January 3rd nineteen scientists from Norwegian, Canadian and Polish institutions embarked RV Helmer Hanssen for a two week long expedition into the Barents Sea. Our science mission is to evaluate the winter time activity of the marine food web, from tiny bacteria and microalgae to fish. We are specifically interested in understanding any bi

Greetings from 78 degrees North! We have just spent 12 days on a research cruise for the PolarFront project onboard RV Helmer Hanssen collecting and identifying a variety of macrozooplankton and pelagic fish. We have also looked at fish stomachs and collected samples for stable isotope analysis to study trophic interactions.

When writing this it has been over a week since I left Tromsø to go on this research cruise to the polar front. Unfortunately, we do not have a dedicated marine mammal and seabird survey going on onboard as we have encountered a lot of wildlife over the past few days.
In terms of birds there is, of course, the “normal” stuff with northern fulmar
Den 15. august 2023 gikk forskningsfartøyet Helmer Hanssen ut fra Tromsø mot polarfronten med et team fra Akvaplan-niva, UiT Norges arktiske universitet, Memorial University og Equinor ombord. Forskningsfartøyet skal ta prøver på ulike stasjoner øst for Svalbard, fra 75 grader nord til 78 grader nord langs 29.5 grader øst.

After successful cruises to the Polar Front region in May 2021 and May 2022, a consortium of researchers this week left Tromsø aboard the UiT research vessel Helmer Hanssen to the Polar Front region of the western Barents Sea. This cruise is one of the very few exploring pelagic ecosystem dynamics during the Polar Night, a period rarely studied in the open Barents Sea. Apart from near-total darkne
Forskerne klør seg nå i hodet over hvorfor de om våren finner så få hoppekreps sør for polarfronten, men mange nord for fronten.
Den polare fronten
Ved den polare fronten møtes det atlantiske vannet i Barentshavet det polare vannet fra Polhavet. Det er så stor forskjell på vannet på hver side at forskerne kan måle hvor de passerer fronten. Det atlantiske vannet er saltere og har høyere tett
Ocean-based industries are in demand of current measurements
Upper-ocean current measurements are time consuming and expensive and the coverage of in situ measurements is sparse. Numerical models and remote sensing observations are dependent on verification with in-situ data. Ocean-based industries as well as research institutes are interested in well-modelled upper-layer ocean currents, as cur
MS student Frida Cnossen has been involved in the Polar Front project, led by Akvaplan-niva and funded by the Research Council of Norway. Frida participated in the May cruise of the Polar Front project. Based on cruise data she has now delivered her MS thesis 'Macrozooplankton distribution and pelagic fish feeding at the Barents Sea Polar Front' to the assessment committee at the Université Côte d
Algene i Barentshavet blomstrer og er fornøyde, sier forskerne. Det er godt nytt for alle dyrene som lever der.

Alger er havets planter. De bruker sollys for å lage oksygen og energi fra karbondioksid og andre stoffer i havet. Algene i havet lager rundt halvparten av oksygenet på jorda. De er også livsgrunnlaget for dyr, fisk
Forskerne i PolarFront er på tokt med FF Helmer Hanssen for å forske på livet i den polare fronten i Barentshavet. De forsker på livet i havet gjennom å ta prøver og bruke avansert teknologi.

The Polar Front project (2021-2024) is heading towards the polar front of the Barents Sea with the research vessel R/V Helmer Hanssen. The project will investigate the pelagic ecosystem using technologies like remotely controlled gliders alongside tradition sampling methods from the research vessel.

Akvaplan-niva has signed a contract with Kongsberg Maritime and ConocoPhillips to further expand the capabilities of the digital infrastructure "Blue Insight" (BI). The aim is to better serve the requirements for ecosystem monitoring that ocean industries meet. The collaboration builds on the established relationship in the GLIDER II project financed by ConocoPhillips. While the first part of the
