Enhanced basal lubrication and the contribution of the Greenland ice sheet to future sea-level rise.
We assess the effect of enhanced basal sliding on the flow and mass budget of the Greenland ice sheet, using a newly developed parameterization of the relation between meltwater runoff and ice flow. A wide range of observations suggest that water generated by melt at the surface of the ice sheet reaches its bed by both fracture and drainage through moulins. Once at the bed, this water is likely...
As for the East Asian countries, the total amount of government debt in Korea has risen sharply over the following several years in the wake of the Asian financial crisis. The purpose of this paper is to assess whether the current levels of government debt are sustainable for a severely attacked country, namely, Korea. Under the intertemporal budget constraint model, the study tests for fiscal ...
In this paper, a new model of phytoplankton growth in the chemostat is proposed. First, we give a description of the chemostat and we recall the main models: the simple Monod model, experimentally validated for bacteria growth and the Droop model, which is validated for phytoplankton growth and takes into account the possible nutrient storage. Though our model is quite similar to the Droop one,...
