2005, Book chapter, Ecological Responses to the 1980 Eruption of Mount St. Helens
Geomorphic disturbances are widely recognized as important processes that influence plant-community development and landscape-scale vegetation patterns [e.g., Veblen and Ashton (1978), Garwood et al. (1979), Swanson et al. (1988), and Malanson (1993)]. In volcanically active areas such as the Pacific Northwest, mudflows are locally important geomorphic disturbance events governing short-...

Serge Andréfouët, E.J. Hochberg, Christophe Chevillon, Frank E. Muller-Karger, John Brock, Chuanmin Hu
2005, Book chapter, Remote sensing of coastal aquatic environments: technologies, techniques and applications
In this chapter we present how both direct and indirect remote sensing can be integrated to address two major coral reef applications - coral bleaching and assessment of biodiversity. This approach reflects the current non-linear integration of remote sensing for environmental assessment of coral reefs, resulting from a rapid increase...
