资源简介：
声学多普勒流速剖面仪（英语：Acoustic Doppler Current Profiler，缩写：ADCP）是一种用于测量水速的水声学流速计。其原理类似于声纳：ADCP向水中发射声波，水中的散射体使声波产生散射,ADCP接收散射体返还的回波信号，通过分析其多普勒效应频移以计算流速。
本数据为中国第16次南极科学考察的ADCP观测数据，调查时间为1999年12月1日-2000年3月1日，调查数据包括经度、纬度、时间、航向、航速、文件序号、平均文件记录间隔等信息。
Acoustic Doppler Current Profiler (ADCP) is a type of hydroacoustic current meter used to measure water velocity. Its operating principle is similar to that of sonar: ADCP transmits sound waves into water, where scattering bodies in the water scatter the sound waves. The ADCP receives the echo signals returned by the scattering bodies, and calculates water velocity by analyzing the Doppler frequency shift.
This dataset consists of ADCP observation data collected during the 16th Chinese National Antarctic Research Expedition. The survey was conducted from December 1, 1999 to March 1, 2000. The survey data includes information such as longitude, latitude, time, course, ship speed, file serial number, and average file recording interval.
