360˚ Video: Deploying a CTD Rosette

The crew of RV Thomas G. Thompson deploys a conductivity, temperature, depth (CTD) sensor with a rosette of Niskin sampling bottles in July 2019 on the Shelfbreak Productivity Interdisciplinary Research Operation at the Pioneer Array (SPIROPA) expedition.

A CTD is the primary tool oceanographer use to determine the essential physical properties of seawater. It gives scientists a precise and comprehensive charting of the distribution and variation of water temperature, salinity, and density that helps to understand how the oceans affect life.
