[22-Aug-18] To investigate how carbon is exported to the deep ocean, traps are deployed to attempt to catch this falling marine snow so that it can be analyzed. During the EXPORTS cruise, sediment traps were deployed to the Twilight Zone to gather information about what particles are sinking. The image shows the open top of a neutral-buoyancy sediment trap (NBST) and opening through which marine snow drifts and is then collected.
