June 2 2023: Over the past week, the sea ice had a decrease, since last week, by a higher rate of 3.96%, from the level on 05/25/2023 of 12.398 M km2 to 11.907 M km2 for this week. The negative sea ice anomaly this week was lower than the anomaly of -0.391 M km2 on 05/25/2023 to a greater negative anomaly of -0.582 M …
May 25 2023: Over the past week, the sea ice had a decrease, since last week, by a higher rate of 3.04%, from the level on 05/18/2023 of 12.787 M km2 to 12.398 M km2 for this week. The negative sea ice anomaly this week was slightly lower than the anomaly of -0.317 M km2 on 05/18/2023 to a greater negative anomaly of -0.391 …
May 18 2023: Over the past week, the sea ice decreased by a slightly lower rate of 1.96%, from the level on 05/11/2023 of 13.042 M km2 to 12.787 M km2 for this week. The negative sea ice anomaly this week was slightly higher than the anomaly of -0.403 M km2 on 05/11/2023 to a lesser negative anomaly of -0.317 M km2 on 05/18/2023 and …
May 11 2023: Over the past week, the sea ice had a decrease, since last week, by a slightly higher rate of 2.78%, from the level on 05/04/2023 of 13.414 M km2 to 13.042 M km2 for this week. The negative sea ice anomaly this week was slightly lower than the anomaly of -0.391 M km2 on 05/04/2023 to a greater negative anomaly …
Another data point has been added to one of Alaska’s longest and most unique climatological time series: The tripod on the Tanana river at Nenana fell over on May 8, triggering a clock that records the time of break-up. The tradition of betting on the timing of the river break-up was started in 1917 and …
May 4 2023: Over the past week, the sea ice had a decrease, since last week, by a slightly lower rate of 2.03%, from the level on 04/27/2023 of 13.690 M km2 to 13.414 M km2 for this week. The negative sea ice anomaly this week was slightly higher than the anomaly of -0.472 M km2 on 04/27/2023 to a lesser negative anomaly …
April 27 2023: Over the past week, the sea ice had a larger decrease, since last week, by a rate of 2.30%, from the level on 04/20/2023of 14.012 M km2 to 13.690 M km2 for this week. The recent daily up and down variability from the past few weeks now appears to have ended with a consistent sea ice decrease going on …
The negative sea ice anomaly this week was higher than the anomaly of -0.692 M km2 on 04/13/2023 to a lesser negative anomaly of -0.477 M km2 on 04/20/2023 and so less anomalously negative for this time of year.
The negative sea ice anomaly this week was higher than the anomaly of -0.940 M km2 on 04/06/2023 to a lesser negative anomaly of -0.692 M km2 on 04/13/2023 and so less anomalously negative for this time of year.
April 7 2023: Over the past week, the sea ice has continued to decrease, and since last week, by a rate at 1.62%, from the level on 03/31/2023 of 14.284 M km2 to 14.053 M km2 for this week. The negative sea ice anomaly this week was lower than the anomaly of -0.885 M km2 on 03/31/2023 to a grater negative anomaly of -0.940 …
