Descrição/Abstract
The oceans are often thought of as a silent world. However, in reality the oceans are filled with sounds from both natural and anthropogenic (i.e. human generated) sound sources. In fact, during the last five decades, ocean ambient noise levels have increased with at least 10-12 dB within the 30-50 Hz frequency band. This frequency band falls within the hearing range of baleen whales, of which 42% of all species are endangered. As a result, there is a currently growing concern that anthropogenic sounds in the marine environment potentially have a substantial impact on marine organisms.
