SWellEx-96 Experiment Acoustic Data

The SWellEx-96 Experiment was conducted between May 10 and 18, 1996, approximately 12 km from the tip of Point Loma near San Diego, California. Acoustic sources, towed from the R/V Sproul, transmitted various broadband and multitone signals at frequencies between 50 and 400 Hz. The acoustic sensors deployed in SWellEx-96 include a vertical line array (VLA) and a tilted line array (TLA), deployed by the FLoating Instrument Platform (R/P FLIP), and two horizontal line arrays (HLA) known as the All Optical Deployable System (AODS) installed on the seafloor and distinguished as northern and southern HLA's. Details regarding the transmitted and received acoustic signals for two source tow events known as Event S5 and Event S59 are contained in this data set. Event S5 is a source tow along an isobath devoid of loud interferers. Event S59 is a similar source tow along an isobath but with a loud interferer - a nearby surface ship - present throughout the duration of the event.

SWellEx-96实验于1996年5月10日至18日在加利福尼亚州圣迭戈附近、距洛马角尖端约12公里的海域开展。由斯普罗尔号（R/V Sproul）科考船拖曳的声学声源，发射了频率介于50至400 Hz之间的多种宽带与多音信号。本次实验部署的声学传感器包括由浮动仪器平台（R/P FLIP）布放的垂直线阵（VLA）与倾斜线阵（TLA），以及两套隶属于全光学可部署系统（AODS）的海底水平线阵（HLA），该两套阵列分别以北部水平线阵与南部水平线阵相区分。本数据集涵盖两场被标记为事件S5与事件S59的源拖曳作业的发射与接收声学信号细节。其中，事件S5为沿等深线开展的源拖曳作业，作业区域无强干扰源；事件S59为沿等深线开展的同类源拖曳作业，但全程存在一处强干扰源——一艘邻近的水面舰艇。
