Sea Ice and Icebergs
Fjords and open sea around Axel Heiberg Island show a great variety of phenomena related to sea ice. Some spectacular icebergs also occur. However, these are not particularly abundant as Iceberg Glacier is the only glacier which calves a significant number of them at the present time.
Last winter's sea ice is breaking up in Norwegian Bay, south of Axel Heiberg (July 1, 2008).
Open water, loose floes of sea ice and pack ice in Norwegian Bay (July 1, 2008).
Ice floes of various ages (one, two or more years) and turquoise meltwater ponds (Norwegian Bay, July 1, 2008).
Older ice floe surrounded by one year old sea ice in Nansen Sound (1976).
Der Strand Fjord is still mostly ice-covered on July 1, 2008. Some open water is visible at the end of the fjord.
A big iceberg (also visible in the previous photo) affects the drainage pattern of the surrounding sea ice (July 1, 2008).
Photogenic pattern of melting sea ice in Expedition Fjord (July 3rd, 2008).
Chaotic arrangement of ice floes and prominent delta in a small, unnamend inlet in southern Axel Heiberg (August 24th, 1977).
A linear crack in the sea ice of Expedition Fjord (July 3rd, 2008).
Remarkable patterns formed by cracks in the sea ice, Expedition Fjord (July 3rd, 2008).
Radiation and runoff from the warm ground causes the sea ice to first disappear along the coast (July 3rd, 2008).
Raised beaches and a river delta on the north coast of Cornwallis Island (July 1, 2008).
Ice push along the shoreline of Index Finger Diapir Island has caused ridges in the beach gravel (July 2nd, 2008). Drageon Head Mountain in the background.
Ice floes were pushed several meters inland during the previous winter. A log, possibly originating in northern Siberia, was deposited (July 2nd, 2008).
Ice push (big gravel rideg on the right) and strand lines caused by the modest tides in Expedition Fjord (Index Finger Diapir Island, July 2nd, 2008).
During a moment of calm, the mountains south of Expedition Fjord form mirror images while the remaining sea ice quietly melts away (Index Finger Diapir Island, July 2nd, 2008).
An air temperature inversion causes mirages over the sea ice of Expedition Fjord. The icebergs appear much taller than they are due to the optical effect (July 3rd, 2008).
This isolated iceberg in Expedition Fjord carries a sign of "civilization": an abandond oil drum is lodged on its left side (July 3rd, 2008).
Icebergs from Iceberg Glacier in Expedition Fjord contrast with the tilted, dark volcanic rocks in the background (July 3rd, 2008).
Climbing an iceberg is not always easy, particularly without crampons (Expedition Fjord, spring 1976).
