Survival Threats and Conservation Efforts
Act Right Now - Save a Species
Whale and Dolphin Conservation commissioned a campaign video in the Fall of 2012 that speaks to the success of the 2008 Final Rule to Implement Speed Restrictions to Reduce the Threat of Ship Collisions with North Atlantic Right Whales. There is a 'sunset date' of December 9, 2013 that WDC, and staff from the NBWM, Audubon Society of Rhode Island, the Woods Hole Oceanographic Institution and several other interested parties would like to see lifted. This would allow the rule to stay in place for more than just five years, providing greater protection for this highly endangered species. The video can be viewed by clicking on the title 'Act Right Now - Save a Species' above.

Sounds in the Ocean–Deadly Impacts
All cetaceans use sound to communicate with other members of their species. Their sounds can travel great distances, sometimes hundreds of miles. Odontocetes (toothed whales, dolphins, porpoises) also use sound, in the form of echolocation to hunt and navigate. Their hearing structure is much more sensitive to sounds in the ocean, especially those of lower frequencies.
Unfortunately, the oceans have become a very noisy environment over the past 50 years, due to increased shipping, sonar and oil exploration via high intensity airguns. At minimum, these sounds mask the communication between animals. At worst, they are deadly, leading to mass strandings of beaked whales, dolphins and porpoises. Natural Resources Defense Council (NRDC) has created a video that summarizes these issues, with the use of animations, video footage, photographs and informative narration.
The Science of Sounds in the Ocean
Many marine organisms create sound to get their message across or find food. Snapping shrimp, red drum and bearded seals all create unique noises that will be recognized by other members of their species. The biology and physics that comprise the creation and transmission of sound are fascinating. The science of this process is explained in depth via Discovery of Sounds in the Sea (DOSITS). There are many audio clips of animal sounds and a few of anthropogenic (human-made) noises as well.
The Acoustic Ecology Institute works to increase personal and social awareness of our sound environment, through education programs in schools, regional events, and our internationally recognized website, AcousticEcology.org, a comprehensive clearinghouse for information on sound-related environmental issues and scientific research.
