Abstract Changes in the Arctic atmosphere, cryosphere and Ocean are drastically altering
the dynamics of phytoplankton, the base of marine ecosystems. This Review addresses four …

The decline of sea-ice thickness, area, and volume due to the transition from multi-year to
first-year sea ice has improved the under-ice light environment for pelagic Arctic …

Microalgae growing on the underside of sea ice are key primary producers in polar marine
environments. Their nutritional status, determined by their macromolecular composition …

Phytoplankton blooms in the Arctic Ocean's seasonal sea ice zone are expected to start
earlier and occur further north with retreating and thinning sea ice cover. The current study is …

Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the
interannual variability and long-term changes of the Barents Sea are well-documented, the …

The spring diatom bloom in the Arctic Ocean accounts for significant annual primary
production leading to the most rapid annual drawdown of water-column p CO2. Late-winter …

Phytoplankton cellular elemental quotas are important for evaluating the coupling of nutrient
cycles and assessing nutrient limitation in the ocean. While cell element quotas have been …

The central Arctic Ocean is rapidly changing due to amplified warming and sea ice retreat.
Nonetheless, it remains challenging to document and decipher impacts on key ecosystem …

Understanding the processes that shape the community structure of Arctic phytoplankton is
crucial for predicting responses of Arctic ecosystems to the ongoing ocean warming. In …

Biogeochemical cycling in high-latitude regions has a disproportionate impact on global
nutrient budgets. Here, we introduce a holistic, multi-disciplinary framework for elucidating …
