In the Field
Field expeditions are a critical part of CGB's activities. In the field researchers collect data to support or disprove ideas they are working on. Successive field trips allow the researchers to build up clearer pictures of the geology, the biology and the geobiology of the area in question.

Summers 2006 and 2005 had important research cruises that found the first active vents north of Iceland in relatively shallow waters north of the Island of Jan Mayen.

Vent discoveries: shallow volcanoes and new hydrothermal fields
The 2013 summer cruise was extremely fruitful: at least five new venting areas were located and a large shallow volcanic area was explored. The goal of the Arctic marine expedition was to investigate the areas west and northeast of Jan Mayen Island. Here, in the middle of the Norwegian-Greenland Sea, the Arctic Mid-Ocean Ridge (AMOR) passes this volcanic island. Oceanic crust is formed along the AMOR by volcanic and tectonic activity at a rate of around two cm. per year.

French vessel Pourquois pas? Cruises the Mid-Atlantic Ridge
CGB scientists Cedric Hamelin and Kristian Haaga are aboard the French IFREMER’s research vessel the Pourquoi pas?, investigating the detachment fault system at 13 degrees North on the Mid-Atlantic Ridge.

Fieldwork 2011Small images:
In Summer 2011 CGB had a 3-leg research cruise, PhD student Eirik Gjerløw spent a month on Jan Mayen Island, and Steffen Jørgensen spent 2 months at sea.

Research cruise 2010Small images:
The first part 24 June – 2 July, led by Haflidi Haflidason, will employ the Calypso coring technology to extract up to 20m sediment cores. The second part 5-20 July will stop briefly at the Håkon Mosby Mud Volcano and Loki’s Castle for sample taking before heading north and west along the Knipovich Ridge to look for new sites of hydrothermal activity using AUV technology to support the traditional CTD and ROV work.

Fant verdens dypeste varmekilde
– Stemningen ombord var en blanding mellom ekstase og høytid, sier professor Rolf-Birger Pedersen ved UiB som var med på toktet.

Research cruise 2009Small images:
1-11 August CGB researchers are climbing aboard aboard the Norwegian RV, G.O.Sars and are heading to sea again to re-visit Loki's Castle, the world's northernmost identified Black Smoker, and Håkon Mosby Mud Volcano, one of the world’s largest underwater mud volcanoes. This year a production team will be onboard filming a segment for Discovery Channel's series: ”Mighty ships” [in action].

Cruising in the South Pacific
Professor Lise Øvreås is participating in a research cruise in the Lau basin, east of Fiji, where scientists are investigating extreme organisms living around the hydrothermal vents found there.

Drilling 2008Small images:
Summer 2008, CGB researchers travelled to the Barberton Mountain Land in South Africa to carry out scientific drilling in some of the oldest rocks on Earth. Working with colleagues from the Africa Earth Observatory Network, University of Cape Town they drilled into rock that is c. 3.4-3.5 billion years old to investigate early life and environments on ancient earth.

Research cruise 2008Small images:
Summer 2008 the G.O.Sars headed north once more with students and scientists from a variety of disciplines including geology, geochemistry, biology and microbiology. There were five teachers on board who worked closely with the scientific crew and who were responsible for maintaining a daily journal.
