Bathythermograph

Bathythermographs are instruments used in oceanography to measure and record temperature profiles of the water column. They are part of the supply class Geophysical Instruments, which includes instruments used for studying the physical properties of the Earth and its atmosphere. Bathythermographs are specifically designed to measure temperature changes with depth in the ocean.

These instruments typically consist of a temperature sensor, a pressure sensor, and a data logger. The temperature sensor measures the water temperature at different depths, while the pressure sensor measures the depth of the instrument in the water column. The data logger records the temperature and depth measurements, which can then be analyzed to study oceanographic phenomena such as thermoclines and water mass movements.

Bathythermographs are commonly used in oceanographic research, climate studies, and marine resource management. They provide valuable data for understanding the dynamics of the ocean and its impact on weather patterns, marine ecosystems, and global climate change.
