A Hidden Arctic Ocean Crisis Is Unfolding Beneath the Melting Ice

Scientists say Arctic sea ice loss may have pushed the Fram Strait into a new nutrient regime, with nitrate levels falling since around 2009.

Researchers link the decline to more sunlight reaching shallow shelf waters and stronger benthic denitrification after sea ice retreat.

Lower nitrate could curb phytoplankton growth, favor smaller species, and weaken the Arctic Ocean’s role in absorbing carbon.

The shift may ripple through fish stocks and North Atlantic ecosystems if the trend continues.
