Winter times

In our second scientific publication you can read about the overwintering of Calanus finmarchicus. This small copepod migrates down to 800 m or more, and spends many months at this depth before coming to surface waters again!

We analyzed data from 11 winters in the Norwegian Sea and found that climatic changes in as far away as the Labrador Sea can determine how many copepods and herrings we can find in the Norwegian Sea.

Copepods from space

In our first scientific publication we show that the pigments of the small (ca. 3 mm) crustacean Calanus finmarchicus are visible from space!

These findings will help us to learn much more about zooplankton patches. How often do large surface patches occur? Do they follow the phytoplankton bloom? Are they purely shaped by oceanic currents? All these questions, which have been very difficult to answer based on traditional sampling methods, will now be much more easy to understand.


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.
