Understanding the geometry of ice ridge keels is essential to accurately predict ice loading on offshore structures. This study examines the 2-D morphologies of 52 first-year keels observed Feb. 23rd through 26th of 2007 in the Northumberland Strait. Although previous studies of first-year ice ridge keels around the world found strong correlations between keel width and keel depth, this study found no significant relationship between the properties of independent, first-year ice ridge keels in the Northumberland Strait. The first-year keels observed in the Northumberland Strait were generally wider than first-year keels of the same depth in other locations.
