At least four key findings from these projects relating to arctic heterotrophic food web, pelagic - benthic coupling and biodiversity have emerged: (1) Contrary to a long - standing paradigm of dormant ecosystems during the long arctic winter, major food web components showed relatively high level of winter activity, well before the spring release of ice algae and subsequent phytoplankton bloom.

A long - lived paradigm in polar oceanography is that arctic pelagic ecosystems, characterized by short food webs, remain in a dormant state throughout most of the winter season beneath the sea - ice cover, which can last 8 — 10 months in some regions.
