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 challenged this. We examined the zooplankton community present in Svalbard fjords, coastal waters, and the shelf break north of Svalbard, during the polar night. We focused on the population structure of abundant copepods (Calanus finmarchicus, Calanus glacialis, Metridia longa, Oithona similis… 

Seasonal mesozooplankton patterns and timing of life history events in high-arctic fjord environments

Seasonal patterns in mesozooplankton composition, vertical distribution, and timing of reproduction are challenging to study in the open sea due to ocean currents and mix of populations of different

Pelagic ecosystem dynamics between late autumn and the post spring bloom in a sub-Arctic fjord

Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round basis, including the poorly studied winter period. To improve the knowledge base for

Life cycle of Oithona similis (Copepoda: Cyclopoida) in Kola Bay (Barents Sea)

There were positive relationships between abundance, EPR, SEPR, production and water temperatures, and Reproductive parameters appeared to be controlled by hydrological factors and food conditions.

Plankton community structure and role of Oithona similis on the western coast of Greenland during the winter-spring transition

Assessment of the species' trophic role in Greenlandic coastal waters during the winter-spring transition and observations of egg production rates and efficiencies confirm that O. similis is active and successfully reproductive in food-limited winter conditions, stressing that it is a key component of Arctic and subarctic communities throughout the year.

We investigated the population dynamics of a small and little-studied harpacticoid copepod, Microsetella norvegica, in a sub-Arctic Norwegian fjord (Balsfjord 69°N). We sampled with a 90 μm mesh WP-2

This work reports on the seasonal ecology and life strategy of a predatory plank- tivore in a high-Arctic fjord (Billefjorden, Svalbard ~78° N), and studies the chaetognath Parasagitta elegans, an abundant zooplankter of high-latitude seas, focusing on its age structure, seasonal vertical distribution, growth and timing of reproduction.
