Oceanic is an American manufacturer of scuba gear. It was founded by Bob Hollis in 1972 and is based in San Leandro , California , United States. [ 1 ] Its products include dive computers , rebreathers and a novel diving mask incorporating a heads-up-display of information.
A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of decompression sickness.
Karl E. Huggins is an American decompression researcher and author of a set of air decompression tables for reduced risk and multi-level repetitive diving based on the US Navy tables modified to avoid Doppler ultrasound detectable vascular bubble production.
The Orca Edge was an early example of a dive computer that ran a real time algorithm. [2] Designed by Craig Barshinger , Karl E. Huggins and Paul Heinmiller, the Edge did not display a decompression plan, but instead showed the ceiling or the so-called "safe-ascent-depth" and a graphic display of calculated tissue gas loadings.
Aeris (dive gear) – American brand of scuba equipment Originally a brand of American Underwater Products, founded in 1998, and merged into a sister-brand, Oceanic, in 2014. Aeris brand covered a wide range of recreational scuba equipment, including regulators, dive computers, buoyancy compensators, harnesses, masks, fins, and snorkels.
The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of John Scott Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
Oceaneering was founded in 1964 with the incorporation of World Wide Divers, Inc., one of three companies who merged in 1969 to operate under the name Oceaneering International, Inc. The merged companies were World Wide Divers, Inc. (Morgan City, LA), California Divers, Inc. (Santa Barbara, CA), and Can-Dive Services Ltd (North Vancouver, BC). [3]
Alvin, first of its ship class of deep submergence vehicle (DSV), was built to dive to 2,440 metres (8,010 ft). Each of the Alvin-class DSVs have different depth capabilities. However, Alvin is the only one seconded to the National Oceanic and Atmospheric Administration (NOAA), with the others staying with the United States Navy.
