Fig. 1: Circumpolar krill faecal pellet carbon sequestration flux.
From: Antarctic krill sequester similar amounts of carbon to key coastal blue carbon habitats
The spatially varying parameters (a) krill density (ind m−2, January mean for data spanning 1926–2016) and (b) carbon sequestration depth, used along with egestion and attenuation rate to give (c) nominal krill faecal pellet carbon sequestration flux (FPCflux), attenuated to the carbon sequestration depth. The resolution is 2° latitude by 6° longitude. Note: the carbon sequestration depths are assumed constant in time (b), but data in (a, c) are for the month of January. See Supplementary Fig. S1 for the circumpolar densities per month for the entire time series. The solid black line represents the location of the Antarctic Polar Front.
