Mean animal biomass concentrations ranged between 0.106 to 0.811 g\/ m\u003Csup\u003E3\u003C\/sup\u003E during the day and 0.242 to 1.90 g\/m\u003Csup\u003E3\u003C\/sup\u003E at night for Cruise EN614. The mean animal biomass on Cruise EN640 ranged from 1.541 to 6.874 g\/ m\u003Csup\u003E3\u003C\/sup\u003E during the day and 2.505 to 6.291 g\/m\u003Csup\u003E3\u003C\/sup\u003E at night. Sampling stations were classified into habitat types identified by Weber et al. (2019) and Pham et al. (in prep): the young plume core (YPC), old plume core (OPC), outer plume margin (OPM), western plume margin (WPM), and oceanic seawater (OSW). In general, zooplankton \u0026delta;\u003Csup\u003E15\u003C\/sup\u003EN varied markedly and significantly among habitats for both cruises, with generally higher values in the YPC, OPC, WPM, and OSW habitats relative to the OPM habitat. Zooplankton \u0026delta;\u003Csup\u003E15\u003C\/sup\u003EN values reflect the sources of nitrogen supporting biological production, and trophic processing within the food web. Suspended particles collected from these habitats showed lower d\u003Csup\u003E15\u003C\/sup\u003EN values than the zooplankton, but we did not find a consistent increase in animal \u0026delta;\u003Csup\u003E15\u003C\/sup\u003EN with size. Vertical migration led to diel shifts in zooplankton d\u003Csup\u003E15\u003C\/sup\u003EN at the surface, with generally higher d\u003Csup\u003E15\u003C\/sup\u003EN values at night than during the day during both cruises.
