  1. Abundances are shown for each of the five drifting trap deployments (DF 1–5), as well as a mean across all traps with standard deviation (SD). Salp (Salpa thompsoni) abundances are based on quantitative oblique net tows and integrated over 170 m. Krill (Euphausia superba) abundances are based on the hydroacoustic survey integrated over the top 200 m. Day and night were defined according to the local time of sunrise and sunset as the periods from 06:00 am to 19:00 pm, and from 19:00 p.m. to 06:00 a.m., respectively (UTC –03:00).
