Bathythermograph Head

A Bathythermograph (BT) Head is a type of instrument used in geophysics to measure the temperature and depth of water in the ocean. It is typically used in oceanographic research and surveys to gather data on the vertical temperature profile of the water column.

The BT Head is designed to be attached to a cable or a towed body, which is then lowered into the water. As the instrument is lowered, it measures the temperature at various depths and transmits the data back to a recording device on the surface.

The data collected by the BT Head is important for understanding the thermal structure of the ocean, which can have significant implications for climate studies, ocean circulation models, and marine life research. By measuring the temperature at different depths, scientists can gain insights into the movement of water masses, the presence of thermoclines (sharp temperature gradients), and the distribution of heat in the ocean.

In summary, a Bathythermograph Head is a geophysical instrument used to measure the temperature and depth of water in the ocean. It plays a crucial role in oceanographic research and helps scientists understand the thermal structure of the ocean.
