Modelling snow accumulation on Greenland in Eemian, glacial inception, and modern climates in a GCM [PDF]

, 2012
Changing climate conditions on Greenland influence the snow accumulation rate and surface mass balance (SMB) on the ice sheet and, ultimately, its shape.

The Influence of Hydrology on the Dynamics of Land-Terminating Sectors of the Greenland Ice Sheet

Frontiers in Earth Science, 2019
Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is a critical component of the Greenland Ice Sheet system. Despite considerable research effort, the mechanisms by which runoff influences ice dynamics and the net ...

Basal ice microbiology at the margin of the Greenland ice sheet [PDF]

Annals of Glaciology, 2010
AbstractBasal ice at the margin of the Greenland ice sheet was studied with respect to its physical characteristics and microbiological community. The basal ice contained high concentrations of dissolved ferrous Fe and must therefore be anoxic. Oxygen consumption experiments indicate that 50% of the oxidation was due to biological activity while the ...

The role of shallow banks and marine ice domes in marine‐based ice‐sheet deglaciation

Boreas, EarlyView.
Marine‐based ice sheets are susceptible to collapse and faster retreat than their land‐terminating counterparts. One of the key factors contributing to the relative stability of marine‐terminating ice sheets is the presence of shallow bathymetric banks and islands acting as pinning points for the ice sheet.

A summer time series of particulate carbon in the air and snow at Summit, Greenland [PDF]

, 2007
Carbonaceous particulate matter is ubiquitous in the lower atmosphere, produced by natural and anthropogenic sources and transported to distant regions, including the pristine and climate-sensitive Greenland Ice Sheet.

On the recent contribution of the Greenland ice sheet to sea level change

, 2016
. We assess the recent contribution of the Greenland ice sheet (GrIS) to sea level change. We use the mass budget method, which quantifies ice sheet mass balance (MB) as the difference between surface mass balance (SMB) and solid ice discharge across the

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

Boreas, EarlyView.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.

Persistence and dynamic of forest snails in the Western Carpathians over the last 40 thousand years

Boreas, EarlyView.
The glacial/interglacial cycles have shaped the landscape of temperate Europe for the past 2.5 million years, with open landscapes prevailing during the glacial and forested landscapes during the interglacial periods. However, the survival and recolonization strategies of temperate forest species during glacial phases remain poorly understood and hotly

Impact of ocean stratification on submarine melting of a major Greenland outlet glacier [PDF]

, 2011
Submarine melting is an important balance term for tidewater glaciers1,2 and recent observations point to a change in the submarine melt rate as a potential trigger for the widespread acceleration of outlet glaciers in Greenland3-5.
