Continued increases in Arctic Ocean primary production

Dramatic declines in sea-ice cover in the Arctic Ocean in recent decades have the potential to fundamentally alter marine ecosystems. Here we investigate changes in sea ice between the years 1998 and 2012 at regional and basin scales and how these have impacted rates of phytoplankton net primary production (NPP). Annual NPP increased 30% over the Arctic Ocean during our study period, with the largest increases on the interior shelves and smaller...
