Regional charts and associated synopsis write-up capture ice and environmental conditions throughout the Arctic which are based on the U.S. National Ice Center’s weekly analysis. Charts and synopses are updated weekly on Fridays. Note: Baltic Sea analysis is provided by the Finnish Meteorological Institute. The Canadian Archipelago (Canada East, Canada North, Canada West, and Hudson Bay) analysis is provided by the Canadian Ice Service.
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.
The Arctic Ocean consists of old ice. The mobile ice in Nares Strait consists of mostly old ice with some first-year ice with significant transient new ice. The remaining mobile ice throughout the Queen Elizabeth Islands is a mixture of old ice, firstyear ice and transient new ice. Jones Sound is predominantly bergy water with some old ice remaining in its eastern and western sections. Lancaster Sound, Baffin Bay and Davis Strait contain bergy water. The remaining ice in the Gulf of Boothia and Committee Bay is first-year. Prince Regent Inlet consists of bergy water.
The ice around the Queen Elizabeth Islands is mobile with mostly old with some first-year ice. The ice in the Peary Channels is all old ice. Penny Strait and Queens Chanel are mostly open water with a mix of old ice. Viscount Melville Sound contains a small area of first-year ice with old ice moving south from Byam Martin Channel. Low concentrations of old ice persist north of Banks Island in M’Clure Strait. Barrow Strait has open water, ice-free, and bergy water conditions. M’Clintock Channel is mostly ice free with a small concentration of mobile old ice off the southern shore of Victoria Island, north of Pelly Point. Victoria Strait, Peel Sound, and Larsen Sound are ice-free. Amundsen Gulf, Dolphin, Union Strait, Coronation Gulf, and Queen Maud Gulf are ice-free. The Canada Basin contains old ice with some new ice filling in between the floes. The Beaufort Sea contains predominantly old ice north of 72N while the south portion is open water to ice-free. There’s an area of bergy water north of 72N and between 146W and 159W. The areas along the Yukon coast and the Alaskan Coast are ice-free.
