MAR-ECO Technology
The choice of appropriate tools (technologies), procedures and strategies can make the difference between the success and failure of a research expedition.

Rising to deep-sea challenges
About technology as one of the component projects within MAR-ECO.

Rising to deep-sea challenges

Research vessels: the G.O. Sars
"G.O. Sars" is one of the most advanced research vessels in the world and was handed over in May 2003. The vessel is used by the University of Bergen and the Institute of Marine Research.

Technology tests onboard G.O. Sars
Application of modern technology is considered one of the most critical factors for success in the challenging investigations MAR-ECO is aiming for. Substantial effort has therefore been invested in fitting RV G.O. Sars properly. In the end of April 2004 a test cruise was carried out onboard RV G.O. Sars

Longlining
During the last decade there has been a marked development of new and better fishing gear and technical solutions. Commercial technologies and know-how is also important for science, especially when focusing on areas that are out of the range of normal scientific equipment.

Submersibles
The remotely operated vehicle (ROV), the Aglantha, is used for marine biological and geological studies. The Aglantha was financed by Erna & Victor Hasselblads foundation. It was built and devlivered to UiB in 1998.

The ROV Bathysaurus
Bathysaurus is a remotedly operated vehicle (ROV) especially designed for the main MAR-ECO cruise. Find out more about this advanced technology.

Acoustic
RV G.O. Sars represents a new generation of marine research vessels. With its vibration- and noise-damped diesel generators and its propellers driven by directcurrent motors, RV G.O. Sars is an extremely quiet vessel under way. It emits 99 percent less noise under water than conventional research vessels.

Taking oceanographical measurements: using a CTD
Just as taking a person’s temperature tells something about their physiological status, so can taking the temperature in the ocean tell us something about the ocean. Other parameters, such as salinity, water density etc reveal information about water movements and productivity. Oceanographers routinely measure a number of parameters in order to learn more about the ocean.

Currents in the North Atlantic
Extreme conditions have made deep-sea exploration nearly as challenging as space exploration, and nearly as infrequent. The deep waters of the ocean, surprisingly, do not provide a uniform environment where marine organisms are uniformly distributed. They are affected by a number of topographical features that are much more dramatic than any found on land.
