12. Aerial view of Phantom Lake with countles icebergs and Phantom Peak.

13. We'll be driving the herd up and down icebergs yet.

14. The average northern limit of icebergs is 45° south latitude.

15. The drift of the icebergs in the sea endangers the ships.

16. 12 Icebergs are notoriously unstable and are likely to turn over.

17. (The analogy of icebergs moving around a submerged sandbar is quite apt.)

18. Agate Fjord with many stranded icebergs from this glacier is even further left.

19. Snow petrels nest on the icebergs and feed on the sea life nearby.

20. Every one of these huge icebergs will slowly drift out to sea.

21. Every single one of these icebergs raises the sea level a small amount.

22. Icebergs from Iceberg Glacier have stranded in Agate Fjord (photo Melissa Battler 2008).

23. It was a bold antiphrasis that gave such a vernal title to this birthplace of icebergs.

24. That, along with icebergs, brings additional risks to successful oil and gas development and production.

25. Icebergs that last for a week or longer provide perches for bald eagles, cormorants and gulls.

26. Although they form in far northern or southern areas, icebergs can float thousands of miles.

27. Icebergs are created when chunks of pack ice break free and float off into open sea.

28. Glaciers such as Jakobshavn are calving icebergs much faster than scientific models had predicted they would.

29. Icebergs, many, many, many, many times the size of this building, are roaring out to sea.

30. Some icebergs are so unstable that they have more dramatic ends, heaving up, collapsing, and sometimes even exploding.

31. The film depicts Lightoller informing Captain Smith that it will be difficult to see icebergs without breaking water.

32. 20 Chinstrap penguins ride out high surf on blue - icebergs near Candlemas Island in the South Sandwich Islands.

33. Brinicle Brinicles are hazardous ice formations found descending from the undersides of icebergs in the East Arctic and Sparse Arctic

34. In general, the accumulation zone accounts for 60–70% of the glacier's surface area, more if the glacier calves icebergs.

35. Icebergs are scraping the sea floor of Antarctic waters more than ever, much to the detriment of bottom-dwelling creatures.

36. Yet, the Institute for Economic Research warned that these “are just tips of bankrupt icebergs floating in a vast sea of debt.”

37. Their colony is in the lee of icebergs trapped in the frozen ocean, which will shelter them from the bitter Antarctic winds.

38. In spring and early summer, the Labrador Current transports icebergs from the glaciers of Greenland southwards into the trans-Atlantic shipping lanes.

39. The lack of waves made it even more difficult to spot icebergs , since there was no telltale white water breaking at the edges of the bergs .

40. Though icebergs no longer dot the waters of Bartlett Cove, the animals, plants, and landscape continue to change after being affected by the Neoglacial Ice Age

41. The eye-watering entry on its website reads: "The forerunning Shtokman concept is a floating, disconnectable spar able to dodge roving icebergs of the 2m-tonne variety."

42. Above its heavy breathing, all you can hear in this wilderness is the drip-drip of melting ice and a crash as icebergs cleave into even smaller lumps, called growlers.

43. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalinization, or removing salt from water.

44. After icebergs are calved, the ocean current carries most of them on an extended journey before swinging some of them west and south and eventually into the Labrador Sea, nicknamed Iceberg Alley.

45. ‘A glaciologist said the Crevasses could be wide open, waiting to swallow the unwary.’ ‘The lake invades the glacier's deep chasms and Crevasses, detonating thunderous explosions as great shards of ice detach and re-emerge as icebergs.’

46. The exercise area abounded with icebergs and growlers, which required bridge watchkeepers to be constantly on the alert, particularly at night; the presence of large masses of ice also made it difficult for searching aircraft as they had to spend a large part of their time investigating false contacts.
