Bohai Bay

Bohai Bay (simplified Chinese: 渤海湾; traditional Chinese: 渤海灣; pinyin: Bóhǎi Wān) is one of the three bays forming the Bohai Gulf, the innermost gulf of the Yellow Sea, in northeast China. It borders Hebei province and Tianjin Municipality. The three bays are Laizhou Bay to the south, Liaodong Bay to the north, and Bohai Bay to the west.

It is the most southerly sea in the northern hemisphere in which sea ice can form.[1]

The Bohai Bay is the drainage of the Haihe and 15 other rivers.[2] Due to these rivers' muddy runoff, the bay used to be a highly silty water body, but extensive damming of the various river systems has greatly diminish siltage. Nevertheless, the Bohai Bay in effect concentrates the runoff of the whole eastern North China Plain, and the Bay is an intensely polluted body of water.[3]

Fisheries were traditionally some of the richest in China, fed by enormous sediment runoff and extensive shallows to serve as hatcheries. Pollution, eutrophication, habitat destruction caused by land reclamation, and intense overfishing have resulted in a collapse of stocks, and a decline of trawl catch per unit of effort (CPUE) from 138.8 kg/ to 11.2 kg/ from 1959 to 1998.[4]

The Bohai Bay is ringed by several major ports: the Port of Tianjin, the large Port of Tangshan itself which consists of three ports (Caofedian, Jingtang and Fennan), and the Port of Huanghua, making the Bay into a very crowded waterway. Land reclamation in Tianjin and in Caofeidian have greatly changed the littoral zone, and destroyed much of the area's wetlands. Land reclamation has also affected migratory birds.[5]

As is the case of most of the Bohai Sea, the Bohai Bay is rich in hydrocarbon deposits and has several active offshore oil fields. Jidong Nanpu contains 7,500,000,000 barrels (1.19×109 m3), while the bay as a whole is estimated to contain 146 billion barrels (23.2×109 m3).[6]

On June 4, 2011, a large oil spill occurred related to the China National Offshore Oil Corporation.[7]

2011 Bohai Bay oil spill

The 2011 Bohai bay oil spill (Chinese: 2011年渤海湾油田溢油事故) was a series of oil spills that began on June 4, 2011 at Bohai Bay. The spill itself however was not publicly disclosed until a month later. There were suspicions of official cover-ups by the State Oceanic Administration (SOA).

Bohai Economic Rim

The Bohai Economic Rim (BER) or Bohai Bay Economic Rim is the economic region surrounding Beijing and Tianjin. It also includes areas in Hebei, Liaoning and Shandong surrounding the Bohai Sea. This region has undergone major economic and infrastructural changes and is an emerging economic powerhouse of Northern China, rivalling the Pearl River Delta in the south and the Yangtze River Delta in the east.

Bohai Sea

The Bohai Sea or Bo Sea, also known as Bohai Gulf, Bo Gulf or Pohai Bay (Chinese: 渤海; literally: 'Bo Sea'), is the innermost gulf of the Yellow Sea and the Korea Bay on the coast of Northeastern and North China. It is approximately 78,000 km2 (30,000 sq mi) in area. Its proximity to Beijing makes it one of the busiest seaways in the world.


Caofeidian (Chinese: 曹妃甸; pinyin: Cáofēidiàn) is a land reclamation-converted economic development zone in Bohai Bay located in the eponymous district of Tangshan, Hebei Province, China.It hosts a large coal and ore discharging port, which forms one of the prime ports of Northern China, namely (from South to North) Tianjin - Jing Tang - Caofedian - Qinhuangdao - YingKou - Bayuquan - Dalian). Caofedian and Jingtang ports are often referred together as Tangshan port, though Tangshan is actually a large inland city away from the shore.

China National Offshore Oil Corporation

China National Offshore Oil Corporation, or CNOOC Group (Chinese: 中国海洋石油总公司 Pinyin: Zhōngguó Háiyáng Shíyóu Zǒnggōngsī), is one of the largest national oil companies in China. It is the third-largest national oil company in the People's Republic of China, after CNPC (parent of PetroChina) and China Petrochemical Corporation (parent of Sinopec). The CNOOC Group focuses on the exploitation, exploration and development of crude oil and natural gas in offshore China, alongwith its subsidiary COOEC.

The company is owned by the government of the People's Republic of China, and the State-Owned Assets Supervision and Administration Commission of the State Council (SASAC) assumes shareholder rights and obligations on the government's behalf. One subsidiary, CNOOC Limited, is listed on the Hong Kong exchange; the other, China Oilfield Services, is listed on the Hong Kong and New York exchanges.

Deposition (geology)

Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of gravity and friction, creating a resistance to motion; this is known as the null-point hypothesis. Deposition can also refer to the buildup of sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which has induced chemical processes (diagenesis) to deposit further calcium carbonate. Similarly, the formation of coal begins with deposition of organic material, mainly from plants, in anaerobic conditions.


Hebei (河北; formerly romanised as Hopeh) is a province of China in the North China region. The modern province was established in 1911 as Zhili Province or Chihli Province. Its one-character abbreviation is "冀" (Jì), named after Ji Province, a Han dynasty province (zhou) that included what is now southern Hebei. The name Hebei literally means "north of the river", referring to its location entirely to the north of the Yellow River.The modern province "Chili Province" was formed in 1911, when the central government dissolved the central governed area of "Chihli", which means "Directly Ruled (by the Imperial Court)" until it was renamed as "Hebei" in 1928.

Beijing and Tianjin Municipalities, which border each other, were carved out of Hebei. The province borders Liaoning to the northeast, Inner Mongolia to the north, Shanxi to the west, Henan to the south, and Shandong to the southeast. Bohai Bay of the Bohai Sea is to the east. A small part of Hebei, Sanhe Exclave, consisting of Sanhe, Dachang Hui Autonomous County, and Xianghe County, an exclave disjointed from the rest of the province, is wedged between the municipalities of Beijing and Tianjin.

A common alternate name for Hebei is Yānzhào (燕趙), after the state of Yan and state of Zhao that existed here during the Warring States period of early Chinese history.

Taizi River

The Taizi River (Chinese: 太子河) is a major river in the Liaoning province of Northeastern China. The river was historically also known as Yan River (衍水) or Liang River (梁水). It was originally the third largest tributary of the Liao River, southern Northeast's principal river, draining with the neighboring Hun River into a confluence known as "Trident River" near Haicheng, until a river engineering project in 1958 cut off the eastern distributary of the river delta from the Liao River's main course, making the Hun River and Taizi Rivers a separate system that drains into the Bohai Bay independently from the Liao River. However, both sister rivers are still usually considered a part of the Liao River system because they are both within the historical Liao River drainage basin.
