Geodetic point surface mass balances: a new approach to determine point surface mass balances on glaciers from remote sensing measurements [PDF]
The Cryosphere, 2021 Mass balance observations are very useful to assess climate change in different regions of the world. As opposed to glacier-wide mass balances which are influenced by the dynamic response of each glacier, point mass balances provide a direct climatic ...

A high-frequency, long-term data set of hydrology and sediment yield: the alpine badland catchments of Draix-Bléone Observatory [PDF]
Earth System Science Data, 2023 Draix-Bléone critical zone observatory was created in 1983 to study erosion processes in a mountainous badland region of the French Southern Alps. Six catchments of varying size (0.001 to 22 km2) and vegetation cover are equipped to measure water and ...

Strong changes in englacial temperatures despite insignificant changes in ice thickness at Dôme du Goûter glacier (Mont Blanc area) [PDF]
The Cryosphere, 2020 The response of very-high-elevation glaciated areas on Mont Blanc to climate change has been analysed using observations and numerical modelling over the last 2 decades. Unlike the changes at low elevations, we observe very low glacier thickness changes,

Ensemble quantification of short-term predictability of the ocean dynamics at a kilometric-scale resolution: a Western Mediterranean test case [PDF]
Ocean Science, 2022 We investigate the predictability properties of the ocean dynamics using an ensemble of short-term numerical regional ocean simulations forced by prescribed atmospheric conditions.

MobRISK: a model for assessing the exposure of road users to flash flood events [PDF]
Natural Hazards and Earth System Sciences, 2017 Recent flash flood impact studies highlight that road networks are often disrupted due to adverse weather and flash flood events. Road users are thus particularly exposed to road flooding during their daily mobility. Previous exposure studies, however,

Wintertime Supraglacial Lake Drainage Cascade Triggers Large‐Scale Ice Flow Response in Greenland
Geophysical Research Letters, 2023 Surface melt forces summertime ice‐flow accelerations on glaciers and ice sheets. Here, we show that large meltwater‐forced accelerations also occur during wintertime in Greenland.

Volume, Peak discharges and Froude Number of Debris-Flow Surges: 10 Years of Monitoring on the Réal Torrent (France) [PDF]
E3S Web of Conferences, 2023 This work presents a summary of data on debris-flow monitoring stations focusing on the surge scale rather than full-scale debris-flow event (several fronts and surges with intermediate diluted flows).

Wide-Swath Altimetric Satellite Data Assimilation With Correlated-Error Reduction
Frontiers in Marine Science, 2020 For decades now, satellite altimetric observations have been successfully integrated in numerical oceanographic models using data assimilation (DA). So far, sea surface height (SSH) data were provided by one-dimensional nadir altimeters.

A gradual change is more likely to have caused the Mid-Pleistocene Transition than an abrupt event
Communications Earth & Environment, 2023 A gradual change in the climate system such as a decrease in atmospheric carbon dioxide is more likely to have caused the Mid-Pleistocene Transition than an abrupt event, suggest model simulations constrained by a global ice volume reconstruction over ...

Photolytic modification of seasonal nitrate isotope cycles in East Antarctica [PDF]
Atmospheric Chemistry and Physics, 2022 Nitrate in Antarctic snow has seasonal cycles in nitrogen and oxygen isotopic ratios that reflect its sources and atmospheric formation processes, and as a result, nitrate archived in Antarctic ice should have great potential to record atmospheric ...
