention that is available to consumers, supporting Arctic marine food webs year-round. Finally, we suggest that alterations to the phenology, distribution and biomass of ice-associated primary production anticipated with declining seasonal sea ice will disrupt sympagic-pelagic-benthic coupling and consequently the structure and the functioning of the food web which is critical for Indigenous Peoples, commercial fisheries, and global biodiversity.
