Commonly in geomorphology measurements by different methods are compared to see how far they agree. Such assessment usually employs scatter plots, correlation and possibly regression. More appropriate and more effective methods include plotting

This paper presents a quantitative comparison of proglacial suspended sediment transport dynamics in three contrasting arctic glacier basins : one largely cold-based glacier (Austre Brøggerbreen), one largely warm-based glacier (Finsterwalderbreen
) and one intermediate polythermal glacier (Erdmannbreen). Temporal dynamics of the different suspended sediment transport systems will be inferred from the structure of statistical models which best explain the variance of proglacial suspended sediment

This paper presents a quantitative comparison of proglacial suspended sediment transport dynamics in 3 contrasting arctic glacier basins. The study sites include a largely cold-based glacier, a largely warm-based glacier and an intermediate type
of polythermal-based glacier. Temporal dynamics of the different suspended sediment transport systems will be inferred from the structure of statistical models which best explain the variance of proglacial suspended sediment concentration (SSC). This constitutes
Dynamics of soil sealing and soil landscape patterns under rapid urbanization
, especially those of the highest quality, were the first victims. Soil landscapes, at the regional scale, became more fragmented and irregular, but less dominated, diverse and connected as urbanization intensified. Spatial regression uncovered the diverging
relationships between landscape metrics with urbanization indicators and measurement period. This study provides a practical methodological framework, by integrating remote sensing, geographical information systems, landscape metrics and spatial regression
and parent material. The final digital soil maps were elaborated using regression kriging. The variance explained by the regression kriging models was estimated as 13% and 37% for soil organic carbon and clay respectively. These results were confirmed
