... 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...

... . Glomulina oculus n. sp. was first noted in modern and Holocene seafloor sediments sampled during the 2015 Petermann Glacier Expedition to northern Nares Strait and the Petermann Fjord, NW Greenland. The species was noted routinely during shipboard scanning for foraminiferal content in sediment cores during...

Geographically, cDML can be subdivided into ice shelves in the north, an ice slope in the middle, where the glacier surface ascends from almost zero to almost...

... on the non-magnetic minerals. In this review, we emphasize the magnetic minerals, which could be of either exogenetic or authigenic origin. The exogenetic components are in the form of detrital particles, which are mainly transported by wind, river and glacier into the ocean (Henshaw & Merrill, 1980...
