Kaiyō No.1-class Oceanographic Research Ship
The was a class of Research vessel, oceanographic research ship/weather ship of the Imperial Japanese Navy (IJN), serving during World War II. The IJN official designation was . Construction In 1938, the IJN wanted to investigate the weather and ocean currents in a potential future battlefield. ''Kaiyō No. 1''-class ships were built for the purpose. The IJN made Hokkaido Fisheries Research Institute ''San'yō Maru'' a sample for the ''Kaiyō No. 1''. All ships were deployed in the Hydrographic Department, and they were directly controlled by the Naval Ministry. Therefore, being government ships, they raised civil ensign, not the Ensign (flag), naval ensign. The crew were civil servants except for several warrant officers. All sister ships were built by Mitsubishi Heavy Industries at Shimonoseki shipyard.

Civil Ensign
A civil ensign is an ensign (maritime flag) used by civilian vessels to denote their nationality. It can be the same or different from the state ensign and the naval ensign (or war ensign). It is also known as the merchant ensign or merchant flag. Some countries have special civil ensigns for yachts, and even for specific yacht clubs, known as yacht ensigns. Most countries have only one national flag and ensign for all purposes. In other countries, a distinction is made between the land flag and the civil, state and naval ensigns. The British ensigns, for example, differ from the flag used on land (the Union Flag) and have different versions of plain and defaced Red and Blue ensigns for civilian and state use, as well as the naval ensign ( White Ensign) that can also be used by yachts of the Royal Yacht Squadron. Countries having specific civil ensigns The civil ensigns that are different from the general national flag can be grouped into a number of categories. Civ ...

National Archives Of Japan
The preserve Japanese government documents and historical records and make them available to the public. Although Japan's reverence for its unique history and art is well documented and illustrated by collections of art and documents, there is almost no archivist tradition. Before the creation of the National Archives, there was a scarcity of available public documents which preserve "grey-area" records, such as internal sources to show a process which informs the formation of a specific policy or the proceedings of various committee meetings. In accordance with the National Archives Law No.79 (1999), the core function of preserving "government documents and records of importance as historical materials" includes all material relating to (1) decision-making on important items of national policies, and (2) processes of deliberation, discussion, or consultation prior to reaching any decision-making, and the process of enforcing policies based on decisions made.

USS Gabilan (SS-252)
USS ''Gabilan'' (SS-252), a ''Gato''-class submarine, was the only ship of the United States Navy to be named for the gabilan, an eagle ray of the Gulf of California. Construction and commissioning ''Gabilan''′s keel was laid down by the Electric Boat Co., Groton, Connecticut, on 5 January 1943. She was launched 19 September 1943, sponsored by Mrs. Eleanor James, wife of Rear Admiral Jules James, and commissioned on 28 December 1943, Commander K. R. Wheland in command. First and second war patrols, April – August 1944 After shakedown out of New London, ''Gabilan'' sailed for brief antisubmarine training at Key West before transiting the Panama Canal for the Hawaiian Islands. She arrived Pearl Harbor 23 March 1944 and spent her first war patrol (21 April – 6 June) scouting the Mariana Islands gathering information for the United States invasion of those islands.

Myōjin-shō
is a submarine volcano located about 450 kilometers south of Tokyo on the Izu-Ogasawara Ridge in the Izu Islands. Volcanic activity has been detected there since 1869. Since then it has undergone more eruptions, the most powerful of which resulted in the appearance and disappearance of a small island. The name Myōjin-shō derives from a fishing boat, ''No.11 Myōjin-Maru'' of Yaizu City, Shizuoka Prefecture, the crew of which first witnessed the major volcanic eruption of 1952. Eruption of 1952-1953 The volcanic eruption from 1952 to 1953 was one of its biggest eruptions on record, with the repetitious appearance and disappearance of an island, which at one point reached over ten metres above sea level, before sinking after a major volcanic eruption in September 1953. On September 24, 1952, a survey vessel, ''Kaiyo Maru No. 5'' of the Hydrographic Department of the Maritime Safety Agency, was destroyed by the volcano, with the loss of its crew of 31 (including the nine ...

Tephra
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the fossil and its place within the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uraga, Kanagawa
is a subdivision of the city of Yokosuka, Kanagawa Prefecture, Japan. It is located on the south eastern side of the Miura Peninsula, at the northern end of the Uraga Channel, at the entrance of Tokyo Bay. History With the establishment of the Tokugawa shogunate based in Edo at the start of the 17th century, the small village of Uraga developed rapidly due to its sheltered harbor and strategic location at the entrance of Edo Bay. The area was ''tenryō'' territory under direct control of the shogunate, and the increase in maritime traffic led to the development of merchant and trading firms in the area. In 1720, the shogunate established the post of ''Uraga bugyō'', whose responsibility was to police traffic and to organize coastal defenses, and the entrances to the harbor were fortified with cannon against possible incursions by foreign ships in violation of Japan’s national isolation policy. Still, in 1812, the British whaler stopped at Uraga and took on water, food, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
