Santa Barbara Channel
The Santa Barbara Channel is a portion of the Southern California Bight and separates the mainland of California from the northern Channel Islands. It is generally south of the city of Santa Barbara, and west of the Oxnard Plain in Ventura County. It trends east–west, is approximately long and averages about across, becoming narrowest at its easternmost extremity where Anacapa Island is about from the mainland. During the last ice age, the four northern Channel Islands, including Santa Rosa Island, were conjoined into Santa Rosae, a single island that was only five miles (8 km) off the coast. The islands are visible from the mainland on clear days. Excursion boats cross the channel, taking visitors to watch whales and visit the islands. In the perpendicular (east-west) direction, huge cargo ships and tankers occupy a major shipping lane on their way to or from the ports of Los Angeles and Long Beach. The Channel is the location of numerous oil fields, some of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
1969 Santa Barbara Oil Spill
The Santa Barbara oil spill occurred in January and February 1969 in the Santa Barbara Channel, near the city of Santa Barbara in Southern California. It was the largest oil spill in United States waters at the time. It remains the largest oil spill to have occurred in the waters off California. The source of the spill was the January 28, 1969, blow-out on Union Oil's Platform A, located from the coast in the Dos Cuadras Offshore Oil Field. Within a ten-day period, an estimated of crude oil spilled into the Channel and onto the beaches of Santa Barbara County in Southern California, fouling the coastline from Goleta to Ventura as well as the northern shores of the four northern Channel Islands. The spill had a significant impact on marine life in the Channel, killing an estimated 3,500 sea birds, as well as marine animals such as dolphins, elephant seals, and sea lions. The public outrage engendered by the spill, which received prominent media coverage in the United St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rare Species
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term ''endangered species, endangered'' or ''threatened species, threatened.'' Designation of a rare species may be made by an official body, such as a national government, state, or province. The term more commonly appears without reference to specific criteria. The International Union for Conservation of Nature does not normally make such designations, but may use the term in scientific discussion. Rarity rests on a specific species being represented by a small number of organisms worldwide, usually fewer than 10,000. However, a species having a very narrow Endemic (ecology), endemic range or Habitat fragmentation, fragmented habitat also influences the concept. Almost 75% of known species can be classified as "rare". Rare species are species with small populations. Many will move into the ...

Tomol
A ''tomol'' or ''tomolo'' (Chumash) or ''te'aat'' or ''ti'at'' (Tongva/Kizh) are plank-built boats, historically and currently in the Santa Barbara, California and Los Angeles area. They replaced or supplemented tule reed boats. The boats were between in length and in width. The Chumash refer to the ''tomol'' as the "House of the Sea" for their reliability. Double-bladed kayak-like paddles are used to propel the boat through the ocean. Some sources suggest the boats may have origins at Santa Catalina Island (California), Catalina Island and have been in use for thousands of years. Others suggest an origin on the Northern Channel Islands during the first millennium CE. The ''tomol'' has been described as "the single most technologically complex watercraft built in North America" and as being unique to "the New World." The boats are still constructed by Chumash, Tongva/Kizh, and Acjachemen people today. Construction ''Tomols'' were preferably built out of redwood that had drift ...

Chumash People
The Chumash are a Native Americans in the United States, Native American people of the central and southern coastal regions of California, in portions of what is now Kern County, California, Kern, San Luis Obispo County, California, San Luis Obispo, Santa Barbara County, California, Santa Barbara, Ventura County, California, Ventura and Los Angeles County, California, Los Angeles counties, extending from Morro Bay in the north to Malibu, California, Malibu in the south to Mt Pinos in the east. Their territory includes three of the Channel Islands (California), Channel Islands: Santa Cruz Island, Santa Cruz, Santa Rosa Island (California), Santa Rosa, and San Miguel Island, San Miguel; the smaller island of Anacapa Island, Anacapa was likely inhabited seasonally due to the lack of a consistent water source. Modern place names with Chumash origins include Malibu, California, Malibu, Nipomo, California, Nipomo, Lompoc, California, Lompoc, Ojai, California, Ojai, Pismo Beach, Point ...

Native Americans In The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the Americas, Indigenous peoples of the United States, particularly of the Contiguous United States, lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a Population history of Indigenous peoples of the Americas, precipitous decline in the size of the Native American ...

Biological Colonization
Colonisation or colonization is the spread and development of an organism in a new area or habitat. Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local community. In ecology, it is represented by the symbol ''λ'' (lowercase lambda) to denote the long-term intrinsic growth rate of a population. Surrounding theories and applicable process have been introduced below. These include dispersal, colonisation-competition trade off and prominent examples that have been previously studied. One classic scientific model in biogeography posits that a species must continue to colonize new areas through its life cycle (called a ''taxon cycle'') in order to persist. Accordingly, colonisation and extinction are key components of island biogeography, a theory that has many applications in ecology, such as metapopulations. Another factor included in this scientific model is the competition-colonisation trade off. This ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lompoc
Lompoc ( ; Chumashan ) is a city in Santa Barbara County, California, United States. Located on the Central Coast, its population was 43,834 as of July 2021. Lompoc has been inhabited for thousands of years by the Chumash people, who called the area , meaning 'lagoon' in the local Purisimeño language.Western Institute for Endangered Language Documentation: 2018: 7 The Spanish called the area after Fermín de Lasuén had established in 1787. In 1837, the Mexican government sold the area as the Rancho Lompoc land grant. Following the U.S. conquest of California, multiple settlers acquired the Lompoc Valley, including William Welles Hollister, who sold the land around the mission to the Lompoc Valley Land Company, which established a temperance colony which incorporated in 1888 as Lompoc. Lompoc is often considered a military town because it is near Vandenberg Space Force Base. Name The Western Institute for Endangered Language Documentation (WIELD) confirmed that the Chu ...

Point Arguello
Point Arguello ( Spanish: ''Punta Argüello'') is a headland on the Gaviota Coast, in Santa Barbara County, California, near the city of Lompoc. The area was first used by the United States Navy in 1959 for the launch of military and sounding rockets. It was transferred to the United States Air Force in 1964, at which time it became part of Vandenberg Air Force Base. History In 1769, the Spanish Portola expedition became the first Europeans to explore this area by land. Soldiers of the expedition named a nearby point Los Pedernales or Punta Pedernales, because they found flints there. The point was given that name on some early maps, but in 1792 British naval explorer George Vancouver dubbed it Point Arguello for José Darío Argüello, a Spanish frontier soldier who was Commandant of the Presidio of Santa Barbara and acting governor of Alta California. wrecked off Point Argüello in 1849. A High-frequency direction finding (HFDF) was established here by the Navy dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
