Geophysical Research LettersGlacier retreat is projected to drive major shifts in the hydrology of many high‐elevation and high‐latitude watersheds. In particular, future decreases in glacier runoff are hypothesized to reduce the stability of hydro‐biogeochemical export.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica
Frontiers in Earth Science, 2022 Subglacial meltwater drainage can enhance localized melting along grounding zones and beneath the ice shelves of marine-terminating glaciers. Efforts to constrain the evolution of subglacial hydrology and the resulting influence on ice stability in space

Journal of Glaciology, 2022 We present the first fully coupled 3D full-Stokes model of a tidewater glacier, incorporating ice flow, subglacial hydrology, plume-induced frontal melting and calving. We apply the model to Store Glacier (Sermeq Kujalleq) in west Greenland to simulate a

Implementation of a process-based catchment model in a poorly gauged, highly glacierized Himalayan headwater [PDF]
Hydrology and Earth System Sciences, 2007 The paper presents a catchment modeling approach for remote glacierized Himalayan catchments. The distributed catchment model TACD, which is widely based on the HBV model, was further developed for the application in highly glacierized catchments on a ...

Geological and glacial-hydrologic controls on chemical weathering in the subglacial environment
Annals of Glaciology, 2022 A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

Effects of undercutting and sliding on calving: a global approach applied to Kronebreen, Svalbard [PDF]
The Cryosphere, 2018 In this paper, we study the effects of basal friction, sub-aqueous undercutting and glacier geometry on the calving process by combining six different models in an offline-coupled workflow: a continuum–mechanical ice flow model (Elmer/Ice), a climatic

Quantification of seasonal and diurnal dynamics of subglacial channels using seismic observations on an Alpine glacier [PDF]
The Cryosphere, 2020 Water flowing below glaciers exerts a major control on glacier basal sliding. However, our knowledge of the physics of subglacial hydrology and its link with sliding is limited because of lacking observations. Here we use a 2-year-long dataset made of on-

Snow and glacier hydrology [PDF]
Eos, Transactions American Geophysical Union, 2001 The study of snow and ice is rich in both fundamental science and practical applications. Snow and Glacier Hydrology offers something for everyone, from resource practitioners in regions where water supply depends on seasonal snow pack or glaciers, to research scientists seeking to understand the role of the solid phase in the water cycle and climate ...

A semi-automated, GIS-based framework for the mapping of supraglacial hydrology
Journal of Glaciology, 2023 Supraglacial drainage networks play an integral role in both glacier dynamics and run-off timing, and mapping them provides insight into their role in glacial systems.
