Supraglacial streams and rivers

LH Pitcher, LC Smith - Annual Review of Earth and Planetary …, 2019 - annualreviews.org
Supraglacial meltwater channels that flow on the surfaces of glaciers, ice sheets, and ice
shelves connect ice surface climatology with subglacial processes, ice dynamics, and …

Increasing surface runoff from Greenland's firn areas

AJ Tedstone, H Machguth - Nature Climate Change, 2022 - nature.com
At high elevations of ice sheets, melting snow generally percolates and refreezes, so does
not contribute to the shrinking of the ice sheet. Here, we systematically map the runoff area …

Direct measurements of meltwater runoff on the Greenland ice sheet surface

LC Smith, K Yang, LH Pitcher… - Proceedings of the …, 2017 - National Acad Sciences
Meltwater runoff from the Greenland ice sheet surface influences surface mass balance
(SMB), ice dynamics, and global sea level rise, but is estimated with climate models and …

Supraglacial river forcing of subglacial water storage and diurnal ice sheet motion

LC Smith, LC Andrews, LH Pitcher… - Geophysical …, 2021 - Wiley Online Library
Surface melting impacts ice sheet sliding by supplying water to the bed, but subglacial
processes driving ice accelerations are complex. We examine linkages between surface …

Meltwater storage in low-density near-surface bare ice in the Greenland ice sheet ablation zone

MG Cooper, LC Smith, AK Rennermalm, C Miège… - The …, 2018 - tc.copernicus.org
We document the density and hydrologic properties of bare, ablating ice in a mid-elevation
(1215 m asl) supraglacial internally drained catchment in the Kangerlussuaq sector of the …

Storage and export of microbial biomass across the western Greenland Ice Sheet

TDL Irvine-Fynn, A Edwards, IT Stevens… - Nature …, 2021 - nature.com
Abstract The Greenland Ice Sheet harbours a wealth of microbial life, yet the total biomass
stored or exported from its surface to downstream environments is unconstrained. Here, we …

Surface meltwater runoff on the Greenland ice sheet estimated from remotely sensed supraglacial lake infilling rate

K Yang, LC Smith, X Fettweis, CJ Gleason, Y Lu… - Remote Sensing of …, 2019 - Elsevier
Surface runoff constitutes a large percentage of Greenland Ice Sheet (GrIS) mass loss at
present but is difficult to measure directly. This study provides a novel method to estimate …

Supraglacial rivers on the northwest Greenland Ice Sheet, Devon Ice Cap, and Barnes Ice Cap mapped using Sentinel-2 imagery

K Yang, LC Smith, A Sole, SJ Livingstone… - International Journal of …, 2019 - Elsevier
Supraglacial rivers set efficacy and time lags by which surface meltwater is routed to the
englacial, subglacial, and proglacial portions of ice masses. However, these hydrologic …

Seasonal evolution of supraglacial lakes and rivers on the southwest Greenland Ice Sheet

K Yang, LC Smith, MG Cooper, LH Pitcher… - Journal of …, 2021 - cambridge.org
Supraglacial lakes and rivers dominate the storage and transport of meltwater on the
southwest Greenland Ice Sheet (GrIS) surface. Despite functioning as interconnected …

[HTML][HTML] A new surface meltwater routing model for use on the Greenland Ice Sheet surface

K Yang, LC Smith, L Karlstrom, MG Cooper… - The …, 2018 - tc.copernicus.org
Large volumes of surface meltwater are routed through supraglacial internally drained
catchments (IDCs) on the Greenland Ice Sheet surface each summer. Because surface …
