Research cruises
Every summer, scientists from the Centre for Deep Sea Research travel to the Norwegian-Greenland Sea to map the volcanic seafloor of the mid-ocean ridge, search for new hydrothermal vent fields and sample hydrothermal fluids, chimneys, volcanic rocks, microbial mats and larger organisms. Our work onboard forms the basis of new scientific discoveries that gradually reveal the unknown world on the seafloor.
Kartlegging med Hugin
Main content
Deep-sea research is demanding. To reach our scientific goals, we are dependent on overcoming the practical and technological challenges of diving to depths of more than 2000 metres below the sea surface. Only at these depths can we get a glimpse of the natural treasures of Earth's last frontier.
A range of advanced and customized equipment is available on board the research vessels聽 补苍诲听.聽The autonomous underwater vehicle聽system Hugin provides high resolution maps of the seafloor. The system has sensors that detect chemical compounds, such as methane and CO2, in the water column. These sensors are essential in the search for new hydrothermal vent fields.聽The unmanned, remotely operated underwater vehicle (ROV) named 脝gir 6000 is one of few vessels in the world that can dive to depths of 6000 metres! In the darkness of the deep sea, 脝gir collects samples, deploys and picks up experiments, and videos whatever it encounters, giving the scientists at the surface聽new insights into this unique,聽deep-marine environment.
Back at the Centre for Deep Sea Research in Bergen, the results from the efforts at sea start to emerge. Maybe our sediment samples contain undescribed organisms that聽? The data collected during our expeditions form聽the foundation of most of the activities at the centre. It is therefore safe to say that the cruises make up the backbone of our research.聽
The Centre is in possession of many hours of exciting video footage from the deep sea. Please contact us if you wish to use any of the footage. The following links show a selection of our videos and media contributions:
- Videos from live streaming of the underwater vehicle 脝gir 6000s exploration of the deep sea are available聽on our web site.
