A model for interaction between conduits and surrounding hydraulically connected distributed drainage based on geomorphological evidence from Keewatin, Canada [PDF]
The Cryosphere, 2020 We identify and map visible traces of subglacial meltwater drainage around the former Keewatin Ice Divide, Canada, from high-resolution Arctic Digital Elevation Model (ArcticDEM) data.

The aftermath of Petermann Glacier calving events (2008-2012): Ice island size distributions and meltwater dispersal. [PDF]
, 2018 Three large calving events occurred at Petermann Glacier in northwest Greenland between 2008 and 2012 that generated ice islands (large tabular icebergs) that ranged from ~30 to 300 km2 in areal extent.

Glacial meltwater identification in the Amundsen Sea [PDF]
, 2017 Pine Island Ice Shelf, in the Amundsen Sea, is losing mass because of warm ocean waters melting the ice from below. Tracing meltwater pathways from ice shelves is important for identifying the regions most affected by the increased input of this water ...

Frontiers in Marine Science, 2019 Warming along the Antarctic Peninsula has led to an increase in the export of glacial meltwater to the coastal ocean. While observations to date suggest that this freshwater export acts as an important forcing on the marine ecosystem, the processes ...

Deep Underground Science and Engineering, EarlyView.Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Climate change in lowland Central America during the late deglacial and early Holocene [PDF]
The transition from arid glacial to moist early Holocene conditions represented a profound change in northern lowland Neotropical climate. Here we report a detailed record of changes in moisture availability during the latter part of this transition (11 ...

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique
Journal of Quaternary Science, EarlyView.ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Modelling sea-level observations to investigate the source and magnitude of major meltwater pulses during termination 1 [PDF]
, 2006 The research presented in this thesis utilises available near and far-field sea- level records to provide constraints on the major rapid sea-level rise events that occurred during the most recent period of deglaciation (Termination 1).The far-field ...

Groundwater - meltwater interaction in proglacial aquifers [PDF]
, 2019 Groundwater plays a significant role in glacial hydrology and can buffer changes to the timing and magnitude of meltwater flows. However, proglacial aquifer characteristics or groundwater dynamics in glacial catchments are rarely studied directly.
