Whitlow W.L. Au
Whitlow W. L. Au (July 31, 1940 – February 12, 2020) was a leading expert in bioacoustics specializing in biosonar of odontocetes (dolphins, porpoises, and toothed whales). He is author of the widely known book ''The Sonar of Dolphins'' (1993) and, with Mardi Hastings, ''Principles of Marine Bioacoustics'' (2008). Au was honored as a Fellow of the Acoustical Society of America in 1990 and awarded the ASA's first Silver Medal in Animal Bioacoustics in 1998. He was graduate advisor to MacArthur Fellow Kelly Benoit-Bird, who credits Au for discovering how sophisticated dolphin sonar is, developing dolphin-inspired machine sonars to separate different species of fish with the goal of protecting sensitive species, and for making numerous contributions to the description of Humpback whale song, which helped protect these whales from ship noise and ship traffic. He acted as the Chief Scientist of the Marine Mammal Research Program of the Hawaii Institute of Marine Biology at the Univers ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include some mammals (most notably Laurasiatheria) and a few birds, especially some bat species and odontocetes (toothed whales and dolphins), but also in simpler forms in other groups such as shrews, and two cave-dwelling bird groups, the so-called cave swiftlets in the genus ''Aerodramus'' (formerly ''Collocalia'') and the unrelated oilbird ''Steatornis caripensis''. Early research The term ''echolocation'' was coined in 1938 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. As Griffin described in his book, the 18th century I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sigma Tau
Sigma Tau () was an American honor society in the field of engineering. History Sigma Tau was founded at the University of Nebraska on } by fourteen faculty members and students in the College of Engineering. Sigma Tau merged with Tau Beta Pi The Tau Beta Pi Association (commonly Tau Beta Pi, , or TBP) is the oldest engineering honor society and the second oldest collegiate honor society in the United States. It honors engineering students in American universities who have shown a ... on . The officers of the Sigma Tau Fraternity at the time of the merger were: *President G. W. Forman, *Vice President H. H. Bartel Jr., *Secretary-Treasurer J. P. Colbert, and *Councillors C. W. Leihy, R. P. Moser, R. E. Peterson, and J. W. Straight Membership requirements Membership was chosen from the upper one-third of the Junior and Senior classes at recognized engineering schools. Selection from those men and women are made on the further basis of practicality and sociability. Appro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bottlenose Dolphin
Bottlenose dolphins are aquatic mammals in the genus ''Tursiops.'' They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus definitively contains two species: the common bottlenose dolphin (''Tursiops truncatus'') and the Indo-Pacific bottlenose dolphin (''Tursiops aduncus''). Others, like the Burrunan dolphin (''Tursiops (aduncus) australis''), may be alternately considered their own species or be subspecies of ''T. aduncus''. Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Their name derives from the Latin ''tursio'' (dolphin) and ''truncatus'' for their characteristic truncated teeth. Numerous investigations of bottlenose dolphin intelligence have been conducted, examining mimicry, use of artificial language, object categorization, and self-recognition. They can use tools (sponging; using marine sponges to forage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Spotted Dolphin
The Atlantic spotted dolphin (''Stenella frontalis'') is a dolphin found in warm temperate and tropical waters of the Atlantic Ocean. Older members of the species have a very distinctive spotted coloration all over their bodies. Taxonomy The Atlantic spotted dolphin was first described by Cuvier in 1828. Considerable variation in the physical form of individuals occurs in the species, and specialists have long been uncertain as to the correct taxonomic classification. Currently, just one species is recognised, but a large, particularly spotty variant commonly found near Florida quite possibly may be classified as a formal subspecies or indeed a species in its own right. Atlantic spotted dolphins in the Bahamas have been observed mating with bottlenose dolphins. Rich LeDuc has published data that suggest the Atlantic spotted dolphin may be more closely related to the bottlenose dolphins (genus ''Tursiops'') than to other members of the genus ''Stenella''. More recent studies in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaneohe Bay
Kāneohe () is a census-designated place (CDP) included in the City and County of Honolulu and located in Hawaii state District of Koolaupoko on the island of Oahu. In the Hawaiian language, ''kāne ohe'' means "bamboo man". According to an ancient Hawaiian story a local woman compared her husband's cruelty to the sharp edge of cutting bamboo; thus the place was named Kāneohe or "bamboo man". The population was 37,430 at the 2020 census. Kāneohe is the largest of several communities along Kāneohe Bay and one of the two largest residential communities on the windward side of Oahu (the other is Kailua). The commercial center of the town is spread mostly along Kamehameha Highway. From ancient times, Kāneohe was important as an agricultural area, owing to an abundance of rainfall. Today, Kāneohe is mostly a residential community, with very little agriculture in evidence. The only commercial crop of any consequence in the area is banana. Features of note are Hoomaluhia Bo ...

Coconut Island (Oahu Island)
Coconut Island, or Moku o Loe, is a 28-acre (113,000 m²) island in Kāneʻohe Bay off the island of Oʻahu in the state of Hawaiʻi, United States. It is a marine research facility of the Hawaiʻi Institute of Marine Biology (HIMB) of the University of Hawaiʻi. History In 1934–1936, Chris Holmes II, an heir to the Fleischmann yeast fortune, doubled the original island with coral rubble, sand, and earthen landfill. He established a residence with aquaria, kennels, and aviaries for his many pets. The island was converted to a rest and relaxation station for United States Navy flyers during World War II. In 1946 a group of five Los Angeles businessmen, including Edwin W. Pauley, bought the island from the estate of Chris Holmes II with the idea of converting it to the exclusive Coconut Island Club International, 1946-7, and hired architects Paul Williams, A. Quincy Jones, and C.W. Lemmon of Belt Lemmon and Lo, Architects of Honolulu to design a community of cottages, tennis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawai'i Institute Of Marine Biology
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected area a ...
