Greenland Ice Sheet Response to Stratospheric Aerosol Injection Geoengineering

Earth's Future, 2019
The Greenland ice sheet is expected lose at least 90% of its current volume if ice sheet summer temperatures warm by around 1.8 °C above pre‐industrial. Geoengineering by stratospheric sulfate aerosol injection might slow Greenland ice sheet melting and ...

Lateglacial and Holocene glacier variations in an active volcanic area, northern Jan Mayen (Nord‐Jan), Norway

Boreas, EarlyView.
Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

Large-ensemble simulations of the North American and Greenland ice sheets at the Last Glacial Maximum with a coupled atmospheric general circulation–ice sheet model [PDF]

Climate of the Past
The Last Glacial Maximum (LGM) was characterised by huge ice sheets covering the Northern Hemisphere, especially over North America, and by its cold climate.

The role of inland ice dynamics in controlling the variable maximum extent of the Laurentide Ice Sheet off southeastern Baffin Island

Boreas, EarlyView.
Reconstructions of the maximum extent of the Laurentide Ice Sheet (LIS) and its associated ice flows at the Last Glacial Maximum (LGM) are needed for understanding how marine‐based ice sheets will respond to modern climate change. Here, we provide evidence for the location of the maximal extent of the LIS margin during the LGM in Merchants and ...

CMIP5 model selection for ISMIP6 ice sheet model forcing: Greenland and Antarctica

The Cryosphere, 2019
. The ice sheet model intercomparison project for CMIP6 (ISMIP6) effort brings together the ice sheet and climate modeling communities to gain understanding of the ice sheet contribution to sea level rise.

Relative sea‐level trends in southern Norway during the last millennium

Boreas, EarlyView.
Relative sea level in southern Norway has been falling since c. 7000 cal. yr BP, but modern tide gauge data show rising relative sea level since at least 1960 CE. In this study, peat cores from a shallow coastal basin were analysed, using a multiproxy approach, to reconstruct relative sea level trends over the last millennium and to identify the onset ...

Dark ice dynamics of the south-west Greenland Ice Sheet [PDF]

The Cryosphere, 2017
Abstract. Runoff from the Greenland Ice Sheet (GrIS) has increased in recent years due largely to declining albedo and enhanced surface melting. Some of the largest declines in GrIS albedo have occurred in the ablation zone of the south-west sector and are associated with the development of 'dark' ice surfaces. Field observations at local scales reveal

Complex past ice flow from Norway to the North Sea Plateau during the Quaternary: evidence from Marstein Trough and earlier reconstructions using 3D seismic data sets

Boreas, EarlyView.
We have mapped a 60 km long, 30 km wide, 120 m deep buried glacially eroded trough on the North Sea Plateau, west of the Norwegian Channel (59°N, 3°E). The trough was carved out by an ice stream that flowed out from western Norway and crossed the Norwegian Channel in a southwestern direction during the penultimate or Saalian glaciation.

Influence of temperature fluctuations on equilibrium
ice sheet volume [PDF]

The Cryosphere, 2018
Forecasting the future sea level relies on accurate modeling of the response of the Greenland and Antarctic ice sheets to changing temperatures. The surface mass balance (SMB) of the Greenland Ice Sheet (GrIS) has a nonlinear response to warming. Cold
