Product Highlight: Acoustic Doppler Current Profilers (ADCPs) and Conductivity Temperature and Depth Sensors (CTDs)
Acoustic Doppler Current Profilers (ADCPs) and Conductivity, Temperature, and Depth (CTD) sensors are two types of instruments commonly used in oceanography to study the physical properties of seawater, including its velocity, temperature, salinity, and depth.
ADCPs use the principle of Doppler shift to measure the speed and direction of water currents. They emit sound waves that reflect off particles or other objects in the water, and the instrument measures the change in frequency of the reflected waves to calculate the water's velocity. ADCPs can be mounted on ships or stationary structures to collect continuous data on water velocity over long periods of time. The data collected by ADCPs can be used to study the dynamics of ocean currents, the effects of tides and storms, and the distribution of sediments and pollutants in the water.
CTD sensors, on the other hand, measure the physical properties of seawater directly, including its salinity, temperature, and depth. The conductivity sensor measures the electrical conductivity of the seawater, which is related to its salinity. The temperature sensor measures the temperature of the water, and the depth sensor measures the depth of the instrument in the water. These measurements can be combined to calculate the water's density and other important properties. CTD sensors are often used in conjunction with other instruments, such as ADCPs, to study ocean currents, water masses, and other aspects of oceanography.

Both ADCPs and CTD sensors are crucial instruments for studying the ocean, and they are often used together to provide a more complete picture of the physical properties of seawater. The data collected by these instruments are used in a wide range of applications, including climate studies, ocean circulation models, and marine resource management. They are also used to study ocean acidification and other changes in the chemistry of seawater, which can have important implications for marine ecosystems and the global climate.
Overall, ADCPs and CTD sensors are highly specialized and sophisticated instruments that provide scientists with important data to help them better understand the ocean and its role in the global climate system.
