Humphrey The Whale
Humphrey the Whale is a humpback whale that twice deviated from his Mexico to Alaska migration by entering San Francisco Bay. This behavior is unusual for a humpback whale, and Humphrey attracted wide media attention when entering the bay in both 1985 and 1990. Both of his bay incursions resulted in rescue by the Marine Mammal Center, based in Marin County, California, assisted by the United States Coast Guard and hundreds of other volunteers. The last sighting of Humphrey was in the vicinity of the Farallon Islands in 1991. Description The humpback whale is a mammal that belongs to the baleen whale suborder. An adult usually ranges between long and weighs approximately , or . It is well known for its breaching, its unusually long front fins, and its complex whale song. The humpback whale lives in oceans and seas around the world. Humpback whales have a stocky body with well-defined humps and black upper elements. The head and lower jaw are covered with knobs called t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humpback Whale
The humpback whale (''Megaptera novaeangliae'') is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus ''Megaptera''. Adults range in length from and weigh up to . The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song typically lasting 4 to 33 minutes. Found in oceans and seas around the world, humpback whales typically migrate up to each year. They feed in polar waters and migrate to tropical or subtropical waters to breed and give birth. Their diet consists mostly of krill and small fish, and they use bubbles to catch prey. They are promiscuous breeders, with both sexes having multiple partners. Orcas are the main natural predators of humpback whales. Like other large whales, the humpback was a target for the whaling industry. ...

Louis Herman
Louis Herman (April 16, 1930 – August 3, 2016) was an American marine biologist. He was a researcher of dolphin sensory abilities, dolphin cognition, and humpback whales. He was professor in the Department of Psychology and a cooperating faculty member of the Department of Oceanography at the University of Hawaiʻi at Mānoa. He founded the Kewalo Basin Marine Mammal Laboratory (KBMML) in Honolulu, Hawaii in 1970 to study bottlenose dolphin perception, cognition, and communication. In 1975, he pioneered the scientific study of the annual winter migration of humpback whales into Hawaiian waters. Together with Adam Pack, he founded The Dolphin Institute in 1993, a non-profit corporation dedicated to dolphins and whales through education, research, and conservation. Herman served as a member of the Sanctuary Advisory Council for the Hawaiian Islands Humpback Whale National Marine Sanctuary. In total, he has published over 120 scientific papers.

Flotilla
A flotilla (from Spanish, meaning a small ''flota'' (fleet) of ships), or naval flotilla, is a formation of small warships that may be part of a larger fleet. Composition A flotilla is usually composed of a homogeneous group of the same class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats, or minesweepers. Groups of larger warships are usually called squadrons, but similar units of non-capital ships may be called squadrons in some instances, and flotillas in others. Formations including more than one capital ship, e.g. men-of-war, battleships, and aircraft carriers, typically alongside smaller ships and support craft, are typically called fleets, each portion led by a capital ship being a squadron or task force (see reference below). A flotilla is usually commanded by a rear admiral, a commodore or a captain, depending on the importance of the command (a vice admiral would normally command a squadron). A flotilla is often divided into two or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slough (hydrology)
A slough ( or ) is a wetland, usually a swamp or shallow lake, often a backwater to a larger body of water. Water tends to be stagnant or may flow slowly on a seasonal basis. In North America, "slough" may refer to a side-channel from or feeding a river, or an inlet or natural channel only sporadically filled with water. An example of this is Finn Slough on the Fraser River, whose lower reaches have dozens of notable sloughs. Some sloughs, like Elkhorn Slough, used to be mouths of rivers, but have become stagnant because tectonic activity cut off the river's source. In the Sacramento River, Steamboat Slough was an alternate branch of the river, a preferred shortcut route for steamboats passing between Sacramento and San Francisco. Georgiana Slough was a steamboat route through the Sacramento–San Joaquin River Delta, from the Sacramento River to the San Joaquin River and Stockton. Plants and animals A slough, also called a tidal channel, is a channel in a wetland. Typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Vista Bridge
The Rio Vista Bridge (officially the Helen Madere Memorial Bridge) is a continuous truss span with a vertical-lift bridge in the middle which carries California State Route 12 across the Sacramento River at Rio Vista, California. The present bridge was completed in 1960 and is one of several moveable bridges spanning rivers in the Sacramento–San Joaquin River Delta. It is named after Helen Madere, who served as vice-mayor of Rio Vista. the bridge carries approximately 21,000 cars per day. 1919 bascule bridge The original bridge spanning the Sacramento River was built in 1918 and opened in January 1919 at a cost of . From west to east, the 1919 bridge consisted of a concrete tied arch, the Strauss double-leaf bascule, three concrete tied arches and timber A-frame trestle spans. 1960 tower bridge The 1919 bridge was replaced during seventeen years of piecewise construction. The finished 1943–1960 bridge consists of thirteen steel Warren truss spans (with one of those bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carquinez Strait
The Carquinez Strait (; Spanish: ''Estrecho de Carquinez'') is a narrow tidal strait in Northern California. It is part of the tidal estuary of the Sacramento and the San Joaquin rivers as they drain into the San Francisco Bay. The strait is long and connects Suisun Bay, which receives the waters of the combined rivers, with San Pablo Bay, a northern extension of the San Francisco Bay. The strait formed in prehistoric times, near the close of one of the past ice ages, when the Central Valley was a vast inland lake. Melting ice from the Sierra Nevada raised the water level while seismic activity created a new outlet to the Pacific Ocean, draining the lake into the ocean and exposing the valley floors. History Andrei Sarna-Wojcicki, a geologist emeritus of the US Geological Survey (USGS), estimates that the Carquinez Strait was likely formed about 640,000 to 700,000 years ago, while much of modern California was emerging from an ice age.
