Building Mesoarchaean crust upon Eoarchaean roots : the Akia Terrane, West Greenland
... Constraining the source, genesis, and evolution of Archaean felsic crust is key to understanding the growth and stabilization of cratons. The Akia Terrane, part of the North Atlantic Craton, West Greenland, ...

Ice-dammed lake drainage evolution at Russell Glacier, West Greenland
... Glaciological and hydraulic factors that control the timing and mechanisms of glacier lake outburst floods (GLOFs) remain poorly understood. This study used measurements of lake level at 15 min intervals and known lake ...

A decade (2002–2012) of supraglacial lake volume estimates across Russell Glacier, West Greenland
... Abstract. Supraglacial lakes represent an ephemeral storage buffer for meltwater runoff and lead to significant, yet short- lived, episodes of ice-flow acceleration by decanting large meltwater and energy fluxes into the ...

Ice-dammed lake and ice-margin evolution during the Holocene in the Kangerlussuaq area of west Greenland
... There is a lack of detailed information on the Holocene evolution of the west Greenland ice margin, not least because it was farther inland than at present and thus at present is covered by ice. Suggestions ...
