Shell Beach, La Jolla
Shell Beach, La Jolla is a small beach in La Jolla, a community of San Diego, California, United States. The beach is accessed via a flight of concrete steps that start at the south end of Ellen Browning Scripps Park. This beach is located immediately north of Children's Pool Beach, south of Boomer Beach, and also south of La Jolla Cove. During extreme low tides, the southern end of Shell Beach has an interesting tidepool-like area, with many marine creatures visible. Because of the presence of reef structures and rip currents that can be hazardous to scuba divers, the San Diego Council of Divers provides a "Rocks, Rips and Reefs" tour for the area. Visible to the south a short distance out from Shell Beach is Seal Rock, which often has a number of harbor seals resting on it. There is presence of sea glass on the beach.

Scuba Diver
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breath ...

Beaches Of Southern California
A beach is a landform alongside a body of water which consists of loose particles. The particles composing a beach are typically made from rock, such as sand, gravel, shingle, pebbles, etc., or biological sources, such as mollusc shells or coralline algae. Sediments settle in different densities and structures, depending on the local wave action and weather, creating different textures, colors and gradients or layers of material. Though some beaches form on inland freshwater locations such as lakes and rivers, most beaches are in coastal areas where wave or current action deposits and reworks sediments. Erosion and changing of beach geologies happens through natural processes, like wave action and extreme weather events. Where wind conditions are correct, beaches can be backed by coastal dunes which offer protection and regeneration for the beach. However, these natural forces have become more extreme due to climate change, permanently altering beaches at very rapid r ...

List Of Beaches In San Diego County
This is a list of beaches in San Diego County, located in Southern California in the United States. The beaches are listed in order from north to south, and they are grouped (where applicable) by the community in which the beach is situated. Some beaches in the San Diego area are long continuous stretches of sandy coastline, others, like many of the beaches in the Village of La Jolla (which was built on a large rocky promontory), are small sand beaches within rocky coves or between rocky points. A number of beaches in the San Diego area have cliffs behind them, usually composed of rather soft sandstone; some other beaches front freshwater lagoons where rivers run into the coast. Beaches in North County This list of beaches in San Diego's North County is arranged from north to south; the beaches are grouped by the communities in which they occur. Although in some areas there may be a continuous long stretch of sand along several miles of coastline, especially so during low ti ...

Sea Glass
Sea glass and beach glass are naturally weathered pieces of glass, which often have the appearance of tumbled stones. "Sea glass" is physically and chemically weathered glass found on beaches along bodies of salt water. These weathering processes produce natural frosted glass. "Genuine sea glass" can be collected as a hobby and is used for decoration, most commonly in jewelry. "Beach glass" comes from fresh water and is often less frosted in appearance than sea glass. Sea glass takes 20 to 40 years, and sometimes as much as 100 to 200 years, to acquire its characteristic texture and shape. It is also colloquially referred to as "drift glass" from the longshore drift process that forms the smooth edges. In practice, the two terms are used interchangeably. Formation Sea glass begins as normal shards of broken glass that are then persistently tumbled and ground until the sharp edges are smoothed and rounded. In this process, the glass loses its slick surface but gains a frost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbor 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 pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic, Pacific Oceans, 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 single pup after a nine-month gestation, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rip Current
A rip current, often simply called a rip (or misleadingly a ''rip tide''), is a specific kind of water current that can occur near beaches with breaking waves. A rip is a strong, localized, and narrow current of water which moves directly away from the shore, cutting through the lines of breaking waves like a river running out to sea. The current in a rip is strongest and fastest next to the surface of the water. Rip currents can be hazardous to people in the water. Swimmers who are caught in a rip current and who do not understand what is happening, or who may not have the necessary water skills, may panic, or they may exhaust themselves by trying to swim directly against the flow of water. Because of these factors, rip currents are the leading cause of rescues by lifeguards at beaches, and in the United States, they are the cause of an average of 46 deaths by drowning per year. A rip current is not the same thing as undertow, although some people use the term incorrectly whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tidepool
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. Many of these pools exist as separate bodies of water only at low tide. Many tide pool habitats are home to especially adaptable animals that have engaged the attention of naturalists and marine biology, marine biologists, as well as philosophical essayists: John Steinbeck wrote in ''The Log from the Sea of Cortez'', "It is advisable to look from the tide pool to the stars and then back to the tide pool." Zones from shallow to deep The rocky shoreline exhibits zonation as a feature of the shoreline. Tidal movements of water creates zonation patterns along rocky shores from high to low-tide. The area above the high-tide mark is the supralittoral zone which is virtually a Ecoregion#Terrestrial, terrestrial environment. The area around the high-tide mark is known as the intertidal fringe. Between the high and low-tide marks is the intertidal or littoral zone. Below the low-tid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Jolla Cove
La Jolla Cove is a small cove with a beach that is surrounded by cliffs in La Jolla, San Diego, California. Point La Jolla forms the south side of the cove. The area is protected as part of a marine reserve and is popular with snorkelers, swimmers and scuba divers. The swells that often roll in from the open ocean can be large and strong. The water temperature is often a little colder than the average San Diego beach. While the beach has only a small dry sand area at high tide, during very low tides, tide pools are revealed at the cove. California sea lions can be found in the waters of the Cove and hauling out, temporarily leaving the water to rest on its beaches, cliffs, and bluffs. Similar to the events of the Pacific harbor seals at Children's Pool Beach, there is controversy concerning the interactions of people with the sea lions. Access Free public parking is extremely limited and is all on-street; there are also paid parking garages in the area. From the park at ...
