Potential effects of climate change on the distribution range of the main silicate sinker of the Southern Ocean
Abstract Fragilariopsis kerguelensis , a dominant diatom species throughout the Antarctic Circumpolar Current, is coined to be one of the main drivers of the biological silicate pump. Here, we study the distribution of this important species and expected consequences of climate change upon it, using...
