Research Days 2018

Every year in autumn there is a week of research days in Norway, when people can learn about ongoing research at universities and elsewhere.

This year, amongst other things kids and pupils could find out how plankton aggregates, and how the zooplankton Calanus finmarchicus avoids predation by fish.

Completed this years sampling

Map of Study area

During this years research cruise from 16-27 June we performed sampling along 6 transects and at 18 stations, using a variety of sampling instruments. See who participated at the intense sampling here.

Our first study area was off the coast of Vesterålen islands, where we found high numbers of our key study species, the copepod Calanus finmarchicus.

After completing sampling there, we moved to study patches of this species at Tromsøflaket, a known fishing hot spot.

See what can happen to plankton swarms

Researches from Oregon State University have been able to film blue whales gulping swarms of krill:

But which swarm is worth feeding on from the whales’ perspective?

“Every time a blue whale opens its mouth, it’s like putting on the brakes, it slows way down so these animals have to make decisions about what’s worth opening their mouth for.” says Dr. Torres.

And from the planktons´ perspective, what is the benefit of forming swarms when it apparently does not yield protection from predators? This is a question we are going to address during Sea Patches.
