Recent studies have shown that the biological activity during the Arctic polar night is higher than previously thought. Zooplankton perform diel vertical migration during the dark period/winter, with the calanoid copepods Calanus spp. being one of the main taxa assumed to contribute to the observed diel vertical migration. We investigated the sensitivity of field-collected Calanus spp. to irradiance by keeping individuals in an aquarium and exposing them to gradually increasing irradiance in… 

Disruption of marine habitats by artificial light at night from global coastal megacities

Half of globally significant megacities are situated near the coast, exposing urban marine ecosystems to multiple stressors such as waste-water discharge containing a host of organic and inorganic

Bioluminescence potential during polar night: impact of behavioral light sensitivity and water mass pathways

During polar nights of 2012 and 2017, bioluminescence (BL) potential surveys demonstrated high emissions at depths around and below 100 m at offshore stations to the north of a Svalbard fjord

High abundances of small copepods early developmental stages and nauplii strengthen the perception of a non-dormant Arctic winter

The traditional view is that the Arctic polar night is a quiescent period for marine life, but recent reports of high levels of feeding and reproduction in both pelagic and benthic taxa have

Loss of buoyancy control in the copepod Calanus finmarchicus

It is proposed that salinity, temperature and hydrodynamics of the physical environment, in conjunction with the biophysical properties of lipids, explain periodic high abundances of lipid-rich copepods in surface waters.

Why artificial light at night should be a focus for global change research in the 21st century

It is concluded that the growing use of night-time lighting will continue to raise numerous ecological, human health and cultural issues, but that opportunities exist to mitigate its impacts by combining novel technologies with sound scientific evidence.

Circadian Clock Involvement in Zooplankton Diel Vertical Migration

Introduction to the special issue on polar night studies conducted onboard RV Helmer Hanssen in the Svalbard area

Polar night studies at high latitudes have during the last years become a major research focus for ARCTOS researchers, spearheaded by research cruises lead by UiT and MSc/PhD courses lead by UNIS, and the prevailing view of the polar night as devoid of biological activity has recently been challenged.

Glowing in the dark: discriminating patterns of bioluminescence from different taxa during the Arctic polar night

AbstractResearch since 2009 has shown that despite almost total darkness during the Arctic polar night, there is much more biological activity than previously assumed, both at the sea surface, water
