Temporal and Spatial Evolution of Hudson Bay Sea Ice (1971-2011)
Previous work has found Hudson Bay seasonal sea ice particularly sensitive to climate change with a strong signal of earlier breakup dates.

| Summary: | Previous work has found Hudson Bay seasonal sea ice particularly sensitive to climate change with a strong signal of earlier breakup dates. This work extends the analysis to include eight more years of sea ice data spanning 1971 to 2011. In addition, a spatial analysis using a grid of 36 locations in the Bay was done. The expanded sea ice record revealed stronger and more statistically significant trends than the earlier work, largely due to the accelerated temperature increase observed over the last decade, especially notable with later freeze-up dates. The spatial analysis was done using clustering statistics. Clusters of sea ice data points were found to be consistent with observed patterns of sea ice breakup and freeze-up. Clustering along the coasts for all three metrics had the greatest coherency suggesting that the shoreline provides a constraint that enables the ice within to act in a coherent fashion. M.Sc. |
