Traverse Route from Pituffik to Warming Land, North Greenland Open
We examine the feasibility of an overland motorised traverse from Pituffik to Greenland’s oldest ice outcrop in Warming Land, North Greenland. We assess a 778 km overland traverse that departs Pituffik via the Nunatarssuaq Take-Off Ramp, w…

Modeled Greenland Ice Sheet evolution constrained by ice-core-derived Holocene elevation histories Open
During the Holocene, the Greenland Ice Sheet (GrIS) experienced substantial thinning, with some regions losing up to 600 m of ice. Ice sheet reconstructions, paleoclimatic records, and geological evidence indicate that, during the Last Gla…

 The impact of ice mélange dynamics on the calving of two major Greenland tidewater glaciers, Helheim and Nunatakassaap Sermia Open
Ice mélange, a mixture of icebergs and sea ice located in front of tidewater glaciers usually terminating in relatively narrow fjords, is believed to impact the calving dynamics of said glaciers through buttressing force and to alter …

Modelling the evolution of the Greenland ice sheet over glacial-interglacial cycles Open
The Greenland ice sheet (GrIS) formed more than 1 Ma ago and has evolved over many glacial-interglacial cycles. As it still adjusts to past changes, correctly capturing its present-day state is essential to accurately predict its future ev…

Investigating seasonal basal properties in Greenland through ice velocity inversion Open
Surface melt runoff at the margins of the Greenland Ice Sheet has long been linked to seasonal surface velocity changes caused by water lubricating the base of the ice sheet and enhancing basal sliding. The relationship between seasonal ru…

ApRES observations of ice fabric in Greenland: From a climatic transition in the North to a potential historical ice stream remnant in the South Open
The crystal orientation fabric (COF) of ice sheets, characterized as the net alignment of ice crystals, can contain a record of past ice sheet dynamics and potentially climatic conditions. In turn, the COF significantly influences ice visc…
