Lateglacial and Holocene mountain glacier fluctuations near Cape Farewell South Greenland inferred from 10Be moraine dating

Journal of Quaternary Science, EarlyView.
ABSTRACT We report 43 new 10Be exposure ages and six 26Al/10Be measurements from replicates from a small piedmont mountain glacier located at Cape Farewell (south Greenland) and temperature anomalies estimated from equilibrium‐line altitude (ELA) changes derived from 3D glacier reconstruction carried out using the ‘GlaRe’ toolbox.

Chemical proxies of glacier‐derived and marine organic matter reveal low mixing in summer‐stratified Arctic fjords

Limnology and Oceanography, EarlyView.
Abstract The rapid deglaciation of the Arctic increases the flux of terrestrial organic matter into the marine carbon cycle. The proportions, mixing, and turnover rates of organic matter from deglaciated terrestrial and glacial watershed sources are poorly understood in Arctic fjords.

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 ...

Environmental controls of autotrophic biofilm biomass and community composition in subarctic lakes and streams in Greenland

Limnology and Oceanography, EarlyView.
Abstract Photosynthetic biofilms are key components of Arctic freshwater ecosystems, supporting primary production and forming the base of aquatic food webs. While several environmental factors regulating biofilms are known, their relative importance and connection to catchment characteristics across different Arctic ecosystems remain unclear.

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.

Greenland Ice Sheet surface melt amplified by snowline migration and bare ice exposure

Science Advances, 2019
Greenland’s snowline exhibits large fluctuations and is a primary amplifier of ice sheet surface melt and runoff. Greenland Ice Sheet mass loss has recently increased because of enhanced surface melt and runoff.

Glacial meltwater drives high CH4 supersaturation in Maxwell Bay, King George Island (Southern Ocean)

Limnology and Oceanography Letters, EarlyView.
Abstract Coastal waters exhibit the highest and most dynamic dissolved CH4 concentrations in marine environments, but significant knowledge gaps on the distribution and emissions, particularly in the Southern Ocean, still exist. We quantified dissolved CH4 concentrations and sea–air fluxes in the coastal waters of Maxwell Bay, King George Island ...

Holocene thinning in central Greenland controlled by the Northeast Greenland Ice Stream

Nature Communications
Ice-core records from the interior of the Greenland ice sheet suggest widespread thinning during the Holocene. However, the recurring underestimation of this thinning in numerical models raises concerns about both the veracity of such reconstructions and
