The role of iron as a micronutrient in the Antarctic sea ice environment ...
It is now understood that the Southern Ocean is a high-nutrient, low-chlorophyll zone; production being limited by the micronutrient iron (Fe). The seasonal formation and subsequent melt of Antarctic sea ice covers an area of approximately 17 million km2, an area roughly twice the size of the Austra...
