DOI: 10.1002/2016gl071645
Abstract: The discharge of icebergs into the polar oceans is expected to increase over the coming century, which raises the importance of accurate representations of icebergs in global climate models (GCMs) used for future projections. Here,… read more here.

Investigating the Direct Meltwater Effect in Terrestrial Oxygen‐Isotope Paleoclimate Records Using an Isotope‐Enabled Earth System Model
Sign Up to like & getrecommendations! Published in 2017 at "Geophysical Research Letters"
DOI: 10.1002/2017gl076253
Abstract: Variations in terrestrial oxygen-isotope reconstructions from ice cores and speleothems have been primarily attributed to climatic changes of surface air temperature, precipitation amount, or atmospheric circulation. Here we demonstrate with the fully coupled isotope-enabled Community… read more here.

Impact of glacial meltwater on spatiotemporal distribution of copepods and their grazing impact in Young Sound NE, Greenland
Sign Up to like & getrecommendations! Published in 2018 at "Limnology and Oceanography"
DOI: 10.1002/lno.10633
Abstract: The melting of sea ice, increased terrestrial runoff and meltwater from the Greenland Ice Sheet contribute to increased freshening and stratification of Arctic seas. However, the impacts on ecosystem structure and carbon cycling are still… read more here.

Surface meltwater drainage and ponding on Amery Ice Shelf, East Antarctica, 1973–2019
Sign Up to like & getrecommendations! Published in 2021 at "Journal of Glaciology"
DOI: 10.1017/jog.2021.46
Abstract: Abstract Surface melting on Amery Ice Shelf (AIS), East Antarctica, produces an extensive supraglacial drainage system consisting of hundreds of lakes connected by surface channels. This drainage system forms most summers on the southern portion… read more here.

Accumulation of pollutants in proglacial lake sediments: Impacts of glacial meltwater and anthropogenic activities.

DOI: 10.1021/acs.est.0c01849
Abstract: With global warming, melting of glaciers can result in release of pollutants into the environment. For remote Alpine lakes, both atmosphere-deposited anthropogenic pollutants and glacier-released pollutants can eventually sink in the sediment. To date, there… read more here.

Antarctic ice shelf potentially stabilized by export of meltwater in surface river
Sign Up to like & getrecommendations! Published in 2017 at "Nature"
DOI: 10.1038/nature22048
Abstract: Meltwater stored in ponds and crevasses can weaken and fracture ice shelves, triggering their rapid disintegration. This ice-shelf collapse results in an increased flux of ice from adjacent glaciers and ice streams, thereby raising sea… read more here.

Widespread movement of meltwater onto and across Antarctic ice shelves
Sign Up to like & getrecommendations! Published in 2017 at "Nature"
DOI: 10.1038/nature22049
Abstract: Surface meltwater drains across ice sheets, forming melt ponds that can trigger ice-shelf collapse, acceleration of grounded ice flow and increased sea-level rise. Numerical models of the Antarctic Ice Sheet that incorporate meltwater’s impact on… read more here.

DOI: 10.1073/pnas.2001697117
Abstract: Significance Glaciers are retreating rapidly due to climate change, and these changes are predicted to reduce biodiversity in mountain ecosystems through the loss of specialized meltwater species. However, direct observations of how glacier change affects… read more here.
