Black Ice - Ice Formation On Seagoing Vessels

Ice Formation On Seagoing Vessels

Ice formation is a significant hazard for vessels operating in colder regions and it is caused by seawater spray and water vapour freezing into ice upon contact with the vessel's superstructure. Ice formed in this manner is known as 'rime'. As the formation of rime progresses, the weight of the vessel increases and may ultimately cause a capsizing moment to be created. Furthermore, rime ice may impede the correct functioning of important navigational instruments on board, such as radar or radio installations. Different strategies for the removal of such ice have been employed; chipping away the ice or even using fire hoses in an attempt to melt the ice away.

    “People in Stamps used to say that the whites in our town were so prejudiced that a Negro couldn’t buy vanilla ice cream. Except on July Fourth. Other days he had to be satisfied with chocolate.”
    —Maya Angelou (b. 1928)

    “The formation of an oppositional world view is necessary for feminist struggle. This means that the world we have most intimately known, the world in which we feel “safe” ... must be radically changed. Perhaps it is the knowledge that everyone must change, not just those we label enemies or oppressors, that has so far served to check our revolutionary impulses.”
    —Bell (c. 1955)

    “deep in the manhood his childhood
    so swiftly led to, a small brook rock-leaping
    into the rapt, imperious, seagoing river.”
    —Denise Levertov (b. 1923, Anglo–U.S. poet. “The Son.”

    “First, there is the power of the Wind, constantly exerted over the globe.... Here is an almost incalculable power at our disposal, yet how trifling the use we make of it! It only serves to turn a few mills, blow a few vessels across the ocean, and a few trivial ends besides. What a poor compliment do we pay to our indefatigable and energetic servant!”
    —Henry David Thoreau (1817–1862)
