sonde|sɒnd|
[Fr., ‘sounding-line, sounding’.]
a. A radiosonde or similar device that is sent aloft to transmit or record information on conditions in the atmosphere. Orig. only as the second element in Combs. (as ballon-sonde, ionosonde, radiosonde, etc.).
1901[see ballon-sonde]. 1937[see radiosonde]. 1943P. A. Anderson et al. Captive Radiosonde & Wired Sonde Techniques (U.S. Nat. Defense Res. Council Project P.D.R.C.-647, Rep. No. 3) 4 When the sonde is moved to a new altitude, a pause of 10–30 seconds is adequate to establish equilibrium readings on the meters. 1949Sci. Progr. XXXVII. 490 A direct method of sounding may provide information on solar spectra from which data on the atmosphere above the highest level reached by the sonde may be derived. 1969McIntosh & Thom Essent. Meteorol. vii. 111 More recently, ozone sondes have been used to measure the vertical distribution of ozone. 1975Nature 1 May 20/2 A seventh aircraft was used to drop sondes from 40,000 feet and obtain additional vertical profiles of wind and temperature.
b. An instrument probe for transmitting information about its surroundings underground or under water.
1952Bull. Amer. Assoc. Petroleum Geologists XXXVI. 310 The application of the limestone sonde log to the determination of the porosity profile of wells. 1962Research XV. 298/1 This deflection increases as the sonde continues to enter the [coal] seam. 1962[see re-entry 2 d]. 1975G. Anderson Coring vii. 124 The SP log is a measurement of the electrical potential energy in the mud around the sonde as compared with a reference electrode grounded at the surface. |
