Fig. 1: Seasonal trend of carbon flux of krill.

a Seasonal particulate organic carbon (POC) flux (mg m−2 d−1; ±1 SD) and the flux of krill faecal pellets (FP), exuviae and carcasses (mg m−2 d−1; ±1 SD). Error bars are standard deviations from replicates (sub-samples) from each cup. b Relative contribution of krill FP, carcasses and exuviae to total POC. c Relative contribution of krill FP, carcasses and exuviae to total POC seasonal average (%, ±1 SD).
