An ice sheet covered the half of Eurasia, and almost all Northern America, winning year by year during hundred and ten millenniums. Finally, the ice sheet cracks, opens, streams and spreads in gigantic torrents. A giga-spring begins which is going to last more than a millenium. To resist ...
During an ice age, there are significant temperature differences between the equator and the poles, and temperatures at deep-sea levels have also been shown to drop. This allows for large glaciers (comparable to continents) to expand, covering much of the surface area of the planet. Since the...
Antarctica (77° 30′ S, 161° E), are now free of ice and are below the permanent snow line (Figs. 1 and 2). Present day precipitation is approximately 100 mm of snow per year; hence it is a desert region into which the Wright Upper Glacier can only intrude 8 km before ablation...
earth history has our world ever become a frozen planet. Tropical oases always persisted on land, ensuring the survival of a wide biota, and equatorial ocean temperatures never departed more than 2–3°C from those of today. Nevertheless, the periodic expansion of continental ice sheets has ...
A case is made for the stability of the East Antarctic Ice Sheet during Pliocene time from landscape development and surficial sediments in the Dry Valleys sector of the Transantarctic Mountains. The alternate hypothesis of Pliocene melt... M Yamane,Y Yokoyama,A Abe-Ouchi,... 被引量: 0发表...
7.11.4 The Little Age Response of Tidewater Glaciers and Ice Shelves, Antarctic Peninsula The Little Ice Age is an important ‘palaeoclimate’ episode defined originally as the last readvance of alpine glaciers in the European Alps (Grove, 2004). Defining this event in the Antarctic is difficult...
(English):Dendroglaciological and lichenometric techniques are used to establish the Little Ice Age (LIA) history of two glaciers (Colonel Foster and Septimus) in Strathcona Provincial Park, Vancouver Island, British Columbia. Our lichenometric investigations were preceded by the development of a loc...
Biographies from the Heroic Age of Antarctic exploration, 1898-1922. When the maps were mostly blank and lessons of how to survive and travel in a cold environment were learned the hard way. Antarctic Books Heroic Age Biographies Captain Scott ...
Climatic conditions of the Penultimate Ice Age are analyzed on the basis of isotopicgeochemical analyses of an ice core from the Vostok Antarctic research station. Data from the core, which includes material from as deep as 2546 m, permits the compilation of a chronology of glacial sediments ...
