Short summary
This research describes a detailed analysis of current distributions of spring phytoplankton communities in the Labrador Sea based on 10 years of observations. Phytoplankton community composition varied mainly according to the contrasting hydrographical zones of the Labrador Sea. The taxonomic distinctions of these communities influenced the photosynthetic and biochemical signatures of near-surface waters, which may have a profound impact on the carbon cycle in high-latitude seas.
