Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water.
Chiloé Island also known as Greater Island of Chiloé, is the largest island of the Chiloé Archipelago off the west coast of Chile, in the Pacific Ocean. The island is located in southern Chile, in the Los Lagos Region.
Siphonophorae is an order of Hydrozoans, a class of marine organisms belonging to the phylum Cnidaria. According to the World Register of Marine Species, the order contains 175 species.
The Aysén Region, often shortened to Aysén Region or Aisén, is one of Chile's 16 first order administrative divisions. Although the third largest in area, the region is Chile's most sparsely populated region with a population of 102,317 as of 2017. The capital of the region is Coihaique, the region's former namesake.
Glaucus atlanticus is a species of small, blue sea slug, a pelagic aeolid nudibranch, a shell-less gastropod mollusk in the family Glaucidae.
Guafo Island is an island located southwest of Chiloé Island and northwest of Chonos Archipelago, Chile. This location and the prevailing westerly winds bring frequent rainstorms to the island. Ocean currents bring an abundance of fish into this area, making it one of the most productive marine areas in the Southern Pacific Ocean. Because of this, numerous marine vertebrates such as fur seals, sea lions and penguins come to the island to feed and reproduce.
The Chiloé Archipelago is a group of islands lying off the coast of Chile, in the Los Lagos Region. It is separated from mainland Chile by the Chacao Channel in the north, the Sea of Chiloé in the east and the Gulf of Corcovado in the southeast. All islands except the Desertores Islands form Chiloé Province. The main island is Chiloé Island. Of roughly rectangular shape, the southwestern half of this island is a wilderness of contiguous forests, wetlands and, in some places, mountains. The landscape of the northeastern sectors of Chiloé Island and the islands to the east is dominated by rolling hills, with a mosaic of pastures, forests and cultivated fields.
The Praya dubia, or giant siphonophore, is an invertebrate which lives in the deep sea at 700 m (2,300 ft) to 1,000 m (3,300 ft) below sea level. It has been found off the coasts around the world, from Iceland in the North Atlantic, to Chile in the South Pacific.
The western terrestrial garter snake is a western North American species of colubrid snake. At least five subspecies are currently recognized.
Polycera is a genus of sea slugs, specifically nudibranchs, shell-less marine gastropod molluscs in the family Polyceridae.
Porpita porpita, or blue button, is a marine organism consisting of a colony of hydroids found in the warmer, tropical and sub-tropical waters of the Pacific, Atlantic, and Indian oceans, as well as the Mediterranean Sea and eastern Arabian Sea. It was first identified by Carl Linnaeus in 1758, under the basionym Medusa porpita. In addition, it is one of the two genera under the suborder Chondrophora, which is a group of cnidarians that also includes Velella. The chondrophores are similar to the better-known siphonophores, which includes the Portuguese man o' war, or Physalia physalis. Although it is superficially similar to a jellyfish, each apparent individual is actually a colony of hydrozoan polyps. The taxonomic class, Hydrozoa, falls under the phylum Cnidaria, which includes anemones, corals, and jellyfish, which explains their similar appearances.
Cancellaria is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.
The sea of Chiloé is a marginal sea of the coast of Chile that is separated from the Pacific Ocean by Chiloé Island. The sea of Chiloé is connected to the open sea by Chacao Channel in the north and Gulf of Corcovado in the south. The host many of Chiloé Archipelago's islands as well as some other islands around Reloncaví Sound. The shores of the sea of Chiloé shows at various places channels, sounds and in the east also fjords. To the south beyond the Gulf of Corcovado the Sea of Chiloé gives way to Moraleda Channel.
Agalmatidae, or Agalmidae, is a family of siphonophores.
Cynanchum elegans, the white-flowered wax plant, is a plant species in the genus Cynanchum found in New South Wales in Australia. It is a threatened species.
The history of Chiloé, an archipelago in Chile's south, has been marked by its geographic and political isolation. The archipelago has been described by Renato Cárdenas, historian at the Chilean National Library, as “a distinct enclave, linked more to the sea than the continent, a fragile society with a strong sense of solidarity and a deep territorial attachment.”
Dendrogramma enigmatica is a species of siphonophore, the only one in its genus. It has been first described in 2014 on the basis of its morphology from a collection of specimens gathered in 1986. Its taxonomic affinity among animals was then unclear, but RNA from new specimens in 2016 allowed it to be identified as a siphonophore by barcoding and phylogenomics. The specimens are presumed to represent parts (bracts) of an entire siphonophore that has not been identified yet.
Bathyphysa conifera, sometimes called the flying spaghetti monster, is a bathypelagic species of siphonophore in the family Rhizophysidae.
Agalma is a genus of siphonophores in the family Agalmatidae. Siphonophores are colonial hydrozoans that feed on zooplankton.
The Antonio de Vea expedition of 1675–1676 was a Spanish naval expedition to the fjords and channels of Patagonia aimed to find whether rival colonial powers—specifically, the English—were active in the region. While this was not the first Spanish expedition to the region, it was the largest up to then, involving 256 men, one ocean-going ship, two long boats and nine dalcas. Suspicion about English bases in Patagonia was dispelled by the expedition. Spanish authorities' knowledge of western Patagonia was greatly improved by the expedition, yet Spanish interest in the area waned thereafter until the 1740s.
