Part 3 Methane seeps

Main content

So little is known about methane seeps鈥� In part 3, researchers will use the GOSars state-of-the-art technology to sample, map and document some methane seeps located on Norway鈥檚 continental shelf. What is making the pockmarks and the pingos? Is it possible for the seeps to be a future energy source?

Departure from Bod酶

28.07.2008 The main purpose of this part of the cruise is to study pockmarks in the Nyeggaarea, at the continental shelf outside Tr酶ndelag. The study, which is a part of the GANS project, is to take samples from ocean bed, and study de marine fauna with help from the ROV.

Heading for the field

29.07.2008 During this wonderful day, the boat has made a couple of halts to carry through a CTD, a Boxcore- and a Multicore-test. The CTD gives the multibeam-echo-sounder information about salt contents, temperature, depth of the ocean and density .These factors are essential for the Multibeams...

A grey day, but the mood is still on top

30.07.2008 Another quiet day for the biologists while the geology students Marte, Mats and Svanhild are faithfully monitoring 鈥� with help from their supervisors Berit and Haflidi.

A hectic day on the field.

31.07.2008 鈥滻鈥榤 not moderate anymore!鈥� I鈥檓 absolutely sure every time I open my mouth, and uncertain when I close it鈥�, that can be a suitable saying. It鈥檚 not given to everyone to pick up all information and get up early not to miss any action. As one of the diary writers, who got up at 05.00 a.m....

The ocean is a little rough, but the deep-sea sampling continues.

01.08.2008 "Rock on" 鈥� literally spoken. For most of us, the waves in the sea are a little too much today. Anyway, most of the researchers are able to do their work, they are taking new samples from the sediments of the seafloor, and geologists supervise it all from the control room. Someone skip...

A windy day.

02.08.2008 Moderate gale and sometimes gust of wind up to 22 mps. G.O. Sars is a big and rugged boat, but the big waves create challenges for several on board. Not everybody are used to the heavy sea, and several pale faces are observed in the corridores. The researchers use the day to sum up, mark...

Happy days at the microlaboratory

04.08.2008 The waves won鈥檛 stop rolling, even though the sun is shining from a quite bright sky. Therefore this is yet another day without ROV-dives. More samples are taken up by the other instruments, from proximally the same area as yesterday.

A lot of beatiful things to see on 700 meters depth.

05.08.2008 There have been a lot of exciting ROV-dives today; identification of a new type of leech (we think) and how the microbiologists received some help from a teacher. There have been a lot of sampling the last days, and for the microbiologists, there has been a rough drive for registering...

Another day with more samples

06.08.2008 A little rain in the morning, but the weather stay calm throughout the day. More discoveries were made today, which made the geologists happy. During the night the TOPAS profiles ran through most of the pockmarks. With Berit and Mats monitoring, they made 100 km of mapping.

Against the end of the cruise

07.08.2008 There are cleaning and washing, but still continuing to take samples from the seabed. There is full activity on every deck on board the G.O. Sars today. Everybody have to clean up their working area; the boat has to be able to welcome new people from the Nor-Fishing mess which will be...

The last day of the cruise

08.08.2008 G.O. Sars arrive Trondheim and Haflidi gather everybody on deck 5 to say a few final words and give thanks to the contributors. The boat is not allowed to be placed by the dock before lunch, therefore, the Captain use this opportunity to initiate a firedrill...
