The price of Brent Crude, one of the first types of oil extracted from the North Sea is used today as a standard price for comparison for crude oil from the rest of the world. [142] The North Sea contains western Europe's largest oil and natural gas reserves and is one of the world's key non-OPEC producing regions. [143]
The seabed is separated into three bathymetric areas, the Norwegian Trench and the north and south North Sea separated by the Dogger Bank. [3] For the most part, the sea lies on the European continental shelf. The only exception is the Norwegian trench, which reaches from the Stad peninsula in Sogn og Fjordane to the Oslofjord.
Location of the Mariana Trench. The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.
The Mariana Trench is the deepest known submarine trench, and the deepest location in the Earth's crust itself. [38] It is a subduction zone where the Pacific Plate is being subducted under the Mariana Plate. [3] At the deepest point, the trench is nearly 11,000 m deep (almost 36,000 feet).
There are about 50,000 km (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench , at a depth of 10,994 m (36,070 ft) below sea level .
During interglacial periods (when sea levels were high) between the initial flooding 450,000 years ago until around 180,000 years ago, the Channel would still have been separated from the North Sea by a land bridge to the north of the Strait of Dover (the Strait of Dover at this time formed part of a estuary fed by the Thames and Scheldt ...
Kelly Walsh dived 11,000m under the ocean to Challenger Deep, 60 years after his father Don Walsh made the journey. He tells Bevan Hurley he’s watched the Titan rescue in ‘horror and sadness’
Map of oil and gas fields. This list of oil and gas fields of the North Sea contains links to oil and natural gas reservoirs beneath the North Sea.In terms of the oil industry, "North Sea oil" often refers to a larger geographical set, including areas such as the Norwegian Sea and the UK "Atlantic Margin" (west of Shetland) which are not, strictly speaking, part of the North Sea.
