About Strýtan - geothermal cone

Strýtan – geothermal cone
Strýtan is a diving spot in the North of Iceland. We go out from a small town called Hjalteyri which is just out of Akureyri, the capital of the North. Strytan is quite unique for the fact that it is the only underwater hydrothermal vent accessible to divers. These cones in Eyjafjörður rice from the 70 meters deep seafloor giving the divers great visibility to phenomena usually found in much deeper waters, inaccessible to divers. Strýtan was only discovered in 1997 but it has been in formation for over 11.000 years. When the hot water from the vent comes in contact with the cold ocean minerals precipitate and cones of magnesium and silicate are formed. So in a way Strýtan is still beeing formed since about 100 liters of water are gushing from it every second. The limestone chimney is the home of various species that only thrive in these special circumstances making this diving place extraordinary.
