Scapa Flow is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray, South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World wars, but the facility was closed in 1956.
Flotta is a small island in Orkney, Scotland, lying in Scapa Flow. The island is known for its large oil terminal and is linked by Orkney Ferries to Houton on the Orkney Mainland, Lyness on Hoy and Longhope on South Walls. The island has a population of 80.
HMS Royal Oak was one of five Revenge-class battleships built for the Royal Navy during the First World War. Completed in 1916, the ship first saw combat at the Battle of Jutland as part of the Grand Fleet. In peacetime, she served in the Atlantic, Home and Mediterranean fleets, more than once coming under accidental attack. Royal Oak drew worldwide attention in 1928 when her senior officers were controversially court-martialled, an event that brought considerable embarrassment to what was then the world's largest navy. Attempts to modernise Royal Oak throughout her 25-year career could not fix her fundamental lack of speed and, by the start of the Second World War, she was no longer suitable for front-line duty.
HMS Vanguard was one of three St Vincent-class dreadnought battleships built for the Royal Navy in the first decade of the 20th century. She spent her career assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August several months later, her service during World War I mostly consisted of routine patrols and training in the North Sea.
The Grand Fleet was the main battlefleet of the Royal Navy during the First World War. It was established in August 1914 and disbanded in April 1919. Its main base was Scapa Flow in the Orkney Islands.
Ernest Frank Guelph Cox (1883–1959) was a British engineer, with knowledge in electrical and mechanical engineering, which he notably deployed in marine salvage. Between 1924 and 1931 his Cox & Danks Shipbreaking Co. successfully raised 35 ships of the German Imperial Navy High Seas Fleet that had been scuttled at Gutter Sound, Scapa Flow, in 1919. A tough but caring employer, after a series of fatalities and accidents to his employees, Cox sold his marine salvaging business to the Alloa Shipbreaking Company in 1932. He remained a consultant to the British Admiralty throughout his remaining career, and retired in the early 1950s after selling his profitable scrap metal business to Metal Industries Group.
HMS Edinburgh was a Town-class light cruiser of the Royal Navy, which served during the Second World War. She was one of the last two Town class cruisers, which formed the Edinburgh sub-class. Edinburgh saw a great deal of combat service during the Second World War, especially in the North Sea and the Arctic Sea, where she was sunk by torpedoes in 1942.
SMS Cöln was a light cruiser in the German Kaiserliche Marine, the second to bear this name, after her predecessor SMS Cöln had been lost in the Battle of Heligoland Bight. Cöln, first of her class, was launched on 5 October 1916 at Blohm & Voss in Hamburg and completed over a year later in January 1918. She and her sister Dresden were the last two light cruisers built by the Kaiserliche Marine; eight of her sisters were scrapped before they could be completed. The ships were an incremental improvement over the preceding Königsberg-class cruisers.
Rysa Little, commonly referred to as Rysa, is an uninhabited island in the Orkney archipelago in Scotland. It is approximately 32 hectares in area, and rises to 20 metres above sea level.
Cava is an uninhabited island in the Orkney archipelago in Scotland. It is 107 hectares (0.41 sq mi) in extent and rises to 38 metres (125 ft) above sea level. The literal meaning of the name is calf island, a terminology often used to designate a small island near to a larger one. Cava is unusual in that it includes a small peninsula joined to the main body of the island by a narrow isthmus, which is in turn called Calf of Cava.
Lyness is a village on the east coast of the island of Hoy, Orkney, Scotland. The village is within the parish of Walls and Flotta, and is situated at the junction of the B9047 and B9048.
The Barrel of Butter, formerly known as Carlin Skerry, is a skerry in Scapa Flow in the Orkney Islands.
SMS Dresden was the second and final ship of the Cöln class of light cruisers to be completed and commissioned in the Kaiserliche Marine. The ship was laid down in 1916 and launched on 25 April 1917; she was commissioned into the High Seas Fleet on 28 March 1918. She and her sister Cöln were the only two of her class to be completed; eight of her sisters were scrapped before they could be completed. The ships were an incremental improvement over the preceding Königsberg-class cruisers.
SMS Brummer was a minelaying light cruiser of the German Kaiserliche Marine; she was the lead ship of her class. Her sister ship was Bremse. Brummer was laid down at AG Vulcan's shipyard in Stettin, Germany on 24 April 1915 and launched on 11 December 1915 and completed on 2 April 1916. Armed with a main battery of four 15-centimeter (5.9 in) guns in single mounts, she carried 400 mines.
On 21 June 1919, shortly after the end of the First World War, the Imperial German Navy's High Seas Fleet was scuttled by its sailors while held off the harbour of the British Royal Navy base at Scapa Flow, in the Orkney Islands of Scotland. The fleet was interned there under the terms of the Armistice of 11 November 1918 while negotiations took place over its fate. Fearing that either the British would seize the ships unilaterally or the German government at the time might reject the Treaty of Versailles and resume the war effort, Admiral Ludwig von Reuter decided to scuttle the fleet.

Captain Guybon Chesney Castell Damant was a British royal navy officer known for his scientific research on preventing decompression illness with John Scott Haldane, his leadership over a team of divers that salvaged 44 tons of gold bullion from the wreck of HMS Laurentic between 1917 and 1924, and the covert work he and his divers performed by entering into sunken U-boats during World War I and recovering code books, ciphers, and other materials for the Naval Intelligence Division of the Royal Navy.
The following index is provided as an overview of and topical guide to Wikipedia's articles on recreational dive sites. The level of coverage may vary:
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
