Interferometric synthetic aperture radar (InSAR) and its applications to study volcanoes, part 2: InSAR imaging of Alaskan Volcanoes
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...

InSAR captures rifting and volcanism in East Africa
Michael P. Poland
2006, Report, Alaska Satellite Facility News and Notes
In the past decade, synthetic aperture radar interferometric (InSAR) has enjoyed increasing use as a tool for detecting and characterizing surface deformation associated with volcanoes, earthquakes, glaciers, and other geological processes. Though InSAR can only image deformation that occurs along the radar line-of-sight and is subject to atmospheric, orbital, and...
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...

2006, Professional Paper 1709-F
The Sitka Graywacke is the westernmost and youngest unit of the Chugach accretionary complex in southeastern Alaska. Using laser-ablation inductively coupled plasma mass spectroscopy, we obtained 492 detrital-zircon ages on seven typical samples of Sitka Graywacke turbidites, which were collected in a transect across much of the unit near Sitka,...
