Total sea ice cover on the Arctic Ocean peaked on March 7, satellite observations show, reaching a total area of 14.42 million square kilometers.

1) Japanese observations in the Sea of Okhotsk from 1934 (note that this area is relatively southerly, so if there's ice there, we can be quite sure there is lots of ice elsewhere):

One of the difficulties using charts based on in situ observations is that there was very little exploration poleward of the «marginal ice zone» (the area of partial sea ice cover near the ice edge), so in older reconstructions the ice concentration was often assumed to be 100 % beyond the marginal zone.

Or you could plot the fourth powers of the temperatures in K, approximate a uniform function that fits both periods taking into account what observations from sea ice and land area deglaciation and humidity levels tell us, and derive a metric.

Within the Outlook project, there may be differences in how each group obtains their area (e.g., model grid cells of varying resolution, sea ice charts, and satellite observations); each of these could produce a different value for ice extent.

In addition, the area of sea ice in the control run exceeds observations, which may increase the modelled sensitivity in the 1 — 4 × CO2 range.

In 1974, newly available satellite observations unveiled the presence of a giant ice - free area, or polynya, within the Antarctic ice pack of the Weddell Sea, which persisted during the two following winters1.
