What is Bathythermograph used for?
The bathythermograph, or BT, also known as the Mechanical Bathythermograph, or MBT; 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).
When was Bathythermograph created?
Retired and current USGS scientists from the Great Lakes Science Center display a bathythermograph. The device was invented in the early 1900s and collected temperature information in the Great Lakes up until the 1990s.
What does an XBT measure?
temperature
An Expendable Bathythermograph (XBT) is a probe used to measure temperature throughout the water column.
What is a CTD used for?
A CTD or sonde is an oceanography instrument used to measure the electrical conductivity, temperature, and pressure of seawater (the D stands for “depth,” which is closely related to pressure). Conductivity is used to determine salinity.
What is CDT sensor?
A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water.
What is a CTD-Diver?
The CTD-Diver is a submersible datalogger for long-term uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface.
What can a CTD measure?
Conductivity, Temperature, and Depth
A CTD measures Conductivity, Temperature, and Depth. As an approximation, each 1 meter depth of water (3.28 feet) is equivalent to 1 decibar (for example, the pressure is 10 decibars at 10 meters depth).
What is CTD device?
CTD stands for conductivity, temperature, and depth, and refers to a package of electronic devices used to detect how the conductivity and temperature of water changes relative to depth.
What is a CTD winch?
It’s a abbreviated name for an instrument package which includes sensors for measuring the Conductivity, Temperature and Depth of seawater.
What is a Seabird CTD?
A CTD measures Conductivity, Temperature, and Depth. As an approximation, each 1 meter depth of water (3.28 feet) is equivalent to 1 decibar (for example, the pressure is 10 decibars at 10 meters depth).
