Surface mass balance modelling of the Juneau Icefield highlights the potential for rapid ice loss by the mid-21st century

Journal of Glaciology
Plateau icefields are large stores of fresh water, preconditioned to enhanced mass loss due to their gently sloping accumulation areas. Accurate modelling of their mass balance is therefore crucial for sea-level rise projections. Here, we use the COupled

Estimating Greenland surface melt is hampered by melt induced dampening of temperature variability

Journal of Glaciology, 2018
The positive degree-day (PDD) model provides a particularly simple approach to estimate surface melt from land ice based solely on air temperature. Here, we use a climate and snow pack simulation of the Greenland ice sheet (Modèle Atmosphérique Régional,

Reconstruction of Past Glacier Changes with an Ice-Flow Glacier Model: Proof of Concept and Validation

Frontiers in Earth Science, 2021
Estimations of global glacier mass changes over the course of the 20th century require automated initialization methods, allowing the reconstruction of past glacier states from limited information. In a previous study, we developed a method to initialize

High-resolution reconstruction of Polar Ural glacier mass balance for the last millennium [PDF]

Annals of Glaciology, 2005
AbstractOur ultimate objective is to study the mass-balance variations of Polar Ural glaciers during the last millennium. We use mass-balance data for two glaciers between 1957 and 1981, climate data obtained by instrumental observations during the 20th century, and tree-ring data compiled for the last 1000 years.

An 11-year record of mass balance of Brewster Glacier, New Zealand, determined using a geostatistical approach

Journal of Glaciology, 2017
Recognising the scarcity of glacier mass-balance data in the Southern Hemisphere, a mass-balance measurement programme was started at Brewster Glacier in the Southern Alps of New Zealand in 2004.

Independent measurement of the top quark mass and the light- and bottom-jet energy scales at hadron colliders [PDF]

, 2007
A method for the simultaneous determination of the energy scales for b-quark jets and light jets, the jet energy resolution, and the top quark mass at hadron colliders is presented.

Mass balance evolution of Martial Este Glacier, Tierra del Fuego (Argentina) for the period 1960–2099 [PDF]

, 2009
The Martial Este Glacier in southern Tierra del Fuego was studied in order to estimate the surface mass balance from 1960 until 2099. For this reason a degree-day model was calibrated.

Studying in vivo dynamics of xylem-transported 11CO2 using positron emission tomography [PDF]

, 2020
Respired CO2 in woody tissues can build up in the xylem and dissolve in the sap solution to be transported through the plant. From the sap, a fraction of the CO2 can either be radially diffuse to the atmosphere or be assimilated in chloroplasts present ...
