Page 280 - ... producing a loud grinding, or lengthened acute tremulous noise, accordingly as the degree of pressure was diminished or increased, until it had risen as high as the deck. After about two hours, the velocity was diminished to a state of rest ; and soon afterwards, the two sheets of ice receded from each other, nearly as rapidly as they before advanced.
Page 277 - ... that of fields in general. " Fields may sometimes have their origin in heavy close packs, which, being cemented together by the intervention of new ice, may become one solid mass. In this way, are produced such fields, as exhibit a rugged, hummocky surface.
Page 321 - ... 3. On approaching a pack, field, or other compact aggregation of ice, the phenomenon of the ice-blink is seen whenever the horizon is tolerably free from clouds, and in some cases even under a thick sky. The ice-blink consists in a stratum of a lucid whiteness, which appears in that part of the atmosphere next the horizon.

Page 299 - The place of their retreat, however, is regulated by various circumstances ; it may sometimes depend on the quality and quantity of food occurring, the disposition of the ice, or exemption from enemies. At one time, their favourite haunt is amidst the huge and extended masses of the field ice ; at another, in the open seas adjacent. Sometimes the majority of the whales inhabiting those seas, seem collected within a small and single circuit ; at others, they are scattered in various hordes, and numerous...
Page 279 - The weaker field is crushed with an awful noise; sometimes the destruction is mutual ; pieces of huge dimensions and weight are not unfrequently piled upon the top, to the height of twenty or thirty feet, while a proportionate quantity is depressed beneath.
