DECIBAR Meaning and
Definition
-
A decibar is a unit of pressure commonly used in oceanography, defined as one-tenth of a bar. The bar is a unit of pressure equal to 100,000 pascals or 100 kilopascals. Therefore, a decibar equals 10,000 pascals or 10 kilopascals. The prefix "deci-" denotes one-tenth in the International System of Units (SI).
The decibar is particularly relevant in the study of oceanic pressure because it allows for a more convenient representation of pressure changes associated with varying depths below the ocean surface. As a diver descends into the ocean, the water exerts greater pressure on their body, and this pressure increases by one decibar for every ten meters of depth. This means that at a depth of 10 meters, the pressure is approximately one decibar, at 20 meters it is around two decibars, and so on.
In oceanographic research, the decibar is a crucial unit for measuring and understanding water column dynamics, especially when it comes to ocean circulation, density changes, and the distribution of temperature and salinity. Oceanographers commonly use instruments called CTDs (Conductivity, Temperature, and Depth) to measure these properties, and the results are often reported in decibars.
In summary, a decibar is a unit of pressure equivalent to one-tenth of a bar. It is commonly used in oceanography to measure and describe pressure changes associated with different depths below the ocean surface.

Etymology of DECIBAR
The word "decibar" is derived from the combination of two terms: "deci" and "bar".
"Deci" is a prefix derived from the Latin word "decimus", meaning "one-tenth". It is used in the metric system to indicate a factor of one-tenth or one-tenth of a unit.
"Bar" is a unit of pressure used in the measurement of atmospheric pressure. It was named after the Greek word "baros", which means "weight" or "pressure". The bar is equal to 100,000 pascals (Pa), which is a standard unit of pressure in the International System of Units (SI).
Therefore, when combined, the term "decibar" literally means "one-tenth of a bar". It is commonly used to measure pressure in oceanography and meteorology, particularly in marine and atmospheric sciences.
