Odd parental feelings for several thousand herring eggs

To get a better impression how fishes will do under future conditions we decided to introduce fish larvae to the mesocosms. With that we will be able not only to record the interaction of several trophic stages under high CO2 conditions but also record the development of critical life stages such as the vulnerable larval […]

Evolution cage match

Microbes reproduce fast. Like, really fast, so that over the course of the mesocosm experiment, some species will go through about 50 generations. And in that time, evolution can happen. Team Evolution (Lisa and Sinead) are measuring how much some of the picoplankton in the mesocosms evolve. To do this, we need to measure the […]

All this money just for jacuzzis??

this is not a spa but a sophisticated experiment set up

Last wednesday after weeks of statistics and modelling, we (that is 7 students from GEOMAR) were kind of fed up with dry theory. So we got ourselves a bus + driver and headed north to experience science in action. After a one day trip we arrived at the marine station and found the whole KOSMOS […]

Every mesocosm needs a hoody!

Installing a roof on a KOSMOS mesocosm

In my opinion, our mesocosm only look complete with their hoody! Fortunately for me, a roof does not only serve an estathic purpose and we have to take the effort to install them before closing the mesocosm bags. It rains a lot in Bergen. You might have heard about Bergen being Europe’s rainiest city? I […]

KOSMOS circus in town

  With nearly 20 tonnes of mesocosm equipment and our boat Wassermann on board, the research vessel Alkor has arrived safely in Bergen on Sunday morning. An additional 14 tonnes of lab equipment and anchor weights for the mesocosm moorings were transported to Bergen by truck. After unloading Wassermann and taking on board the anchor […]

What’s it all about?

Those of you who visit us at Oceanblogs regularly have heard about ocean acidification¬†already – the change in ocean chemistry due to the uptake of carbon dioxide: Since the start of the industrial revolution, the ocean has absorbed approximately 30 per cent of all carbon dioxide released into the atmosphere by humans, for examply by […]
