Deep-sea hydrothermal systems and geodynamics
Seafloor spreading takes place at different rates that scientists define as being “ultra-fast” (15 cm/year) to “ultra-slow” (<1.5 cm/year). The Arctic Mid-Ocean Ridge is one of the few places along the global ridge systems where spreading occurs at an ultra-slow rate.
The Arctic Mid-Ocean Ridge (AMOR) includes the ridges in the Norwegian-Greenland Sea and the Arctic Ocean.

About deep seafloor dynamics
At slow and ultra slow spreading rates the volcanic activity decreases. As a result, the oceanic crust becomes unusually thin, and in some areas no crust may be present with the mantle being exposed at the seafloor.

Future directions (from 2011)
In the future, the research under this theme will continue to focus on the Arctic Mid-Ocean Ridge (AMOR) system. In addition, we will also be involved in research in other areas of the global ridge system through our international network.

Research summary 2007-2010
Research in this theme involves deep-sea exploration and searching for new extreme environments. It therefore forms a basis for the geobiological research carried out by several of the other themes.

Sedimentary deposits represent Earth’s history book. By diggingdeeper and deeper into sedimentary layers, archeologists can read the history of mankind, and by sampling older sedimentary rocks paleontologists study the prehistoric life on Earth.
