CTD (Conductivity, Temperature, Depth) Profiler

A CTD (Conductivity, Temperature, Depth) profiler is a scientific instrument used in oceanography to measure three important characteristics of seawater: its conductivity, temperature, and depth. Conductivity indicates the amount of salt in the water, helping scientists understand salinity. Temperature affects the water's density and circulation. Depth measures how deep the water column is. Typically deployed from a ship, the CTD collects data as it descends through the water, providing valuable insights into ocean conditions, aiding research on climate change, marine ecosystems, and ocean circulation patterns.
