Half Moon Bay (California)
Half Moon Bay is a bay of the Pacific Ocean on the coast of San Mateo County, California. The bay is approximately semi-circular, hence the name half moon, with sea access to the south. Coastal towns located there are Princeton-by-the-Sea, Miramar, El Granada, and the city of Half Moon Bay. The surfing location Mavericks is located on the outer edge of the peninsula which forms the bay. Miramar Beach is located along the shore of the bay opposite the peninsula. Marine species include flatfish, the commercially important English sole, rockfish, surfperch, Pacific herring, lingcod; and abundant winter species including starry flounder and top-smelt.''Environmental Impact Report for the Pillar Point East Harbor Master Plan'', Earth Metrics Inc., prepared for the San Mateo County Harbor District, February 1989 The bay provides an example of a logarithmic spiral beach.

Half Moon Bay, California
Half Moon Bay is a coastal city in San Mateo County, California, United States, approximately south of San Francisco. Its population was 11,795 as of the 2020 census. Immediately at the north of Half Moon Bay is Pillar Point Harbor and the unincorporated community of Princeton-by-the-Sea. Half Moon Bay is known for Mavericks, a big-wave surf location. It is called Half Moon Bay because of its crescent shape. Originally an agricultural outpost to Mission San Francisco de Asís, the town was founded in the 1840s first as San Benito, and then as is its Anglo fishing community grew, it was renamed Spanishtown. In 1874, it was again renamed to Half Moon Bay. After rail and road connections in the early 1900s, the town grew. The foggy weather of the coast made the town a popular destination for booze-running during Prohibition. The city's infrastructure is heavily integrated with the coast, including the Pillar Point Harbor, major roads and fire department. The economy of Half M ...

Sole (fish)
Sole is a fish belonging to several families. Generally speaking, they are members of the family Soleidae, but, outside Europe, the name ''sole'' is also applied to various other similar flatfish, especially other members of the sole suborder Soleoidei as well as members of the flounder family. In European cookery, there are several species which may be considered ''true soles'', but the common or Dover sole '' Solea solea'', often simply called ''the sole'', is the most esteemed and most widely available. Etymology of the word The word ''sole'' in English, French, and Italian comes from its resemblance to a sandal, Latin ''solea''. In other languages, it is named for the tongue, e.g. el, γλώσσα, german: Seezunge, nl, zeetong or ', hu, nyelvhal, es, lenguado, zh, 龍脷 ("dragon tongue"), ar, لسان الثور lisan Ath-thawr (for the common sole) meaning 'the tongue of ox' in Qosbawi accent.

Bays Of California
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Half Moon Bay State Beach
Half Moon Bay State Beach is a stretch of protected beaches in the state park system of California, United States, on Half Moon Bay. From north to south it comprises Roosevelt, Dunes, Venice, and Francis Beaches. The park was established in 1956. Recreation The broad, sandy beaches are used for sunbathing, fishing and picnicking. A campground provides accommodations for those who wish to visit longer. This Pacific Ocean beach, located immediately south of Pillar Point Harbor and the town of Princeton-by-the-Sea, is often used by surfers, who utilize its unusual waves that are influenced by reflective action from the harbor jetty. At the north end of the bay there is a county park in the lee of Pillar Point Harbor with a well-maintained trail that allows hikers and bikers access to the ocean below the point. Some of the tallest surf in California occurs offshore of Pillar Point following big storms. The area is well known as Mavericks and is famous for the annual Mavericks ...

Pilarcitos Creek
Pilarcitos Creek (Spanish for: ''Little Pillars or Pillaries Creek'') is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 15, 2011 coastal stream in San Mateo County, California, United States, that rises on the western slopes of the Santa Cruz Mountains and descends through Pilarcitos Canyon to discharge into the Pacific Ocean Half Moon Bay State Beach. The Pilarcitos Creek watershed is a significant area of ecological, cultural and economic diversity. It is a source of clean drinking water for residents of the central coast and San Francisco Bay Area and supports several natural-resource based economies – including agriculture and recreational tourism. The watershed is also experiencing increased competition for water between agricultural, domestic, recreational, commercial and environmental uses.

Logarithmic Spiral Beaches
A logarithmic spiral beach is a type of beach which develops in the direction under which it is sheltered by a headland, in an area called the ''shadow zone''. It is shaped like a logarithmic spiral when seen in a map, plan view, or aerial photograph. These beaches are also commonly referred to as half heart beach, crenulate-shaped bay, or headland-bay beach. Logarithmic spiral relation The logarithmic spiral can be determined using the equation (written in polar coordinates): :r = e^{\theta \cot \alpha} where: \theta = the angle of rotation, is located between two lines drawn from the origin to any two points on the spiral. r = the ratio of the lengths between two lines that extend out from the origin. The two lines are given as R_O and R. So r also equals the ratio R/R_O. \alpha = the angle between any line R from the origin and the line tangent to the spiral which is at the point where line R intersects the spiral. \alpha is a constant for any given logarithmic spiral. ...

