Figure 1 shows a comparison of the predicted September sea-ice extent (equivalent to the minimum) submitted by 38 contributions. This year the prediction of the University of Tokyo is the fourth from the lowest.

A comparison of the measured values of the daily Arctic sea ice extent is shown in Figure 7. The value for this year is smaller than 2012, which was at a record minimum.
The University of Tokyo provides the forecast for sea ice extent from July 1st.
