Zhang, Dong; Liu, Huaishan; Wei, Jia; Xing, Lei (2019): 3D far-field wavelet data recorded by the ocean vertical cable collected in the south China sea in April 2017 and its simulated wave field data under this condition [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.899406

In April 2017, the Ocean University of China conducted an experiment on the northern slope of the South China Sea to measure the 3D acoustic field recorded by marine vertical cables. Experimental data were modeled by using the underwater acoustic propagation model (Van der Waals model). We present a novel graphical user interface program for simulated and measured air gun wave field data recorded by ocean vertical cable created in MATLAB R2018a. This program allows to shows the facial features of simulated and measured 3d air gun wave field, and the two match well, indicating the reliability of the Van der Waals model, and the facial features can make reasonable evaluation of air gun array intuitively. The data is stored in binary format, with detailed information described in a readme file.
