An Analysis Of Ice Profiles Obtained By Submarine Sonar In The Beaufort Sea

Abstract: ABSTRACT. A profile of the ice cover in the southern Beaufort Sea was obtained by the submarine U.S.S. Gurnard in April 1976, using a narrow-beam upward-looking sonar. The I 400 km profile consisted of three legs, of which the long south-north and east-west legs intersected near the Caribou camp of the AIDJEX experiment. A statistical analysis was carried out over contiguous 50 km sections to yield probability-density functions of the drafts of ice and of level ice, the distributions of keel spacings and draft… Show more

“…Temporal parameters 2.3.1. Ice ridge identification criterion Ridges were identified using the Rayleigh criterion with a threshold value of 2.5 m and a minimum draft of 5 m Wadhams and Horne (1980). This choice was done to be in line with previous work such as those of Melling and Riedel (1996), Wadhams and Davis (2000), and Wadhams et al (2011).…”

“…Narrow leads, tens to hundreds of meters wide, and often hundreds of kilometers long, are the predominant site of open water and young ice within the winter Arctic ice pack. Rapid thermodynamic growth of thinner ice maintains a low fraction of open water cover throughout the winter [ Wadhams and Horne , 1980]. Maykut [1978] states that leads represent about 1% of the sea ice pack.…”

“…On the basis of the observations of Ruffieux et al (1995) and Pinto et al (2003), one can estimate that a large lead (width of about 500 m) opening up directly upwind of an ice station can cause an increase of roughly 0.5 to 2 K in T 2 m (the exact value depending on several factors). Further, the opening up of a lead as wide as 500 m just upwind of an ice station in the central Arctic is a rare event [see Wadhams and Horne (1981) for lead statistics].…”
