Meteor (1915)
''Meteor'' was a German survey vessel, noted for her survey work in the Atlantic Ocean between 1925 and 1927. Handed over to the Soviet Union following World War II, the ship was renamed ''Ekvator''. Her ultimate fate is not known. Design and construction Her keel was laid at the Kaiserliche Werft at Danzig in February 1914 and ''Meteor'' was launched in January 1915. Originally intended to become a gunboat for the Imperial German Navy's colonial service she was not finished during the First World War due to limited need for lightly armed vessels. After the war the uncompleted hull was tugged to Wilhelmshaven for outfitting work at the Reichsmarinewerft. She was outfitted as a survey vessel and early sonar equipment was fitted. The ship had a steel hull with two propellers each driven by a triple-expansion steam engine. Additionally she had a brigantine rig to boost range. Career ''Meteor'' was commissioned as a military ship with the Reichsmarine but spent most of her lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichsmarine
The ''Reichsmarine'' ( en, Realm Navy) was the name of the German Navy during the Weimar Republic and first two years of Nazi Germany. It was the naval branch of the ''Reichswehr'', existing from 1919 to 1935. In 1935, it became known as the ''Kriegsmarine'' (War Navy), a branch of the ''Wehrmacht''; a change implemented by Adolf Hitler. Many of the administrative and organizational tenets of the ''Reichsmarine'' were then carried over into the organization of the ''Kriegsmarine''. ''Vorläufige Reichsmarine'' The ''Vorläufige Reichsmarine'' ( en, Provisional Realm Navy) was formed after the end of World War I from the Imperial German Navy. The provisions of the Treaty of Versailles restricted the German Navy to 15,000 men and no submarines, while the fleet was limited to six pre-dreadnought battleships, six light cruisers, twelve destroyers, and twelve torpedo boats. Replacements for the outdated battleships were restricted to a maximum size of 10,000 tons. ''Reichsmarine'' T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple-expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Barracks Ship
A barracks ship or barracks barge or berthing barge, or in civilian use accommodation vessel or accommodation ship, is a ship or a non-self-propelled barge containing a superstructure of a type suitable for use as a temporary barracks for sailors or other military personnel. A barracks ship, a military form of a dormitory ship, may also be used as a receiving unit for sailors who need temporary residence prior to being assigned to their ship. The United States Navy used to call them Yard Repair Berthing and Messing with designations YRBM and YRBM(L) and now classes them as either Auxiliary Personnel Barracks (APB) or Auxiliary Personnel Lighter (aka barge) (APL). Early use Barrack ships were common during the era of sailing ships when shore facilities were scarce or non-existent. Barrack ships were usually hulks. At times, barrack ships were also used as prison ships for convicts, prisoners of war or civilian internees. Use in World War II ''Barracks ships'' in the comb ...

Kiel
Kiel () is the capital and most populous city in the northern Germany, German state of Schleswig-Holstein, with a population of 246,243 (2021). Kiel lies approximately north of Hamburg. Due to its geographic location in the southeast of the Jutland peninsula on the southwestern shore of the Baltic Sea, Kiel has become one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel mutiny, Kiel Mutiny, when sailors refused to board their vessels in protest against Germany's further participation in World War I, resulting in the abdication of the Wilhelm II, German Emperor, Kaiser and the formation of the Weimar Republic. The Olympic sailing competitions of the 1936 Summer Olympics, 1936 and the 1972 Summer Olympics#Venues, 1972 Summer Olympics were held in the Bay of Kiel. Kiel has also been one of the traditional homes of the German Nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norway
Norway, officially the Kingdom of Norway, is a Nordic country in Northern Europe, the mainland territory of which comprises the western and northernmost portion of the Scandinavian Peninsula. The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway. Bouvet Island, located in the Subantarctic, is a dependency of Norway; it also lays claims to the Antarctic territories of Peter I Island and Queen Maud Land. The capital and largest city in Norway is Oslo. Norway has a total area of and had a population of 5,425,270 in January 2022. The country shares a long eastern border with Sweden at a length of . It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the se ...

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tender Ship
A ship's tender, usually referred to as a tender, is a boat, or a larger ship, used to service or support other boats or ships. This is generally done by transporting people or supplies to and from shore or another ship. A second and distinctly different meaning for ''tender'' is small boats carried by larger vessels, to be used either as lifeboats, or as transport to shore, or both. Tenders as smaller craft For a variety of reasons, it is not always advisable to try to tie a ship up at a dock; the weather or the sea might be rough, the time might be short, or the ship too large to fit. In such cases tenders provide the link from ship to shore, and may have a very busy schedule of back-and-forth trips while the ship is in port. On cruise ships, lifeboat tenders do double duty, serving as tenders in day-to-day activities, but fully equipped to act as lifeboats in an emergency. They are generally carried on davits just above the promenade deck, and may at first glance appear t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Meteor Seamount
The Great Meteor Seamount, also called the Great Meteor Tablemount, is a guyot and the largest seamount in the North Atlantic with a volume of . It is one of the Seewarte Seamounts, rooted on a large terrace located south of the Azores Plateau. The crust underlying Great Meteor has an age of 85 million years, deduced from the magnetic anomaly 34 (An34) at this location. The shallow and flat summit of the Great Meteor Seamount, ranging between below sea level, suggests that it may have emerged sometime in the past 30 million years. It is covered by a thick layer of limestone, pyroclastic rocks and bioclastic sandstones. Dredged basalts from the top of the eastern and southeastern flanks of the seamount have been K–Ar dated 10.7 ± 0.5 and 16.3 ± 0.4 million years old, respectively. The oldest sample has been 40Ar/39Ar dated at 17 ± 0.3 million years old. Two small seamounts exist just southwest of Great Meteor and are encircled by the −3800 m bathymetric line. These a ...

North Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Meteor Expedition
The German Meteor expedition (German: ''Deutsche Atlantik Expedition'') was an oceanographic expedition that explored the South Atlantic ocean from the equatorial region to Antarctica in 1925–1927. Depth soundings, water temperature studies, water samples, studies of marine life and atmospheric observations were conducted.Stein Expedition The survey vessel left Wilhelmshaven on 16 April 1925 with the oceanographer Alfred Merz in charge of the expedition.Nieder and Schroeder The ship zigzagged between Africa and South America and took echo soundings of the South Atlantic between 20° North and 60° South. In January 1926 the Strait of Magellan was transited; in March the same year a seamount was found and named ''Meteor Bank'' (). In June 1926 Merz, who already had health problems before the start of the expedition, was hospitalised at the German Hospital in Buenos Aires. He died of pneumonia on 25 August 1926. The overall lead of the expedition was assumed by the ship's c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
