Summary of measurements

-Imaging transects using In Situ Ichtyoplankton Imaging System (ISIIS); images collected.
-Imaging transects using the Underwater Video Profiler (UVP); images of plankton collected.
-Vertical CTD profiles between the surface and maximum depths of 550m.
-Oblique 780µm-mesh plankton net hauls.
-Glider deployed from 0-500m along an inshore-to-offshore transect.
-Drifting floats equipped with cameras were deployed to detect jellyfish.
