中国第7次北极科学考察(2016年)走航ADCP观测数据

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7次北极科学考察的走航ADCP观测数据，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 for short) is a type of hydroacoustic current meter used to measure water flow velocity. Its working principle is similar to sonar: ADCP emits sound waves into water, where scatterers in the water scatter the sound waves. ADCP then receives the echo signals returned by the scatterers, and calculates the water flow velocity by analyzing the Doppler frequency shift.

This dataset consists of underway ADCP observation data from the 7th Chinese National Arctic Scientific Expedition. The survey data includes information such as longitude, latitude, time, course, ship speed, file serial number, and average file recording interval.
