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 [...] community, 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 [...] 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 communities, their molecular biodiversity and

This will [...] the consequences of silica decline for the Arctic marine ecosystem and the mechanisms responsible. To understand how climate change affects the Arctic Ocean, we will combine novel and classical approaches [...] Group Silicic acid Decline Effect on Marine Arctic Ecosystems SideEFFECT (Graphic: Mar Fernández-Méndez) Human-induced climate change is altering the ocean on a previously unimaginable scale.
