  1. Cycle duration, integrated net primary production (NPP) and chl a integrated for the euphotic zone (0.1% surface PAR), S. thompsoni abundance (m−2) and biomass (g C m−2) by stage (means ± SE). Salp SA-Sc had two deployments of Particle Interceptor Traps (PIT), so the cycle is divided into A and B time periods. Experiments are listed in the order they were sampled. Note that the most abundant salp was S. thompsoni, and the abundances of the “other salp species” are aggregated, since they were low, to indicate their contribution to both “salp” and “non-salp” locations.
