These are the two chambers we use. The oxygen electrodes are the rods you see coming out on the right side of the chambers… The temperature in the surrounding water is kept stable by a heater with a thermostat (the grey box), and a cooler (not visible). We regulate light intensities by shadowing with decreasing layers of black nets (above the chambers) until full light.
These past days have been really hectic. We’ve had our share of problems. Yesterday, one of the thermostats supposed to govern one of the 10 C batches started whining – really high pitched tone. I turned both the cooler and the thermostat off and went home, being as the culture room itself holds about 10 C. I spent the night in agony, really wondering why the fuck I bother doing this. On top of that frustration the lighting in the culture room was off today, and we discovered even more problems…

This is kind of slow at first, but really picks up… Watch it! You will not regret it. Sit back and enjoy the wonderful pictures, the excitement and one hell of an explorer :) Kudos, Edith Widder!

For the science stuff;
Wow, this weekend was really great! On Friday I was really exhausted and went right home from the University (RUC), ate dinner and crashed in my room. I love to hang with Hartvig and Stein, but I need time by my lonesome from time to time – again, there is no doubt about that :)
I decided to take some time off to see Roskilde. That is, to see Roskilde without dirty beer drinking music lovers that usually take over the town in summer (Roskildefestivalen). Although I’ve been to that event a couple of times (:D and love it!) I must say it is much lovelier this time of the year with the beautiful blooming gardens and clean streets…
On Saturday I went to see the Roskilde Cathedral. It was huge! Even though I’m not a religious person it struck me with awe… – All the kings and queens that lies there dating back to the end of the year 900… gives me goose bumps. For anyone visiting the town I would recommend at least a short visit (and to you mamma, if you read this, I WILL get you pictures in time, just didn’t bring my camera this time around…). More info on the Cathedral can be found here: Roskilde Cathedral.
On Sunday I visited the great Museum of Vikingships in Roskilde. More info on that can be found here: Vikingeskibsmuseet. It was quite similar to the one found in Oslo, but I dare say (I’m sorry) a bit fresher with their state of the art buildings. I’ll post some pictures very soon.
I actually didn’t know that Roskilde and the area around played such an important part in both Danish and Scandinavian history. I learned a great deal. The five ships that are put on display were excavated from 1957-1959. The ships were sunk (probably in summer 1079) as part of an under water defence. The construction would force incoming ships to take routes where they more easily could be discovered by land posts. The need for these massive measures arose with the increasing threats of a Norwegian attach. Historians assume that an attack sprung out from Kragerø in Norway actually took place around this time.
Even more fascinating, I think, is the display of a reconstruction of one of these ships. It is a long ship they have called Havhingsten or the Sea Stallion of Glendalough (the original ship was probably built in Dublin in the year 1042).
The reconstruction was sailed (and rowed) from Roskilde, via Norway, the Orkney Isles and Scottland through storm and seasickness all the way to Dublin where it was displayed for 10 months. From there on, it journeyed through the Celtic Sea, the English coast to Holland and the North Sea and back to Denmark. Quite impressive. It must have been quite a ride! :) More info about this project can be found here: Havhingsten.
Well, it finally happened. My trip to Roskilde was set. Just before, or more correctly in the beginning of our Easter holiday, I got the message: You are expected. I had to jump into my field gear, ditch all other plans and catch a plane to Bergen (the west coast) to collect some juvenile kelp (- about 200 individuals!)… One of my supervisors joined me a couple of days later by car to Grimstad in the south to get some individuals from there as well. Just before leaving for Denmark we collected some individuals from Drøbak (close to Oslo). On April 7. my two supervisors and I drove down from Oslo to Roskilde, which is my current location :) Next week it’s down to business. Hard core science! I’m going to run PI-curves (by O2 measures) at 10, 15 and 20 C to see where the point of compensation lies (where photosynthesis in the kelp meets its respriation). Then we’re going to let the kelps acclimatise for two weeks at 10, 15 and 20 C to run another set of PI-curves. EXCITED! The results may provide the backing I need for stating my hypothesis on why the kelp is disappearing – with confidence!! :D
Today we had a breakthrough at Marinbiologene DA. The first sketchy parts of our blog was formed, and it is already starting to look promising. Next out is getting our website up and running. Really looking forward to that. The idea that brought forth this project was first conceived in 2006. It’s been on hold partly because we didn’t quite know where to begin and partly because of other work that had to be done. Our aim is to establish a base of information concerning research on marine biology in Norway, monitoring, conservation and management of our coastal systems and to educate people on the importance of caring about the marine environment. These are our first baby steps…
