- Arctic Sea Ice Age at Yearly Minimum (Years 1984-2021) (YouTube) – as seen in the Arctic Report Card 2021 video (credit: Eric Hackathorn, NOAA Global Systems Laboratory)
Description: Colors show the age of sea ice floating in the Arctic Ocean. The darkest blue areas on the map show seasonal or first-year ice, which formed during the most recent winter. White areas show where ice is more than four years old.
Scientists estimate the age of sea ice by combining satellite observations of ice locations and extent with buoy data on winds and motion. The temporal coverage for this data set is weekly data from January 1984 through December 2020. Data for 2021 comes from the Quicklook Arctic Weekly EASE-Grid Sea Ice Age data product.
The input ice motion data used for this data set is derived from the Polar Pathfinder daily 25 km EASE-Grid Sea Ice Motion Vectors Version 4 data set.
