Effects of Snow and Remineralization Processes on Nutrient Distributions in Multi?Year Antarctic Landfast Sea Ice

We elucidated the effects of snow and remineralization processes on nutrient distributions in multi-year landfast sea ice (fast ice) Lützow-Holm Bay, East Antarctica. Based sea-ice salinity, oxygen isotopic ratios, thin section analyses, we found that fast grew upward due to year-by-year accumulation snow. Compared seawater origin, concentrations shallow were low replacement by clean fresh In deeper origin (the lower half column), was dominated degradation organic matter. By comparison between first- muti-year ice, biological uptake relatively young older respectively, under physical process brine drainage.
