China – January 28th, 2013

Haze hangs over northeastern China, particularly over the plains by the Yangtze River Delta. The delta comprises the triangular-shaped territory of Wu-speaking Shanghai, southern Jiangsu province and northern Zhejiang province of China, by where the Yangtze River drains into the East China Sea.

The urban build-up in the area has given rise what may be the largest concentration of adjacent metropolitan areas in the world. It covers an area of 99600 km2 and is home to over 105 million people as of 2010, of which an estimated 80 million is urban.

Visible to the east, offshore, is the island and Korean province of Jeju, south of the Korean Peninsula (upper right quadrant). Streaming off the island to the south are Van Kármán vortex streets, a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around blunt bodies (in this case, the island of Jeju).

Sediments Along Chinese Coast from Bohai Sea to Yangtze Delta

A great deal of tan sediments spill from the Huangpu River, a tributary of the Yangtze, into the East China Sea near Shanghai on the Yangtze River Delta.

Sediments are also present, though in a lesser quantity, along the shores of the Shandong Peninsula (above center) and the Bohai Sea.

Inland, near the delta, Lake Tai appears greenish tan. Lake Tai, literally “Grand Lake”, is on the Yangtze Delta Plain, on the border of the Jiangsu and Zhejiang provinces.

Shanghai, China - April 23rd, 2009

The city of Shanghai, here visible as a large grey area, sits on the Yangtze River Delta on China’s eastern coast, and is roughly equidistant from Beijing and Hong Kong.

The municipality as a whole consists of a peninsula between the Yangtze and Hangzhou Bay, China’s third largest island Chongming, and a number of smaller islands.

The city proper is bisected by the Huangpu River, a tributary of the Yangtze. Huangpu means “Yellow Bank River”, and true to its name, here it can be seen spilling golden brown sediments into the East China Sea.

The historic center of Shanghai, the Puxi area, is located on the western side of the Huangpu, while a new financial district, Pudong, has developed on the eastern bank.

The city has many rivers, canals, streams and lakes and is known for its rich water resources as part of the Taihu drainage area.

In the full image, the Korean Peninsula is also visible to the north. Sediments can be seen flowing from its rivers as well, particularly near the southern tip.

Dense brown sediments spill from the Yangtze River Delta into the East China Sea, clouding he coastal waters up to the Shandong Peninsula. Above the peninsula, also known as the Jiāodōng Peninsula, the Bóhăi Sea also has sediments along its shoreline, although they appear more reddish than those from the delta.

The delta is one of the most densely populated regions on earth, and includes one of the world’s largest cities on its banks—Shanghai, with a density of 2,700 inhabitants/km². Because of the large population of the delta, and factories, farms, and other cities upriver, the World Wide Fund for Nature says the Yangtze Delta is the biggest cause of marine pollution in the Pacific Ocean.

To the northeast, the Korean Peninsula is visible, with yellow sediments along the South Korean shoreline and darker brown sediments near the border between North and South Korea.
