Sea ice variability and primary productivity in the Ross Sea,
Antarctica, from methylsulphonate snow record.
Geophysical Research Letters, 36, L10704.
doi:10.1029/2009GL037311.
The Ross Sea contains the most biologically productive
continental shelf in Antarctica and is a region where
the annual formation of sea ice drives substantial amounts
of bottom water formation. We present snow pit chemistry
data from Mt Erebus Saddle that provide a quantitative
proxy to reconstruct summer sea ice conditions and rates
of marine primary production. The methylsulphonate (MS) record
is strongly correlated with changes in the area of open water
(R2 = 0.903, p < 0.05) caused by differences in atmospheric
circulation and the sea-ice-damming effect of large icebergs,
B-15 and C-19, which calved from the Ross Ice Shelf in 2000
and 2002 respectively. Furthermore, MS and phytoplankton
net primary production correlate significantly (R2 = 0.927,
p < 0.01). Our results demonstrate the potential of the Mt
Erebus Saddle ice core to reconstruct sea ice and primary
productivity variability in the Ross Sea beyond the
observational record.
