<p> The open water season of Radstock Bay is less than three months
long and varies considerably from year to year. The break-up and ablation
sequence of the bay is regular and systematic, commencing with a period of
snow melt and run off and continuing until the dramatic evacuation of the
ice. This evacuation is dependent on the ice coverage of Lancaster Sound.
The ice foot, a feature found often on arctic beaches was found to be
larger in areas of more shallow sloping beaches. A sediment size analysis
revealed a trend of diminuation of grain size from S. to N. reflecting
net sediment transport in that direction. The two major geomorphic events
of the 1971 open water, were two storms, both of which had winds from the
S.E. that generated 1.0 meter waves which moved sediment from S. to N. The
importance of a small pack of ice in the nearshore zone in inhibiting wave
action was noted during one of these events. The freeze-up sequence
progressed slowly after the advent of sub-freezing temperatures until the
temperature of the seawater reached its freezing point, whereupon the rapid
covering of the bay with ice ensued.</p> / Thesis / Master of Science (MSc)
