This study provides the first inventory of extracellular organic carbon during a bottom-ice algal bloom at Turtle Rock, Antarctica, in the spring-summer transition (November-December, 2011). We analysed the distribution and properties of extracellular carbohydrates represented by dissolved organic carbon and the distributions of mono- and polysaccharides, in relation to the physico-chemical brine environment and algal growth characteristics. These analyses provide clues in understanding the mechanisms and functions of algal extracellular organic carbon exudation in Antarctic bottom-ice communities.
