ROV Ægir 6000

The Geochemistry and Geobiology research group investigates the interactions between geological and biological processes on Earth. We study magmatic, hydrothermal, geochemical and biological processes in modern and ancient geological time, in environments ranging from deep marine sediments to high-temperature seafloor hot springs. 

Researchers from the Geochemistry and Geobiology group are part of the K.G. Jebsen Centre for Deep Sea Research
Our research focuses on six main topics and is tightly connected to the work packages of the K.G. Jebsen Centre. 

Ultra-slow spreading ridges
Arctic hydrothermal vents
Seafloor mineral resources
Hydrothermal experiments
Deep marine sediments
Earth system evolution

We have state-of-the-art facilities in analytical geochemistry and marine technology to our availability to support our research, including the research vessel G.O. Sars and the working class ROV Ægir 6000.

We are also responsible for BSc and MSc courses in mineralogy, geochemistry, geobiology, petrology and geomicrobiology

The GONORTH cruise was a success!

Early August, the GONORTH cruise organised by several Norwegian institutions came to an end. On its last ROV dive, a new hydrothermal vent field, named Ultima Thule, was discovered on the Lucky Ridge!

New publication in PNAS
The research team has instrumented nine high temperature vents with temperature loggers manufactured by EP Oceanographic. The loggers collect data every ten minutes, in order to track changes in vent fluid temperature that can be used to infer changes in

New Hydrothermal Field Discovered in East Pacific Ocean

The first-known, off-axis, high-temperature deep-sea hydrothermal vents along a portion of the northern East Pacific Rise are hotter and cover more area than any other hydrothermal vents studied to date along this section of the mid-ocean ridge. The discovery demonstrates that there are more...
