There are many different sources of chemical pollution. Domestic sewage, industrial discharges, seepage from waste sites, atmospheric fallout, domestic run-off, accidents and spills at sea, operational discharges from oil rigs, mining discharges and agricultural run-off all contribute too whale, dolphin and porpoise habitat and health.
Hearing is the most important sense for cetaceans, and the ability to hear well is vital in all key aspects of their lives including finding food, navigating and social interactions. Any threat to this ability can seriously compromise individuals, populations and ultimately whole species. Human-created noise pollution comes from shipping and other vessels, military activities, fisheries anti-predation devices, ocean research, and the air-guns used in seismic testing to find oil and gas deposits. An emerging threat to whales, dolphins and porpoises are the potential impacts of marine wind farms.
Whilst many of the sources of noise pollution are localized, some recent military technologies have utilized powerful detection mechanisms that may radiate over thousands of kilometers of the ocean.
WDCS places significant emphasis on our research and negotiations to uncover, understand, control and ultimately eradicate all forms of chemical and noise pollution that threaten whales, dolphins and porpoises.
