Cormorant
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland, and the names "cormorant" and "shag" have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engines
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a diesel engine produces is controlled by manipulating the air-fue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built In Argentina
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, 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 ship-rigged sailing ship with three or more masts, each of which is 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%). Nomenclature Ships are typically larger than boats, but there is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Vessels Of Argentina
Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Auxiliary Ships Of The Argentine Navy
This list includes all major auxiliary ships (transports, colliers, tankers, scientific vessels, tugs, among others) in service with the Argentine Navy since being formally established in the 1860s.In 1861 the modern Argentine Republic was born, after the Battle of Pavón. It does not include vessels prior to that date, nor does it include warships which are listed separately. The list is organized by type of ship, by class within each type, and by service entry date within each class. Service entry dates indicate the ship's commissioning into the Argentine Navy, and not the ship's entry in service with another navy unless specifically said. There is a separate list of current ships of the Argentine Navy regardless the type. Naming tradition The current norms establish naming conventions for Argentine Navy ships according to their type; some of these used for auxiliaries are summarized below. ;Avisos, salvage ships, maritime tugs: Mariners or civilians of relevance to the ...

Paraná Delta
The Paraná Delta () is the delta of the Paraná River in Argentina and it consists of several islands known as the Islas del Paraná. The Paraná flows north–south and becomes an alluvial basin (a flood plain) between the Argentine provinces of Entre Ríos, Santa Fe and Buenos Aires then emptying into the . It covers about and starts to form between the cities of Santa Fe and Rosario, where the river splits into several arms, creating a network of islands and wetlands. Most of it is in the jurisdiction of Entre Ríos Province, and parts in the north of Buenos Aires Province. The Paraná Delta is conventionally divided into three parts: * the Upper Delta, from the Diamante – Puerto Gaboto line to Villa Constitución; * the Middle Delta, from Villa Constitución to the Ibicuy Islands; * the Lower Delta, from the Ibicuy Islands to the mouth of the river. The total length of the delta is about , and its width varies between . It carries 160 million tonnes of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río De La Plata
The Río de la Plata (; ), also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paraná River at Punta Gorda, Colonia, Punta Gorda. It empties into the Atlantic Ocean and forms a funnel-shaped indentation on the southeastern coastline of South America. Depending on the geographer, the Río de la Plata may be considered a river, an estuary, a gulf, or a marginal sea. If considered a river, it is the widest in the world, with a maximum width of . The river is about long and widens from about at its source to about at its mouth. It forms part of Argentina–Uruguay border, the border between Argentina and Uruguay.

Depth Sounding
Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms and feet. The National Oceanic and Atmospheric Administration (NOAA), the agency responsible for bathymetric data in the United States, still uses fathoms and feet on nautical charts. In other countries, the International System of Units (metres) has become the standard for measuring depth. Terminology "Sounding" derives from the Old English ''sund'', meaning "swimming, water, sea"; it is not related to the word ''sound'' in the sense of noise or tones, but to ''sound'', a geographical term. Traditional terms for soundings are a source for common expressions in the English language, notably "deep six" (a sounding of 6 fathoms). On the Mississippi River in the 1850s, the leadsmen also used old-fashi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentine Naval Hydrographic Service
The Argentine Hydrographic Service (, abbreviated SHN) is the branch of the Ministry of Defense responsible for providing hydrographic services. Background Created on January 1, 1879, as ''Oficina Central de Hidrografía'' () by decree 11.289 of President Nicolás Avellaneda. It became the current SHN on 1972 by National Law 19.922. Since 2007, it became part of the Ministry of Defense. The main mission of the SHN is to provide safe navigation on national waters. The service does so with the creation and maintenance of nautical charts, coastal marker buoys, and lighthouses. In concordance with the International Maritime Organization regulations, the SHN is also the global coordinator for the NAVAREA VI zone, which covers the South West Atlantic Ocean region and is responsible for issuing alerts to ships at sea and coordinating search and rescue operations. The national official time is also a responsibility of the SHN through the National Naval Observatory. By means of De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navigation Radar
Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart.Maloney, 2003:744. A fix consisting of only radar information is called a ''radar fix''.Bowditch, 2002:816. Some types of radar fixes include the relatively self-explanatory methods of "range and bearing to a single object,"National Imagery and Mapping Agency, 2001:163. "two or more bearings," "tangent bearings," and "two or more ranges." Parallel indexing is a technique defined by William Burger in the 1957 book ''The Radar Observer's Handbook''.National Imagery and Mapping Agency, 2001:169. This technique involves creating a line on the screen that is parallel to the ship's course, but offset to the left or right by some distance. This ...
