Underwater Domain Awareness
Underwater domain awareness (UDA) is the aspect of maritime domain awareness focused on the underwater sector, including, from a security perspective, sea lines of communication (SLOC), coastal waters and varied maritime assets with reference to hostile intent and the proliferation of submarine and mine capabilities intended to limit access to the seas and littoral waters. The military requirement is not the only motivation for undersea domain awareness. The earth's undersea geophysical activities as they relate to the well-being of humans is also relevant, as monitoring such activities can provide vital clues to minimize the impact of devastating natural disasters. Undersea commercial activities need precise inputs on the availability of resources for exploitation providing the best possible results for economic gains. The regulators, on the other hand, need to know the pattern of exploitation to manage a sustainable plan. The many activities, commercial and military, have cr ...

SOSUS
The Sound Surveillance System (SOSUS) was a submarine detection system based on passive sonar developed by the United States Navy to track Soviet Navy, Soviet submarines. The system's true nature was classified with the name and acronym SOSUS themselves classified. The unclassified name ''Project Caesar'' was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. In 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems were coming on line, the name itself changed to Integrated Undersea Surveillance System (IUSS). The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance ...

Maritime Nation
A maritime nation is any nation that borders the sea and is dependent on its use for the majority of the following state activities: commerce and transport, war, to define a territorial boundary, or for any maritime activity (activities using the sea to convey or produce an end result).

Gulf Of Kyparissia
The Gulf of Kyparissia ( el, Κυπαρισσιακός Κόλπος, ''Kyparissiakos Kolpos'') is a long, curving indentation along the western coast of the Peloponnese peninsula, Greece. It lies between Cape Katakolo at the north end and Cape Konello (Akra Kounellos) to the south. Near the northern extreme is the city of Pyrgos, with the town of Zacharo near the center and the town of Kyparissia lying toward the southern end. Flowing into the gulf are the Alpheios and Neda rivers. Its southern part is also one of the main breeding grounds of the endangered loggerhead sea turtle. During the Middle Ages In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire ... and up to the 19th century, this body was known as the Gulf of Arcadia. References Gulfs of Greece Gulfs of the Mediterr ...

Cuvier's Beaked Whale
The Cuvier's beaked whale, goose-beaked whale, or ziphius (''Ziphius cavirostris'') is the most widely distributed of all beaked whales in the family Ziphiidae. It is smaller than most baleen whales yet large among beaked whales. Cuvier's beaked whale is pelagic, inhabiting waters deeper than . It has the deepest and longest recorded dives among whales at and 222 minutes respectively, though the frequency and reasons for these extraordinary dives are unclear. Despite its deep water habitat, it is one of the most frequently spotted beached whales. The species was named ''Ziphius cavirostris'' by Georges Cuvier, based on a skull fragment which he believed to be a fossil from an extinct species. He reused the genus name ''Ziphius'' from an undetermined species mentioned by historical sources. The species name ''cavirostris'' from Latin ' "hollow" and ' "beak", refers to a bony structure (cavity) anterior of the nares (the bones of the nose), now known as the prenarial basin. It ...

SURTASS
The AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), colloquially referred to as the ship's "Tail", is a towed array sonar system of the United States Navy. SURTASS Twin-Line consists of either the long passive SURTASS array or the Twin-line array consisting of two shorter passive arrays towed side by side. The Twin-line Engineering Development Model was installed on USNS ''Assertive'', and the first production model was installed on USNS ''Bold''. Both ships are no longer serving as SURTASS units. , SURTASS was deployed on the four ''Victorious''-class vessels and the (a small-waterplane-area twin hull (SWATH) vessel). History SURTASS began as development program in 1973 using the new research vessel ''Moana Wave''. In 1980 SURTASS passed OPEVAL. The new ''Stalwart''-class ocean surveillance ships had the first contract awarded on 26 September 1980 and were similar to the prototype ship, the ''Moana Wave''. Initially the SURTASS system were passive, receive only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Shock Test
A ship is a large watercraft that travels the world's oceans and other sufficiently deep 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. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. 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. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...
