An eXpendable BathyThermograph (XBT) is a probe that is dropped from a ship and measures the temperature as it falls through the water. A resistance in the head of the probe and a very thin twin-wire, connecting the probe to the equipment on the ship, compose the electronic circuit for measuring the water temperature.
How was a bathythermograph used in WWII?
While Tex was flying through the skies, a device known as a bathythermograph, or BT, was plummeting beneath the sea surface, monitoring temperature and depth to keep U.S. Navy submarines out of enemy sonar range.
What does an XBT do?
An XBT is a small probe that is dropped over the side of a ship. As it falls through the water, it measures temperature. Small wires transmit the temperature data back to the ship where it is recorded for further analysis.
Who invented the CTD Rosette?
Neil Brown Through time, technologies to measure both temperature and salinity improved in precision and ease of use. Advancements in these individual sensors culminated in 1969 with the invention of the microprofiler, or CTD, by Neil Brown at Woods Hole Oceanographic Institution.
How much does a CTD cost?
The CTD instrument (ECS Unit Sensor) developed in this project costs around $982.00 per unit to make.
What does a rosette sampler measure?
This image shows a rosette of Niskin (seawater sampling) bottles, on a frame with instruments for measuring depth, temperature, and density (salinity), as well as the MBARI-designed ISUS (In-situ Nitrate analyzer). The CTD measures conductivity (which helps determine salinity), temperature, and depth.
What does the C in CTD stand for?
conductivity, temperature, and depth CTD stands for conductivity, temperature, and depth, and refers to a package of electronic instruments that measure these properties.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
