“…Additionally, it is estimated that over the past decade, tides have been responsible for an approximately 15% reduction in the volume of Arctic sea ice [28]. Another study found that tidal forcing decreased ice volume by 17.8% in the Canadian Arctic Archipelago due to the suppression of ice formation in winter [29]. Tides generally have small amplitudes in the Arctic, but Kane Basin is an exception.…”

The North Water (NOW), situated between Ellesmere Island and Greenland in northern Baffin Bay, is the largest recurring polynya in the Canadian Arctic. Historically, the northern border of the NOW is defined by an ice arch that forms annually in Kane Basin, which is part of the Nares Strait system. In 2007 the NOW ice arch failed to consolidate for the first time since observations began in the 1950s. The non-formation of the NOW ice arch occurred again in 2009, 2010, 2017 and 2019. Satellite Advanced Very High Resolution Radiometry data shows that large floes broke off from the normally stable landfast ice in Kane Basin for each of these years, impeding ice arch formation. A closer analysis of a 2019 event, in which 2500 km2 of ice sheared away from Kane Basin, indicates that significant tidal forces played a role. The evidence suggests that thinning ice from a warming climate combined with large amplitude tides is a key factor in the changing ice dynamics of the NOW region. The non-formation of the NOW ice arch results in an increased loss of multiyear ice through Nares Strait.

“…Figure 1. Schematic diagram of key Straits in the Arctic Northeast Passage.The sea ice is the key factor influencing the navigation and utilization of the Arctic shipping routes, which is also influenced by various factors such as temperature, air pressure, wind fields, ocean currents, and surface runoff[6][7][8][9][10]. Thus, the significant variability in the annual melting and freezing of sea ice leads to substantial uncertainty in the navigational period of the Arctic shipping routes each year.…”

Landfast ice is one of the most important factors that affect the navigation safety of Arctic Northeast and Northwest Passages but usually is treated as drift ice in previous studies. This study focused on the situation of landfast ice in four key traits of the Arctic Northeast Passage from 2007 to 2021 and calculated the navigational windows for different ice-class vessels in the influence of landfast ice. The results show that the extent of landfast ice in these straits generally reaches its maximum from March to June, and decreases to a minimum or even disappears in July and August. The proportion of landfast ice extent in the four straits is quite different, such as Bering Strait (1.3%), De Long Strait (3.6%), Dmitry Laptev and Sannikov Strait (DLS Strait) (53.5%), and Vilkitsky Strait (27.8%). The average navigational windows range from 27 weeks (Bering Strait) to 8 weeks (Vilkitsky Strait) per year, and the Bering Strait showed the smallest increase trend (0.20 weeks per year), while the Vilkitsky Strait experienced the largest increase trend (0.62 weeks per year). The increasing navigational windows in the key straits are beneficial for future commercial and scientific expeditions of polar vessels in the Northeast Passage.
