October 27, 2022: Over the past week, the sea ice has continued to increase at a higher rate from last week of 13.58%, from the level on 10/20/2022 of 6.893 M km2 to 7.976 M km2 for this week; a pretty healthy increase over a week period. The negative sea ice anomaly this week was less than the anomaly of -1.724 M km2 on …
October 20, 2022: Over the past week, the sea ice has continued to increase at a higher rate from last week of 10.66%, from the level on 10/13/2022 of 6.158 M km2 to 6.893 M km2 for this week. The negative sea ice anomaly this week was less than the anomaly of -1.802 M km2 on 10/13/2022 to a less negative anomaly of -1.724 M …
October 13, 2022: Over the past week, the sea ice has continued to increase by a slightly lower rate from last week of 8.59%, from the level on 10/06/2022 of 5.629 M km2 to 6.158 M km2 for this week. The negative sea ice anomaly this week was greater from the anomaly of -1.698 M km2 on 10/06/2022 to a more negative anomaly …
October 6, 2022: Over the past week, the sea ice has continued to increase by a greater rate from last week of 8.90%, from the level on 09/29/2022 of 5.128 M km2 to 5.629 M km2 for this week. The negative sea ice anomaly this week was greater from the anomaly of -1.657 M km2 on 09/29/2022 to a more negative anomaly of -1.698 M …
September 29, 2022: over the past week, the sea ice has continued to increase by a greater rate from last week of 5.69%, from the level on 09/22/2022 of 4.836 M km2 to 5.128 M km2 for this week, and so we are now solidly (no pun intended) in the sea ice growth season. The negative sea ice anomaly this week was greater …
September 22, 2022: over the past week, the sea ice has now increased by a rate from last week of 3.70%, from the level on 09/15/2022 of4.657 M km2 to 4.836 M km2 for this week. It turns out that the sea ice bottomed out only one day after last week’s report on 09/16/2022 with the final minimum sea ice extent level of 4.650 M km2); …
A powerful storm has caused severe and widespread damage along Alaska’s West Coast. As of early morning on Sunday, September 18, water levels are receding along the Bering coast but still rising along the Chukchi coast as ex-typhoon Merbok moves northwards. Coastal communities all along the West Coast from the Kuskokwim delta to Norton Sound …
September 15, 2022: Over the past week, the sea ice has now decreased by a bit of a higher rate from last week of 4.00%, from the level on 09/08/2022 of4.851 M km2 to 4.657 M km2 for this week. We should be close to bottoming out for the year and at this point we are still just below the 2021 sea ice …
September 8, 2022: Over the past week, the sea ice has now decreased by a lower rate from last week of 3.48%, from the level on 09/01/2022 of 5.026 M km2 to 4.851 M km2 for this week. Perhaps the slow-up of the past couple of weeks is a harbinger that we are really close to bottoming out for the year. …
Cool and wet weather patterns in August brought the unusual 2022 fire season to an end in much of the state. Acreage burned and the number of total fires increased only moderately over the last weeks. However, dry conditions persist in parts of the Interior and late season lightning caused several new fires in August, …
