Graph of the Day: Date of Freeze-up for Wales/Bering Strait, 1979-2007
Date of freeze-up (day of year) for Wales/Bering Strait from passive microwave satellite data (Kapsch and Eicken, unpublished data). The time series shows a delay in onset of freeze-up (statistically significant at the 95% level) parallel to the substantial changes in summer minimum ice extent observed over the same time period.
