This has a direct impact on Arctic microorganisms as more light is available [...] new production. In addition, ocean warming is leading to changes in the winter mixed layer in the North Atlantic, which has reduced the amount of silica entering the Arctic Ocean in recent decades. This

Molecular Sea Ice Ecology Polar oceans are seasonally covered by sea ice with an average size of the continent of North America. Despite harsh conditions therein, sea ice and its lower surface can carry [...] typically dominated by Diatoms. Sea ice can provide important primary production to polar oceans via these communities, although they are often very patchy. In times of declining sea ice coverage it is a major [...] major challenge to determine current sea ice biodiversity, functions provided by its biota, and the future of sea ice communities in a warming ocean. We address these questions through analyses of total
