Conductivity, Temperature, Depth (CTD) Sensors / Profilers

A Conductivity, Temperature, Depth (CTD) Sensor, or CTD Profiler, collects data on water temperature, salinity, and pressure at different depths in the ocean. Typically deployed as part of a profiling system that is incrementally lowered into the water column, data collected by the CTD sensor provides valuable insights into oceanographic processes such as water mass formation, mixing, and currents, as well and the distribution of nutrients and gases, which is vital for understanding marine ecosystems and climate dynamics.
