Nutrient availability limits phytoplankton growth throughout much of the global ocean. Here
we synthesize available experimental data to identify three dominant nutrient limitation …

Approximately 45% of the photosynthetically fixed carbon on Earth occurs in the oceans in
phytoplankton, which account for less than 1% of the world's photosynthetic biomass. This …

Half of the Arctic Ocean is deep sea (> 1000 m), and this area is currently transitioning from
being permanently ice-covered to being seasonally ice-free. Despite these drastic changes …

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 …

Marine plankton form complex communities of interacting organisms at the base of the food
web, which sustain oceanic biogeochemical cycles and help regulate climate. Although …

Unprecedented quantities of heat are entering the Pacific sector of the Arctic Ocean through
Bering Strait, particularly during summer months. Though some heat is lost to the …

Nutrient supply to the surface ocean is a key factor regulating primary production in the
Arctic Ocean under current conditions and with ongoing warming and sea ice losses. Here …

The hydrography of the Arctic Seas is being altered by ongoing climate change, with knock‐
on effects to nutrient dynamics and primary production. As the major pathway of exchange …

Abstract Phytoplankton in the Arctic Ocean are subject to nitrogen limitation in the summer,
however, how severely the nitrogen stress affects phytoplankton physiology remains largely …

Climate change has led to a~ 40% reduction in summer Arctic sea-ice cover extent since the
1970s. Resultant increases in light availability may enhance phytoplankton production …
