Over large regions of Antarctica, ice sheet and bedrock topography and the snow deposition, drift, and erosional environment combine to produce roughness on various scales. The roughness influences the microwave backscattering and emission properties of the surface, introducing azimuth-angle dependencies in the satellite observation data. In this paper we explore the use of data from SeaWinds o...
In recent years, the nature of the complex interactions between the solid earth and the overlying atmosphere has been the subject of much debate (England and Molnar 1990; Whipple et al. 1999; Braun et al. 1999). Does erosion play an important role in the dynamics of mountain building? Is there a strong feedback into the balance of forces at the crustal scale from mass transport by erosional and...
Wind erosion is important in areas with less than 150 mm of rainfall Measuring the extent and severity of wind erosion in many countries, including Iran, there is no station to measure wind erosion sediments and so the deposition estimation methods rely on empirical models so that in many cases there are measurement errors. With estimates wind and water erosion and deposition potential compared...
1. We used information theoretic statistics [Akaike’s Information Criterion (AIC)] and regression analysis in a multiple hypothesis testing approach to assess the processes capable of explaining long-term demographic variation in a lightly exploited brook trout population in Ball Creek, NC. We sampled a 100-m-long second-order site during both spring and autumn 1991–2004, using three-pass elect...
