Conductivity-Temperature-Depth (CTD) Sensors

Conductivity-Temperature-Depth (CTD) sensors are scientific instruments used to measure key properties of seawater. The conductivity sensor assesses how well water conducts electricity, which indicates salinity (saltiness). The temperature sensor records the water's heat, and the depth sensor determines how deep the measurement is. These measurements help scientists understand ocean conditions, such as salinity and temperature profiles, which are important for studying ocean circulation, climate change, and marine ecosystems. CTD devices are deployed from ships or autonomous vehicles to collect data across different depths in the ocean.
