A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years [PDF]
, 2016 Climate models show that ice-sheet melt will dominate sea-level rise over the coming centuries, but our understanding of ice-sheet variations before the last interglacial 125,000 years ago remains fragmentary.

Greenland ice sheet contribution to sea level rise during the last interglacial period: a modelling study driven and constrained by ice core data [PDF]
Climate of the Past, 2013 As pointed out by the forth assessment report of the Intergovernmental Panel on Climate Change, IPCC-AR4 (Meehl et al., 2007), the contribution of the two major ice sheets, Antarctica and Greenland, to global sea level rise, is a subject of key ...

Circum-Greenland, ice-thickness measurements collected during PROMICE airborne surveys in 2007, 2011 and 2015 [PDF]
, 2018 The Greenland ice sheet has experienced an average mass loss of 142 ± 49 Gt/yr from 1992 to 2011 (Shepherd et al. 2012), making it a significant contributor to sea-level rise.

The Cryosphere, 2020 . Observations and models agree that the Greenland Ice Sheet (GrIS) surface mass balance (SMB) has decreased since the end of the 1990s due to an increase in meltwater runoff and that this trend will accelerate in the future. However, large uncertainties

Earliest Holocene south Greenland ice sheet retreat within its late Holocene extent [PDF]
, 2014 Early Holocene summer warmth drove dramatic Greenland ice sheet (GIS) retreat. Subsequent insolation-driven cooling caused GIS margin readvance to late Holocene maxima, from which ice margins are now retreating.

Large subglacial source of mercury from the southwestern margin of the Greenland Ice Sheet
Nature Geoscience, 2021 The Greenland Ice Sheet is currently not accounted for in Arctic mercury budgets, despite large and increasing annual runoff to the ocean and the socio-economic concerns of high mercury levels in Arctic organisms.

Constraining GRACE-derived cryosphere-attributed signal to irregularly shaped ice-covered areas [PDF]
The Cryosphere, 2013 We use a Monte Carlo approach to invert a spherical harmonic representation of cryosphere-attributed mass change in order to infer the most likely underlying mass changes within irregularly shaped ice-covered areas at nominal 26 km resolution.

The Cryosphere, 2019 . The subglacial environment of the Greenland Ice Sheet (GrIS) is poorly constrained both in its bulk properties, for example geology, the presence of sediment, and the presence of water, and interfacial conditions, such as roughness and bed rheology ...

Greenland Ice Sheet solid ice discharge from 1986 through March 2020
Earth System Science Data, 2020 . We present a 1986 through March 2020 estimate of Greenland Ice Sheet ice discharge. Our data include all discharging ice that flows faster than 100 m yr−1 and are generated through an automatic and adaptable method, as opposed to conventional ...

Recent deposition of 210Pb on the Greenland ice sheet: variations in space and time [PDF]
, 1990 Detailed 210Pb profiles were determined for four Chernobyl dated\u27 snowpits sampled during a wide-ranging survey of the Greenland ice sheet during the 1988 season.
