The CTD/rosette contains cylindrical sampling bottles and instruments.
At every degree of longitude, CLIVAR researchers deployed the conductivity-temperature-depth (CTD)/rosette, a contraption consisting of cylindrical sampling bottles attached to a metal framework that also housed instruments for measuring temperature, salinity and depth. Samples retrieved from the rosette were taken to the mobile lab for processing.
