Incorporation mechanisms of iron and organic matter into newly-formed sea ice ...
Sea ice plays a critical role in the global ocean, including polar biogeochemical cycles and ecosystems. Importantly, sea ice serves as temporal reservoir for key nutrient iron (Fe), which is known to limit primary productivity in large parts of the Southern Ocean. Iron released from melting sea ice...
