The ocean is a vast and complex system that requires constant monitoring and research. One of the tools used to study the ocean is the bathythermogram. This article will define and explore the meaning of bathythermogram, its origin, and associations.
Definitions
A bathythermogram is a graph or chart that shows the temperature changes in the ocean as a function of depth. It is a tool used to measure the thermal structure of the ocean and is often used to study ocean currents and the movement of heat through the ocean.
Origin
The term bathythermogram is derived from the Greek words “bathy” meaning deep and “thermo” meaning heat. The concept of using temperature measurements to study the ocean dates back to the early 1900s, but the term bathythermogram was not coined until the 1940s.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, a bathythermogram is “a record of temperature changes with depth in a body of water.” The Oxford English Dictionary defines it as “a graph or chart showing the variation of temperature with depth in a body of water.”
Associations
Bathythermograms are often used in oceanography to study the thermal structure of the ocean and the movement of heat through the ocean. They can also be used to study ocean currents and the distribution of nutrients and oxygen in the ocean.
Synonyms
Synonyms for bathythermogram include temperature-depth profile, thermograph, and temperature-salinity diagram.
Antonyms
There are no direct antonyms for bathythermogram, but some related terms include bathymetry (the measurement of the depth of the ocean floor) and hydrography (the study of the physical features and conditions of the ocean).
The same root words
Other terms that use the root words “bathy” and “thermo” include bathymetry, bathypelagic (referring to the deep ocean), and thermocline (a layer in the ocean where the temperature changes rapidly with depth).
Example Sentences
- The oceanographer used a bathythermogram to study the thermal structure of the ocean.
- The bathythermogram showed a steep thermocline at 100 meters.
- The temperature-depth profile revealed the presence of a cold water upwelling.
In conclusion, a bathythermogram is a graph or chart that shows the temperature changes in the ocean as a function of depth. It is a valuable tool for studying the thermal structure of the ocean and the movement of heat through the ocean. The term bathythermogram is derived from the Greek words “bathy” meaning deep and “thermo” meaning heat, and it has been used by oceanographers since the early 1900s.
