Jessica L. Ball, Eliza S. Calder, Bernard E. Hubbard, Marc L. Bernstein
2013, Bulletin of Volcanology (75) 676-676
A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced relatively small and infrequent dome collapses in...
Accounting for non-photosynthetic vegetation in remote-sensing-based estimates of carbon flux in wetlands
Lisa M. Schile, Kristin B. Byrd, Lisamarie Windham-Myers, Maggi Kelly
2013, Remote Sensing Letters (4) 542-551
Monitoring productivity in coastal wetlands is important due to their high carbon sequestration rates and potential role in climate change mitigation. We tested agricultural- and forest-based methods for estimating the fraction of absorbed photosynthetically active radiation (f APAR), a key parameter for modelling gross primary productivity (GPP), in a restored,...
