S15 Watergun Signature measured in Water and Air (Tank Experiment)

<ul> <li>the experiments are performed in a&nbsp;water tank (see photo)</li> <li>signatures of an S15 watergun fired at different water depths are measured</li> <li>S15 watergun has one cylindrical gun port and is fired at 130&nbsp;bar</li> <li>signatures are measured in water and&nbsp;air with B&amp;K 8105 hydrophones</li> <li>signatures in air are measured at normal incidence, directly above the source (yr = 0 cm, no &quot;yr&quot; in filename) and at different horizontal offsets from the source (varying &quot;yr&quot; as indicated in the filename)</li> <li>channel 3 is the trigger channel and indicates when the S15 watergun is fired</li> <li>recordings&nbsp;are averaged/stacked measurements of 3 shots with the S15 watergun at each source depth &quot;zs&quot;</li> <li>the filename indicates the source type (&quot;watergun_S15_&quot;), where the signal is measured (&quot;water_&quot; or &quot;air_&quot;) and the source depth&nbsp;in&nbsp;water&nbsp;(&quot;zs_cm.txt&quot;), and the horizontal offset (&quot;yr&quot;) for the specific experiments</li> <li>more information can be found in the referenced publication and the sketch of the experimental set up</li> </ul>
