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.
Due to a low pressure system over the past week, Svalbard and Franz Josef Land have experienced persistent easterly winds of around 20 knots, with gusts of 30 knots. The strong winds continued to have a substantial impact on ice conditions throughout the islands. Air temperatures across Svalbard have generally remained too mild to support significant new ice formation, leaving the surrounding sea ice notably degraded.
As storms continue to move across the Kamchatka Peninsula, bringing warmer temperatures and strong winds, the sea ice there is melting and being pushed along the coast. These storms are having the opposite effect in the Bering Sea, as they either move northward or dissipate, allowing cold air to move south. This, in turn, is pushing the ice edge farther south.
The Labrador Sea is bergy water with a mixture of first-year ice, trace of old ice, young ice, and new ice along the Labrador coast. Frobisher Bay and Cumberland Sound contain a mixture of young and new ice. Eureka Sound and Jones Sound comprise fast first-year ice and some old ice. Davis Strait contains mostly first-year ice with some old ice. The Gulf of Boothia and southern Prince Regent Inlet contain first-year ice with a trace of old ice. Northern Prince Regent Inlet is fasted first-year ice with a trace of old ice.
The Arctic Ocean contains old ice. In Nares Strait, fast ice contains a mixture of old ice and first-year ice. South of the ice bridge in Smith Sound, there is a mixture of old ice, first-year ice, young ice, and new ice. Lancaster Sound contains mostly first-year ice with some old ice. Baffin Bay contains mostly first-year ice with some old ice. There is young ice and new ice in the southeastern section along the Greenland coast. Cumberland Sound comprises new, young and first-year ice in equal proportions.
The waters around the Queen Elizabeth Islands are fast old ice and first-year ice. M’Clure Strait and Viscount Melville Sound contain predominantly fast old ice with some first- year ice. Barrow Strait is fast first-year ice with some old ice in the western section; in the eastern section there is mobile first-year ice, young ice and new ice with a trace of old ice. M’Clintock Channel is fast first-year ice with a trace of old ice. Peel Sound is fast first-year ice with a trace of old ice. Victoria Strait is fast first-year ice. There is an area of mobile first-year ice in the southern section. Queen Maud Gulf and Coronation Gulf are fast first-year ice. Amundsen Gulf is mostly fast first-year ice with a trace of old ice in the northern section. Canada Basin is predominantly old ice with some first-year ice. The Beaufort Sea is predominantly first-year ice with some old ice.
James Bay contains first-year ice. Hudson Bay comprises first-year ice with young and new ice forming along the northwestern coast where the pack pulls away. Hudson Strait contains mostly first-year ice with young and new ice along parts of the coasts. Ungava Bay contains mostly first-year ice in the northern and eastern sections with young and new ice in the southwestern section where the pack pulls away from the coast. Foxe Basin contains mostly first-year ice with some young ice present in the western section along the coast.
Sea ice drifted counterclockwise this week, despite easterly winds (~27 knots) at the northern tip of Novaya Zemlya. These strong easterlies significantly affected the ice edge, notably disrupting the thinner ice. Katabatic winds contributed to small openings in the ice in coastal areas. A developing low pressure system brought warmer air temperatures across the northern Kara Sea, encouraging these openings. In the southern Kara Sea, average air temperatures around -27?°C supported rapid refreezing.
Sea ice continues to drift southward and extend off the Sakhalin Island toward Hokkaido, where it melts in warmer waters. The Shelikhov Gulf has seen a big change from a passing storm breaking apart and pushing the ice edge into the coastline; while conditions across the rest of the Sea of Okhotsk remain largely unchanged.
