During the fourth Chinese National Arctic Research Expedition cruise in summer 2010, a time-series
observation was carried out to examine the response of nutrients and phytoplankton community in the ice-water
interface to the ice melting ice in the central Arctic Ocean. Phosphate and silicate in the ice-water interface were
rich relative to dissolved inorganic nitrogen (DIN), based on the Redfield ratio (16N:1P:16Si), suggesting that DIN
was the potential limiting nutrient. DIN concentrations in the sea ice were about 3-4 times that in the surface
seawater, indicating that melting ice delivered DIN to the surface water. Pigment analysis showed that fucoxanthin
and chlorophyll
