The mounting global shipping rates generate increasing acoustic output to the underwater environment. The deep-ocean noise levels have grown over the past four decades, which correlates with the observed increase in global shipping rates (Andrew et al., 2002, McKenna et al., 2012).Ainslie (2010) noted that an increase of 0.5 dB/a of low … WebThe paper is organised as follows. In § 2 a brief description of the experiment is given, whereas § 3 is devoted to the proper orthogonal decomposition of the near pressure field.
