Strýtan Vent Field
The Strýtan vent field is a hydrothermal vent field located in the northern Atlantic Ocean at a depth of . It is located within Iceland's northern fjord Eyjafördur near Akureyri. As of 2024, it is the only known alkaline hydrothermal vent field hosted on basalt rock. It is a popular site for divers. History The oldest reports of the Strýtan vent field date back hundreds of years to fishermen using dive weights. However, the Icelandic Coast Guard did not detect the vent chimneys and declared them as non-existent in 1987. Only in 1997 was the Strýtan vent field reported by divers Erlendur Bogason and Árni Halldósson and identified as a real geologic feature. It was also explored by GEOMAR in 1997, using the HOV ''JAGO'', a German research submersible. In 2001, Strýtan was designated as a protected Icelandic preserve. Geology and location Strýtan is in the vicinity of the Dalvík Lineament, which connects to the Eyjafjarðaráll Rift which extends to the Kolbeinsey ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Lost City Hydrothermal Field
The Lost City Hydrothermal Field, often referred to simply as Lost City, is an area of marine alkaline hydrothermal vents located on the Atlantis Massif at the intersection between the Mid-Atlantic Ridge and the Atlantis Transform Fault, in the Atlantic Ocean. It is a long-lived site of active and inactive ultramafic-hosted serpentinization, abiotically producing many simple molecules such as methane and hydrogen which are fundamental to microbial life. As such it has generated scientific interest as a prime location for investigating the origin of life on Earth and other planets similar to it. Expedition history The Lost City was first identified on December 4, 2000, using DSV ''Alvin'' and ROV ''ArgoII'' on cruise AT03-60 of the RV ''Atlantis''. The cruise lasted 34 days, during which photographs and vent chimney samples were taken. The discovery of the Lost City prompted the National Science Foundation to fund a second, 32-day voyage (AT07-34) to the site in 2003 in order ...
