Maritime archaeology is a discipline within archaeology as a whole that specifically studies human interaction with the sea, lakes and rivers through the study of associated physical remains, be they vessels, shore-side facilities, port-related structures, cargoes, human remains and submerged landscapes. A specialty within maritime archaeology is nautical archaeology, which studies ship construction and use.
A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. Shipwrecking may be intentional or unintentional. There were approximately three million shipwrecks worldwide as of January 1999, according to Angela Croome, a science writer and author who specialized in the history of underwater archaeology.
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. The term is used mainly by recreational and technical divers. Professional divers, when diving on a shipwreck, generally refer to the specific task, such as salvage work, accident investigation or archaeological survey. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom.
USS Albacore (SS-218) was a Gato-class submarine which served in the Pacific Theater of Operations during World War II, winning the Presidential Unit Citation and nine battle stars for her service. During the war, she was credited with sinking 13 Japanese ships and damaging another five; not all of these credits were confirmed by postwar Joint Army–Navy Assessment Committee (JANAC) accounting. She also holds the distinction of sinking the highest warship tonnage of any U.S. submarine. She was lost in 1944, probably sunk by a mine off northern Hokkaidō on 7 November.
USS Snook (SS-279), a Gato-class submarine, was the first ship of the United States Navy to be named for the common snook, an Atlantic marine fish that is bluish-gray above and silvery below a black lateral line.
USS Grayback (SS-208), a Tambor-class submarine, was the first ship of the United States Navy to be named for the lake herring, Coregonus artedi. She ranked 20th among all U.S. submarines in total tonnage sunk during World War II, with 63,835 tons, and 24th in number of ships sunk, with 14. She was sunk near Okinawa on 27 February 1944. Her wreck was discovered in June 2019.
USS Bluegill (SS-242/SSK-242) was a Gato-class submarine in commission in the United States Navy from 1943 to 1946, from 1951 to 1952, and from 1953 to 1969. She was named for the bluegill, a sunfish of the Mississippi Valley.
HMAS Brisbane was one of three Perth-class guided missile destroyers to serve in the Royal Australian Navy (RAN). The United States-designed ship was laid down at Bay City, Michigan in 1965, launched in 1966 and commissioned into the RAN in 1967. She is named after the city of Brisbane, Queensland.
Imperial Japanese Navy submarines originated with the purchase of five Holland type submarines from the United States in 1904. Japanese submarine forces progressively built up strength and expertise, becoming by the beginning of World War II one of the world's most varied and powerful submarine fleets.
I-26 was an Imperial Japanese Navy B1 type submarine commissioned in 1941. She saw service in the Pacific War theatre of World War II, patrolling off the West Coast of Canada and the United States, the east coast of Australia, and Fiji and in the Indian Ocean and taking part in Operation K, preparatory operations for the Aleutian Islands campaign, and the Guadalcanal campaign, the Marianas campaign, and the Battle of Leyte Gulf. She was the first Japanese submarine to sink an American merchant ship in the war, sank the first ship lost off the coast of State of Washington during the war, damaged the aircraft carrier USS Saratoga (CV-3), sank the light cruiser USS Juneau (CLAA-52), and was the third-highest-scoring Japanese submarine of World War II in terms of shipping tonnage sunk. Her bombardment of Vancouver Island in 1942 was the first foreign attack on Canadian soil since 1870. In 1944, I-26′s crew committed war crimes in attacking the survivors of a ship she sank. She was sunk in November 1944 during her ninth war patrol.
I-21 was a Japanese Type B1 submarine which saw service during World War II in the Imperial Japanese Navy. She displaced 1,950 tons and had a speed of 24 knots (44 km/h). I-21 was the most successful Japanese submarine to operate in Australian waters, participating in the attack on Sydney Harbour in 1942 and sinking 44,000 tons of Allied shipping during her two deployments off the east coast of Australia.
USS Kittiwake (ASR-13) was a United States Navy Chanticleer-class submarine rescue vessel in commission from 1946 to 1994.
Wreck Alley is an area a few miles off the coast of Mission Beach, San Diego, California with several ships intentionally sunk as artificial reefs and as Scuba diving attractions for wreck divers.
Sinking ships for wreck diving sites is the practice of scuttling old ships to produce artificial reefs suitable for wreck diving, to benefit from commercial revenues from recreational diving of the shipwreck, or to produce a diver training site.
Shark River Reef is an artificial reef located in the Atlantic Ocean, 15.6 miles southeast of Manasquan Inlet, off of the coast of Ocean County, New Jersey. The site contains almost 4 million cubic yards of dredge rock material. Although 96% of the total reef material is rock, the site also contains numerous subway cars.
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.

Kizugawa Maru, or Kitsugawa Maruα, is a World War II-era Japanese water tanker sunk in Apra Harbor, Guam. Damaged by a submarine torpedo attack off Guam on April 8, 1944, she was towed into port for repairs. In port, she was further damaged in three separate U.S. air attacks during the Mariana and Palau Islands campaign. Deemed irreparable, Kizugawa Maru was scuttled by shore guns on June 27, 1944. The shipwreck is now a deep recreational diving site.
