In Roskilde doing Science

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

Kelp Forest Ecology – Why I Bother

The kelps and their associated epiphytes are some of the most important habitat forming structures and productive areas in the marine systems. As shelter and food source they are able to support an immense number of faunal individuals. Kelps have historically dominated the rocky shores of Norway, which means along most of our 83 281 km stretch of coastline. Considering the total area of Norway (385 199 km² including Svalbard) that is… very long. However, our two most dominating kelp species are currently struggling to survive.

Laminaria hyperborea, wich dominated the wave exposed areas, have been…
