thermometric depth
测温深度
See DEPTH.
装在南森采水器上的一对闭端颠倒温度计和开端颠倒温度计,在完成颠倒动作时所处的深度称为测温深度。而温度计订正后的读数差为该深度的静水压系数。然后利用公式计算出该深度或绘制深度异常图。如钢丝绳出现倾角时,用这种方法所求得的深度为最大值。

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.
