Skagerrak
The Skagerrak (Danish: [ˈskɛːjɐˌʁɑk], Norwegian: [ˈskɑ̀ːɡərɑk], Swedish: [ˈskɑ̌ːɡɛrak]) is a strait running between the Jutland peninsula of Denmark, the east coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea.

The Skagerrak contains some of the busiest shipping routes in the world, with vessels from every corner of the globe. It also supports an intensive fishing industry.[1] The ecosystem is strained and negatively affected by direct human activities. Oslo and Gothenburg are the only large cities in the Skagerrak region.
The strait is likely named after Skagen, a town near the northern cape of Denmark, with 'Rak' meaning 'straight waterway'. The Skagerrak is 240 km long and 80–140 km wide, deepening towards the Norwegian coast. It has an average salinity comparable to other coastal waters, housing a variety of habitats.
Historically, the Skagerrak was the only access to the Baltic Sea until the construction of the Eider Canal in 1784. During both World Wars, the strait held strategic importance for Germany. Presently, it remains one of the busiest straits worldwide.
The Skagerrak serves as a habitat for approximately 2,000 marine species, including a unique variety of Atlantic cod. It also contains sandy and stony reefs and cold-water coral reefs. Environmental institutions have expressed concern about increasing pressure on the ecosystem due to human activities and climate change. Protections are in place, with several marine protected areas in Skagerrak, including Ytre Hvaler National Park in Norway and Kosterhavet National Park in Sweden.
Name[edit]
The meaning of Skagerrak is most likely the Skagen Channel/Strait. Skagen is a town near the northern cape of Denmark (The Skaw). In Dutch, rak means 'straight waterway', as seen in Dutch hydronyms such as Damrak, Gouderak, Langerak, Tuikwerderrak, and Volkerak), cognate with reach.[2][3] The ultimate source of this syllable is the Proto-Indo-European root *reg-, 'straight'. Rak means 'straight' as in 'straight ahead' in modern Norwegian and Swedish. Råk in both modern Norwegian and Swedish refers to a channel or opening of water in an otherwise ice-covered body of water. There is no evidence to suggest a connection with the modern Danish word rak (meaning rabble or riff-raff). It is therefore likely that the Skagerrak was named by Dutch seafarers, as was the adjacent Kattegat.
Recreation[edit]
Skagerrak is popular for recreational activities in all three countries. There are many summer house residences and several marinas along the coasts.
Environmental concerns[edit]
Scientists and environmental institutions have expressed concern about the increasing pressure on the ecosystem in Skagerrak. The pressure has already had negative impacts and is caused by cumulative environmental effects, of which direct human activities are only one piece of the puzzle. Climate change and ocean acidification are expected to have increasing impacts on the Skagerrak ecosystem in the future.[1]
Skagerrak and the North Sea receives considerable inputs of hazardous material and radioactive substances. Most is ascribed to long-range transport from other countries, but not all.[12] Marine litter is also a growing problem. Until recently, waste water and sewage pouring into Skagerrak from settlements and industries was not treated at all. In combination with wash out of excessive nutrients from conventional farming, this has often led to large algae blooms.[13]
There are several marine protections in Skagerrak, including:
In popular culture[edit]
Skaagerak is the setting of the popular television show Badehotellet from Denmark.
