Zhong Lu, Daniel Dzurisin, Charles W. Wicks Jr., John A. Power
2006, Science of Surveying and Mapping (31) 36-39
Interferometric synthetic aperture radar (InSAR) is a remote sensing technique which can measure ground surface deformation with sub-centimeter precision and spatial resolution in tens-of-meters over a large region. This paper summarizes our recent InSAR studies of Alaskan volcanoes, associated with both eruptive and non-eruptive activity. It shows that InSAR can...

Shorebird avoidance of nearshore feeding and roosting areas at night correlates with presence of a nocturnal avian predator
Theunis Piersma, Robert E. Gill Jr., Petra de Goeij, Anne Dekinga, Marnie Shepherd, Daniel R. Ruthrauff, T. Lee Tibbitts
2006, Wader Study Group Bulletin (109) 73-76
We here report two anecdotes about avianinteractions relevant to the interpretation of differences in shorebirdhabitat use between day and night. Several studies have reported that shorebirds avoid feeding and roosting along nearshore areasat night yet commonly use these sites during daytime. This suggests that nighttime avoidance of nearshore places is a response to increased danger...
