In-Stream Reactivity of Dissolved Organic Matter and Nutrients in Proglacial Watersheds
… on in-stream metabolism and uptake potential of proglacial streams; 2) quantify changes in DOM composition and concentration in glacial runoff during precipitation-driven flushing of a glaciated landscape; and 3) characterize the impact of glacial landcover and meltwater contributions on …

SURFACE WATER – GROUNDWATER INTERACTIONS IN A PROGLACIAL ALPINE CATCHMENT: Applications of Heat Tracing, Modeling, and Remote Sensing Methods
… on stream water resources that originate in proglacial alpine catchments. The Cordillera Blanca, which is a mountain range in the Peruvian Andes, contains the highest density of tropical alpine glaciers worldwide, and the meltwater from these glaciers helps to sustain streamflow during the …

Quaternary geology and glacial history of the Haliburton region, south central Ontario, Canada: A model for glacial and proglacial sedimentation
… during active ice-margin retreat. The style of proglacial sedimentation suggests that topographically controlled subglacial drainage systems were the primary mechanism of sediment delivery to the ice-margin, and the prevalence of ice-contact terraces within these deposits indicates that …

Subsurface Geophysical Investigations of Oneida Lake Ny: Insights Into Ice Sheet Processes and Deglaciation At Termination I
… encourage ice stream development. In addition, proglacial lakes also form in topographic lows, and enhance calving processes and can accelerate deglaciation or serve as corridors of easy ice sheet readvance. The deepest section of a basin likely contains the most complete and highest resolution …

Glacier retreat and projected river regime changes in the hydrologically highly-coupled Virkisjökull catchment, SE Iceland
… 4 years includes measurement of ice ablation, proglacial discharge, dye-tracing of flow pathways, and deployment of three automatic weather stations at altitudes up to 880 m. These data calibrate a distributed hydrological model (WaSIM) to project potential river regime during stages of glacier …

Ice dynamics and glacial history from remote sensing of the Seno Skyring-Seno Otway-Strait of Magellan region, southernmost Patagonia
… was caused by calving into one of two ice-dammed proglacial lakes. The lakes were located within the former Seno Skyring and Seno Otway ice lobes, which are well-defined by arcuate sequences of moraine ridges. The westernmost of the lakes, proglacial Lake Skyring, is delimited by a series of …

The hydrology of debris-covered glaciers
… tracing and water chemistry monitoring; and the proglacial runoff was examined through detailed hydrograph analysis. Glacier velocity measurements were used to investigate the debris’ influence on the glacier dynamics. High ablation rates occurred on clean ice and beneath thin debris on the upper …

The Hydrological System of Storglaciären, Sweden: Integrating Modelling with Observations
… from moulins to the terminus to produce proglacial discharge. The surface-energy-balance model was validated using Storglaciären’s summer mass-balance data and measurements of surface lowering at an automatic weather station on its surface. It performed well, though slightly (~4%) …

Refining the span and rates of deposition of the Glenwood phase of Lake Chicago
The Glenwood phase of proglacial Lake Chicago is its oldest phase, but is the least studied. By developing the and ideas previously published maps by Bretz in the 1930s and studies by Hansel, Mickelson, Thompson and others I will be redefining the span and role of the Glenwood Phase of proglacial …

Modelling meltwater drainage in the Paakitsoq region, western Greenland, and its response to 21st century climate change
… CSAs. Comparisons between measured and modelled proglacial discharge suggest that the appropriate k factor (the ratio of water pressure to ice overburden pressure) for modelling the study system is between 0.925 and 0.95. The most extreme climate scenario predicts a ~7oC rise from 2010 to 2100, …

Late Quaternary Mississippi River Incised Valley Fill: Transgressive Depositional Packages
… River incised valley. Meltwater floods from proglacial lakes incised into older deposits followed by braided fluvial (substratum) aggradation due to reduced carrying capacity after floods followed by meandering fluvial(topstratum aggradation as fluvial gradients and discharge decreased. …

Drowned landscapes of the Belgian Continental Shelf : implications for northwest European landscape evolution and preservation potential for submerged heritage
… level movement occurs on a local/regional scale. Proglacial lakes in the North Sea Basin may have been a common landform during glacial periods. They were fed by meltwater from the Fennoscandian and British-Irish ice- sheets causing their levels to rise and exert major pressure on their confining …

The Hydrology of a Sandur-Wetland in a Volcanic Environment, Southeast Iceland
… in climate and geography. A 2.5 km stretch of a proglacial river neighboring an inhabited wetland was monitored between September 2015 to September 2016. Water wells along transects coupled with pressure transducers monitored the water table response across this sandur-wetland landscape. …

Surface water and groundwater in a changing climate: applications of hydrogeophysics and trend analysis to understand hydrologic systems
… <p>In the arid outer tropics of Peru, alpine proglacial valleys are storing groundwater that supplies a significant quantity of base flow to the regional surface water system. This is especially evident during the region’s dry season from May to October, during the Austral winter. The …
