This CTD rosette is equiped with Niskin bottles and a wide array of sensors and instruments to collect water at various depths and create vertical profiles of the water column structure and characteristics.
This is the onboard equipment which is used for the collection of acoustic backscatter. Different frequencies of backscatter are able to detect organisms of different sizes, giving an indication of the type of animals which may be inhabiting the water column at different locations and times.
This is a picture of a drifter, which is used for our lagrangian sampling scheme to follow a parcel of water from which we sample. We put our equipment of interest, here sediment traps (which are already in the water), on a line with the drifter floating at the top. The equipment stays with the parcel of water into which it was lowered, and we locate its position at a later time (days) with satellite messages sent from the drifter.
This photo shows the placement of sediment trap tubes in their holders prior to their deployment into the water. The sediment traps are left in the water column for the duration of our sampling station (for a full cycle) to collect falling organic matter. The samples collected are used to help determine carbon export.
