A Minelayer is any warship, submarine or military aircraft deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range.
HMS Archer was a Long Island-class escort carrier built by the United States in 1939–1940 and operated by the Royal Navy during World War II. She was built as the cargo ship Mormacland, but was converted to an escort carrier and renamed HMS Archer. Her transmission was a constant cause of problems which led to her being withdrawn from front-line service. She was used as a stores ship and then as an accommodation ship before a refit and subsequent use as a merchant aircraft ferry ship, Empire Lagan.
USS Oglala (ID-1255/CM-4/ARG-1) was a minelayer in the United States Navy. Commissioned as Massachusetts, she was renamed Shawmut a month later, and in 1928, was renamed after the Oglala, a sub-tribe of the Lakota, residing in the Black Hills of South Dakota.
The first USS San Francisco (C-5) was a steel protected cruiser in the United States Navy. She was later named Tahoe and then Yosemite, becoming the third US Navy ship to bear the name Yosemite. She generally resembled her predecessor Newark, with a main armament of twelve 6-inch guns.
The North Sea Mine Barrage, also known as the Northern Barrage, was a large minefield laid easterly from the Orkney Islands to Norway by the United States Navy during World War I. The objective was to inhibit the movement of U-boats from bases in Germany to the Atlantic shipping lanes bringing supplies to the British Isles. Rear Admiral Lewis Clinton-Baker, commanding the Royal Navy minelaying force at the time, described the barrage as the "biggest mine planting stunt in the world's history." Larger fields with greater numbers of mines were laid during World War II.
USS Aroostook (ID-1256/CM-3/AK-44) was the Eastern Steamship Company's Bunker Hill converted for planting the World War I North Sea Mine Barrage. Bunker Hill was built in 1907 at Philadelphia, Pennsylvania for passenger service between Boston and New York City. Bunker Hill was one of three sister ships, the others being Massachusetts and Old Colony, delivered as passenger/cargo ships by William Cramp & Sons in 1907. They were among the eight ships acquired by the U.S. Navy in November 1917. Bunker Hill and Massachusetts were converted to minelayers at the Boston Navy Yard. Old Colony was used as a district scout until sent across the Atlantic and turned over to the British in 1919.
The Northern Barrage was the name given to minefields laid by the British during World War II to restrict German access to the Atlantic Ocean. The barrage stretched from the Orkney to the Faroe Islands and on toward Iceland. Mines were also laid in the Denmark Strait, north of Iceland.
The second USS Canonicus was the Southern Pacific freighter El Cid temporarily converted for planting the World War I North Sea Mine Barrage. Newport News Shipbuilding and Dry Dock Company launched El Cid at Newport News, Virginia on 7 October 1899 for service between New York City and Gulf of Mexico seaports of New Orleans and Galveston, Texas. The United States Shipping Board took control of the ship from Southern Pacific Steamship Company in 1917.
El Capitan, United States Official Number 285587, was built in 1917 by the Newport News Shipbuilding and Drydock Company at Newport News, Virginia for the Southern Pacific Company's Atlantic Steamship Lines. In 1915 the line operated from the North River piers 49–52 at the foot of 11th Street in New York to New Orleans under the flag and name of Morgan Line, which combined with the Southern Pacific's rail service from the Pacific Coast was known as the Sunset Gulf Route. During World War I the ship was purchased from the builder before delivery to the owner by the United States Shipping Board (USSB) which later turned the ship over to the United States Navy which placed her in commission as USS El Capitan (ID-1407) from 1918 to 1919. El Capitan was returned to commercial service by the Southern Pacific Company until just before the United States entry into World War II when the United States War Shipping Administration (WSA) acquired the ship, changed her registry to Panama and placed her in operation under its agent, United States Lines. El Capitan was in the Arctic convoy PQ 17 to the Soviet Union when she came under air attack on 9 July 1942, was damaged and abandoned to be sunk by torpedo just after midnight on 10 July.
The Delaware River Iron Ship Building and Engine Works, was a major late-19th-century American shipyard located on the Delaware River in Chester, Pennsylvania. It was founded by the industrialist John Roach and is often referred to by its parent company name of John Roach & Sons, or just known as the Roach shipyard. For the first fifteen years of its existence, the shipyard was by far the largest and most productive in the United States, building more tonnage of ships than its next two major competitors combined, in addition to being the U.S. Navy's largest contractor. The yard specialized in the production of large passenger freighters, but built every kind of vessel from warships to cargo ships, oil tankers, ferries, barges, tugs and yachts.

She was fitted out for United States Navy service by James Shewan & Sons at Brooklyn, New York.

While operating as part of Mine Squadron 1 out of Inverness, Scotland, from 14 July until the close of the war on 11 November 1918, Saranac laid a total of 4,782 mines:
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.
