Stream Organic Matter Budgets, J.R Webster, Judy L. Meyer
Long Term Ecological Research Network
This analysis of organic matter dynamics in streams has 3 objectives: 1) to explore the relationships between physical characteristics of streams and their watersheds (climate, geomorphology) and steam organic matter dynamics using data from a broad geographic area; 2) to compare steam organic matter dynamics in a diverse array of steams in order to suggest determinants of observed patterns; and 3) to reveal deficiencies in currently available data on organic matter dynamics in steams. Streams were included in this analysis not to represent the global diversity of stream types but because organic matter data were available. In the introductory chapter …

A Search For Average, Extremes, And Runs Of Unusual Weather In Iowa, R. E. Carlson, D. P. Todey
Journal of the Iowa Academy of Science: JIAS
Temperature and precipitation during the past decade have exhibited wide variation throughout Iowa. Is this unusual? An attempt was made to answer this question by computing various statistical parameters that characterize variation in Iowa's long term climatic record. Absolute deviations were used to identify the most and least variable months and years since 1900. Overall, 1936 with a very cold winter and very warm summer was the least normal year. Runs of daily weather showed that heat and cold stress could often persist for more than 1 month. Runs of dry days were much longer than runs of wet days. …
