2009, Book chapter, Remote sensing of coastal environments
Land use/land cover (LULC) is one of the most convincing aspects of the global change that has occurred in the terrestrial ecosystem (Meyer and Turner II, 1994; IPCC, 2001). Many changes in LULC refl ect the impacts of human activities on global environment (e.g., Houghton et al., 1999). Change in...

Reconstructing Rodinia by Fitting Neoproterozoic Continental Margins
John H. Stewart
2009, Open-File Report 2009-1191
Reconstructions of Phanerozoic tectonic plates can be closely constrained by lithologic correlations across conjugate margins by paleontologic information, by correlation of orogenic belts, by paleomagnetic location of continents, and by ocean floor magmatic stripes. In contrast, Proterozoic reconstructions are hindered by the lack of some of these tools or the...
