Exempel på hur man kan använda ICEBERGS i en mening

• Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs.
• Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean.
• During the expedition of the Fram, Fridtjof Nansen had observed that icebergs tend to drift not in the direction of the prevailing wind but at an angle of 20°-40° to the right.
• A similar-sized calving in May 2000 created an iceberg 167 by 32 km in extent, dubbed A-43 – the disintegration of this is thought to have been responsible for the November 2006 sighting of several large icebergs from the coast of the South Island of New Zealand, the first time since 1931 that any icebergs had been observed from the New Zealand mainland.
• A few icebergs were sighted, but there was still no sight of land, leading Weddell to theorize that the sea continued as far as the South Pole.
• Where the glacier meets the bay, most of the ice is below the waterline, and newly calved icebergs can shoot up quite dramatically, so that ships must keep their distance from the edge of the glacier in Disenchantment Bay.
• In the summertime, the 71-foot tugboat escorts fuel tankers and cargo ships, aligns them with the pier, and moves icebergs out of the way as vessels enter North Star Bay.
• Ever since the loss of the RMS Titanic highlighted the dangers of icebergs in the North Atlantic, an International Ice Patrol has also originated weather data, and its charts are broadcast by the Boston station during the prime iceberg season of February through September, using the call sign NIK.
• When the Bedford detects a Soviet submarine just off the coast of Greenland, Finlander mercilessly stalks his prey into international waters and plays a waiting game after losing sonar contact in a field of icebergs, knowing the diesel-powered sub will have to surface within 24 hours to replenish its air and recharge its batteries.
• This contributed to his postulation that there had been a major Precambrian ice-age, with ice sheets or floating icebergs carrying the erratic blocks now embedded in the tillite, extending over most or all of the globe.
• The principal difficulty is that icebergs may fill the channel, especially in early season, obliging a ship to backtrack and go around the outside of Booth Island to reach Petermann.
• Frequently clogged by pack ice, particularly tabular icebergs broken from the Larsen Ice Shelf, it is deceptive and difficult to traverse, and in the year after its first navigation, the same vessel was trapped and crushed by the ice, the ship's crew spending the winter at Hope Bay.
• Iceberg impacts with the seafloor or other icebergs can also generate distinct iceberg harmonic tremor signals that propagate to large distances as ocean acoustic and solid Earth seismic wavefields.
• Calved from the Ross Ice Shelf of Antarctica in March 2000, Iceberg B-15 broke up into smaller icebergs, the largest of which was named Iceberg B-15-A.
• It appears Charles Darwin speculated in 1855 about the possibility that icebergs could gouge the seabed as they drifted across isobaths.
• Lightoller blamed the accident on the seas being the calmest that night that he had ever seen in his life and on the floating icebergs giving no tell-tale early-warning signs of breaking white water at their bases.
• Geikie became the leader of the school that upholds the all-important action of land-ice, as against those geologists who assign chief importance to the work of pack ice and icebergs.
• The flow of icebergs from the calved glacier tongue has reduced the effectiveness of the polynya west of Mertz Glacier that acted as one of Antarctica's major areas for the formation of dense Antarctic Bottom Water.
• The clay layers include incongruous cobbles and boulders, dropstones which melted free from icebergs floating above.
• Calving, in which ice detaches from the snout of a glacier that terminates in water, forming icebergs, is a significant form of ablation for many glaciers.