Smelt (fish)
Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large Shoaling and schooling, schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt (''Hypomesus transpacificus'') found in the Sacramento Delta of California, and the eulachon (''Thaleichthys pacificus'') found in the Nort ...

Starry Flounder
The starry flounder (''Platichthys stellatus''), also known as the grindstone, emery wheel and long-nosed flounder, is a common flatfish found around the margins of the North Pacific. The distinctive features of the starry flounder include the combination of black and white-to-orange bar on the dorsal and anal fins, as well as the skin covered with scales modified into tiny star-shaped plates or tubercles (thus both the common name and species epithet), resulting in a rough feel. The eyed side is black to dark brown, while the lower side is white or cream-colored. Although classed as "righteye flounders," individuals may have their eyes on either the right or left side. They have been recorded at up to 91 cm and 9 kg. Starry flounders are inshore fish, ranging up estuaries well into the freshwater zone, to the first riffles, with young found as much as 120 km inland. In marine environments, they occur as deep as 375 m. They glide over the bottom by rippling th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lingcod
The lingcod or ling cod (''Ophiodon elongatus''), also known as the buffalo cod or cultus cod, is a fish of the greenling family Hexagrammidae. It is the only extant member of the genus ''Ophiodon. ''A slightly larger, extinct species, ''Ophiodon ozymandias'', is known from fossils from the Late Miocene of Southern California.'' ''Ophiodon elongatus'' is native to the North American west coast from Shumagin Islands in the Gulf of Alaska to Baja California, Mexico. It has been observed up to a size of and a weight of . It is spotted in various shades of gray. The lingcod is a popular eating fish, and is thus prized by anglers. Though not closely related to either ling or cod, the name "lingcod" originated because it somewhat resembles those fish. Around 20% of lingcods have blue-green to turquoise flesh.p. 298 The colour is destroyed by cooking. The colour may be due to biliverdin, but this has not been established beyond doubt.

Pacific Herring
The Pacific herring (''Clupea pallasii'') is a species of the herring family associated with the Pacific Ocean environment of North America and northeast Asia. It is a silvery fish with unspined fins and a deeply forked caudal fin. The distribution is widely along the California coast from Baja California north to Alaska and the Bering Sea; in Asia the distribution is south to Japan, Korea, and China. ''Clupea pallasii'' is considered a keystone species because of its very high productivity and interactions with many predators and prey. Pacific herring spawn in variable seasons, but often in the early part of the year in intertidal and sub-tidal environments, commonly on eelgrass, seaweed or other submerged vegetation; however, they do not die after spawning, but can breed in successive years. According to government sources, the Pacific herring fishery collapsed in the year 1993, and is slowly recovering to commercial viability in several North American stock areas. The speci ...

Surfperch
The surfperches are a family of perciform fishes, the Embiotocidae. They are mainly found in northeast Pacific Ocean (as far south as Baja California), but a few species (genera ''Ditrema'' and '' Neoditrema'') are found in the northwest Pacific, and the tule perch is found in freshwater habitats in California, United States. The largest species in the family reaches . They are viviparous fishes, in which the embryo is nourished directly by the mother, as well as the yolk. This gives the family its scientific name, from Greek ''embios'' meaning "persistent" and ''tokos'' meaning "birth". This means the mother fish gives live birth instead of laying eggs.

Sebastidae
Sebastinae is a subfamily of marine fish belonging to the family Scorpaenidae in the order Scorpaeniformes. Their common names include rockfishes, rock perches, ocean perches, sea perches, thornyheads, scorpionfishes, sea ruffes and rockcods. Despite the latter name, they are not closely related to the cods in the genus '' Gadus'', nor the rock cod, '' Lotella rhacina''. Taxonomy Sebastinae, or Sebastidae, was first formally recognised as a grouping in 1873 by the German naturalist Johann Jakob Kaup. Some authorities recognise this family as distinct from Scorpaenidae. FishBase, a finfish database generated by a consortium of academic institutions, does, but the United States Federal government's Integrated Taxonomic Information System and the 5th Edition of ''Fishes of the World'' do not, FotW classify it as a subfamily of the Scorpaenidae. Tribes and genera Sebastinae is divided into two tribes and seven genera: * Tribe Sebastini Kaup, 1873 ** '' Helicolenus'' Goode & Bea ...
