Summary

PolarFront is an open science project, designed to collect reference data on distribution, productivity, and food-web dynamics in the European polar front area, in the period 2021–2024.

The Barents Sea polar front, which often matches the southern extent of the seasonal ice zone, is known to be of particular importance for primary production, spawning, and feeding by various components of the pelagic ecosystem.

Using shipboard sampling and the Akvaplan-niva fleet of autonomous sampling platforms, the project will investigate this ecosystem during three seasons, including the poorly known Polar Night.

Open science

PolarFront is based on open science principles, with a commitment to publish all research articles and datasets as open access.

Data is managed in accordance with FAIR principles and W3C's best practices for publishing data on the web.

Industry and management end-user groups are integrated into the project to assure that scientific results have solid impact.

All of the project's datasets, presentations and publications are published continuously on Zenodo.

Funding

The project receives public funding from the Research Council of Norway, grant 326635 and has also received contributions from two partner petroleum companies, and logistical support from UiT The Arctic University of Norway and the EU project BioGlider.

Akvaplan-niva leading new project on Polar Front ecology

Akvaplan-niva has been awarded funding from the Research Council of Norway to study the role of the Polar Front in ecosystem structure and function in the western Barents Sea. The project has contributions from two petroleum companies, and logistical support from UiT The Arctic University of Norway and an EU project (BioGlider). The project period is November 2021 – December 2024.

To the Polar Front in the Polar Night

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

Gjennombrudd i bruk av autonom teknologi i studie av polarfronten

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.

Searching for macrozooplankton and fish in the Dark of Night

By: Maxime Geoffroy, Frida Cnossen, Einat Sandbank, Ingvild Ytterhus Utengen, and Paul Renaud
Part of the work conducted during the Polar Front campaign aims to understand the structure of pelagic communities across the Barents Sea Polar Front. These pelagic animals are comprised of fish living in the water column and macrozooplankton, drifting animals larger than 1cm. Pelagic animals play a c

Gelatinous plankton, like the hydromedusa Aglantha and the comb jelly Mertensia are voracious predators on smaller zooplankton. They catch their prey using extendible tentacles with special stinging or sticky cells and haul in the catch.

Not all zooplankton are copepods...

By Fredrika Norrbin, UiT The Arctic University of Norway
Did you know that tiny radiolarians, appendicularians living in temporary housing, and predatory arrow worms and jellyfish thrive in Arctic Seas in the Polar Night?
Copepod populations decline during winter, because the primary (plant) production is on hold, and predators are active. We may think of fish as the main enemies of zooplank

Arctic wildlife at polar front research cruise

By MSc student Lars Ursem (lars.ursem@wur.nl)
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

Update from the polar front (jelly)fish group

By Frida Cnossen and Ingvild Ytterhus Utengen, Akvaplan-niva
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.
