The thick covering of sediment on the stagnant glacier helped to insulate the underlying ice, helping to preserve it and prolonging the time it took to melt. Scientists typically classify sea ice by stages of development that relate to both thickness and age. The Ned Leech measures 3.25 from end to end. However, since these parameters are difficult to evaluate and vary in different parts of the glacier, it is a very rough estimate.
