Arctic river dissolved and biogenic silicon exports - current conditions and future changes with warming ...
Silicon (Si) exports from terrestrial to marine systems can dictate phytoplankton species composition in Arctic coastal waters. Diatoms are often the dominant autotroph in Arctic waters, making Si an important control on Arctic marine primary productivity. Yet, even as Arctic regions are among the f...
