This
spectrogram shows the result of having a vessel pass very
near an underwater hydrophone, overwhelming all other sounds
and saturating the hydrophone recording. The relatively high
frequency of the noise indicates a smaller vessel, perhaps
a fishing boat or pleasure craft, in the immediate vicinity.
