Missing sea level rise in southeastern Greenland during and since the Little Ice Age [PDF]

Climate of the Past, 2023
The Greenland Ice Sheet has been losing mass at an accelerating rate over the past 2 decades. Understanding ice mass and glacier changes during the preceding several hundred years prior to geodetic measurements is more difficult because evidence of past ...

Large and irreversible future decline of the Greenland ice sheet

The Cryosphere, 2020
. We have studied the evolution of the Greenland ice sheet under a range of constant climates typical of those projected for the end of the present century using a dynamical ice sheet model (Glimmer) coupled to an atmosphere general circulation model ...

Microbial nitrogen cycling on the Greenland Ice Sheet [PDF]

Biogeosciences, 2011
Abstract. Microbial nitrogen cycling was investigated along a 79 km transect into the Greenland Ice Sheet (GrIS) in early August 2010. The depletion of dissolved nitrate and production of ammonium (relative to icemelt) in cryoconite holes within 7.5 km of the ice sheet margin suggested microbial uptake and ammonification respectively. Nitrogen fixation

3.5-Year Monitoring of 225 GHz Opacity at the Summit of Greenland [PDF]

PASP, 129, 025001 (2017), 2016
We present the 3.5-yr monitoring results of 225 GHz opacity at the summit of the Greenland ice sheet (Greenland Summit Camp) at an altitude of 3200 m using a tipping radiometer. We chose this site as our submillimeter telescope (Greenland Telescope; GLT) site, because its location offers favorable baselines to existing submillimeter telescopes for ...

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 ...

Greenland bare-ice albedo from PROMICE automatic weather station measurements and Sentinel-3 satellite observations

GEUS Bulletin, 2021
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) provides surface meteorological and glaciological measurements from widespread on-ice automatic weather stations since mid-2007.

Ice sheets as a significant source of highly reactive nanoparticulate iron to the oceans [PDF]

, 2014
The Greenland and Antarctic Ice Sheets cover ~\n10% of global land surface, but are rarely considered as active components of the global iron cycle. The ocean waters around both ice sheets harbour highly productive coastal ecosystems, many of which are ...

The cryoconite ecosystem on the Greenland ice sheet [PDF]

Annals of Glaciology, 2010
AbstractThis paper presents an assessment of biological activity associated with ice surface debris (cryoconite) at the ice-sheet scale. Estimates of the mass distribution of cryoconite over the Greenland ice sheet (GIS) and the biological activity associated with it are presented and then coupled with a surface mass-balance model to estimate total ...

Greenland ice sheet mass balance assessed by PROMICE (1995–2015)

Geological Survey of Denmark and Greenland Bulletin, 2019
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has measured ice-sheet elevation and thickness via repeat airborne surveys circumscribing the ice sheet at an average elevation of 1708 ± 5 m (Sørensen et al. 2018).

NorthGreen: unlocking records from sea to land in Northeast Greenland [PDF]

Scientific Drilling
The increasing anthropogenic CO2 forcing of the climate system calls for a better understanding of how polar ice sheets may respond to accelerating global warming.
