We present snow pit chemistry \r\ndata from Mt Erebus Saddle that provide a quantitative \r\nproxy to reconstruct summer sea ice conditions and rates \r\nof marine primary production. The methylsulphonate (MS) record \r\nis strongly correlated with changes in the area of open water \r\n(R2 = 0.903, p < 0.05) caused by differences in atmospheric \r\ncirculation and the sea-ice-damming effect of large icebergs, \r\nB-15 and C-19, which calved from the Ross Ice Shelf in 2000 \r\nand 2002 respectively. Furthermore, MS and phytoplankton \r\nnet primary production correlate significantly (R2 = 0.927, \r\np < 0.01).
