Here Carmen Greto, an RV Sikuliaq technician, monitors the deployment of a conductivity, temperature, and depth (CTD) rosette. The CTD measures salinity, temperature, and pressure at multiple depths along with taking water samples. These measurements provide a baseline comparison for the newly deployed Papa instruments.
