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:
“They were evidently small men, all wind and quibbles, flinging out their chaffy grain to us with far less interest than a farm- wife feels as she scatters corn to her fowls.”
—D.H. (David Herbert)
“Destiny is an absolutely definite and inexorable ruler. Physical ability and moral determination count for nothing. It is impossible to perform the simplest act when the gods say “no.” I have no idea how they bring pressure to bear on such occasions; I only know that it is irresistible.”
—Aleister Crowley (1875–1947)
