This cross-shelf glaciation is more pronounced during late Miocene and early Pliocene along Blosseville Kyst and around the Pliocene/Pleistocene boundary off Scoresby Sund; indicating a northward migration of the glacial advance.
The onset of cross-shelf glaciation on the western Canadian Beaufort Sea margin is inferred to have been initiated significantly later than on the eastern Beaufort Sea and eastern Canadian Arctic margins, which have a longer history of ice advance and were less peripheral to the ice-sheet centre.
The present study is the first to document the large-scale glacigenic evolution of a West Greenland trough-mouth fan (TMF) system, i.e. the Disko Bay TMF, from onset of shelf-based glaciation to present.
Although the imprint of extensive shelf-edge ice sheet glaciation exists in the coastal landscape of western Scotland, the dominant landscape features relate to a restricted, marine-proximal mountain ice sheet with markedly different flow configurations.
Potential mechanisms for the phylogenetic structure to Antarctic extinctions include continental isolation, changes in primary productivity leading to turnover of both predators and prey, and the effect of glaciation on shelf habitats.
Polar continental shelves in areas that escaped glaciation during the ice ages were exposed during periods of low sea level, especially in the Bering Strait and Sea (Beringia), which facilitated migration of people to North America from Asia, and in the Laptev and East Siberian seas.
Quaternary climatic and eustatic cycles in mid-latitude regions have led to more extensive alpine glaciations and continental shelf progradation, respectively.
During the Pleistocene glaciations, the continental shelf under the East China Sea emerged and provided land bridge connections between the southern Ryukyus Archipelago and the Asian continent [ 9, 10].
In the Southern Hemisphere, glacial deposits reflecting the Gondwanan continental glaciation were common, although shelf deposits of terrigenous clastics and even limestones were present in some areas.
In addition, the presence of glacial meltwater drainage on the shelf implies a greater volume of continental glaciation during the LGM than previously recognized.
However, field evidence supports extensive glaciation along the polar continental shelves and coastal Pacific lowlands (maximum model) [ 13].
