In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...

In 2016 Shell paid US$80 million for the spill [ 1 ] Petroleum extraction in the Niger Delta has lead to many environmental issues. [ 2 ][ 3 ] The delta covers 20,000 km 2 (7,700 sq mi) within wetlands of ...
Nigeria's largest city, Lagos state is surrounded by water from the sea and a lagoon. the total estimated percentage of clean water supply in the city is about 81.32%. [33] However, since the raw water in the lagoon is too polluted, the city gets its water from the Ogun and Owo rivers. The city's oldest water treatment plant, located in Iju on ...
The Niger Delta mangrove is the third largest in the world and the largest in Africa. Since the 1960s oil and gas exploration has become an important economic activity, resulting in significant alteration of the landscape via pollution, urbanization and invasion.
The Niger Delta, as now defined officially by the Nigerian government, extends over 70,000 km 2 (27,000 sq mi) and makes up 7.5% of Nigeria's land mass. Historically and cartographically, it consists of present-day Bayelsa, Delta, and Rivers States. In 2000, however, Obasanjo's regime included Abia, Akwa-Ibom, Cross River State, Edo, Imo and ...
The sea-level curve (also known as the eustatic curve) is the representation of the changes of the sea level relative to present day mean sea level as gleaned from the stratigraphic record throughout the geological history. The first such curve is the Vail curve or Exxon curve. The names of the curve refer to the fact that in 1977 a team of ...
2010 ExxonMobil oil spill. On May 1, 2010, a ruptured ExxonMobil pipeline in the state of Akwa Ibom, Nigeria, spilled more than a million gallons into the delta and contributed to the major environmental issues in the Niger Delta. [1] The spill had occurred at an Exxon platform some 20–25 miles (32–40 km) offshore which feeds the Qua Iboe ...
The Niger delta basin is one of the largest subaerial basins in Africa. It has a subaerial area of about 75,000 km 2, a total area of 300,000 km 2, and a sediment fill of 500,000 km 3. [1] The sediment fill has a depth between 9–12 km. [2] It is composed of several different geologic formations that indicate how this basin could have formed ...
