Summary

Abstract: The intention of the Deep Krill Camera and Trap System was to monitor and capture krill found during deep CTD operations.

Two traps were installed on the CTD in place of Niskin Bottles. At pre-determined depths an internal light was illuminated and the traps were opened. After a set period of time a second trigger signal was sent to the traps, closing the entry point, encapsulating any Krill ...

Quality The Deep Krill camera system had no absolute feedback, so it could never be certainly known if the recording was occurring properly until the data were reviewed at the surface.

There appeared to be some interference between the CTD bottle firing and camera commands being transmitted to the CTD rosette. This was worked around by monitoring the feedback from the camera system, then transmitting the bottle firing trigger in between updates.
