  • This graph shows PIOMAS Arctic sea ice volume (SIV) from January 1979 through the latest monthly update.
  • Each year in the record comprises one complete circuit.
  • Daily SIV values were averaged over sequential and non-overlapping seven-day periods for smoothing purposes. (Each complete circuit is actually comprised of 51 separate week-long line segments, plus a single eight-day segment to equal 365 days.)
  • The vertical axis shows the years in the record, with the earliest year (1979) at the top and the current (or most recent) year at the bottom.
  • The grey circles on the base reflect SIV in thousands of cubic kilometers (km3).
