... inception. The largest of these canyons terminates in northwest Greenland at the outlet of the Petermann Glacier. Yet, the genesis of this canyon, and similar features in northern Greenland, remains unknown. Here, we present numerical model simulations of early GrIS history and show that interactions among...

... the gold-coated specimens were photographed using a Versa 3D FIB-SEM at the iNANO Cryo-Electron Microscopy Facility. During the Petermann Glacier Expedition of Swedish Icebreaker Oden in 2015, the uppermost 1 to 2 cm of seafloor sediments were collected for foraminiferal analysis from 12 multicores...

... networks. This configuration is comparable with other paleofluvial landscapes identified beneath the Greenland Ice Sheet, including a mega-canyon that drains into the neighboring Petermann Glacier ( Bamber et al., 2013 ) and the Jakobshavn Isbræ drainage catchment in southwestern Greenland ( Cooper et al...

... ice tongues that extend beyond the coastline into the open ocean seem to be a feature of Antarctica in the present climate (the ice tongues of Greenland’s Petermann and Zachariæ Isstrøm glaciers are in protected fjords or bays). The tongues thin with distance from the grounding zone (the region where...

... inland from the coast; the ‘kryokonit’ had to be considered a loess deposit, wind blown silt from the dried up till and alluvial plains deposited by the streams in front of the coastal glaciers. Nordenskiöld, quarreling with von Richthofen’s almost universally accepted explanation of the loess...

...Lewis A. Owen; Robert C. Finkel; Marc W. Caffee; Lyn Gualtieri Abstract Moraines and associated landforms in the upper Hunza Valley, Karakoram Mountains, northern Pakistan, provide an excellent record of multiple glaciations. During the late Quaternary, glaciers advanced at least eight times...

There we found the same Silurian Rocks, and our explorers up Petermann Fiord ditto. Crossing over to Discovery Bay...

... Glacier, with an age of ∼4783 yr BP, and compared it with the surface pollen assemblages. The abundance of Pinus pollen (average 51.28% pollen) in the fossil pollen assemblage is comparable with the surface data (62.90%).

... and, though valid in principle, his method, utilizing the different travel-times for the two kinds of waves, could not be applied immediately. Studying the Visp Earthquake (1855), Georg Volger (with August Petermann) drew two isoseismal maps and proposed a numerical intensity scale, but it was not generally...

... Formation (Chapeu do Sol, Rio Segredo, and Rio do Sul members). Log correlation shows that most of the Itararé Group deposits represent a single major glacial advance during the deposition of the cycle. This glacier deposited tillites and glacial debris flows in a shallow sea in association with deltaic...

In contrast to the older moraines, Qm 2 moraines are characterized by innumerable water-filled kettle holes. Both groups of tills were deposited by piedmont glaciers that extended >10...

Willis and Schuchert agreed that bathymetric data should be used to determine where the land bridges might have been. The job of placing the bridges went to Willis.
