Figure 14. A container ship, with considerable energy above 4Hz, dominated the noise field near the sensor on 25 December. The ship starts raising noise levels at the site 6hr before its closest approach to the JOIDES Resolution, although it is ~180 km away (traveling at 17 kt). Root-mean-square (RMS) levels in octave bands are given in decibels relative to a m/sec^2.
