Interest For Pressure Ridges
From an engineering perspective, there are three reasons why pressure ridges, recent or old, are a subject of investigation. Firstly, because the highest loads applied on offshore structures operating in cold oceans by drift ice are associated with these features. Secondly, when pressure ridges drift into shallower areas, their keel may come into contact, thereby representing a risk for subsea pipelines (see Seabed gouging by ice). Thirdly, they have a significant impact on navigation. In the Arctic, ridged ice makes up about 40% of the overall mass of sea ice.

Famous quotes containing the words interest and/or pressure:
“Parents do not give up their children to strangers lightly. They wait in uncertain anticipation for an expression of awareness and interest in their children that is as genuine as their own. They are subject to ambivalent feelings of trust and competitiveness toward a teacher their child loves and to feelings of resentment and anger when their child suffers at her hands. They place high hopes in their children and struggle with themselves to cope with their children’s failures.”
—Dorothy H. Cohen (20th century)
“The area [of toilet training] is one where a child really does possess the power to defy. Strong pressure leads to a powerful struggle. The issue then is not toilet training but who holds the reins—mother or child? And the child has most of the ammunition!”
—Dorothy Corkville Briggs (20th century)
