Moving vs. Fixed Sampling Designs to Detect Environmental Health Hazards

Steven Thompson, SFU, Oct 20 2005

For detecting releases of biological pathogens and other airborne health hazards, is it better to set out sensors in fixed positions or to have them move in some pattern? Beyond simple detection of the hazard, what is the best fixed or moving pattern for characterizing the release in space and time? The more general question is what is the best design for sampling a population that is changing, when the sampling units themselves may move as observations are collected. In this talk I'll describe the motivation for the initiative that led to a study of this issue, the results of the study, and some open questions remaining.
