THERMOMETER used to give a graphical record of the time variations of temperature.
5422
thermohygrograph
See HYGROTHERMOGRAPH.
5423
thermometer
Instrument used in the measurement of temperature.
5424

A THERMOMETER for ascertaining the temperature of SEA WATER at any DEPTH. See THER­MOMETER: PROTECTED REVERS­ING, THERMOMETER: REVERSING, THERMOMETER: UNPROTECTED REVERSING.
5425
thermometer: dry-bulb
That of the two THERMOMETERS of a PSYCHROMETER whose bulb is bare and which indicates the air temperature.
5426
thermometer: maximum
THERMOMETER used for measur­ing the highest temperature attained during a given inter­val of time, for example, a day.
5427
thermometer: minimum
THERMOMETER used for measur­ing the lowest temperature attained during a given inter­val of time, for example, a day.
5428
thermometer: protected reversing
A REVERSING THERMOME­TER enclosed in a heavy glass case to protect it from HYDROSTATIC PRESSURE.
5429

A DEEP-SEA THERMOMETER that records temperature at the desired DEPTH upon being inverted and thereafter retains its reading until returned to the first position. Reversing ther­mometers are generally used in pairs on WATER BOTTLES.
5430
thermometer: tape

A preci­sion THERMOMETER fitted in a specially designed case to clip on and against a metal TAPE in order to determine TEMPERATURE CORRECTIONS for precision BASE or TRAVERSE tape measurements.
5431
thermometer: unprotected reversing

A REVERSING THERMO­METER which is not protected against HYDROSTATIC PRES­SURE. Used in conjunc­tion with PROTECTED REVERSING THERMOMETERS to determine THERMOMETRIC DEPTH.
5432
thermometer: wet-bulb
That of the two THERMOMETERS of a PSYCHROMETER whose bulb is wet and covered by a film of pure water or ICE.
5433
thermometric depth
See DEPTH.
5434
thermometric levelling
See LEVELLING.
5435

A TRANSDUCER used to measure temperature 'in situ' of ocean BOTTOM SEDIMENTS at DEPTHS beneath the BOTTOM. Such measure­ments when combined with heat conductivity information provide a measurement of heat flow through the ocean bottom.
5436
third order triangulation
See TRIANGULATION CLASSIFI­CA­TION.
5437
three-arm protractor
See PROTRACTOR: THREE-ARM.
5438
three-point fix
See FIX.
5439
three-point fix method

One of the principal methods used on inshore HYDROGRAPHIC SURVEYS for establishing the POSITION of the SURVEY VESSEL. It involves the measurement with SEXTANTS of two angles between three known STATIONS, the middle STATION being common to both angles, and plotting the vessel's POSITION gra­phically with a THREE-ARM PROTRACTOR.
5440

The determination of the horizon­tal POSITION of a point of observation from DATA comprising two observed horizontal angles between three objects of known POSITION. The problem is solved either graphically by the use of a THREE-ARM PROTRAC­TOR, or analytically by trigonometrical computa­tion.
