Early Middle Ages
The Early Middle Ages (or early medieval period), sometimes controversially referred to as the Dark Ages, is typically regarded by historians as lasting from the late 5th or early 6th century to the 10th century. They marked the start of the Middle Ages of European history, following the decline of the Western Roman Empire, and preceding the High Middle Ages ( 11th to 13th centuries). The alternative term ''late antiquity'', for the early part of the period, emphasizes elements of continuity with the Roman Empire, while ''Early Middle Ages'' is used to emphasize developments characteristic of the earlier medieval period. The period saw a continuation of trends evident since late classical antiquity, including population decline, especially in urban centres, a decline of trade, a small rise in average temperatures in the North Atlantic region and increased migration. In the 19th century the Early Middle Ages were often labelled the ''Dark Ages'', a characterization based on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Black Sea Shipwrecks
Ancient Black Sea shipwrecks found in the Black Sea date to Ancient history, Antiquity. In 1976, Willard Bascom suggested that the deep, anoxic waters of the Black Sea might have preserved shipwreck, ships from antiquity because typical wood-devouring organisms could not survive there. At a depth of 150m, the Black Sea contains insufficient oxygen to support most familiar biological life forms. Meromictic composition and preservation Originally a land-locked fresh water lake, the Black Sea was flooded with salt water from the Mediterranean Sea during the Holocene. The influx of salt water essentially smothered the fresh water below it because a lack of internal motion and mixing meant that no fresh oxygen reached the deep waters, creating a meromictic lake, meromictic body of water. The anoxic environment, which is hostile to many biological organisms that destroy wood in the oxygenated waters, provides an excellent testing site for deep water archaeological survey.

Meromictic
A meromictic lake is a lake which has layers of water that do not intermix. In ordinary, holomictic lakes, at least once each year, there is a physical mixing of the surface and the deep waters. The term ''meromictic'' was coined by the Austrian Ingo Findenegg in 1935, apparently based on the older word ''holomictic''. The concepts and terminology used in describing meromictic lakes were essentially complete following some additions by G. Evelyn Hutchinson in 1937. Characteristics Most lakes are ''holomictic''; that is, at least once per year, physical mixing occurs between the surface and the deep waters. In so-called monomictic lakes, the mixing occurs once per year; in dimictic lakes, the mixing occurs twice a year (typically spring and autumn), and in polymictic lakes, the mixing occurs several times a year. In meromictic lakes, however, the layers of the lake water can remain unmixed for years, decades, or centuries. Meromictic lakes can usually be divided into th ...

Crimean Peninsula
Crimea, crh, Къырым, Qırım, grc, Κιμμερία / Ταυρική, translit=Kimmería / Taurikḗ ( ) is a peninsula in Ukraine, on the northern coast of the Black Sea, that has been occupied by Russia since 2014. It has a population of 2.4 million. The peninsula is almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Sivash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. Crimea (called the Tauric Peninsula until the early modern period) has historically been at the boundary between the classical world and the steppe. Greeks colonized its southern fringe and were absorbed by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byzantine
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

Sinop D
Sinop D is an ancient Black Sea shipwreck located to the east of Sinop, Turkey. The ship was discovered by a team led by Robert Ballard with Dan Davis in 2000. The team discovered the well-preserved wreck at a 320 m depth, in the Black Sea's deep anoxic waters. The vessel's entire hull and cargo are intact, buried in sediments. Its deck structures are also intact, including a mast, and rope attached on the top, rising some 11 m into the water column. Radiocarbon dating of wood from the wreck provides a date of 410–520 CE. However, the wreck could not be completely salvaged as the mud and sediment encasing the wreck were hard to remove without possibly causing damage to the already fragile ship. Excavations In 2000, Ballard and his team conducted an expedition that focused on the exploration of the sea bed about 15–30 km west of Sinop, and an additional deep-water survey east and north of the peninsula. Their project had several goals. They sought to discover whether huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Ballard
Robert Duane Ballard (born June 30, 1942) is an American retired Navy officer and a professor of oceanography at the University of Rhode Island who is most noted for his work in underwater archaeology: maritime archaeology and archaeology of shipwrecks. He is best known for the discoveries of the wrecks of the RMS ''Titanic'' in 1985, the battleship ''Bismarck'' in 1989, and the aircraft carrier in 1998. He discovered the wreck of John F. Kennedy's ''PT-109'' in 2002 and visited Biuku Gasa and Eroni Kumana, who saved its crew. Despite his long successes in shipwrecks, Ballard considers his most important discovery to be that of hydrothermal vents. Ballard has also established the JASON Project and leads ocean exploration on the research vessel E/V ''Nautilus''. . Downloahere Early life Robert Ballard grew up in Pacific Beach, San Diego, California to a mother of German heritage and a father of British heritage. He has attributed his early interest in underwater expl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Archaeology
Maritime archaeology (also known as marine archaeology) is a discipline within archaeology as a whole that specifically studies human interaction with the sea, lakes and rivers through the study of associated physical remains, be they vessels, shore-side facilities, port-related structures, cargoes, human remains and submerged landscapes. A specialty within maritime archaeology is nautical archaeology, which studies ship construction and use. As with archaeology as a whole, maritime archaeology can be practised within the historical, industrial, or prehistoric periods. An associated discipline, and again one that lies within archaeology itself, is underwater archaeology, which studies the past through any submerged remains be they of maritime interest or not. An example from the prehistoric era would be the remains of submerged settlements or deposits now lying under water despite having been dry land when sea levels were lower. The study of submerged aircraft lost in lakes, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
