TLDR
Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems, and it appears that many organisms may exhibit endogenous rhythms that trigger fitness-maximizing activities in the absence of light-based cues.About:

Seasonal evolution of the albedo of multiyear Arctic sea ice : The surface heat budget of arctic ocen (SHEBA)
TL;DR: In this paper, the authors measured spectral and wavelength-integrated albedo on multi-year sea ice from a 200m survey line from April through October and observed changes in the evolution of albedos.

TL;DR: In this paper, the authors present a pan-Arctic compilation of available time-series data on vernal sea ice algal bloom development and identify the most important factors controlling its development and termination.

TL;DR: A multidisciplinary ecosystem-scale study from the polar night at 79°N documents a system with high activity levels and biological interactions across most trophic levels, and suggests a different perspective regarding ecosystem function that will be of importance for future environmental management and decision making.
Journal ArticleDOI
Moonlight Drives Ocean-Scale Mass Vertical Migration of Zooplankton during the Arctic Winter
TL;DR: Evidence is presented of an unexpected uniform behavior across the entire Arctic, in fjord, shelf, slope, slope and open sea, where vertical migrations of zooplankton are driven by lunar illumination.
Journal ArticleDOI
Phytoplankton dynamics in a changing Arctic Ocean
TL;DR: In this article, the authors highlight trends in primary production over the last two decades and consider changes to Arctic phenology by borealization and hidden under-ice blooms, and how the diversity of phytoplankton assemblages might evolve in a novel Arctic biogeochemical landscape.

The Ecological Role of Water-Column Microbes in the Sea*
TL;DR: Evidence is presented to suggest that numbers of free bacteria are controlled by nanoplankton~c heterotrophic flagellates which are ubiquitous in the marine water column, thus providing the means for returning some energy from the 'microbial loop' to the conventional planktonic food chain.

Phytoplankton growth, microzooplankton grazing, and carbon cycling in marine systems
Albert Calbet,Michael R. Landry +1 more
TL;DR: Analysis of the global impact of microplanktonic grazers on marine phytoplankton and its implications for remineralization processes in the microbial community shows potential ecosystem differences in micrograzer activity or trophic structure are a large uncertainty for biogeochemical models that seek to predict the microbialcommunity role in carbon cycling from bacterial parameters alone.
