中国第29次南极科学考察(2012-2013年)南大洋LADCP观测数据

LADCP（Lowered ADCP）声学多普勒海流剖面仪是一种利用声学多普勒原理测量不同深度层 (最多达128层)海流的流速、流向的系统。它可以被定点安装在浮标、船只、固定在海底或采用投放式进行测量，测量范围在1米～157米水深，对获取更真实的海水流速信息至关重要。本数据为中国第29次南极科学考察LADCP观测数据,共计63个调查站位。数据内容包括站位、经度、纬度、水深、LADCP原始数据等。

LADCP (Lowered Acoustic Doppler Current Profiler) is a system that uses the acoustic Doppler principle to measure seawater current velocity and direction across different depth layers (up to 128 layers). It can be deployed via fixed installation on buoys, vessels or seabed, or through lowered profiling measurements. The valid measurement water depth ranges from 1 meter to 157 meters, which is crucial for obtaining more realistic seawater current velocity information. This dataset contains LADCP observation data collected during China's 29th Antarctic Scientific Expedition, with a total of 63 survey stations. The data includes station information, longitude, latitude, water depth, raw LADCP data and other related contents.
