Transfer of ice algae carbon to ice-associated amphipods in the high-Arctic pack ice environment

Sympagic (ice-associated) amphipods channel carbon into the marine ecosystem. With Arctic sea ice extent in decline, it is becoming increasingly important to quantify this transfer of sympagic energy. Recently, a method for quantifying sympagic particulate organic carbon (iPOC) in filtered water samples was proposed based on the abundances of the Arctic sea ice biomarker IP25. Here, we tested the hypothesis that adoption of this method could...
