High tide in the context of "Southern Dispersal"

A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection.

Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent acknowledgment by both environmentalists and larger society for the importance of saltwater marshes for biodiversity, ecological productivity and other ecosystem services, such as carbon sequestration, have led to an increase in salt marsh restoration and management since the 1980s.

Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.

Larger tidal range occur during spring tides (spring range), when the gravitational forces of both the Moon and Sun are aligned (at syzygy), reinforcing each other in the same direction (new moon) or in opposite directions (full moon). The largest annual tidal range can be expected around the time of the equinox if it coincides with a spring tide. Spring tides occur at the second and fourth (last) quarters of the lunar phases.

USS Missouri (hull number BB-63) is an Iowa-class battleship built for the United States Navy (USN) in the 1940s and is now a museum ship. Completed in 1944, she is the last battleship commissioned by the United States. The ship was assigned to the Pacific Theater during World War II, where she participated in the Battles of Iwo Jima and Okinawa and shelled the Japanese home islands. Her quarterdeck was the site where the Japanese Instrument of Surrender was signed, officially ending World War II.

After World War II, Missouri served in various diplomatic, show of force and training missions. In 1950, the ship ran aground during high tide in Chesapeake Bay and after great effort was re-floated several weeks later. She later fought in the Korean War during two tours between 1950 and 1953. Missouri was the first American battleship to arrive in Korean waters and served as the flagship for several admirals. The battleship took part in numerous shore bombardment operations and also served in a screening role for aircraft carriers. Missouri was decommissioned in 1955 and transferred to the reserve fleet (also known as the "Mothball Fleet").

A terp, also known as a wierde, woerd, warf, warft, werf, werve, wurt or værft, is an artificial dwelling mound found on the North European Plain that has been created to provide safe ground during storm surges, high tides and sea or river flooding. The various terms used reflect the regional dialects of the North European region.

Terps are found in the coastal regions of the Netherlands, particularly in the provinces of Zeeland, Friesland and Groningen, as well as in southern Denmark and northwestern Germany. Before the construction of dykes, these mounds provided protection against floodwaters that regularly disrupted daily life. They are especially common in East Frisia (Ostfriesland) and Nordfriesland in Germany. On the Halligen islands in Kries Norfriesland, people continue to live on terps without the protection of dykes. Terps are also present in the Rhine and Meuse river plains in central Netherlands. Further examples occur in North Holland, such as Avendorp near Schagen, and in the towns of Bredene and Leffinge near Oostende in Belgium. Additional terps are located at mouth of the IJssel River, including at Kampereiland in the province of Overijssel, as well as on the former island of Schokland in the Zuiderzee, now part of the reclaimed Noordoostpolder. An old terp, known as Het Torp is also located beneath the town of Den Helder in North Holland.

Yangshan Port (Chinese: 洋山港, p Yángshān Gǎng, Wu Yan-se Kaon), formally the Yangshan Deep-Water Port (洋山深水港, p Yángshān Shēnshuǐ Gǎng, Wu Yan-se Sen-sy Kaon), is an offshore deep-water port for containerization in Hangzhou Bay south of Shanghai, China, built on land reclamation joining the Lesser Yangshan Island with numerous other nearby islands of the northwestern Zhoushan archipelago. It is connected to Shanghai's Pudong New Area on the mainland by the 32.5 km-long (20.2 mi) Donghai Bridge, forming part of the Port of Shanghai, while the other islands of Yangshan archipelago (including the Greater Yangshan Island, where the civilian population of the archipelago live) are administered separately as part of Zhejiang's Shengsi County.

Yangshan Port is part of China's Maritime Silk Road, built to allow the Port of Shanghai to grow despite shallow waters near the shore. Prior to its construction, the Port of Shanghai was predominantly based around the mouth of the Huangpu River, which is too shallow to handle large container ships, forcing the port to often perform mid-stream operations within the Yangtze estuary, which often had to wait for the high tide hours, severely restricting the port's capacity. The construction of Yangshan Port allows berths with depths of up to 15 m (49 ft) to be built, and can handle today's largest container ships. In mid-2011, port officials said the port was on track to move 12.3 million twenty-foot equivalent units (TEUs) during the year, up from 10.1 million TEUs in 2010, overtaking Port of Singapore to become the world's busiest container port. In 2015, the port handled 36.54 million TEUs, and by 2019, its throughput had increased to 43.35 million TEU.

Cotidal lines are the set of places where high tide occurs at the same time.

They sometimes all meet at a particular point called the amphidromic point, where the amplitude of the tide is almost null.
