Arctic Sea Ice Extent: March 30, 2023

March 30 2023:  Over the past week, the sea ice extent rose one more time on March 24th to 14.477 M km2, and then has been on a steady decline since then with a net decrease, since last week, by a relatively small rate at 0.82%, from the level on 03/23/2023 of 14.402 M km2 to 14.284 M km2 for this week; and so we may now be fully in the sea ice decline season

The negative sea ice anomaly this week was higher than the anomaly of -0.900 M km2 on 03/23/2023 to a lesser negative anomaly of -0.885 M km2 on 03/30/2023 and so less anomalously negative for this time of year.
