Research cruise 2007

Be a virtual participant in some of the most exciting avant-garde research in Norway. In this web site you will be able to follow the researchers day by day and you will learn about how they undertake a scientific exploration of this fascinating environment.

See images and videos of the scientists at work, and ones from the hydrothermal vents themselves.

Learn more about hydrothermal vent systems and the organisms that live in this hostile environment.

    Day 1 - 25 June

    After breakfast, the ship moved from Nykirkenkaien to Laksevågkaien to load the final equipment supplies including the new ROV. This new ROV has better camera, lighting and sampling equipment and can dive to 3000m.

    Day 2 - 26 June

    The GOSars was repaired over night and we are en route to the waters north of Jan Mayen Island.

    Day 3 - 27 June

    Since heading north from Bergen we have lost the good weather. Things are pretty quiet as people try to get their sea legs.

    Day 4 - 28 June

    The uncomfortable sailing conditions continue. It is less choppy than before, but more rolling. Most are able to enjoy the excellent food on board – and perhaps the enforced moderation is good for us!!

    Day 5 - 29 June

    We have arrived at our first station. Everyone was on hand to watch the first CTD go down. It is equipped with three extra sensors brought by geochemical expert, Eric Olson from the University of Washington.

    Day 6 - 30 June

    We finished the CTD scanning last night, and headed north. We expect to be at our next location around 23.00 tonight. Then it's more CTD-scanning.

    Day 7 - 1 July

    The day started off at midnight (00:00). However, here in the land of the midnight sun, it could just as well have been 12:00 noon!

    Day 8 - 2 July

    It has been the busiest day yet for the scientists on board. Yesterday’s CTD series finished in the early hours with a second, even stronger, anomaly signature. There is definitely something down there.

  • Small images: 
    Day 9 - 3 July

    We have now completed three CTDs that indicate anomalies, and several that indicate nothing, enabling us to pin down the potentially "interesting" area more closely (please see map).

  • Small images: 
    Day 10 - 4 July

    Our nightly mapping and CTD series are showing increasingly interesting features.

  • Small images: 
    Day 11 - 5 July

    We continue to hunt our elusive hydrothermal zone with CTDs and the ROV.

    Day 12 - 6 July

    Today was the first day of poor weather. We had been told to expect foggy weather because this area is near a frontal zone of ocean currents, but while mostly overcast, the weather has been clear and the visibility good until today. However, our work does not depend on visibility so we continued as usual.

  • Small images: 
    Day 13 – 7 July

    The day started at midnight with the microbiologists and Christoffer Schander working on preserving and studying organisms from the recovered wood the ROV had brought up from 2900m.

  • Small images: 
    Day 14 – 8 July

    Around 06:00 the ship stopped battling the head wind and moved into a stationary position over the expected location of the CTD on the sea-floor (267m).

    Day 15 - 9 July

    A new group of researchers has come on board replacing some of the group from the first part of the cruise.

  • Small images: 
    Day 16 - 10 July

    We expect to reach Mohn’s Ridge and our research area around 18:00. Although the sea has been a little rough, the newcomers on board are managing really well.

  • Small images: 
    Day 17 - 11 July

    The wind has been increasing all day and is now up to 17-20m/s. The waves are too high to be able to safely launch the ROV or to be able to undertake the core sampling we had planned.

  • Small images: 
    Day 18 - 12 July

    The wind has dropped and we are again able to set the ROV in the sea. We first dove to the northern face of the seamount. Here the slope surface is made up of landslide debris consisting of chunks of rock of various sizes.

  • Small images: 
    Day 19 - 13 July

    Before we finish the cruise we hoped to dive to the deepest part of this volcanic rift valley. Is today the day for such a venture? The wind is beginning to increase and the wave height as well … In addition, it is Friday the 13th!

  • Small images: 
    Day 20 - 14 July

    The southern face of the 2500m seamount was mapped overnight. The map shows steep cliffs that were created by movements along fault lines. Such fault movement results in earthquakes.

  • Day 21 - 15 July

    The wind and wave conditions made it too difficult to take any last sediment cores.
