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.
Slight movement in the pack ice since the previous analysis generally to the west and southwest. New and young ice growth along the pack ice has extended south approximately 40NM in the Barents Northwest, and up to 90NM in the Barents Northeast. Fast ice within Franz Josef Land has expanded in coverage. New and young ice has begun forming along the coastal areas of Svalbard.
Davis Strait has young and new ice as far south as 63N past the mouth of Cumberland Sound. Cumberland Sound has new ice forming along the western shore and Frobisher Bay has new ice forming at the head of the bay and around Blunt Peninsula. Labrador Sea consists of bergy water with some patches of new ice formation in bays and inlets. Lake Melville has some areas of new and young ice formation.
The Arctic Ocean consists of multi-year ice. Nares Strait contains predominantly multi-year ice with young ice between the floes. Eastern Kane Basin contains predominantly young ice with some first-year ice and some multi-year ice. The ice in the Queen Elizabeth Islands is fast. It is predominately multi-year ice with some first-year ice and a little second-year ice near Devon Island. The ice in Nansen Sound, Eureka Sound and Greely Fiord is fast. The area contains mostly first-year ice with some multi-year ice. Jones Sound contains some multi-year ice with a mix of first-year and grey-white ice. It has become fast in about half of the sound. In Wellington channel, Barrow Strait and the northern part of Prince Regent Sound contain predominantly first-year ice with a trace to 1/10 of multi-year. The ice in Lancaster Sound and just east of Devon Island in Baffin Bay consists of a mixture of multi-year, predominantly first-year ice with a trace of second-year. Grey ice with some grey-white and new ice covers the rest of western Baffin Bay as well as the northwestern coast of Greenland and the western part of Davis Strait. Bergy water covers Cumberland Sound and the eastern parts of Baffin Bay and Davis Strait. Predominantly grey-white ice covers the Gulf of Boothia and Committee Bay as well as Fury and Hecla Strait. New and grey ice continues to develop in Foxe Basin and Roes Welcome Sound.
Ice around the Queen Elizabeth Islands consists of mostly fast multi-year ice mixed with lower amounts of second-year ice and first-year ice. The western part of Parry Channel now contains mostly grey-white and first-year ice with some multi-year ice. M’Clintock Channel is covered with a mix of first-year and grey-white ice with a trace of multi-year ice in the northern section. South of King William Island in the Rasmusen Basin and Storis Passage the ice is now fast with thin first-year ice with a little bit of grey-white ice. Peel Sound is fast with first-year ice. Larsen Sound is covered with mostly thin first-year ice and a few area with grey-white ice including a trace of multi-year ice in Victoria Strait area. Grey-white and grey ice is in western Queen Maud and Rae Strait. Coronation Gulf has a mix of grey-white, grey and new ice. Amundsen Gulf filled with grey-white and grey ice with a trace of multi-year ice in the northern section, along the southern coast of Banks Island. Along the Alaskan, Yukon and NWT coast from Point Barrow to Cape Bathurst has grey-white, grey and new ice. The leading edge of multi-year ice includes smaller amounts of second-year, first-year and grey-white ice and is located about 120 NM north of the coast.
The flow in the western part of the region is bringing in freezing waters from Siberia, generating rapid ice formation along the west and southern part of the region. Conversely, warming waters are moving northward in the eastern part of the region. This warming has caused large ice formation to be slightly slower than expected for this time of year.
With winter approaching, cold temperatures support the southward drift of mixed multi-year and first-year ice floes. Sea ice is now found along the Greenland coast 175NM south of Scoresby Sound. Fast ice coverage continues to expand in coastal regions and the ice pack continues to develop and consolidate.
Hudson Bay has young and new ice along all of the western shore and new ice has started forming along the eastern shore. Fast ice is present in northwestern sections. Southern Foxe Basin consists of young and new ice with some areas of open water and bergy water between Foxe and Bell Peninsulas. Most of Southampton Island is surrounded by young and new ice except for the western shore. Hudson Strait and Ungava Bay are mostly bergy water with some young and new ice forming along southern shorelines.
Ice has developed in the Tartar Strait around 08NOV and became 80-100% ice covered by 14NOV with new and young ice. Ice also started forming along the Russian coast. Ice in the Northern Shelikhov Gulf has thickened to first year ice in the northern most tip where ice has been present for a few weeks now.
