Raw and processed LADCP profiles from expedition PS117 (Weddell Sea)

This dataset contains raw and processed lowered acoustic Doppler current profiler (LADCP) data acquired during expedition PS117 in the Weddell Sea. The LADCP system consisted of two 300 kHz RDI Workhorse Monitor ADCPs mounted on the CTD-rosette frame. Near the sea surface, shipboard ADCP (SADCP) data were used to constrain the LADCP velocity solutions. The dataset includes the original raw LADCP files together with the corresponding processed velocity profiles. Data processing was performed using the GEOMAR LADCP software package (version 10.21, 2015-05-17). Additional details on the expedition, instrumentation, and processing methodology can be found at https://doi.org/10.2312/BzPM_0732_2019.本数据集包含威德尔海（Weddell Sea）科考航次PS117期间获取的原始与处理后的下放式声学多普勒海流剖面仪（lowered acoustic Doppler current profiler，LADCP）数据。 该LADCP系统由两台安装于CTD采水器架（CTD-rosette frame）上的300 kHz RDI Workhorse Monitor型声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP）组成。 在近海面区域，采用船载声学多普勒海流剖面仪（Shipboard ADCP，SADCP）数据对LADCP流速解算结果进行约束。 本数据集包含原始LADCP文件及对应的处理后流速剖面数据。数据处理工作采用GEOMAR LADCP软件包（版本10.21，2015-05-17）完成。 有关本次科考航次、仪器设备及处理方法的更多细节，可访问https://doi.org/10.2312/BzPM_0732_2019获取。
