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!
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.
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.
We just came back from a very successful cruise to the area outside Lofoten-Vesterålen islands, where we were looking for (and finding!) patches of the small zooplankton Calanus finmarchicus. View some pictures in the gallery.
