Late Quaternary ice-ocean interactions in central West Greenland
… knowledge of the interactions between the Greenland Ice Sheet and climate is critical to understanding the possible impacts of future global warming, including ice sheet contribution to global sea-level rise and perturbations to ocean circulation. Recent acceleration, thinning and retreat …

Structure, variability, and dynamics of the West Greenland Boundary Current System
… the subpolar gyre. This thesis characterizes theWest Greenland Boundary Current System near Cape Farewell across a range of spatio-temporal scales. The boundary current system is composed of three velocity cores: (1) the West Greenland Coastal Current (WGCC), transporting Greenland and Arctic …

Modelling the subglacial drainage system of Petermann Glacier, north-west Greenland
Studies suggest that much of the Greenland Ice Sheet is accelerating as temperatures increase. Increased temperatures can raise the pressure in the subglacial drainage system as meltwater input increases and the system fails to efficiently evacuate it. Some studies suggest that increased …

The seasonal and interannual variability of the West Greenland Current system in the Labrador Sea
… components of the boundary current, the surface West Greenland Current and the subsurface Irminger Current, have a strong seasonal cycle. In the spring both the West Greenland and Irminger Currents are colder and fresher than in the fall. However, the West Greenland Current is faster and thicker …

Application of Wavelet Analysis for Examining Climate and Meltwater Runoff in the Paakitsoq Region, West Greenland
Land-terminating areas of the Greenland ice sheet have experienced significant mass loss over the last two decades, and a feedback between surficial meltwater production, resultant basal lubrication and ice-sheet flow velocity during the summer ablation season has been suggested as an explanation. …

Fluctuations of the West Greenland Ice Sheet, independent ice caps and mountain glaciers during the twentieth century
The Greenland Ice Sheet contains enough water to raise global sea levels by ~7 metres, but predictions of the actual potential future contribution in a warming climate vary widely. These can be improved through a better understanding of how the whole ice sheet and its outlet glaciers have responded …

Inferring subglacial hydrology from investigations of supraglacial lake drainages and meltwater plumes at Store Glacier, West Greenland
The Greenland ice sheet has experienced a six-fold increase in ice loss during the last three decades, contributing significantly to global sea level rise. About 60% of the Greenland ice loss comes from dynamic ice loss from tidewater glaciers. Tidewater glaciers each have unique subglacial …

Geochemical investigation of Meso- to Neoarchean (3075–2800 Ma) supracrustal rocks in the Nuuk region, southern west Greenland
… Ma) greenstone belts, Nuuk region, southwestern Greenland. The new data are used to investigate postdepositional alteration, petrogenesis of volcanic rocks, provenance of sedimentary rocks, and geodynamic setting. The Mesoarchean Ivisaartoq belt underwent two stages of calc-silicate …

Marine-terminating outlet glacier response to hydrological mechanisms: A comparative study at Store Glestcher and Rink Isbrae, Uummannaq Bay, West Greenland
… of marine-terminating outlet glaciers on the Greenland Ice Sheet are of crucial importance with their principal role in draining the ice sheet. Much work has focused on determining the processes and mechanisms influencing their flow, with most focus on terminus processes, whilst little …

Intra- and Inter-Seasonal Variability of Supra-Glacial 1 Streams and Lakes over the West Greenland Ice Sheet 2 from High-Resolution Satellite Optical Data
<p>The Greenland ice sheet (GrIS) is one of the largest glacial ice masses on Earth, second only to the Antarctic ice sheet. The surface hydrology of the GrIS plays a crucial role on the surface energy and mass balance budgets of the ice sheet as a whole. Surface water, known as supra-glacial …

Stable Isotopes as Tracers for Freshwater Fluxes into the North Atlantic
… of historical oxygen isotope data from the East Greenland Current system with data presented here indicates that its freshwater isotope signature has not been temporally constant. Specifically, in 2005, there was a shift to a value ? 10 h heavier than the long-term mean, indicating a large …

Remote sensing of rapidly draining supraglacial lakes on the Greenland Ice Sheet
Supraglacial lakes in the ablation zone of the Greenland Ice Sheet (GrIS) often drain rapidly (in hours to days) by hydraulically-driven fracture (“hydrofracture”) in the summer. Hydrofracture can deliver large meltwater volumes to the ice-bed interface and open-up surface-to-bed connections, …

The Devil's in the Diversity: Divergent Parasite Faunas and their Impacts on Body Condition in Two Greenland Caribou Populations
… condition and fecundity in two populations of west Greenland caribou (Rangifer tarandus groenlandicus). Parasite diversity was described using fecal flotations and examinations of abomasa and small intestines. Anoplocephalidae, Nematodirinae and “Strongyle”-type eggs and Eimeria oocysts were …

UAV-based investigations into the hydrology and dynamics of the Greenland Ice Sheet
… input into the subglacial system of the Greenland Ice Sheet can force dynamic responses on a range of scales from hourly to interannual. Observations of the ice sheet dynamic response are commonly made either through ground-based Global Navigation Satellite System (GNSS) measurements, …
