Ice Strength During the Melt Season
An analysis has been made of the changes in the strength of first-year sea ice as it goes through the melt season. A comparison has been made between measured ice borehole strengths and flexural strengths calculated using the equation of Timco and O’Brien (1994). Both strengths show a dramatic decre...
