Observations of sea ice show that sea ice volume, extent and concentration are all decreasing and that the rate of decline is steeper in recent decades versus earlier ones. However, variations in year to year sea ice extent makes yearly forecasts difficult, limiting human activity in the Arctic. One major influence on sea ice concentration in the Chukchi Sea is the flow of heat through the Bering Strait (R~ 0.8 in April to June) which has been found using the A3 mooring in the Bering Strait. We find that in May through August the SODA reanalysis correlates well with the A3 mooring (R~ 0.4 - 0.6) and better when detrended (R~ 0.5 - 0.7). As data from the A3 mooring is more limited than data in SODA, we ask if SODA is a viable method for predicting sea ice extent in the Chukchi Sea.
