In the winter of 2006/2007 both ice arches failed to form for the first time in recorded history, causing sea ice to remain mobile in Nares Strait year-round (Kwok et al., 2010; Vincent, 2019) (Fig. 2, Supplement Fig. S1).
Enjoy life with your wife, whom you love, all the days of this meaningless life that God has given you under the sun—all your meaningless days. For this is your lot in life and in your toilsome labor under the sun. Ecclesiastes 9:9 NIV
Historically, the formation of a northern and southern [ice] arch has been observed in Robeson Channel and Smith Sound, respectively (Fig. 1) (Vincent, 2019).
