Societal Adaptation to Climate Variability and Change by Sally M. Kane, Gary W. Yohe PDF

Adjustments in weather and weather variability affect people's behaviour worldwide, and public associations have a tremendous half to play in influencing our skill to reply to and plan for weather hazard. We are able to lessen weather threat through trying to mitigate the hazard at the one hand, and by means of adapting to a replaced weather at the different.

In smooth water the frazil stage passes relatively quickly via nilas into a consolidated sheet, from which brine drains as it grows thicker (Cox and Weeks, 1974). The subsequent development of the shorefast ice zone on a gently sloping shoreline has been reviewed by Kovacs and Mellor (1974) and Reimnitz et al. (1977) for the case of the Beaufort Sea. Comparable zones in Greenland and Svalbard have not been directly studied. Subsequent growth of shorefast ice depends on the shape of the shoreline, the bathymetry, and the motion of the offshore pack.

Milne (personal communication) has reported encountering a floe 10 to 12 m thick during an icebreaker voyage west of Prince Patrick Island in 1965, and there are a small number of other anecdotal reports. But it is clear that such floes are rare in the drifting pack. ittle more than 3 m, which is in reasonable accord with observations. Therefore we must look elsewhere for the origin of floes of exceptional thickness, and the natural conclusion is that they are formed as fast ice and represent the result of many years of growth in place before a final breakout into the pack.
