The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate
earlier seasonal primary production. This earlier growing season may be accompanied by …

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 regular movements of waves and tides are obvious representations of the oceans'
rhythmicity. But the rhythms of marine life span across ecological niches and timescales …

Marine ecosystems at high latitudes are characterized by extreme seasonal changes in light
conditions, as well as a limited period of high primary production during spring and early …

Marine macrophytes are the foundation of algal forests and seagrass meadows–some of the
most productive and diverse coastal marine ecosystems on the planet. These ecosystems …

The current understanding of Arctic ecosystems is deeply rooted in the classical view of a
bottom-up controlled system with strong physical forcing and seasonality in primary …

The ongoing uptake of anthropogenic carbon by the ocean leads to ocean acidification, a
process that results in a reduction in pH and in the saturation state of biogenic calcium …

In extreme high-latitude marine environments that are without solar illumination in winter,
light-mediated patterns of biological migration have historically been considered non …

Abstract The Arctic Ocean features extreme seasonal differences in daylight, temperature,
ice cover, and mixed layer depth. However, the diversity and ecology of microbes across …

Sea ice primary production is considered a valuable energy source for Arctic marine food
webs, yet the extent remains unclear through existing methods. Here we quantify ice algal …
