Kizugawa Maru
''Kizugawa Maru'' (, ), or ''Kitsugawa Maru'', 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. History On April 8, 1944, she was part of a supply convoy from Saipan to the garrison at Woleai, when she was damaged in the port engine room by a torpedo attack by about off the eastern coast of Guam at . She was then towed to Apra Harbor for repairs by the destroyer ''Minazuki ''. Thirty-seven of her sailors were killed in the attack. In the same attack, ''Seahorse'' fatally damaged the munitions transport '' Aratama Maru'', which grounded itself in Talofofo Bay. At the time, Guam was occupied by the Japanese ...

Ships Built In Japan
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, Human migration, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%).

1941 Ships
The Correlates of War project estimates this to be the deadliest year in human history in terms of conflict deaths, placing the death toll at 3.49 million. However, the Uppsala Conflict Data Program estimates that the subsequent year, 1942, was the deadliest such year. Death toll estimates for both 1941 and 1942 range from 2.28 to 7.71 million each. Events Below, the events of World War II have the "WWII" prefix.

Underwater Diving On Guam
Underwater diving encompasses a variety of economically and culturally significant forms of diving on the U.S. island territory of Guam. Scuba diving tourism is a significant component of the island's tourist activity, in particular for visitors from Japan and South Korea. Recreational diving by Guam residents has a lesser but still substantial economic impact. Marine biologists have raised concerns about the effect of diving upon the health of some of Guam's reefs. Recreational dive sites on Guam include submerged shipwrecks, such as the double wrecks of and ''Tokai Maru'', and natural features, such as Blue Hole. Freedive spearfishing is a culturally and economically important activity for Guam residents, with a history extending to the pre-Spanish CHamoru people. Guam is well represented in local and regional spearfishing competitions. Scuba spearfishing was banned by law in March 2020, after over ten years of resistance from local fishing groups.

Wreck Diving
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. Some wreck diving involves penetration of the wreckage, making a direct ascent to the surface impossible for a part of the dive. Environment The environment of wreck diving is sunken shipwrecks and other vehicles and structures, either sunk by misfortune, acts of war, or intentionally, as targets in military exercises, to serve as artificial reefs ...

Decompression (diving)
The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth. It is also the process of elimination of dissolved inert gases from the diver's body which accumulate during ascent, largely during pauses in the ascent known as decompression stops, and after surfacing, until the gas concentrations reach equilibrium. Divers breathing gas at ambient pressure need to ascend at a rate determined by their exposure to pressure and the breathing gas in use. A diver who only breathes gas at atmospheric pressure when free-diving or snorkelling will not usually need to decompress. Divers using an atmospheric diving suit do not need to decompress as they are never exposed to high ambient pressure. When a diver descends in the water, the hydrostatic pressure, and therefore the ambient pressure, rises. Because breathing gas is supplied at ambient pressure, some of this gas dissolves into the diver's blood and is transferred by the blood to ot ...

Nitrox
Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen. It is usually used for mixtures that contain less than 78% nitrogen by volume. In the usual application, underwater diving, nitrox is normally distinguished from air and handled differently. The most common use of nitrox mixtures containing oxygen in higher proportions than atmospheric air is in scuba diving, where the reduced partial pressure of nitrogen is advantageous in reducing nitrogen uptake in the body's tissues, thereby extending the practicable underwater dive time by reducing the decompression requirement, or reducing the risk of decompression sickness (also known as ''the bends''). The two most common recreational diving nitrox mixes are 32% and 36% oxygen, which have maximum operating depths of about 110 feet (34 meters) and 95 feet (29 meters) respectively. Nitrox is used to a lesser extent in surface-supplied diving, as these advantages are reduced by the more complex logi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Guam (1941)
The Battle of Guam was an engagement during the Pacific War in World War II that took place from 8 to 10 December 1941 on Guam in the Mariana Islands between Japan and the United States. The American garrison was defeated by Japanese forces on 10 December, which resulted in an occupation until the Second Battle of Guam in 1944. Background Guam is the southernmost part of the Mariana Islands in the Pacific Ocean. It is the largest of the islands, with an area of 225 square miles. Guam's interior is rugged, with heavy tropical forests in the north of the island and wooded hills in the south. Much of the island's coastline is edged with coral reefs and cliffs, though beaches suitable for landing troops exist in the center of the west coast. Guam has a tropical climate, though December forms part of the dry season. The United States captured Guam from the Kingdom of Spain on 21 June 1898 during the Spanish–American War. The next year Spain sold the other islands in the Maria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
