Petrel (rocket)

The Petrel was a British sounding rocket. The Petrel 1 was launched, like the Skua 1, with 3 Chick booster rockets. The Chick motors were fitted into a Booster Carriage that also carried the two parachutes that brought it back to earth for re-use. The Petrel 1 was 3.34 m long, had a diameter of 19 cm and reached a maximum altitude of 140 kilometers. It was fired from a barrel launcher approximately .

The Petrel was first flown on June 8, 1967, in South Uist. In 1977 an improved version, the Petrel 2, with a maximum height of 175 kilometers was used for the first time. The Petrel was also fired from ESRANGE at Kiruna in Sweden in 1971, and from the range on Andoya, an island off the Norwegian coast in 1973. One launcher was installed at Kiruna, while two were installed on Andoya. Both could be loaded, but only one was elevated at a time. Two launchers allowed successive firings, one as an event came up and another as it decayed.

To facilitate one experiment, a Petrel payload released gas clouds at apogee. The wife of one of the firing team members reported that strange lights were being seen in the night sky from Scotland.

Petrel (reservoir software)

Petrel is a software platform used in the exploration and production sector of the petroleum industry. It allows the user to interpret seismic data, perform well correlation, build reservoir models, visualize reservoir simulation results, calculate volumes, produce maps and design development strategies to maximize reservoir exploitation. Risk and uncertainty can be assessed throughout the life of the reservoir. Petrel is developed and built by Schlumberger.

Petrel

Petrels are tube-nosed seabirds in the bird order Procellariiformes. The common name does not indicate relationship beyond that point, as "petrels" occur in three of the four families within that group (except the albatross family, Diomedeidae). Having a fossil record that was assumed to extend back at least 60 million years, the Procellariiformes was long considered to be among the older bird groupings, other than the ratites, with presumably distant ties to penguins and loons. However, recent research and fossil finds such as Vegavis show that the Galliformes ( pheasants, grouse and relatives), and Anseriformes ( ducks, geese) are still not fully resolved.

All the members of the order are exclusively pelagic in distribution — returning to land only to breed.

The family Procellariidae is the main radiation of medium-sized true petrels, characterised by united nostrils with medium septum, and a long outer functional primary. It is dominant in the Southern Oceans, but not so in the Northern Hemisphere.

It includes a number of petrel groups, the relationships between which have finally been resolved to satisfaction.

  • The fulmarine petrels: seven species of surface predators and filter feeders, breed in high latitudes but migrate along cool currents to the north. All but Fulmarus are essentially confined to the south, Fulmarus apparently colonised the Northern Hemisphere during the Early Miocene.
    • The huge giant petrels, genus Macronectes, which are convergent with the albatrosses
    • The true fulmars, genus Fulmarus
    • Antarctic petrelThalassoica antarctica
    • Cape petrelDaption capense
    • Snow petrelPagodroma nivea
  • The prions: A specialised group of a few very numerous species, all southern. They have a small, fulmar-like form and mostly filter-feed on zooplankton.
    • Pachyptila, the prions proper
  • The procellariine petrels, larger or mid-sized species feeding on fish and molluscs which are fairly close to the prions:
    • Procellaria
    • Bulweria
  • Shearwaters: numerous species in several genera with a medium number of species.
    • Calonectris
    • Puffinus, which is in fact two rather distinct groups of larger and smaller species
    • Pseudobulweria
    • Kerguelen petrelLugensa brevirostris
  • The gadfly petrels: These are a considerable number of agile short-billed petrels in the genus Pterodroma which include the endangered Bermuda petrel or cahow and a considerable number of forms rendered extinct by human activity.

The family Hydrobatidae is the storm petrels, small pelagic petrels with a fluttering flight which often follow ships.

The family Pelecanoididae is the four species of diving petrels, genus Pelacanoides. These are auk-like small petrels of the southern oceans.

The word "petrel" comes from the Latin name for the Christian Saint Peter, and refers to the habits of certain species to hover just above the ocean waves, with their feet barely touching the water, thus giving an appearance of walking on water, as St. Peter is said to have done.

Douglas Harper's Etymology Dictionary

petrel

seabird, 1670s, pitteral, modern spelling first recorded 1703 by English explorer William Dampier (1651-1715), who wrote the bird was so called from its way of flying with its feet just skimming the surface of the water, which recalls the apostle's walk on the sea of Galilee (Matt. xiv:28); if so, it likely was formed in English as a diminutive of Peter (Late Latin Petrus). If this is folk etymology, the true source of the name is undiscovered. French pétrel (1760) probably is from English.
