The WHOI Marine Mammal Center (MMC), fosters research on whales, dolphins, and seals, including their behavior, health, anatomy, and perception; methods to free entangled whales and the causes of strandings; and marine mammal populations' link to ocean conditions and plankton abundance. A particular focus is the endangered north Atlantic right ...
Marine mammals "vocalize" in a variety of ways, each of them suited to a particular behavior or situation. Dolphins, for instance, exhibit two main types of vocalization: clicks (~80K) and whistles (~120K). The "clicks" are used in echolocation to find food. Each individual dolphin also has a series of whistles (like a Morse code) distinct from ...
April 25, 2018. Deep-diving whales and other marine mammals can get the bends—the same painful and potentially life-threatening decompression sickness that strikes scuba divers who surface too quickly. A new study offers a hypothesis of how marine mammals generally avoid getting the bends and how they can succumb under stressful conditions.
Gray seals are gregarious animals—they gather in large groups on shore to breed, give birth, and molt. Female gray seals live up to 35 years and males about 25 years. Gray seals primarily hunt squid, fish, and sandeels; their main predators are humans, sharks, and orcas. Gray seal pups are born in autumn (September to November) in the eastern ...
The research was conducted under a Bahamian permit issued by the Department of Marine Resources, and under permit #1121-1900 issued by the National Marine Fisheries Service (NMFS) under the authority of the Marine Mammals Protection Act and the Environmental Protection Agency. Funding for the studies of stranded animals was provided by NMFS and ...
The North Atlantic right whale (NARW) (Eubalaena glacialis) is one of the most critically endangered whales in the world—approximately 340 of these majestic marine mammals remain, including less than 80 breeding females. NARWs are predominantly found on the Continental Shelf of the East Coast of the United States and Canada, making them ...
Sea Life Is Accumulating Pathogens. An unprecedented survey of seabirds, marine mammals, and sharks on the U.S. East Coast has revealed that marine wildlife contains a wide variety of disease-causing microbes—including many that have developed resistance to antibiotics and several that can be transmitted to humans.
In April 2010, the Woods Hole Oceanographic Institution’s Marine Mammal Center (MMC) invited the world’s experts in human diving and marine-mammal diving physiology to convene for a three-day workshop to discuss the issue of how marine mammals manage gas under pressure. Twenty-eight researchers discussed and debated the current state of ...
Six marine mammal specialists have now called for an innovative method to help balance and sort out conflicting priorities involved in strandings and forge compromises among competing interests. In a review and position paper published in the October 2007 issue of the journal Marine Mammal Science, they outline a decision tree—a systematic ...
Frequency Ranges of Marine Animal Sounds. For selected animals likely to be in or near Cape Cod coastal waters. By Kate Madin | October 5, 2012. Woods Hole Oceanographic Institution is the world's leading non-profit oceanographic research organization. Our mission is to explore and understand the ocean and to educate scientists, students ...
