Barents Sea

Ice around Franz Josef Land washed out due to warmer waters from the west while the multiyear ice continues to erode forming rotten ice. Mobile Ice in the Barents North West continues to track south and east with movement of the ice edge averaging extensions of 28NM up to 37NM in some portions.

East Siberian Sea

Remnant multi year ice remains to the west of Wrangle Island. Northerly melt back continues as ice in the northwestern region remains consolidated.

Thumbnail image of Greenland Sea Synopsis PNG

The Greenland Sea continues to melt out as the ice edge has receded northward. Areas of first year ice have melted and all that remains is multiyear ice.

High Arctic

No synopsis write-up for the High Arctic as it remains consistent throughout this part of the year. A synopsis write-up will begin during summer months as ice retreats and becomes more dynamic in the region.

Thumbnail image of Hudson Bay Synopsis PNG

Hudson Bay

Eastern Foxe Basin contains small amounts of thick first year ice. Hudson Bay and James Bay are ice-free. Hudson Strait is bergy water.

Thumbnail image of Kara Sea Synopsis PNG

Kara Sea

Sea ice has rapidly melted back and drifted north, resulting in the ice edge receding by over 100NM in some locations. Pack ice remains west of Severna Zemlya and east of Franz Joseph Land.

Laptev Sea

The multi year ice pack remains consolidated as easterly drift continues.
