Reactive transport simulation of Uranium ISL at the block scale: a tool for testing designs and operation scenarios

4 novembre 2013

This study details the development of a tool simulating in the 3D fluid flow as well as the coupled physical and chemical processes in an ISL production block. The model relies on an appropriate description of uranium bearing aquifer: 3D geologic model, geostatistical simulation of hydrodynamic (...)

Relations entre eaux souterraines, cours d'eau et pergélisol au Spitsberg occidental : exemple du bassin versant du glacier Austre Lovén (79°N, Svalbard)

22 septembre 2013

Dans la zone arctique et sub - arctique, la dégradation du pergélisol est l'une des conséquences visibles du changement climatique. Elle s'associe à des flux croissants d'eau, de solutés et de sédiments qui peuvent significativement impacter les zones côtières et ainsi les océans. Le réchauffement (...)

Five consecutive years of mass balance observations to understand glacier reaction to present climate change (Austre Lovénbreen, Svalbard 79°N)

21 septembre 2013

Since 2008, mass balance is measured on the Austre Lovénbreen (Spitsbergen, Norway, 79 N) as part of the Hydro-Sensor-FlOWS program. The observations are made at a very fine scale: on the 4.5 km 2 glacier, mass balance is measured each September with 36 stakes. Snow cover is measured at the end (...)

Understanding links between snow cover and mass balance using a dense monitoring network in a small Arctic glacier basin (Austre Lovénbreen, Svalbard 79°N)

21 septembre 2013

Glacier ice is the result of successive transformations of snow. All glaciers are therefore strongly linked with seasonal snowfalls. The frequency of snowfalls, the quantities involved, and the quality of snow all have an influence on the dynamics of glaciers. Snow cover is the prime source of (...)

A terrestrial laser scanning survey to derive snow volume and water equivalent on the slopes of Austre Lovén glacier basin (Svalbard - 79°N)

21 septembre 2013

Steep slopes represent 35% of Austre Lovén glacier basin, a small valley glacier in Svalbard (79°N). Slopes and their dynamics do have an important impact on polar glaciers. They also are of high hydrological importance in the water budget of basins. One major issue in studying slopes is the fact (...)

High time and space resolution analysis of Austre Lovén glacier seasonal and interannual dynamics (Svalbard - 79°N)

21 septembre 2013

Austre Lovén glacier is a small valley glacier in Svalbard. It has been retreating since the little ice age. Over the last five years, an extensive monitoring program has been conducted in this glacier basin. A network of 36 ablation stakes has been distributed at regular intervals over the 4.5 (...)
