Location of the mooring site in Lancaster Sound
These are plots of the point measurements from each mooring showing there are periods when the variability in the draft is very low, likely indicating the ice is nearly stationary (click on the image to see a blow-up).
Box plots for each of the mooring sites show the median (black) and the 5th, 25th, 75th, and 95th percentile values for each month. The colors show the month of the year.
