This report discusses the spatial distribution of the largest, most damaging floods in the United States and some of the factors that affect this distribution. Topics include regional climatology, topography, and basin size. A discussion of climatological factors includes the general northward trend of decreasing atmospheric moisture; proximity to oceanic moisture sources such as the Pacific Ocean ... Full description.

This report, part of a series that analyzes population and housing data collected from the census of 2000, highlights population size and distribution changes between 1990 and 2000 in regions, states, counties, and large cities. Data, maps, and discussion are used to examine the size of the population increase, which states and regions experienced the largest growth, where the largest proportion of ... Full description.

This report provides an overview of the exchange of greenhouse gases, their influences on climate, viability of ecosystems, distribution of biomes, quantities of surface- and ground-water, and some research projects in place to investigate these influences. Topics include lake-atmosphere carbon dioxide exchange, sequestering and exchange of atmospheric carbon dioxide in boreal and subalpine forests, ... Full description.

This report describes a structural model proposed to explain sedimentation patterns in the Trinidad area of the East Venezuelan Basin. Full description.

The Environmental Education and Training Partnership (EETAP) is a consortium of universities, non-profit organizations, and professional education associations whose efforts are focused on identifying and implementing essential educator training services for delivery of quality and professional environmental education (EE). In this study, capacity building was evaluated at the state level and the ... Full description.

This report provides the results of an evaluation of the Global Learning and Observations to Benefit the Environment (GLOBE) program. Through the evaluation, the authors identify the elements of teacher practice and goals, GLOBE partner support, and local assistance (community, district and school) that facilitate integration of GLOBE into the local curriculum, support student science inquiry and ...

Action research consists of a family of research methodologies which pursue action and research outcomes at the same time. This is a resource file which supports the regular public program "areol" (action research and evaluation on line). Using an evaluation process in the general style of action research, it illustrates some points about qualitative research and evaluation. Full description.

This document provides an extensive description of a strategy to deliver credible predictions of future atmospheric carbon dioxide levels based on improved understanding of dynamics in the Earth's carbon reservoirs (the land, air and oceans). Full description.

Starting in 1992, introductory physics students at Indiana University were pre- and post-tested on their knowledge of general physics. Some students received standard classes of lectures and tests, while others were taught using interactive engagement (IE) techniques. The goal of the study was this: can IE methods increase the effectiveness of introductory mechanics courses? Though the study focused ... Full description.

In this report, the Global Fluid Dynamics Laboratory Climate Research Group examines the possible climate impacts of quadrupling atmospheric CO2. Several impacts are discussed, surface air temperature warming, sea level rise, thermohaline circulation changes, mid-latitude summer drying, heat index and temperature increases and possible changes in tropical storms and El Nino. This site provides a nice ... Full description.
