  1. Salp abundances are based on quantitative oblique net tows and integrated over 170 m. Krill abundances are based on the hydroacoustics survey integrated over the top 200 m. For FP, the volume and carbon−specific production rates and sinking velocities are given for krill and salps, respectively. FP carbon content is shown for krill FP and the two types of salp FP (type 1 = phytoplankton, type 2 = ingested krill FP). Values are given as mean across all sediment trap deployments. The SD is shown for each value.
