Brooks Island
Brooks Island Regional Preserve includes both the of Brooks Island above the low-tide line and of the surrounding bay. The only public access to the island is via an East Bay Regional Park District naturalist tour. Brooks Island is a mostly flat strip of land extending from a round hill, named Jefferds Hill, which peaks at in San Francisco Bay, located just south of the Richmond Inner Harbor in Richmond, California. Originally named as ''Isla de Cármen'' by a Spanish explorer, the island appeared as "Brooks Island" on maps from 1850 onward. The eponymous Brooks has never been identified. It has also been called Sheep Island and Rocky Island at various times. The island was bought by the regional parks district in 1968, and was opened to the public in 1988. Access is now available through ranger-led guided tours. History Ohlone period On the island are the remains of several shellmounds left from prolonged occupation by Native Americans, most likely people from the Ohlone tr ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Common Seal
The harbor (or harbour) seal (''Phoca vitulina''), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinnipeds, pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic Ocean, Atlantic, Pacific Oceans, Baltic Sea, Baltic and North Seas. Harbor seals are brown, silvery white, tan, or gray, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and a mass of up to . Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. Males may fight over mates under water and on land. Females bear a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadwalader Ringgold
Cadwalader Ringgold (August 20, 1802 – April 29, 1867) was an officer in the United States Navy who served in the United States Exploring Expedition, later headed an expedition to the Northwest and, after initially retiring, returned to service during the Civil War. Life and early career Cadwalader Ringgold was born August 20, 1802, in Washington County, Maryland, at Fountain Rock, the family estate. His mother was Maria Cadwalader (1776–1811), daughter of John Cadwalader (1742–1786), who was a general during the American Revolutionary War. Some sources spell his first name with two "l"s.

San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland. Home to approximately 7.76 million people, Northern California's nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a comp ...

Rancho San Pablo
Rancho San Pablo was a land grant in present-day Contra Costa County, California given in 1823 by Governor Luís Antonio Argüello to Francisco María Castro (1775–1831), a former soldier at the San Francisco Presidio and one-time ''alcalde'' of the Pueblo of San José. The grant was reconfirmed by Governor José Figueroa in 1834 to the heirs of Francisco Castro, including Víctor Castro. The San Pablo grant covered what is now Richmond, San Pablo, El Cerrito, and Kensington in western Contra Costa County. History The land had previously been grazing land for cattle belonging to the Misión Dolores, but was secularized by the new Mexican republic. Francisco Maria Castro lived there with his wife María Gabriela Berreyesa and family from the late 1820s until his death in 1831. Governor of Mexican Alta California, Juan Alvarado, married one of the Castro daughters in 1839. After his term as governor was completed, they retired to her family property on Rancho San Pablo. ...

Juan Manuel De Ayala
Juan Manuel de Ayala y Aranza (28 December 1745 – 30 December 1797) was a Spanish naval officer who played a significant role in the European exploration of California, since he and the crew of his ship the ''San Carlos'' are the first Europeans known to have entered the San Francisco Bay. Having sailed from the Port of San Blas Nayarit Mexico. Biography Ayala was born in Osuna, Andalucía, Spain. He entered the Spanish navy on the 19 September 1760, and rose to achieve the rank of captain by 1782. He retired (on full pay on account of his achievements in California) on March 14, 1785. In the early 1770s, the Spanish royal authorities ordered an exploration of the north coast of California, "to Ascertain if there were any Russian Settlements on the Coast of California, and to Examine the Port of San Francisco". Don Fernando Rivera y Moncada had already marked the point for a mission in what is now San Francisco, and a land expedition to establish Spanish rule over the area, u ...

Clam
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned ...

Oyster
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed (cooked or raw), and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. Etymology The word ''oyster'' comes from Old French , and first appeared in English during the 14th century. The French derived from the Latin , the feminine form of , which is the latinisation of the Ancient Greek () 'oyster'. Compare () 'bone'. Types True oysters True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly belong t ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishhook
A fish hook or fishhook, formerly also called angle (from Old English ''angol'' and Proto-Germanic ''*angulaz''), is a hook used to catch fish either by piercing and embedding onto the inside of the fish mouth (angling) or, more rarely, by impaling and snagging the external fish body. Fish hooks are normally attached to a line, which tethers the target fish to the angler for retrieval, and are typically dressed with some form of bait or lure that entices the fish to swallow the hook out of its own natural instinct to forage or hunt. Fish hooks have been employed for millennia by fishermen to catch freshwater and saltwater fish. There is an enormous variety of fish hooks in the world of fishing. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. Fish hooks are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, ...

Herring
Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of ''Clupea'' (the type genus of the herring family Clupeidae) are recognised, and comprise about 90% of all herrings captured in fisheries. The most abundant of these species is the Atlantic herring, which comprises over half of all herring capture. Fish called herring are also found in the Arabian Sea, Indian Ocean, and Bay of Bengal. Herring played an important role in the history of marine fisheries in Europe, and early in the 20th century, their study was fundamental to the development of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are also known as "sil ...

Harpoon
A harpoon is a long spear-like instrument and tool used in fishing, whaling, seal hunting, sealing, and other marine hunting to catch and injure large fish or marine mammals such as seals and whales. It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the projectile to catch the animal. A harpoon can also be used as a weapon. Certain harpoons are made with different builds to perform better with the type of target being aimed at. For example, the Inuit have short, fixed foreshaft harpoons for hunting seals at their breathing holes while loose shafted ones are made for attaching to the game thrown at. History In the 1990s, harpoon points, known as the Semliki harpoons or the Katanda harpoons, were found in the Katanda_Territory, Katanda region in Zaire (called the Democratic Republic of the Congo today). As the earliest known harpoons, these weapons were made and used 90, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
