The bathythermograph, or BT, also known as the Mechanical Bathythermograph, or MBT; [1] is a device that holds a temperature sensor and a transducer to detect changes in water temperature versus depth down to a depth of approximately 285 meters (935 feet).

There are various devices to measure ocean temperatures at different depths. These include the Nansen bottle, bathythermograph, CTD, or ocean acoustic tomography. Moored and drifting buoys also measure sea surface temperatures. Examples are those deployed by the Global Drifter Program and the National Data Buoy Center.
Prior to this, the Mechanical Bathythermograph (MBT) was the norm Advantages and limitations. The advantage of CTD casts is the acquisition of high-resolution data ...
Bathythermograph – Device to detect water temperature and pressure; Thermohaline circulation – Part of large-scale ocean circulation; Artificial upwelling – Oceanographic phenomenon of wind-driven motion of ocean water; Buoyancy – Upward force that opposes the weight of an object immersed in fluid
She headed the Bathythermograph Unit beginning in February 1957, analyzing ocean temperature changes at various depths, over time and space, using computers to manage the large data sets involved. [ 9 ] [ 10 ] [ 11 ] Her work had applications in tracking submarines, tuna migration, and hurricanes, among other fields. [ 8 ]
Bathymetric map of Kamaʻehuakanaloa Seamount (formerly Loihi) with isobaths. A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1]
Major contributor to redesigning the bathythermograph during World War II. His version could be used on submarines to detect the ocean thermocline. [2]
