Littoral zone in the context of "Navy"

The salinity of water bodies varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, among other elements, some in minute concentrations. A wide variety of organisms, including bacteria, protists, algae, plants, fungi, and animals live in various marine habitats and ecosystems throughout the seas. These range vertically from the sunlit surface and shoreline to the great depths and pressures of the cold, dark abyssal zone, and in latitude from the cold waters under polar ice caps to the warm waters of coral reefs in tropical regions. Many of the major groups of organisms evolved in the sea and life may have started there.

The United States Navy (USN) is the maritime service branch of the United States Armed Forces and the naval warfare force of the United States. It is the world's most powerful navy with the largest displacement, at 4.5 million tons in 2021. It has the world's largest aircraft carrier fleet, with eleven in service, one undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of 18 July 2023. The U.S. Navy is a part of the United States Department of Defense and is one of six armed forces of the United States and one of eight uniformed services of the United States.

The United States Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. After suffering significant loss of goods and personnel at the hands of the Barbary pirates from Algiers, the United States Congress passed the Naval Act of 1794 for the construction of six heavy frigates, the first ships of the Navy. The United States Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Imperial Japan. The United States Navy emerged from World War II as the most powerful navy in the world, succeeding the British Navy. The modern United States Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean, and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it a frequent actor in American foreign and military policy.

The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces. It is one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest coast guard in the world.

The U.S. Coast Guard protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across U.S. territorial waters and its Exclusive Economic Zone. Due to ever-expanding risk imposed by transnational threats through the maritime and cyber domains, the U.S. Coast Guard is at any given time deployed to and operating on all seven continents and in cyberspace to enforce its mission. Like its United States Navy sibling, the U.S. Coast Guard maintains a global presence with permanently-assigned personnel throughout the world and forces routinely deploying to both littoral and blue-water regions. The U.S. Coast Guard's adaptive, multi-mission "white hull" fleet is leveraged as a force of both diplomatic soft power and humanitarian and security assistance over the more overtly confrontational nature of "gray hulled" warships. As a humanitarian service, it saves tens of thousands of lives a year at sea and in U.S. waters, and provides emergency response and disaster management for a wide range of human-made and natural catastrophic incidents in the U.S. and throughout the world.

The Slovene Littoral, or simply Littoral (Slovene: Primorska, pronounced [pɾiˈmóːɾska] ; Italian: Litorale; German: Küstenland), is one of the traditional regions of Slovenia. The littoral in its name – for a coastal-adjacent area – recalls the former Austrian Littoral (Avstrijsko Primorje), the Habsburg possessions on the upper Adriatic coast, of which the Slovene Littoral was part. Today, the Littoral is often associated with the Slovenian ethnic territory that, in the first half of the 20th century, found itself in Italy to the west of the Rapallo Border, which separated a quarter of Slovenes from the rest of the nation, and was strongly influenced by Italian fascism.

Narta Lagoon (Albanian: Laguna e Nartës) is a lagoon of the Adriatic Sea on the Mediterranean Sea in the central coast of Albania. The lagoon extends north of the Bay of Vlorë on the eastern shore of the Strait of Otranto and is separated from the sea by a narrow littoral strip, consisting of an alluvial dune. It has a surface area of 41.8 km (16.1 sq mi) with a maximal depth of 1.5 m (4.9 ft).

It is situated within the boundaries of the Vjosa Wild River National Park, and has been recognised as an important Bird and Plant Area of international importance. As of May 2020, it is home to 3,000 flamingos. It is formed by the constant accumulation of solid flow of the Vjosa River, which originates within the Pindus Mountains close to the border between Albania and Greece.

Croatian Littoral (Croatian: Hrvatsko primorje) is a historical name for the region of Croatia comprising mostly the coastal areas between traditional Dalmatia to the south, Mountainous Croatia to the north, Istria and the Kvarner Gulf of the Adriatic Sea to the west. The term "Croatian Littoral" developed in the 18th and 19th centuries, reflecting the complex development of Croatia in historical and geographical terms.

The region saw frequent changes to its ruling powers since classical antiquity, including the Roman Empire, the Ostrogoths, the Lombards, the Byzantine Empire, the Frankish Empire, and the Croats, some of whose major historical heritage originates from the area—most notably the Baška tablet. The region and adjacent territories became a point of contention between major European powers, including the Republic of Venice, the Kingdom of Hungary, and the Habsburg and Ottoman Empires, as well as Austria, the First French Empire, the Kingdom of Italy, and Yugoslavia.

The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life, such as sea stars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the littoral zone or seashore, although those can be defined as a wider region.

The intertidal zone also includes steep rocky cliffs, sandy beaches, bogs or wetlands (e.g., vast mudflats). This area can be a narrow strip, such as in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in the intertidal zone are well-adapted to their environment, facing high levels of interspecific competition and the rapidly changing conditions that come with the tides. The intertidal zone is also home to several species from many different phyla (Porifera, Annelida, Coelenterata, Mollusca, Arthropoda, etc.).
