Oslofjord

The Oslofjord (Norwegian: Oslofjorden, Urban East Norwegian: [ˈʊ̂ʂlʊˌfjuːɳ]; English: Oslo Fjord) is an inlet in southeastern Norway. The 120-kilometre (75 mi) fjord begins at the small village of Bonn in Frogn Municipality and stretches northwards to the city of Oslo, and then curves to the east and then south. It then flows south to an imaginary line running between the Torbjørnskjær Lighthouse and Færder Lighthouse where it becomes part of the Skagerrak strait. The Skagerrak connects the North Sea and the Kattegat sea area, which leads to the Baltic Sea. The Oslofjord is not a fjord in the geological sense, but in the Norwegian language, the term fjord can refer to a wide range of waterways including inlets such as this one. The bay is divided into the inner (indre) and outer (ytre) Oslofjord, separated by the 17 km (11 mi) long by 1 km (0.62 mi) wide Drøbak Sound. The innermost part is known as Bunnefjorden.
