INS Darshak
INS ''Darshak'' (J21) (Hindi: दर्शक lit.audience) is a hydrographic survey ship in the Indian Navy, under the Eastern Naval Command. Ship history Built by Goa Shipyard Limited and commissioned into the Naval service at Visakhapatnam under the command of Captain S.S. Karnik in 2001, ''Darshak'' is the Indian Navy's eighth hydrographic survey ship to have been indigenously designed and constructed. Incidentally, the first indigenously built survey ship of the Navy, inducted in 1964 and decommissioned in 1990, was also named INS ''Darshak''. The new ''Darshak'' is equipped with a range of surveying, navigational and communication systems. The next-generation surveying systems provided onboard include the multi-beam swath echo sounding system, differential global positioning system, motion sensors, sea gravimeter, magnetometer oceanographic sensors, side scan sonars and an automated data logging system.

Goa Shipyard Limited
Goa Shipyard Limited (GSL) is an Indian Government owned ship building company located on the West Coast of India at Vasco da Gama, Goa. It was established in 1957, originally by the colonial government of the Portuguese in India as the "Estaleiros Navais de Goa", to build barges to be used in Goa's growing mining industry, which took off after the establishment of India's blockade of Goa in 1955. In the wake of Portugal's defeat and unconditional surrender to India following the 1961 Indian annexation of Goa The Annexation of Goa was the process in which the Republic of India annexed ', the then Portuguese Indian territories of Goa, Daman and Diu, starting with the armed action carried out by the Indian Armed Forces in December 1961. In India ..., it was requisitioned to manufacture warships for the Indian Navy and the Indian Coast Guard. GSL is undergoing a modernisation of its yard to adapt to the latest technology in shipbuilding. To this purpose it is negotiating ...

Communication
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a Universality (philosophy), universal phenomenon and a Communication studies, specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing Semantics, meaning among Subject (philosophy), entities or Organization, groups through the use of sufficiently mutually understood signs, symbols, and Semiosis, semiotic conventions.

Archaeological
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tharangambadi
Tharangambadi (), formerly Tranquebar ( da, Trankebar, ), is a town in the Mayiladuthurai district of the Indian state of Tamil Nadu on the Coromandel Coast. It lies north of Karaikal, near the mouth of a distributary named Uppanar of the Kaveri River. Tranquebar was established on 19 November 1620 as the first Danish trading post in India. King Christian IV had sent his envoy Ove Gjedde who established contact with Raghunatha Nayak of Tanjore. An annual tribute was paid by the Danes to the Rajah of Tanjore until the colony of Tranquebar was sold to the British East India Company in 1845. Tharangambadi is the headquarters of Tharangambadi taluk. Its name means "place of the singing waves"; the old designation ''Trankebar'' remains current in modern Danish. Tharangambadi is located at the distance of 285 km from Chennai. The nearest airport is at Tiruchirapalli international airport at 172 km and the nearest port is at Karaikal at 26 km.

Nagapattinam
Nagapattinam (''nākappaṭṭinam'', previously spelt Nagapatnam or Negapatam) is a town in the Indian state of Tamil Nadu and the administrative headquarters of Nagapattinam District. The town came to prominence during the period of Medieval Cholas (9th–12th century CE) and served as their important port for commerce and east-bound naval expeditions. The Chudamani Vihara in Nagapattinam constructed by the Srivijayan king Sri Mara Vijayattungavarman of the Sailendra dynasty with the help of Rajaraja Chola I was an important Buddhist structure in those times. Nagapattinam was settled by the Portuguese and, later, the Dutch under whom it served as the capital of Dutch Coromandel from 1660 to 1781. In November 1781, the town was conquered by the British East India Company. It served as the capital of Tanjore district from 1799 to 1845 under Madras Presidency of the British. It continued to be a part of Thanjavur district in Independent India. In 1991, it was made the headquar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poompuhar
Puhar (also known as Poompuhar) is a town in the Mayiladuthurai district in the southern Indian state of Tamil Nadu. It was once a flourishing ancient port city known as Kaveri Poompattinam, which is described in Sangam literature like Silappadikaram, Manimekalai, Pattinapalai and Akananuru as the capital of the Early Chola kings in Tamilakam. Puhar is located near the mouth of the Kaveri river, on the sea coast. It is mentioned in the Periplus of the Erythraean Sea. It has now been established by marine archaeological research (conducted by the National institute of marine archaeology, Goa) that much of the town was washed away by progressive erosion and floods. In the 1960s and 1970s, archaeological research was conducted under the leadership of the noted archaeologist K. V. Soundararajan. Submerged wharves and several meter lengths of pier walls excavated in recent times have corroborated the literary references to Poompuhar. It was rebuilt several times after that. Ancient ...

Shipwreck
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. Angela Croome reported in January 1999 that there were approximately three million shipwrecks worldwide (an estimate rapidly endorsed by UNESCO and other organizations). When a ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships. Types Historic wrecks are attractive to maritime archaeologists because they preserve historical information: for example, studying the wreck of revealed information about seafaring, warfare, and life in the 16th century. Military wrecks, caused by a skirmish at sea, are studied to find details about the historic event; they reveal much about the battle that occurred. Discoveries of treasure ships, often from the period of European colonisation, which sank in remote locations leaving few livin ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.
